A previous biodistance study has suggested that the population of the town consisted of a polyethnic amalgam of immigrant and indigenous. In this study, we use biogeochemistry to investigate paleomobility and paleodiet in archeological human remains from the ninth to eleventh century levels at the sites at Fishamble Street II (National Museum of Ireland excavation number E172), Fishamble Street III (E190) and John's Lane (E173), as well as twelfth-century remains from Wood Quay (E132).

To test hypotheses related to intrapopulation variation in foraging or the presence of diet specialization, we conducted stable isotope analysis (d 13 C, d 15 N) on hair and claw samples from 51 grizzly bears (Ursus arctos) collected from 2003 to 2006 in the Mackenzie Delta region of the Canadian Arctic. We examined within-population differences in the foraging patterns of males and females and the relationship between trophic position (derived from d 15 N measurements) and individual movement. The range of d 15 N values in hair and claw (2.0-11.0%) suggested a wide niche width and cluster analyses indicated the presence of three foraging groups within the population, ranging from nearcomplete herbivory to near-complete carnivory. We found no linear relationship between home range size and trophic position when the data were continuous or when grouped by foraging behavior. However, the movement rate of females increased linearly with trophic position. We used multisource dual-isotope mixing models to determine the relative contributions of seven prey sources within each foraging group for both males and females. The mean bear dietary endpoint across all foraging groups for each sex fell toward the center of the mixing polygon, which suggested relatively well-mixed diets. The primary dietary difference across foraging groups was the proportional contribution of herbaceous foods, which decreased for both males and females from 42-76 to 0-27% and 62-81 to 0-44%, respectively. Grizzlies of the Mackenzie Delta live in extremely harsh conditions and identifying within-population diet specialization has improved our understanding of varying habitat requirements within the population.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/47217940" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="88477cb69e2c0d875b5147d9a8cbc918" rel="nofollow" data-download="{"attachment_id":66434167,"asset_id":47217940,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/66434167/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="30731376" href="https://independent.academia.edu/HobsonKeith">Keith Hobson</a><script data-card-contents-for-user="30731376" type="text/json">{"id":30731376,"first_name":"Keith","last_name":"Hobson","domain_name":"independent","page_name":"HobsonKeith","display_name":"Keith Hobson","profile_url":"https://independent.academia.edu/HobsonKeith?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_47217940 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="47217940"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 47217940, container: ".js-paper-rank-work_47217940", });

To test hypotheses related to intrapopulation variation in foraging or the presence of diet specialization, we conducted stable isotope analysis (d 13 C, d 15 N) on hair and claw samples from 51 grizzly bears (Ursus arctos) collected from 2003 to 2006 in the Mackenzie Delta region of the Canadian Arctic. We examined within-population differences in the foraging patterns of males and females and the relationship between trophic position (derived from d 15 N measurements) and individual movement. The range of d 15 N values in hair and claw (2.0-11.0%) suggested a wide niche width and cluster analyses indicated the presence of three foraging groups within the population, ranging from nearcomplete herbivory to near-complete carnivory. We found no linear relationship between home range size and trophic position when the data were continuous or when grouped by foraging behavior. However, the movement rate of females increased linearly with trophic position. We used multisource dual-isotope mixing models to determine the relative contributions of seven prey sources within each foraging group for both males and females. The mean bear dietary endpoint across all foraging groups for each sex fell toward the center of the mixing polygon, which suggested relatively well-mixed diets. The primary dietary difference across foraging groups was the proportional contribution of herbaceous foods, which decreased for both males and females from 42-76 to 0-27% and 62-81 to 0-44%, respectively. Grizzlies of the Mackenzie Delta live in extremely harsh conditions and identifying within-population diet specialization has improved our understanding of varying habitat requirements within the population.","downloadable_attachments":[{"id":66434167,"asset_id":47217940,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":30731376,"first_name":"Keith","last_name":"Hobson","domain_name":"independent","page_name":"HobsonKeith","display_name":"Keith Hobson","profile_url":"https://independent.academia.edu/HobsonKeith?f_ri=1703","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":1703,"name":"Stable Isotope Analysis","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Analysis?f_ri=1703","nofollow":true},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology?f_ri=1703","nofollow":true},{"id":11417,"name":"Population Dynamics","url":"https://www.academia.edu/Documents/in/Population_Dynamics?f_ri=1703","nofollow":true},{"id":17889,"name":"Carnivora","url":"https://www.academia.edu/Documents/in/Carnivora?f_ri=1703","nofollow":true},{"id":19652,"name":"Ecological Niche Modeling","url":"https://www.academia.edu/Documents/in/Ecological_Niche_Modeling?f_ri=1703"},{"id":46271,"name":"Strategy","url":"https://www.academia.edu/Documents/in/Strategy?f_ri=1703"},{"id":54114,"name":"Canada","url":"https://www.academia.edu/Documents/in/Canada?f_ri=1703"},{"id":78117,"name":"Carbon Isotopes","url":"https://www.academia.edu/Documents/in/Carbon_Isotopes?f_ri=1703"},{"id":133873,"name":"Plants","url":"https://www.academia.edu/Documents/in/Plants?f_ri=1703"},{"id":202574,"name":"Feeding Behavior","url":"https://www.academia.edu/Documents/in/Feeding_Behavior?f_ri=1703"},{"id":223041,"name":"Oecologia","url":"https://www.academia.edu/Documents/in/Oecologia?f_ri=1703"},{"id":226765,"name":"Nitrogen Isotopes","url":"https://www.academia.edu/Documents/in/Nitrogen_Isotopes?f_ri=1703"},{"id":363556,"name":"Foraging Behavior","url":"https://www.academia.edu/Documents/in/Foraging_Behavior?f_ri=1703"},{"id":971655,"name":"Grizzly Bear","url":"https://www.academia.edu/Documents/in/Grizzly_Bear?f_ri=1703"},{"id":1013028,"name":"Food Chain","url":"https://www.academia.edu/Documents/in/Food_Chain?f_ri=1703"},{"id":2143496,"name":"Herbivore","url":"https://www.academia.edu/Documents/in/Herbivore?f_ri=1703"},{"id":2196834,"name":"Canadian Arctic","url":"https://www.academia.edu/Documents/in/Canadian_Arctic?f_ri=1703"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_32920137" data-work_id="32920137" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/32920137/Species_co_occurrence_affects_the_trophic_interactions_of_two_juvenile_reef_shark_species_in_tropical_lagoon_nurseries_in_Moorea_French_Polynesia">Species co-occurrence affects the trophic interactions of two juvenile reef shark species in tropical lagoon nurseries in Moorea (French Polynesia</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Food web structure is shaped by interactions within and across trophic levels.

As such, understanding how the presence and absence of predators, prey, and competitors affect species foraging patterns is important for predicting the consequences of changes in species abundances, distributions, and behaviors. Here, we used plasma d 13 C and d 15 N values from juvenile blacktip reef sharks (Carcharhinus melanopterus) and juvenile sicklefin lemon sharks (Negaprion acutidens) to investigate how species co-occurrence affects their trophic interactions in littoral waters of Moorea, French Polynesia. Co-occurrence led to isotopic niche partitioning among sharks within nurseries, with significant increases in d 15 N values among sicklefin lemon sharks, and significant decreases in d 15 N among blacktip reef sharks. Niche segregation likely promotes coexistence of these two predators during early years of growth and development, but data do not suggest coexistence affects life history traits, such as body size, body condition, and ontogenetic niche shifts. Plasticity in trophic niches among juvenile blacktip reef sharks and sicklefin lemon sharks also suggests these predators are able to account for changes in community structure, resource availability, and intra-guild competition, and may fill similar functional roles in the absence of the other species, which is important as environmental change and human impacts persist in coral reef ecosystems.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/32920137" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="946a86d0b60e9a9119cd8501d0935e29" rel="nofollow" data-download="{"attachment_id":53054970,"asset_id":32920137,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/53054970/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="1104323" href="https://mq.academia.edu/JohannMourier">Johann Mourier</a><script data-card-contents-for-user="1104323" type="text/json">{"id":1104323,"first_name":"Johann","last_name":"Mourier","domain_name":"mq","page_name":"JohannMourier","display_name":"Johann Mourier","profile_url":"https://mq.academia.edu/JohannMourier?f_ri=1703","photo":"https://0.academia-photos.com/1104323/384408/712239/s65_johann.mourier.jpg"}</script></span></span></li><li class="js-paper-rank-work_32920137 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="32920137"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 32920137, container: ".js-paper-rank-work_32920137", });

In this study, we examine the impacts of the trophic ecology of non-native fishes on the 'three species' in the San Rafael River, Utah, USA. We employ a suite of abundance comparisons, stable isotope techniques and size-at-age back-calculation analyses to compare food web structure and growth rates of the 'three species' in study areas with and without established populations of non-native species. We found that the 'three species' are more abundant in areas with few non-native fishes present, regardless of habitat complexity. Stable isotope analyses indicate non-native fishes lengthen the food chain by 0.5 trophic positions. Further, the trophic niche spaces of the native fishes shift and are narrower in the presence of non-native fishes, as several non-native species' trophic niche spaces overlap almost entirely with each of the 'three species' (bluehead sucker and flannelmouth sucker 100%, roundtail chub 98.5%) indicating strong potential for competition. However, the 'three species' demonstrated no evidence of reduced growth in the presence of these non-native fishes. Collectively, these results suggest that while non-native fishes alter the food web structure presenting novel sources of predation and competition, mechanisms other than competition are controlling the size-structure of 'three species' populations in the San Rafael River.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/32755978" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="963d61443be966eb9a92e91420b8b2f4" rel="nofollow" data-download="{"attachment_id":52913381,"asset_id":32755978,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/52913381/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="63674646" href="https://independent.academia.edu/PhaedraBudy">Phaedra Budy</a><script data-card-contents-for-user="63674646" type="text/json">{"id":63674646,"first_name":"Phaedra","last_name":"Budy","domain_name":"independent","page_name":"PhaedraBudy","display_name":"Phaedra Budy","profile_url":"https://independent.academia.edu/PhaedraBudy?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_32755978 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="32755978"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 32755978, container: ".js-paper-rank-work_32755978", });

The metabolic balance of an individual can impact isotopic signals in tissues that are forming during the periods of metabolic stress. Fluctuating δ15N values are associated with physiological stressors that alter an individual's metabolism such as infection, injury, or pregnancy. This study examines variation in δ13C and δ15N values along sequentially segmented hair in both modern and archaeological individuals. Subjects with an observable skeletal pathology, known chronic illness, or evidence of pregnancy were compared with controls exhibiting no evidence of physiological stress. The results on hair samples from individuals from 19th century Belleville, Ontario, four modern cadavers (two with cancer and two sudden deaths), and two living pregnant women indicate that δ15N values are approximately 1‰ higher in individuals with a pathological condition (e.g., infection, fracture, or cancer) and are 1‰ lower during pregnancy, whereas δ13C values show less variability. Higher nitrogen values may represent the recycling of nitrogen derived from the breakdown of existing proteins in the body (catabolism), whereas lower δ15N values are related to increased utilization of dietary and urea nitrogen for tissue synthesis during pregnancy. These findings suggest that short-term fluctuations of δ15N values may be the result of changes in an individual's metabolic balance, and that metabolic imbalance poses a confounding factor to ancient dietary studies when using rapidly growing tissues such as hair.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/11081093" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="393c9b984cff6f8f5a32ae98ebaa689a" rel="nofollow" data-download="{"attachment_id":50064113,"asset_id":11081093,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50064113/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="32445" href="https://mcmaster.academia.edu/TracyProwse">Tracy Prowse</a><script data-card-contents-for-user="32445" type="text/json">{"id":32445,"first_name":"Tracy","last_name":"Prowse","domain_name":"mcmaster","page_name":"TracyProwse","display_name":"Tracy Prowse","profile_url":"https://mcmaster.academia.edu/TracyProwse?f_ri=1703","photo":"https://0.academia-photos.com/32445/10503/139609691/s65_tracy.prowse.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-11081093">+1</span><div class="hidden js-additional-users-11081093"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://mcmaster.academia.edu/LoriDOrtenzio">Lori D'Ortenzio</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-11081093'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-11081093').html();

These findings suggest that short-term fluctuations of δ15N values may be the result of changes in an individual's metabolic balance, and that metabolic imbalance poses a confounding factor to ancient dietary studies when using rapidly growing tissues such as hair.","downloadable_attachments":[{"id":50064113,"asset_id":11081093,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":32445,"first_name":"Tracy","last_name":"Prowse","domain_name":"mcmaster","page_name":"TracyProwse","display_name":"Tracy Prowse","profile_url":"https://mcmaster.academia.edu/TracyProwse?f_ri=1703","photo":"https://0.academia-photos.com/32445/10503/139609691/s65_tracy.prowse.png"},{"id":471706,"first_name":"Lori","last_name":"D'Ortenzio","domain_name":"mcmaster","page_name":"LoriDOrtenzio","display_name":"Lori D'Ortenzio","profile_url":"https://mcmaster.academia.edu/LoriDOrtenzio?f_ri=1703","photo":"https://0.academia-photos.com/471706/3350450/3942405/s65_lori.d_ortenzio.jpg"}],"research_interests":[{"id":1703,"name":"Stable Isotope Analysis","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Analysis?f_ri=1703","nofollow":true},{"id":1704,"name":"Bioarchaeology","url":"https://www.academia.edu/Documents/in/Bioarchaeology?f_ri=1703","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_9199802" data-work_id="9199802" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/9199802/Oxygen_isotopes_in_ferric_oxides_from_recent_soil_hydrologic_and_marine_environments">Oxygen isotopes in ferric oxides from recent soil, hydrologic, and marine environments</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Low-temperature synthesis experiments on ferric oxide–water systems have resulted in disparate oxygen isotope fractionation–temperature (α-T) curves.

In this study, recent ferric oxides, mostly goethites of Holocene age, were collected and analyzed from a variety of modern soil, stream, and marine environments, where formation temperature and the oxygen isotopic composition (δ18O) of the water from which ferric oxides precipitated can be independently measured or estimated. This allows comparison of experimental α-T relationships with data from natural systems. <br /> <br />Selective dissolution methods were refined for the pretreatment of fine-grained minerals in order to obtain reliable δ18O values for pure and crystalline ferric oxides. The difference (Δδ18O) between the δ18O value of goethite and that of local mean meteoric water ranges from −1.5 to +6.3‰ for soil goethites from New Jersey, Indiana, Michigan, Iowa, South Dakota, and Taiwan. We argue that these variations are largely the result of differences between the δ18O of formation water and that of local mean meteoric water, induced probably by 18O-enrichment of soil waters by evaporation or other processes in soil horizons where ferric oxides are forming. A marine goethite sample from Scotland and a subaqueous bog iron sample from New Jersey, which can not be biased by evaporative processes, provide crucial natural evidence that the difference in δ18O between goethite and formation water is ∼−1.5‰ at ∼10°C. This result is consistent with our prior laboratory synthesis results (Bao and Koch, 1999), but in conflict with other experimental calibrations. Given the highly variable δ18O value of soil or other surface water, as well as the potential of initially formed ferric oxides for reequilibration with subsurface burial fluids during maturation to crystalline phases, an understanding of formational and diagenetic conditions is absolutely essential when attempting to use the oxygen isotope composition of ferric oxides as a paleoclimatic proxy.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9199802" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="e086843d8b4d32b50e244efdaa58bb10" rel="nofollow" data-download="{"attachment_id":35480434,"asset_id":9199802,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/35480434/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="1197806" href="https://ucsc.academia.edu/PaulKoch">Paul Koch</a><script data-card-contents-for-user="1197806" type="text/json">{"id":1197806,"first_name":"Paul","last_name":"Koch","domain_name":"ucsc","page_name":"PaulKoch","display_name":"Paul Koch","profile_url":"https://ucsc.academia.edu/PaulKoch?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_9199802 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9199802"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9199802, container: ".js-paper-rank-work_9199802", });

The faunal remains analyzed were recovered from eight archaeological sites in three distinct ecological settings in Siberia and the Russian Far East. The archaeological record of these sites recorded thousands of years of human-animal interactions, from the hunter-fisher-gatherer societies of the Neolithic along the coast of southern Primorye, to Iron Age dog sledding groups at the Arctic Circle in the Lower Ob, to the agricultural peoples of Transbaiikal and Primorye during the medieval period. Samples were selected to reflect the suite of taxa represented at each site and include both domestic and wild animal species, as well as aquatic and terrestrial fauna. The values reported in this study are among the first faunal comparative stable isotope data for these areas. In addition to the faunal skeletal samples, human skeletal samples from two sites were also available, providing an opportunity to explore the utility of animal dietary stable isotope values as proxies for human ones.<br /><br />The results of this study demonstrate local strategies to animal management in each of the three regions and highlight the human use of locally available resources to provision domestic animals. At Ust’-Polui, Iron Age peoples likely relied upon the abundant fishery provided by the Ob River to feed sled dogs, which require massive quantities of dietary resources to perform labour in extreme temperatures. Inferences from the medieval Proezzhaia I hillfort in Transbaikal suggest dogs, pigs, and caprines provisioned themselves, while horses and cattle may have been provided with supplemental fodder or given access to pasture. In southern Primorye, human dietary stable isotope data indicate Late Neolithic and Early Iron Age peoples relied on high trophic level marine resources, at odds with the abundance of shellfish remains at Boisman II and Pospelovo I. Additional data from other coastal shell midden sites and the inland Cherniatino II show no dietary isotopic separation of suids over thousands of years, suggesting the local environment provided adequate accommodation for the management of domestic pigs with natural resources. However, the dietary stable isotope data from Cherniatino II show extensive use of cultivated millet among other domestic species, particularly during medieval occupation of the site.<br /><br />The dietary stable isotope data generated by this study provide some support for the use of animal δ13C and δ15N values as proxy information for contemporaneous human diets, particularly those of domestic dogs.

The faunal remains analyzed were recovered from eight archaeological sites in three distinct ecological settings in Siberia and the Russian Far East. The archaeological record of these sites recorded thousands of years of human-animal interactions, from the hunter-fisher-gatherer societies of the Neolithic along the coast of southern Primorye, to Iron Age dog sledding groups at the Arctic Circle in the Lower Ob, to the agricultural peoples of Transbaiikal and Primorye during the medieval period. Samples were selected to reflect the suite of taxa represented at each site and include both domestic and wild animal species, as well as aquatic and terrestrial fauna. The values reported in this study are among the first faunal comparative stable isotope data for these areas. In addition to the faunal skeletal samples, human skeletal samples from two sites were also available, providing an opportunity to explore the utility of animal dietary stable isotope values as proxies for human ones.\n\nThe results of this study demonstrate local strategies to animal management in each of the three regions and highlight the human use of locally available resources to provision domestic animals. At Ust’-Polui, Iron Age peoples likely relied upon the abundant fishery provided by the Ob River to feed sled dogs, which require massive quantities of dietary resources to perform labour in extreme temperatures. Inferences from the medieval Proezzhaia I hillfort in Transbaikal suggest dogs, pigs, and caprines provisioned themselves, while horses and cattle may have been provided with supplemental fodder or given access to pasture. In southern Primorye, human dietary stable isotope data indicate Late Neolithic and Early Iron Age peoples relied on high trophic level marine resources, at odds with the abundance of shellfish remains at Boisman II and Pospelovo I. Additional data from other coastal shell midden sites and the inland Cherniatino II show no dietary isotopic separation of suids over thousands of years, suggesting the local environment provided adequate accommodation for the management of domestic pigs with natural resources. However, the dietary stable isotope data from Cherniatino II show extensive use of cultivated millet among other domestic species, particularly during medieval occupation of the site.\n\nThe dietary stable isotope data generated by this study provide some support for the use of animal δ13C and δ15N values as proxy information for contemporaneous human diets, particularly those of domestic dogs. Though humans and dogs from Ust’-Polui, Boisman II, and Pospelovo I broadly shared dietary inputs from aquatic resources, consistent δ13C and δ15N value offsets between the two hint at more specific provisioning practices.","downloadable_attachments":[{"id":80985210,"asset_id":71783845,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":279747,"first_name":"Lacey","last_name":"Fleming","domain_name":"ualberta","page_name":"LaceyFleming","display_name":"Lacey S .

Additional belemnite carbon isotope ratios from the Izhma River succession (also Ryazanian–Valanginian) in Russia are also presented. The wood-derived and belemnite-derived isotope ratios are considered to primarily reflct changes in the terrestrial and marine carbon isotope reservoirs respectively. The δ13Ccarb and δ13Cwood records reveal a distinct mid-Valanginian positive carbon isotope excursion, with the initiation occurring near the Boreal Russian michalskii–polyptychus zone boundary, which is broadly time-equivalent Tethyan campylotoxus–verrucosum boundary. The Ryazanian–Valanginian δ13Ccarb values fluctuate between c. –1 and +1.5‰ but reach a maximum of +4.1‰ in the Late Valanginian, whilst the δ13Cwood values fluctuate between c.–27 and –23.5‰ and reach a Late Valanginian maximum of –21.2‰. The excursion maximum in the Boreal Russian bidichotomus zones corresponds with the peak of the Tethyan marine carbonate excursion in the verrucosum–eperegrinus zones, the peak of a marine carbonate excursion recorded in the Argentinean atherstoni Zone and also with the peak of a terrestrial organic carbon isotope excursion in the Crimean trinodosum–ecallidiscus ammonite zones. The synchroneity of the positive carbon isotope event between the marine and terrestrial records and between the northern and southern hemispheres and Tethys, clearly indicates a strong coupling of the ocean-atmosphere system at this time and also confirms that this was a global event, which would have affected the total exchangeable carbon reservoir.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/1029287" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="84ed068d33e82c65f5cd30da4165f38a" rel="nofollow" data-download="{"attachment_id":7267597,"asset_id":1029287,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/7267597/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="856422" href="https://durham.academia.edu/DarrenGrocke">Darren Gröcke</a><script data-card-contents-for-user="856422" type="text/json">{"id":856422,"first_name":"Darren","last_name":"Gröcke","domain_name":"durham","page_name":"DarrenGrocke","display_name":"Darren Gröcke","profile_url":"https://durham.academia.edu/DarrenGrocke?f_ri=1703","photo":"https://0.academia-photos.com/856422/305249/1342118/s65_darren.gr_cke.jpg"}</script></span></span></li><li class="js-paper-rank-work_1029287 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="1029287"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 1029287, container: ".js-paper-rank-work_1029287", });

The wood-derived and belemnite-derived isotope ratios are considered to primarily reflct changes in the terrestrial and marine carbon isotope reservoirs respectively. The δ13Ccarb and δ13Cwood records reveal a distinct mid-Valanginian positive carbon isotope excursion, with the initiation occurring near the Boreal Russian michalskii–polyptychus zone boundary, which is broadly time-equivalent Tethyan campylotoxus–verrucosum boundary. The Ryazanian–Valanginian δ13Ccarb values fluctuate between c. –1 and +1.5‰ but reach a maximum of +4.1‰ in the Late Valanginian, whilst the δ13Cwood values fluctuate between c.–27 and –23.5‰ and reach a Late Valanginian maximum of –21.2‰.

The mammalian biostratigraphy of Polecat Bench sediments has been well documented, and includes a major reorganization of faunas at or near the P-E boundary. To complement the existing biostratigraphy, we measured the isotopic composition of paleosol carbonate nodules at soil-by-soil temporal resolution through the P-E boundary interval. These measurements provide a detailed record of the abrupt, transient, carbon isotope excursion that affected atmospheric and oceanic carbon reservoirs at ca. 55 million years before present [Ma]. Tests of soil thickness and diagenesis indicate that trends in the record are primary, and reflect syndepositional changes in the delta (super 13) C value of atmospheric CO (sub 2) . The carbon isotope record suggests that the delta (super 13) C value of atmospheric CO (sub 2) dropped by ca. 8 per mil during this interval, and then rebounded. The pattern of change is very similar to that of an independent high-resolution record of Bains et al. (submitted). Changes in the delta (super 18) O of paleosol carbonates are consistent with a significant increase in local mean annual temperature during the P-E boundary event. Comparison of biotic and isotopic stratigraphies on Polecat Bench shows that faunal changes at the P-E boundary lag behind major events in the carbon and oxygen isotope records by about 10 thousand years [k.y.].</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9200361" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3bb84bdbaeb390304577aec0081a3c60" rel="nofollow" data-download="{"attachment_id":35480916,"asset_id":9200361,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/35480916/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="1197806" href="https://ucsc.academia.edu/PaulKoch">Paul Koch</a><script data-card-contents-for-user="1197806" type="text/json">{"id":1197806,"first_name":"Paul","last_name":"Koch","domain_name":"ucsc","page_name":"PaulKoch","display_name":"Paul Koch","profile_url":"https://ucsc.academia.edu/PaulKoch?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_9200361 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9200361"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9200361, container: ".js-paper-rank-work_9200361", });

The study supports the conclusions and widens the results <br />of our earlier limited study, i.e., that the diet of the Norse Greenlanders became more dependent on marine resources over <br />time. The isotope data provide information at the level of the individual, and the study indicates that the Norse Greenlanders <br />had an isotopically varied diet; there is no evidence that these differences were linked to sex or age. The shift in diet <br />seems to have happened gradually, perhaps beginning during the initial settlement. The swiftness of the change, however, <br />depended on where the immigrants settled; settlers in the southern part of the Eastern Settlement and in the Western Settlement <br />may have adapted to the marine resources more rapidly than those in the central Eastern Settlement region. Social <br />differences may partly explain the isotopically varied diet within Norse society; this explanation is, however, not without <br />its reservations. Despite the changes in the dietary economy, and the increasing dependence on the marine resources, farming <br />strategies remained unchanged.

The study supports the conclusions and widens the results\r\nof our earlier limited study, i.e., that the diet of the Norse Greenlanders became more dependent on marine resources over\r\ntime. The isotope data provide information at the level of the individual, and the study indicates that the Norse Greenlanders\r\nhad an isotopically varied diet; there is no evidence that these differences were linked to sex or age. The shift in diet\r\nseems to have happened gradually, perhaps beginning during the initial settlement. The swiftness of the change, however,\r\ndepended on where the immigrants settled; settlers in the southern part of the Eastern Settlement and in the Western Settlement\r\nmay have adapted to the marine resources more rapidly than those in the central Eastern Settlement region. Social\r\ndifferences may partly explain the isotopically varied diet within Norse society; this explanation is, however, not without\r\nits reservations. Despite the changes in the dietary economy, and the increasing dependence on the marine resources, farming\r\nstrategies remained unchanged. Climate change and unsustainable land-use practices have been proposed as two of the\r\nmain reasons for the depopulation of the Norse Greenland settlements in the late 1400s, and it is obvious to draw attention\r\nto these factors when trying to explain the changes in the dietary economy. It is, however, more doubtful whether the\r\nenvironmental changes were, after all, the sole cause of the depopulation of the Norse Greenland settlement. The Norse\r\nGreenlanders apparently adapted well to their physical environment, and they could survive on the marine resources in as\r\nfar as they were available.\"","downloadable_attachments":[{"id":34212700,"asset_id":4634056,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":3488424,"first_name":"Jette","last_name":"Arneborg","domain_name":"natmus","page_name":"JetteArneborg","display_name":"Jette Arneborg","profile_url":"https://natmus.academia.edu/JetteArneborg?f_ri=1703","photo":"https://0.academia-photos.com/3488424/3859850/4515546/s65_jette.arneborg.jpg"}],"research_interests":[{"id":1703,"name":"Stable Isotope Analysis","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Analysis?f_ri=1703","nofollow":true},{"id":36272,"name":"Stable Isotopes in Foodwebs","url":"https://www.academia.edu/Documents/in/Stable_Isotopes_in_Foodwebs?f_ri=1703","nofollow":true},{"id":57421,"name":"Norse Greenland","url":"https://www.academia.edu/Documents/in/Norse_Greenland?f_ri=1703","nofollow":true},{"id":652519,"name":"Norse settlement in Greenland and the wider North Atlantic","url":"https://www.academia.edu/Documents/in/Norse_settlement_in_Greenland_and_the_wider_North_Atlantic?f_ri=1703","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_71476747" data-work_id="71476747" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/71476747/Diet_and_Radiocarbon_Dating_of_Tollund_Man_New_Analyses_of_an_Iron_Age_Bog_Body_from_Denmark">Diet and Radiocarbon Dating of Tollund Man: New Analyses of an Iron Age Bog Body from Denmark</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">ABSTRACTTollund Man is one of the most famous Iron Age bog bodies due to his well-preserved head.

Case studies describe an array of applications, many of which were developed by the author himself. They include cases in which isotope profiling was used in murder, and drugs-related crime investigations, as well as for pharmaceutical and food authenticity control studies.<br /><br />Updated with coverage of exciting advances occurring in the field since the publication of the 1st edition, this 2nd edition explores innovative new techniques and applications in forensic isotope profiling, as well as key findings from original research. More than a simple update, though, this edition has been significantly revised in order to address serious problems that can arise from non-comparable and unfit-for-purpose stable isotope data. To that end, Part II has been virtually rewritten with greater emphasis now being placed on important quality control issues in stable isotope analysis in general and forensic stable isotope analysis in particular.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/33993221" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="40e1722fc8806c648fef51c8520dfb54" rel="nofollow" data-download="{"attachment_id":56202494,"asset_id":33993221,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/56202494/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="32546" href="https://rgu.academia.edu/WolframMeierAugenstein">Wolfram Meier-Augenstein</a><script data-card-contents-for-user="32546" type="text/json">{"id":32546,"first_name":"Wolfram","last_name":"Meier-Augenstein","domain_name":"rgu","page_name":"WolframMeierAugenstein","display_name":"Wolfram Meier-Augenstein","profile_url":"https://rgu.academia.edu/WolframMeierAugenstein?f_ri=1703","photo":"https://0.academia-photos.com/32546/10537/9922/s65_wolfram.meier-augenstein.jpg"}</script></span></span></li><li class="js-paper-rank-work_33993221 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="33993221"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 33993221, container: ".js-paper-rank-work_33993221", });

We analyzed the stable-isotope composition of tooth enamel from several early members of each group to reconstruct the dietary, foraging, and habitat preferences of basal taxa. Carbon isotope (␦ 13 C) values provided evidence of foraging within freshwater, terrestrial, and marine environments, including seagrass beds, whereas oxygen isotope (␦ 18 O) variation was used as a measure of commitment to aquatic habitats. Enamel samples were collected from four regions (south Asia, north and west Africa, and southern Europe) spanning the late early Eocene (ca. 53.5 Ma) to the late Eocene (ca. 36 Ma). Sirenian and cetacean taxa included species that were likely capable of some terrestrial locomotion, and more specialized forms that were morphologically fully aquatic. Cetacean ␦ 13 C and ␦ 18 O values indicate that some early members of this group (some pakicetids) inhabited freshwater environments, but later members (e.g., remingtonocetids, protocetids, and basilosaurids) moved quickly into estuarine and marine environments. Low ␦ 18 O variation confirms that all of these early forms were primarily aquatic, but ␦ 13 C and ␦ 18 O values for early sirenians indicate an early transition to a marine seagrass diet without any evidence of an intermediate connection to freshwater habitats.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/3306630" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="68b89de8b0db0a439b24bc6bde072026" rel="nofollow" data-download="{"attachment_id":31141020,"asset_id":3306630,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/31141020/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="169044" href="https://uwyo.academia.edu/MarkClementz">Mark Clementz</a><script data-card-contents-for-user="169044" type="text/json">{"id":169044,"first_name":"Mark","last_name":"Clementz","domain_name":"uwyo","page_name":"MarkClementz","display_name":"Mark Clementz","profile_url":"https://uwyo.academia.edu/MarkClementz?f_ri=1703","photo":"https://0.academia-photos.com/169044/1393757/3140063/s65_mark.clementz.jpg"}</script></span></span></li><li class="js-paper-rank-work_3306630 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="3306630"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 3306630, container: ".js-paper-rank-work_3306630", });

It is often observed that more decomposed soil organic matter is 13 C, and especially 15 N-enriched relative to fresh litter and recent organic matter. We investigated whether this shift in isotope composition relates to the isotope composition of the microbial biomass, an important source for soil organic matter. We developed a new approach to determine the natural abundance C and N isotope composition of the microbial biomass across a broad range of soil types, vegetation, and climates. We found consistently that the soil microbial biomass was 15 N-enriched relative to the total (3.2 %) and extractable N pools (3.7 %), and 13 C-enriched relative to the extractable C pool (2.5 %). The microbial biomass was also 13 C-enriched relative to total C for soils that exhibited a C3-plant signature (1.6 %), but 13 C-depleted for soils with a C4 signature (À1.1 %). The latter was probably associated with an increase of annual C3 forbs in C4 grasslands after an extreme drought. These findings are in agreement with the proposed contribution of microbial products to the stabilized soil organic matter and may help explain the shift in isotope composition during soil organic matter formation. r</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/12640386" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="47831819a1a5b5ccce44037dc1436670" rel="nofollow" data-download="{"attachment_id":46033085,"asset_id":12640386,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46033085/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="31619589" href="https://independent.academia.edu/BruceAHungate">Bruce A Hungate</a><script data-card-contents-for-user="31619589" type="text/json">{"id":31619589,"first_name":"Bruce A","last_name":"Hungate","domain_name":"independent","page_name":"BruceAHungate","display_name":"Bruce A Hungate","profile_url":"https://independent.academia.edu/BruceAHungate?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-12640386">+1</span><div class="hidden js-additional-users-12640386"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/OMenyailo">O.

It is often observed that more decomposed soil organic matter is 13 C, and especially 15 N-enriched relative to fresh litter and recent organic matter. We investigated whether this shift in isotope composition relates to the isotope composition of the microbial biomass, an important source for soil organic matter. We developed a new approach to determine the natural abundance C and N isotope composition of the microbial biomass across a broad range of soil types, vegetation, and climates. We found consistently that the soil microbial biomass was 15 N-enriched relative to the total (3.2 %) and extractable N pools (3.7 %), and 13 C-enriched relative to the extractable C pool (2.5 %). The microbial biomass was also 13 C-enriched relative to total C for soils that exhibited a C3-plant signature (1.6 %), but 13 C-depleted for soils with a C4 signature (À1.1 %).

hidden">Stable isotope analysis of organic materials for their hydrogen (2H), carbon (13C), nitrogen (15N) or oxygen (18O) isotopic composition using continuous flow isotope ratio mass spectrometry (CF-IRMS) is an increasingly used tool in forensic chemical analysis. 2H isotopic analysis can present a huge challenge, especially when dealing with exhibits comprising exchangeable hydrogen such as human scalp hair. However, to yield forensic data that are fit for purpose, analysis of the 2H isotopic composition of the same homogeneous human hair sample by any laboratory worldwide must yield the same isotopic composition within analytical uncertainty. This paper presents longitudinal 2H isotope data for four human hair samples of different provenance, measured by three different laboratories whose sample preparation was based on a two-stage H exchange equilibration method. Although each laboratory employed varying means to comply with the generic features of the sample preparation protocol such as the 2H isotopic composition of exchange waters or drying down of samples prior to analysis, within each laboratory the Principle of Identical Treatment (P.I.T.) was applied for each individual experiment. Despite the variation in materials and procedures employed by the three laboratories, repeatable and reproducible ‘true’ 2H isotope values (δ2H hair,true) were determined by each laboratory for each of the four stock samples of human scalp hair. The between-laboratory differences for obtained δ2Hhair,true values ranged from 0.1 to 2.5 %. With an overall 95% confidence interval of +/- 2.8 %, these differences were not significantly different, which suggests that the generalmethod of two-stage exchange equilibration carried out at ambient temperature is suitable for accurately and reproducibly determining ‘true’ δ2H-values for hair and other proteins provided that certain key conditions are met.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/983260" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="59910b534da64431623bc2620e636d28" rel="nofollow" data-download="{"attachment_id":6015524,"asset_id":983260,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/6015524/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="32546" href="https://rgu.academia.edu/WolframMeierAugenstein">Wolfram Meier-Augenstein</a><script data-card-contents-for-user="32546" type="text/json">{"id":32546,"first_name":"Wolfram","last_name":"Meier-Augenstein","domain_name":"rgu","page_name":"WolframMeierAugenstein","display_name":"Wolfram Meier-Augenstein","profile_url":"https://rgu.academia.edu/WolframMeierAugenstein?f_ri=1703","photo":"https://0.academia-photos.com/32546/10537/9922/s65_wolfram.meier-augenstein.jpg"}</script></span></span></li><li class="js-paper-rank-work_983260 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="983260"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 983260, container: ".js-paper-rank-work_983260", });

The Paleolithic layers in this cave were studied using a suite of mineralogical and chemical techniques and a contextual sedimentological analysis (i.e., micromorphology). We show that the lower ca. 3 m of the stratigraphic sequence are dominated by clastic sediments deposited within a closed karstic environment. The deposits were formed by small-scale, concentrated mud slurries (infiltrated terra rosa soil) and debris flows. A few intervening lenses of mostly in situ burnt remains were also identified. The main part of the upper ca. 4.5 m consists of anthropogenic sediment with only moderate amounts of clastic geogenic inputs. The deposits are strongly cemented with calcite that precipitated from dripping water. The anthropogenic component is characterized by completely combusted, mostly reworked wood ash with only rare remnants of charred material. Micromorphological and isotopic evidence indicates recrystallization of the wood ash. Large quantities of burnt bone, defined by a combination of microscopic and macroscopic criteria, and moderately heated soil lumps are closely associated with the woodash remains. The frequent presence of microscopic calcified rootlets indicates that the upper sequence formed in the vicinity of the former cave entrance. Burnt remains in the sediments are associated with systematic blade production and faunas that are dominated by the remains of fallow deer. Use-wear damage on blades and blade tools in conjunction with numerous cut marks on bones indicate an emphasis on butchering and prey-defleshing activities in the vicinity of fireplaces.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/25983758" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c7722e0f924cfb02f891e25314b0b06a" rel="nofollow" data-download="{"attachment_id":46334238,"asset_id":25983758,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46334238/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="49798248" href="https://haifa.academia.edu/RuthShahackGross">Ruth Shahack-Gross</a><script data-card-contents-for-user="49798248" type="text/json">{"id":49798248,"first_name":"Ruth","last_name":"Shahack-Gross","domain_name":"haifa","page_name":"RuthShahackGross","display_name":"Ruth Shahack-Gross","profile_url":"https://haifa.academia.edu/RuthShahackGross?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_25983758 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="25983758"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 25983758, container: ".js-paper-rank-work_25983758", });

The Paleolithic layers in this cave were studied using a suite of mineralogical and chemical techniques and a contextual sedimentological analysis (i.e., micromorphology). We show that the lower ca. 3 m of the stratigraphic sequence are dominated by clastic sediments deposited within a closed karstic environment. The deposits were formed by small-scale, concentrated mud slurries (infiltrated terra rosa soil) and debris flows. A few intervening lenses of mostly in situ burnt remains were also identified. The main part of the upper ca. 4.5 m consists of anthropogenic sediment with only moderate amounts of clastic geogenic inputs. The deposits are strongly cemented with calcite that precipitated from dripping water. The anthropogenic component is characterized by completely combusted, mostly reworked wood ash with only rare remnants of charred material. Micromorphological and isotopic evidence indicates recrystallization of the wood ash. Large quantities of burnt bone, defined by a combination of microscopic and macroscopic criteria, and moderately heated soil lumps are closely associated with the woodash remains. The frequent presence of microscopic calcified rootlets indicates that the upper sequence formed in the vicinity of the former cave entrance. Burnt remains in the sediments are associated with systematic blade production and faunas that are dominated by the remains of fallow deer. Use-wear damage on blades and blade tools in conjunction with numerous cut marks on bones indicate an emphasis on butchering and prey-defleshing activities in the vicinity of fireplaces.","downloadable_attachments":[{"id":46334238,"asset_id":25983758,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":49798248,"first_name":"Ruth","last_name":"Shahack-Gross","domain_name":"haifa","page_name":"RuthShahackGross","display_name":"Ruth Shahack-Gross","profile_url":"https://haifa.academia.edu/RuthShahackGross?f_ri=1703","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":130,"name":"Ancient History","url":"https://www.academia.edu/Documents/in/Ancient_History?f_ri=1703","nofollow":true},{"id":155,"name":"Evolutionary Biology","url":"https://www.academia.edu/Documents/in/Evolutionary_Biology?f_ri=1703","nofollow":true},{"id":392,"name":"Archaeology","url":"https://www.academia.edu/Documents/in/Archaeology?f_ri=1703","nofollow":true},{"id":417,"name":"Paleontology","url":"https://www.academia.edu/Documents/in/Paleontology?f_ri=1703","nofollow":true},{"id":767,"name":"Anthropology","url":"https://www.academia.edu/Documents/in/Anthropology?f_ri=1703"},{"id":772,"name":"Human Evolution","url":"https://www.academia.edu/Documents/in/Human_Evolution?f_ri=1703"},{"id":1703,"name":"Stable Isotope Analysis","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Analysis?f_ri=1703"},{"id":1706,"name":"Geoarchaeology","url":"https://www.academia.edu/Documents/in/Geoarchaeology?f_ri=1703"},{"id":7325,"name":"Archaeological Soil Micromorphology","url":"https://www.academia.edu/Documents/in/Archaeological_Soil_Micromorphology?f_ri=1703"},{"id":10867,"name":"Fire","url":"https://www.academia.edu/Documents/in/Fire?f_ri=1703"},{"id":13940,"name":"Fire Behaviour","url":"https://www.academia.edu/Documents/in/Fire_Behaviour?f_ri=1703"},{"id":34642,"name":"Israel","url":"https://www.academia.edu/Documents/in/Israel?f_ri=1703"},{"id":41720,"name":"Human","url":"https://www.academia.edu/Documents/in/Human?f_ri=1703"},{"id":48310,"name":"Cave","url":"https://www.academia.edu/Documents/in/Cave?f_ri=1703"},{"id":56754,"name":"Terroir","url":"https://www.academia.edu/Documents/in/Terroir?f_ri=1703"},{"id":64938,"name":"Fallow deer","url":"https://www.academia.edu/Documents/in/Fallow_deer?f_ri=1703"},{"id":78117,"name":"Carbon Isotopes","url":"https://www.academia.edu/Documents/in/Carbon_Isotopes?f_ri=1703"},{"id":112709,"name":"Debris Flow","url":"https://www.academia.edu/Documents/in/Debris_Flow?f_ri=1703"},{"id":121939,"name":"Technique","url":"https://www.academia.edu/Documents/in/Technique?f_ri=1703"},{"id":168891,"name":"Chemical Analysis","url":"https://www.academia.edu/Documents/in/Chemical_Analysis?f_ri=1703"},{"id":192294,"name":"Sediment","url":"https://www.academia.edu/Documents/in/Sediment?f_ri=1703"},{"id":202702,"name":"Form","url":"https://www.academia.edu/Documents/in/Form?f_ri=1703"},{"id":230701,"name":"Oxygen Isotopes","url":"https://www.academia.edu/Documents/in/Oxygen_Isotopes?f_ri=1703"},{"id":235690,"name":"Fires","url":"https://www.academia.edu/Documents/in/Fires?f_ri=1703"},{"id":1208706,"name":"Environment","url":"https://www.academia.edu/Documents/in/Environment?f_ri=1703"},{"id":1256666,"name":"Geologic Sediments","url":"https://www.academia.edu/Documents/in/Geologic_Sediments?f_ri=1703"},{"id":1451606,"name":"Wood Ash","url":"https://www.academia.edu/Documents/in/Wood_Ash?f_ri=1703"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_15753731" data-work_id="15753731" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/15753731/What_drove_sea_level_fluctuations_during_the_mid_Cretaceous_greenhouse_climate">What drove sea-level fluctuations during the mid-Cretaceous greenhouse climate?</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The major states, in which Earth's climate operates, i.e., icehouse, greenhouse and hothouse, are epochs of tens of millions of years.

These states set long-termboundary conditions that need to be considered for climate and sea level interpretations. This paper summarizes the conceptual models for hydrological cycling derived from the characteristics of these three climate states. While glacio-eustatic forcing of sea-level changes under icehouse climate conditions is fairly well understood, the drivers of eustatic sea-level fluctuations under greenhouse conditions remain enigmatic. This lack of understanding may be related to incoherencies in the current ideas about the impact of accelerated hydrological cycling on sea level under greenhouse climate conditions. <br />As an example for a greenhouse climate, we review evidences that link proxies for climate and sea level for the intensely studied, but controversially discussed, mid-Cretaceous  sea-level history. Based on sequence stratigraphy and a recently published high-precision timescale, we demonstrate that the late Middle Turonian Pewsey δ13C isotope maximum represents a major transgression, not a regression as previously stated, which conflicts with the interpretation of a co-occurring δ18O maximum to reflect a short glacial episode. This contradiction can be solved by the concept, presented here, that dominance of aquifer-eustasy characterized sea-level forcing during the Turonian greenhouse climate, despite a possible, though contentious, sporadic presence of minor ice sheets. The effects of temperature and ice volume both lead to a pronounced δ18Ocarb maximum during glacio-eustatic regressions. In contrast, the opposing effects of temperature and groundwater volume on oxygen-isotope fractionation lead to a δ18Ocarb maximum during aquifer-eustatic transgressions. We suggest that, throughout Earth history, both aquifer-eustatic and glacio-eustatic forcing formed a combined sea-level response, with dominance of aquifer-eustasy being typical for the greenhouse climate mode. During the icehouse mode, aquifer-eustasy apparently remains active as a background process, but is outpaced by the glacio-eustatic effect.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/15753731" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="2e0fbec2f023450e30bc5c4719af06a3" rel="nofollow" data-download="{"attachment_id":40718981,"asset_id":15753731,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/40718981/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="915418" href="https://uni-bremen.academia.edu/InesWendler">Ines Wendler</a><script data-card-contents-for-user="915418" type="text/json">{"id":915418,"first_name":"Ines","last_name":"Wendler","domain_name":"uni-bremen","page_name":"InesWendler","display_name":"Ines Wendler","profile_url":"https://uni-bremen.academia.edu/InesWendler?f_ri=1703","photo":"https://0.academia-photos.com/915418/405410/496051/s65_ines.wendler.jpg"}</script></span></span></li><li class="js-paper-rank-work_15753731 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="15753731"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 15753731, container: ".js-paper-rank-work_15753731", });

Over this same period, wild populations of the microendemic axolotl salamander (Ambystoma mexicanum) have been dramatically reduced, and it currently persists in isolated areas of this aquatic system, which is situated at the edge of Mexico City. In this study, we examine potential trophic interactions and niche overlap among two exotic fishes: carp and tilapia, and the native axolotl. Axolotl had more diverse diets and a higher trophic position compared to the exotics. Stable isotope analysis revealed substantial trophic niche overlap among axolotl and the exotics. The two exotics occupied a larger niche area than the axolotl, suggesting higher levels of omnivory and diet specialization. Current exotic fish removal efforts will further our understanding of interactions between the axolotl and exotic species, and are expected to benefit axolotl recovery efforts.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/8519498" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="f37e54d2899756b60ffd6455f0992ac6" rel="nofollow" data-download="{"attachment_id":48070604,"asset_id":8519498,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48070604/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="17468714" href="https://independent.academia.edu/ElsaValiente">Elsa Valiente</a><script data-card-contents-for-user="17468714" type="text/json">{"id":17468714,"first_name":"Elsa","last_name":"Valiente","domain_name":"independent","page_name":"ElsaValiente","display_name":"Elsa Valiente","profile_url":"https://independent.academia.edu/ElsaValiente?f_ri=1703","photo":"https://0.academia-photos.com/17468714/4856461/5587553/s65_elsa.valiente.jpg_oh_0ca8efff44b70d4ae26851dd90b273de_oe_54bfbdf8___gda___1422033780_55f16995c7d0b1497005cfe8f7d3c48f"}</script></span></span></li><li class="js-paper-rank-work_8519498 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="8519498"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 8519498, container: ".js-paper-rank-work_8519498", });

Fossil shells were recovered from the archaeological excavations of Grotta della Serratura and recent specimens collected adjacent to the cave. The record is discontinuous and spans from ca 14 to 7 ka cal BP. The oxygen isotope composition of the fossil shells suggests they were grown from environmental waters (e.g. precipitation) isotopically similar to the present during the recorded part of the Late Glacial. A notable exception is represented by a layer at ca 13.4 ka cal BP, with shells characterised by 18 O-enriched values, suggesting drier conditions, with rainfall perhaps reduced by 25% compared to the present day. This layer could correspond in part with the GI-1b event of the Greenland ice-core records. The onset of the Holocene was marked by a decrease of δ 18 O, suggesting an increase in humidity. Significantly lower δ 18 O values occur at ca 7.4 ka cal BP, in agreement with other stable isotope records, which suggests enhanced rainfall over the Mediterranean region at that time.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/10384833" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="6dd1e541947728dea5c62e18a1a4fb10" rel="nofollow" data-download="{"attachment_id":47418932,"asset_id":10384833,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/47418932/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="25540469" href="https://unifi.academia.edu/fabiomartini">fabio martini</a><script data-card-contents-for-user="25540469" type="text/json">{"id":25540469,"first_name":"fabio","last_name":"martini","domain_name":"unifi","page_name":"fabiomartini","display_name":"fabio martini","profile_url":"https://unifi.academia.edu/fabiomartini?f_ri=1703","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_10384833 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="10384833"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 10384833, container: ".js-paper-rank-work_10384833", });

This paper presents a pilot study of strontium (Sr) isotope ratios from Iron Age horse tooth enamel samples.

Furthermore, previous radiocarbon ( ¹⁴ C) analyses have only been able to date him broadly to the 3rd–4th century BC. In this study, stable isotope measurements (δ ¹³ C, δ ¹⁵ N) on bone collagen from Tollund Man’s femur and rib showed that the diet of Tollund Man was terrestrial-based and that the crops he ate probably were grown on manured fields. Accelerator mass spectrometry (AMS) ¹⁴ C dates were obtained on both the <30kDa and >30kDa fractions of ultrafiltered collagen. Results showed that the ultrafiltration removed contamination from older substances from the burial environment. The femur was dated to 2330±23 BP, the rib to 2322±30 BP. These dates statistically agree with a previously published AMS ¹⁴ C age on skin. By combining the new dates with the previous date of his skin it was possible to narrow down the age of Tollund Man to the period 405–380 cal BC (95.4% confidence interval).</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/38123816" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c358bc8149c808907a7b23c4638be82d" rel="nofollow" data-download="{"attachment_id":59137567,"asset_id":38123816,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/59137567/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="68152" href="https://museumsilkeborg.academia.edu/NinaHeltNielsen">Nina Helt Nielsen</a><script data-card-contents-for-user="68152" type="text/json">{"id":68152,"first_name":"Nina Helt","last_name":"Nielsen","domain_name":"museumsilkeborg","page_name":"NinaHeltNielsen","display_name":"Nina Helt Nielsen","profile_url":"https://museumsilkeborg.academia.edu/NinaHeltNielsen?f_ri=1703","photo":"https://0.academia-photos.com/68152/84437/12380754/s65_nina_helt.nielsen.jpg"}</script></span></span></li><li class="js-paper-rank-work_38123816 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="38123816"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 38123816, container: ".js-paper-rank-work_38123816", });

Osteological analysis provides the first conclusive proof for the occurrence of dismemberment of the dead at Irish passage tombs, practised contemporarily with cremation as one of a suite of funerary treatments. The research also highlights changes in burial tradition at the complex over the course of the Neolithic. Providing a chronology for these changes allows them to be linked to wider trends in monument construction, which may relate to changes in both land use and climate during the period. Multi-isotope analysis hints at the presence of non-local individuals among the interred and the possible existence of different food sourcing areas at the onset of the later Neolithic period.

Osteological analysis provides the first conclusive proof for the occurrence of dismemberment of the dead at Irish passage tombs, practised contemporarily with cremation as one of a suite of funerary treatments. The research also highlights changes in burial tradition at the complex over the course of the Neolithic. Providing a chronology for these changes allows them to be linked to wider trends in monument construction, which may relate to changes in both land use and climate during the period. Multi-isotope analysis hints at the presence of non-local individuals among the interred and the possible existence of different food sourcing areas at the onset of the later Neolithic period.

At present, it is unclear when hominins started to habitually consume marine resources. This study examines shellfish exploitation from a behavioural ecology perspective, addressing how and when past hunter-gatherers from the Levant used coastal resources for subsistence purposes. We investigate the seasonality of shellfish exploitation in the Levantine Upper Palaeolithic through oxygen isotope analysis on shells of the intertidal rocky shore mollusc Phorcus (Osilinus) turbinatus from the key site Ksâr 'Akil (Lebanon). At this rockshelter, multi-layered archaeological deposits contained remains of both marine and terrestrial molluscs in relatively large quantities, which were consumed and used as tools and ornaments by the occupants of the site. Our results indicate that at the start of the Initial Upper Palaeolithic (IUP), there is no evidence for shellfish consumption. Humans started to take fresh shellfish to the rockshelter from the second half of the IUP onward, albeit in low quantities. During the Early Upper Palaeolithic (EUP) shellfish exploitation became increasingly frequent. Oxygen isotope data show that shellfish exploitation was practised in every season throughout most of the Upper Palaeolithic (UP), with an emphasis on the colder months. This suggests that coastal resources had a central role in early UP foraging strategies, rather than a seasonally restricted supplementary one. Year-round shellfish gathering, in turn, suggests that humans occupied the rockshelter at different times of the year, although not necessarily continuously. Our oxygen isotope data is complemented with broader-scale exploitation patterns of faunal resources, both vertebrate and invertebrate, at the site. The inclusion of coastal marine resources signifies a diversification of the human diet from the EUP onward, which is also observed in foraging practices linked to the exploitation of terrestrial fauna.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/34873499" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="bf212858e44d35ce4e6c240f8e42856a" rel="nofollow" data-download="{"attachment_id":54732796,"asset_id":34873499,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/54732796/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="21297152" href="https://oeaw.academia.edu/MarjoleinBosch">Marjolein Bosch</a><script data-card-contents-for-user="21297152" type="text/json">{"id":21297152,"first_name":"Marjolein","last_name":"Bosch","domain_name":"oeaw","page_name":"MarjoleinBosch","display_name":"Marjolein Bosch","profile_url":"https://oeaw.academia.edu/MarjoleinBosch?f_ri=1703","photo":"https://0.academia-photos.com/21297152/5896583/6695908/s65_marjolein.bosch.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-34873499">+1</span><div class="hidden js-additional-users-34873499"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://unimelb.academia.edu/AmyPrendergast">Amy L Prendergast</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-34873499'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-34873499').html();

Sildenafil, along with Tadalafil and Vardenafil belong to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.<br />Since its first production in 1998, Viagra® has generated well in excess of $10 billion US dollars in sales and with Pfizers’ patent extended to April 2020 (3) it still remains the only sildenafil-based treatment option for sufferers of ED in the US. There are no legal ‘generic-Viagra’ formulations available in the US.

Viagra® contains the active pharmaceutical ingredient (API) sildenafil, as the citrate salt. Sildenafil, along with Tadalafil and Vardenafil belong to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.\nSince its first production in 1998, Viagra® has generated well in excess of $10 billion US dollars in sales and with Pfizers’ patent extended to April 2020 (3) it still remains the only sildenafil-based treatment option for sufferers of ED in the US. There are no legal ‘generic-Viagra’ formulations available in the US. However, formulations containing sildenafil citrate as API are widely available over the internet and often sold as ‘generic\nViagra’. These cheaper alternatives are often manufactured under less than ideal conditions with little or no QA/QC procedures in place.\nThe World Health Organisation recognised the scale of the problem in its 2010 bulletin “Growing threat from counterfeit medicines” (4) and quotes a Dutch study cited in the International Journal of Clinical Practice in which from a cohort of 370 seized Viagra® samples, only 10 were genuine.\nWe sourced a variety of tablets sold for the treatment of ED which claimed to have sildenafil citrate as API.

It is puzzling how an ice dependent species could breed in the Baltic Sea during the Holocene Thermal Maximum (HTM), and it remains unclear for how long harp seals bred in the Baltic Sea and when the population became extirpated. We combined radiocarbon dating of harp seal bones with zooarchaeological, palaeoenvironmental and stable isotope data to reconstruct the harp seal occurrence in the Baltic Sea. Our study revealed two phases of harp seal presence and verifies that the first colonization and establishment of a local breeding population occurred within the HTM. We suggest that periods with very warm summers but cold winters allowed harp seals to breed on the ice. Human pressure, salinity fluctuations with consequent changes in prey availability and competition for food resources, mainly cod, resulted in physiological stress that ultimately led to a population decline and local extirpation during the first phase. The population reappeared after a long hiatus. Final extinction of the Baltic Sea harp seal coincided with the Medieval Warm Period. Our data provide insights for the first time on the combined effects of past climatic and environmental change and human pressure on seal populations and can contribute with new knowledge on ongoing discussions concerning the impacts of such effects on current arctic seal populations.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/44659211" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="aec57676950b822460c43e0e165e3d63" rel="nofollow" data-download="{"attachment_id":65131233,"asset_id":44659211,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/65131233/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="676733" href="https://leiza.academia.edu/UlrichSchm%C3%B6lcke">Ulrich Schmölcke</a><script data-card-contents-for-user="676733" type="text/json">{"id":676733,"first_name":"Ulrich","last_name":"Schmölcke","domain_name":"leiza","page_name":"UlrichSchmölcke","display_name":"Ulrich Schmölcke","profile_url":"https://leiza.academia.edu/UlrichSchm%C3%B6lcke?f_ri=1703","photo":"https://0.academia-photos.com/676733/2704679/3148770/s65_ulrich.schm_lcke.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-44659211">+2</span><div class="hidden js-additional-users-44659211"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://su-se.academia.edu/AikateriniGlykou">Aikaterini Glykou</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://vu-lt.academia.edu/giedrepiliciauskiene">giedre piliciauskiene</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-44659211'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-44659211').html();

Our data provide insights for the first time on the combined effects of past climatic and environmental change and human pressure on seal populations and can contribute with new knowledge on ongoing discussions concerning the impacts of such effects on current arctic seal populations.","downloadable_attachments":[{"id":65131233,"asset_id":44659211,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":676733,"first_name":"Ulrich","last_name":"Schmölcke","domain_name":"leiza","page_name":"UlrichSchmölcke","display_name":"Ulrich Schmölcke","profile_url":"https://leiza.academia.edu/UlrichSchm%C3%B6lcke?f_ri=1703","photo":"https://0.academia-photos.com/676733/2704679/3148770/s65_ulrich.schm_lcke.jpg"},{"id":2763306,"first_name":"Aikaterini","last_name":"Glykou","domain_name":"su-se","page_name":"AikateriniGlykou","display_name":"Aikaterini Glykou","profile_url":"https://su-se.academia.edu/AikateriniGlykou?f_ri=1703","photo":"https://0.academia-photos.com/2763306/2910474/3401300/s65_aikaterini.glykou.jpg"},{"id":3598725,"first_name":"giedre","last_name":"piliciauskiene","domain_name":"vu-lt","page_name":"giedrepiliciauskiene","display_name":"giedre piliciauskiene","profile_url":"https://vu-lt.academia.edu/giedrepiliciauskiene?f_ri=1703","photo":"https://0.academia-photos.com/3598725/140988423/130478278/s65_giedre.piliciauskiene.png"}],"research_interests":[{"id":158,"name":"Marine Biology","url":"https://www.academia.edu/Documents/in/Marine_Biology?f_ri=1703","nofollow":true},{"id":1703,"name":"Stable Isotope Analysis","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Analysis?f_ri=1703","nofollow":true},{"id":4997,"name":"Mesolithic Archaeology","url":"https://www.academia.edu/Documents/in/Mesolithic_Archaeology?f_ri=1703","nofollow":true},{"id":6972,"name":"Baltic Sea Region Studies","url":"https://www.academia.edu/Documents/in/Baltic_Sea_Region_Studies?f_ri=1703","nofollow":true},{"id":13797,"name":"Marine Mammals","url":"https://www.academia.edu/Documents/in/Marine_Mammals?f_ri=1703"},{"id":17472,"name":"Palaeoecology","url":"https://www.academia.edu/Documents/in/Palaeoecology?f_ri=1703"},{"id":17635,"name":"Marine biodiversity","url":"https://www.academia.edu/Documents/in/Marine_biodiversity?f_ri=1703"},{"id":26086,"name":"Neolithic Europe","url":"https://www.academia.edu/Documents/in/Neolithic_Europe?f_ri=1703"},{"id":26089,"name":"Mesolithic Europe","url":"https://www.academia.edu/Documents/in/Mesolithic_Europe?f_ri=1703"},{"id":50074,"name":"Ancient Seals and Sealings","url":"https://www.academia.edu/Documents/in/Ancient_Seals_and_Sealings?f_ri=1703"},{"id":66662,"name":"Baltic archaeology","url":"https://www.academia.edu/Documents/in/Baltic_archaeology?f_ri=1703"},{"id":78965,"name":"Holocene","url":"https://www.academia.edu/Documents/in/Holocene?f_ri=1703"},{"id":592100,"name":"History of the Baltic Sea Region","url":"https://www.academia.edu/Documents/in/History_of_the_Baltic_Sea_Region?f_ri=1703"},{"id":982396,"name":"Stable Isotope Applied to Paleoclimate and Paleoenvironment","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Applied_to_Paleoclimate_and_Paleoenvironment?f_ri=1703"},{"id":2933345,"name":"Holocene Thermal Maximum","url":"https://www.academia.edu/Documents/in/Holocene_Thermal_Maximum?f_ri=1703"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_45103556 coauthored" data-work_id="45103556" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/45103556/Strontium_87Sr_86Sr_isotope_analysis_of_the_Namu_skeletal_assemblage_A_study_of_past_human_migration_on_Taumako_a_Polynesian_Outlier_in_the_eastern_Solomon_Islands">Strontium (87Sr/86Sr) isotope analysis of the Namu skeletal assemblage: A study of past human migration on Taumako, a Polynesian Outlier in the eastern Solomon Islands</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Objectives: This study aims to assess if inter-island mobility can be identified during the Namu period (ca. 1,510-1800 AD) using 87Sr/86Sr analysis of dental enamel for individuals from the Namu burial ground on Taumako Island in the... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_45103556" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">Objectives: This study aims to assess if inter-island mobility can be identified during the Namu period (ca. 1,510-1800 AD) using 87Sr/86Sr analysis of dental enamel for individuals from the Namu burial ground on Taumako Island in the eastern Solomon Island Chain. Historic evidence from this region suggests that females migrated between the Duff, Reef, and Santa Cruz islands for marriage purposes. We hypothesize that observable trends in migrational (87Sr/86Sr ) and dietary (δ13C and δ15N) isotopes can reveal the relationship between demographic factors, social status, diet, and female mobility on Taumako. Methods: This research analyzes enamel 87Sr/86Sr  for 58 individuals in the Namu skeletal sample. The 87Sr/86Sr results were compared with published dietary isotope data (bone collagen and dentin δ13C and δ15N values) and type/number of grave goods to assess whether trends within the data may be related to sex, age, or burial wealth. Results: The results show that females display significantly higher 87Sr/86Sr  values compared to males. One young adult female displayed a 87Sr/86Sr  value that was +2SD outside the mean for the sampled individuals. A linear mixed-effects model and principle components analysis of 87Sr/86Sr, δ13C, and δ15N values suggest that wealth, sex, and age-cohort membership have an observable influence on the isotopic variation for the Taumako population. Conclusion: We suggest that during the Namu period, Taumako was patrilocal and that some females migrated there from the nearby Santa Cruz and Reef islands. One female immigrated to Taumako from a geologically distinct region outside of the Duff, Reef, and Santa Cruz Island groups. <br /><br />KEYWORDS: bioarchaeology, biogeochemistry, isotope analysis, migration, Polynesian Outlier, Solomon Islands</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/45103556" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="9390fc9f8aa3e8ff4b5a0a03314acd19" rel="nofollow" data-download="{"attachment_id":65667930,"asset_id":45103556,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/65667930/download_file?st=MTc0MDUzMTczNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="5702096" href="https://otago.academia.edu/RTKramer">Robyn T Kramer</a><script data-card-contents-for-user="5702096" type="text/json">{"id":5702096,"first_name":"Robyn","last_name":"Kramer","domain_name":"otago","page_name":"RTKramer","display_name":"Robyn T Kramer","profile_url":"https://otago.academia.edu/RTKramer?f_ri=1703","photo":"https://0.academia-photos.com/5702096/2473641/72414688/s65_robyn.kramer.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-45103556">+1</span><div class="hidden js-additional-users-45103556"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://otago.academia.edu/CharlotteKing">Charlotte King</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-45103556'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-45103556').html();

The double spike is added prior to chemical purification, so that laboratory and instrumental mass fractionations are separated from natural mass-dependent fractionation. Fractionation is determined on four Mo mass ratios, providing an internal consistency check. The external standard reproducibility is at 0.06 per mil on the 98 Mo/ 95 Mo ratio (2 standard deviation)). Using a normal microconcentric nebuliser with a cyclonic spray chamber, the minimum quantity of Mo is $1 mg for high-precision results. A hydrothermal molybdenite shows fractionation of À0.3 per mil on the 98 Mo/ 95 Mo ratio relative to our standard (Johnson Matthey, 1000 mg/mL (0.3%) ICP standard solution, lot 602332B). Fine-grained sediments show fractionation of 0.1 and À0.3 per mil on the 98 Mo/ 95 Mo ratio.

The double spike is added prior to chemical purification, so that laboratory and instrumental mass fractionations are separated from natural mass-dependent fractionation. Fractionation is determined on four Mo mass ratios, providing an internal consistency check. The external standard reproducibility is at 0.06 per mil on the 98 Mo/ 95 Mo ratio (2 standard deviation)). Using a normal microconcentric nebuliser with a cyclonic spray chamber, the minimum quantity of Mo is $1 mg for high-precision results. A hydrothermal molybdenite shows fractionation of À0.3 per mil on the 98 Mo/ 95 Mo ratio relative to our standard (Johnson Matthey, 1000 mg/mL (0.3%) ICP standard solution, lot 602332B). Fine-grained sediments show fractionation of 0.1 and À0.3 per mil on the 98 Mo/ 95 Mo ratio. The observed Mo isotope fractionation is small but resolvable with the presented high-resolution technique. , 2001.

We integrate 2500 years of stable isotope (δ34S, δ13C, and δ15N) and zooarchaeological evidence from Gulf of Mexico fisheries to assess cultural, demographic, and technological changes affecting sheepshead (Archosargus probatocephalus) populations and fishing practices in Louisiana, USA. Concurrent with human population growth, average sizes of sheepshead caught decreased from the 1720s to 1830s. The size of fish caught after the 1830s increased to pre-1720 levels at the same time that isotopic compositions of fish bone collagen show that fish were being caught from a more diverse range of ecosystems, including distant seagrass beds.

We integrate 2500 years of stable isotope (δ34S, δ13C, and δ15N) and zooarchaeological evidence from Gulf of Mexico fisheries to assess cultural, demographic, and technological changes affecting sheepshead (Archosargus probatocephalus) populations and fishing practices in Louisiana, USA. Concurrent with human population growth, average sizes of sheepshead caught decreased from the 1720s to 1830s. The size of fish caught after the 1830s increased to pre-1720 levels at the same time that isotopic compositions of fish bone collagen show that fish were being caught from a more diverse range of ecosystems, including distant seagrass beds. Our findings provide the first evidence for large-scale depressions of historical sheepshead populations and the
