The male reproductive tract of P. magdalenae is composed of testes, efferent ducts, epididymides, deferent ducts, seminal vesicles, Leydig, alkaline, and clasper glands, and claspers, all of which are paired and functional. Four sexual maturity stages were established: immature, maturing, reproductively active, and resting. The degree of claspers calcification is also a good indicator of sexual maturity in this species. The testes are lobulated, each lobe contains numerous spermatocysts which are organized in zones and are displaced radially from germinal papillae to the spermatozoa zone where individual spermatozoa are conveyed to the efferent ducts. The epididymis can be regionalized in head, body, and tail; these regions are distinguished by external pigmentation and by the epithelium lining configuration. The tail of the epididymis is connected with the deferent duct and this, in turn, with the seminal vesicle. The spermatozoa are organized in spermatozeugmata which begin to form in the deferent duct; this latter organ is attached laterally at the Leydig gland that is composed by simple glandular units. Irregular and vesicular secretions can be found in the genital ducts. These secretions might be associated with the maturation of the spermatozoa and formation of spermatozeugmata. The male reproductive tract of P. magdalenae is similar to other elasmobranchs; however, two types of primary spermatogonia, an epididymis internally regionalized, and the presence and structure of spermatozeugmata are specific features not yet described in freshwater stingrays. Most of the year, the males were reproductively active, however, few resting adult males occurred during one of the months of the lowest waters. J.

Geobatrachus walkeri is a frog that belongs to a monotypic genus and is endemic to the Sierra Nevada de Santa Marta, Colombia. The species inhabits different microhabitats between 2 000 to 3 500m altitude, including the leaf litter of a pine plantation. To understand its reproductive ecology, we conducted eight frog samplings, covering the rainy and dry seasons, and two habitat types (secondary native forest and pine plantation) during 2010-2011. For this study, we also included data obtained from five previous similar samplings undertaken during 2008-2009. The pine leaf litter was the main microhabitat where frogs were found; we heard choruses of six-ten calling males during all sampled months, and observed the frogs having diurnal and nocturnal activity. Regardless of the year of study, the population consisted of neonates recruited several times of the year, a large number of juveniles with a wide range of body sizes, and fewer adults with a narrower range of body size. The histological analyses of the gonads showed that the size at maturity was near 18mm SVL for males and females, and those adult males and females were reproductive active during all sampling months, suggesting a continuous reproductive activity pattern. However, during the dry season, the seminiferous tubules showed a drastically diminished spermatic epithelium although containing abundant luminal spermatozoa, which suggest a reduction in the sperm production at the end of this season.

We quantified the net uptake of nutrients during gestation in an Andean population of Mabuya and compared these results with other matrotrophic skinks and eutherian mammals. Total dry and wet masses, ash and organic content, ions (calcium, potassium, sodium, magnesium, iron), lipids (cholesterol, vitamin E and fatty acids in the major lipid classes-triacylglycerol, phospholipids, cholesteryl ester, free fatty acids), nitrogen (an index of protein) were measured during the different developmental stages throughout gestation, and in neonates. A significant net uptake of inorganic and organic matter was found. This uptake begins slowly during early gestation but accelerates during the last third of gestation when the growth of the embryo is maximal and the allantoplacenta has developed its greatest complexity. The drastic reduction of egg size in this clade is related to the great reduction in the contribution of lecithotrophic nutrients to the embryo, an obligatory placentotrophy from early developmental stages, and the highest placental complexity known in the Reptilia. All of these features converge with features found in eutherian mammals.","publication_date":{"day":1,"month":1,"year":2011,"errors":{}},"publication_name":"Journal of Comparative

Recent developmental studies have provided a basis for understanding lizard autopodial element homology based on developmental and comparative anatomy. In addition, the composition and identity of some carpal and tarsal elements of lizard limbs, and reptiles in general, have been the theme of discussions about their homology compared to non-squamate Lepidosauromorpha and basal Amniota. The study of additional embryonic material from different lizard families may improve our understanding of squamate limb evolution. Here, we analyze limb morphogenesis in the gekkonid lizard Gonatodes albogularis describing patterns of chondrogenesis and ossification from early stages of embryonic development to hatchlings. Our results are in general agreement with previous developmental studies, but we also show that limb development in squamates probably involves more chondrogenic elements for carpal and tarsal morphogenesis, as previously recognized on the grounds of comparative anatomy. We provide evidence for the transitory presence of distal carpale 1 and intermedium in the carpus and tibiale, intermedium, distal centralia, and distal tarsale 2 in the tarsus. Hence, we demonstrate that some elements that were believed to be lost in squamate evolution are conserved as transitory elements during limb development. However, these elements do not represent just phylogenetic burden but may be important for the morphogenesis of the lizard autopodium. J.

The oocyte of the primary follicle is surrounded by a single layer of follicle cells. During the previtellogenic stages, these cells become stratified and differentiated in three cell types: small, intermediate, and large globoid, non pyriform cells. Fluid-filled spaces arise among follicular cells in late previtellogenic follicles and provide evidence of cell lysis. In vitellogenic follicles, the follicular cells constitute a monolayered granulosa with large lacunar spaces; the content of their cytoplasm is released to the perivitelline space where the zona pellucida is formed. The oolemma of younger oocytes presents incipient short projections; as the oocyte grows, these projections become organized in a microvillar surface. During vitellogenesis, cannaliculi develop from the base of the microvilli and internalize materials by endocytosis. In the juxtanuclear ooplasm of early previtellogenic follicles, the Balbiani's vitelline body is found as an aggregate of organelles and lipid droplets; this complex of organelles disperses in the ooplasm during oocyte growth. In late previtellogenesis, membranous organelles are especially abundant in the peripheral ooplasm, whereas abundant vesicles and granular material occur in the medullar ooplasm. The ooplasm of vitellogenic follicles shows a peripheral band constituted by abundant membranous organelles and numerous vesicular bodies, some of them with a small lipoprotein core. No organized yolk platelets, like in lecithotrophic reptiles, were observed. Toward the medullary ooplasm, electron-lucent vesicles become larger in size containing remains of cytoplasmic material in dissolution. The results of this study demonstrate structural similarities between the follicles of this species and other Squamata; however, the ooplasm of the mature oocyte of Mabuya is morphologically similar to the ooplasm of mature oocytes of marsupials, suggesting an interesting evolutionary convergence related to the evolution of placentotrophy and of microlecithal eggs.

these prey were the most important in terms of volume and number. there were no significant differences in the number, type and abundance of prey, as well as in the length and volume of the consumed prey between males and females. there were significant differences between the diet of adults and juveniles. lizards ate prey with similar volumes and lengths throughout the year independent of the rainfall regime. also, there were no significant differences in prey volume and length with regard to the reproductive stages of females and males. the lack of variation in diet in this population suggests a constant availability of prey in the study area. When we compared diet composition of this population with that of other species of Mabuya, we found that diet tends to be similar among the different species and populations of Mabuya in south america. adult lizards showed two activity peaks during the day, before and after midday; this pattern of daily activity was constant throughout the year. Preferred microhabitats used by this population are related to anthropogenic disturbance. the population of the present study seems to have quite wide ecological requirements (generalist diet, use of a wide spectrum of microhabitats and extended daily activity), which allows it to exploit disturbed habitats.","publication_date":{"day":null,"month":null,"year":2010,"errors":{}},"publication_name":"South American Journal of Herpetology","grobid_abstract_attachment_id":49979566},"translated_abstract":null,"internal_url":"https://www.academia.edu/4224756/Diet_Microhabitat_use_and_Daily_Activity_Patterns_of_an_Andean_Population_of_Mabuya_Squamata_Scincidae","translated_internal_url":"","created_at":"2013-08-12T09:16:19.917-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":1211170,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":49979566,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/49979566/thumbnails/1.jpg","file_name":"Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6.pdf","download_url":"https://www.academia.edu/attachments/49979566/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diet_Microhabitat_use_and_Daily_Activity.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/49979566/Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6-libre.pdf?1477829758=\u0026response-content-disposition=attachment%3B+filename%3DDiet_Microhabitat_use_and_Daily_Activity.pdf\u0026Expires=1732391934\u0026Signature=CceTMOTuSTGMoKHhOcDlRj5hNeEv3c9I8ZZt-zelDmtBvA6lzGWg-LRFE~MrdnSUk5wUn15CIC0J05ElKznW1evnlP7iGGd8yPjrxGbCoucEnlXlb-52T581Vu1gUWmYboQvRAblzAuPbs9rQCImeogA4iZhWG~09mY2lG37EYy2k4m2oQBVSBioM0PnBr9Qvxjm2Q7L8tG8yO9x0NqEH52b7jGkHWMBdOe26Nsnch3e3DUn33TGM6LKl88siou9lA5AhbTUYs09yk1STvE7hPy6gWYggs0qSHu7WHW7cHOuMsMl424AnsrJnS3bMblzIQWAHDul9-dZpgeu25VxsA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Diet_Microhabitat_use_and_Daily_Activity_Patterns_of_an_Andean_Population_of_Mabuya_Squamata_Scincidae","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":1211170,"first_name":"Martha Patricia","middle_initials":null,"last_name":"Ramirez-Pinilla","page_name":"MartaRamirez","domain_name":"uis","created_at":"2012-02-15T05:24:58.208-08:00","display_name":"Martha Patricia Ramirez-Pinilla","url":"https://uis.academia.edu/MartaRamirez"},"attachments":[{"id":49979566,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/49979566/thumbnails/1.jpg","file_name":"Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6.pdf","download_url":"https://www.academia.edu/attachments/49979566/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diet_Microhabitat_use_and_Daily_Activity.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/49979566/Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6-libre.pdf?1477829758=\u0026response-content-disposition=attachment%3B+filename%3DDiet_Microhabitat_use_and_Daily_Activity.pdf\u0026Expires=1732391934\u0026Signature=CceTMOTuSTGMoKHhOcDlRj5hNeEv3c9I8ZZt-zelDmtBvA6lzGWg-LRFE~MrdnSUk5wUn15CIC0J05ElKznW1evnlP7iGGd8yPjrxGbCoucEnlXlb-52T581Vu1gUWmYboQvRAblzAuPbs9rQCImeogA4iZhWG~09mY2lG37EYy2k4m2oQBVSBioM0PnBr9Qvxjm2Q7L8tG8yO9x0NqEH52b7jGkHWMBdOe26Nsnch3e3DUn33TGM6LKl88siou9lA5AhbTUYs09yk1STvE7hPy6gWYggs0qSHu7WHW7cHOuMsMl424AnsrJnS3bMblzIQWAHDul9-dZpgeu25VxsA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":173,"name":"Zoology","url":"https://www.academia.edu/Documents/in/Zoology"},{"id":441325,"name":"South American","url":"https://www.academia.edu/Documents/in/South_American"},{"id":843856,"name":"Ecological Applications","url":"https://www.academia.edu/Documents/in/Ecological_Applications"}],"urls":[{"id":1446827,"url":"http://www.bioone.org/doi/abs/10.2994/057.005.0107"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="2324354"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/2324354/Microhabitats_for_oviposition_and_male_clutch_attendance_in_Hyalinobatrachium_aureoguttatum_Anura_Centrolenidae_Copeia_2012_4_722_731_2012"><img alt="Research paper thumbnail of Microhabitats for oviposition and male clutch attendance in Hyalinobatrachium aureoguttatum (Anura: Centrolenidae).

The mental gland is an oval shaped pad which develops exclusively in reproductive males. It is composed of 255 to 710 simple glands of merocrine secretion arranged in a dorso-ventral disposition. The outlets of the glands are spindle-shaped or fusiform. Negative stain reaction for AB and PAS is consistent with results of the glandular components of mental glands from other Plethodontidae. Males of this species produce sperm continuously throughout the year: all examined adult males showed conspicuous mental glands. However, an evident and significant increase in the surface area of the mental gland pad, in the density of the glands, and in the number of tubular glands was observed in the males collected during the breeding season. At the histological level, a slight variation was observed among males in the height and diameter of the simple tubular glands, and significant variation was found in the diameter of the secretory granules. This variation may reflect the fact that, although males potentially can mate during all months of the year, females oviposit seasonally. During this defined season, the hypertrophy of the mental gland is the greatest.","publication_date":{"day":null,"month":null,"year":2009,"errors":{}},"publication_name":"Amphibia-reptilia","grobid_abstract_attachment_id":49979570},"translated_abstract":null,"internal_url":"https://www.academia.edu/4224757/The_mental_gland_of_Bolitoglossa_nicefori_Caudata_Plethodontidae","translated_internal_url":"","created_at":"2013-08-12T09:16:23.915-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":1211170,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":49979570,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/49979570/thumbnails/1.jpg","file_name":"The_mental_gland_of_Bolitoglossa_nicefor20161030-3510-sdytku.pdf","download_url":"https://www.academia.edu/attachments/49979570/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_mental_gland_of_Bolitoglossa_nicefor.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/49979570/The_mental_gland_of_Bolitoglossa_nicefor20161030-3510-sdytku-libre.pdf?1477829751=\u0026response-content-disposition=attachment%3B+filename%3DThe_mental_gland_of_Bolitoglossa_nicefor.pdf\u0026Expires=1732391934\u0026Signature=eNAISb-OtqOTN4XgZSGXul5VNPiCCBazEDu6zL2z0NSna~zlsUjGjRJ3QVDP7FMT6f8q6j~dVAbXrRaNUrRGYdIqXg4FWbZK-MljTy~JC1VcxME8sJsMuOnvt2li3UgY1bPJ0go7j3U525X~QFjn7tpn36xtR7DucttUI34YbfMePQ8G-eYjBu11UN9bar57Sn8DhF6eoRPQHe1EgNQ2IxvvPV~WiffG4SErIhZlJlp4~XWSQTWabD~6AntXZlA5Hj5N0SHB9SX4HFqZdljTohLIyLLlrevXtGzww9uAWFulAOWAN0~nMeW98GtquQt43YbGU6IJdOpCox2slmo-Ug__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"The_mental_gland_of_Bolitoglossa_nicefori_Caudata_Plethodontidae","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":1211170,"first_name":"Martha Patricia","middle_initials":null,"last_name":"Ramirez-Pinilla","page_name":"MartaRamirez","domain_name":"uis","created_at":"2012-02-15T05:24:58.208-08:00","display_name":"Martha Patricia Ramirez-Pinilla","url":"https://uis.academia.edu/MartaRamirez"},"attachments":[{"id":49979570,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/49979570/thumbnails/1.jpg","file_name":"The_mental_gland_of_Bolitoglossa_nicefor20161030-3510-sdytku.pdf","download_url":"https://www.academia.edu/attachments/49979570/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_mental_gland_of_Bolitoglossa_nicefor.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/49979570/The_mental_gland_of_Bolitoglossa_nicefor20161030-3510-sdytku-libre.pdf?1477829751=\u0026response-content-disposition=attachment%3B+filename%3DThe_mental_gland_of_Bolitoglossa_nicefor.pdf\u0026Expires=1732391934\u0026Signature=eNAISb-OtqOTN4XgZSGXul5VNPiCCBazEDu6zL2z0NSna~zlsUjGjRJ3QVDP7FMT6f8q6j~dVAbXrRaNUrRGYdIqXg4FWbZK-MljTy~JC1VcxME8sJsMuOnvt2li3UgY1bPJ0go7j3U525X~QFjn7tpn36xtR7DucttUI34YbfMePQ8G-eYjBu11UN9bar57Sn8DhF6eoRPQHe1EgNQ2IxvvPV~WiffG4SErIhZlJlp4~XWSQTWabD~6AntXZlA5Hj5N0SHB9SX4HFqZdljTohLIyLLlrevXtGzww9uAWFulAOWAN0~nMeW98GtquQt43YbGU6IJdOpCox2slmo-Ug__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":155,"name":"Evolutionary Biology","url":"https://www.academia.edu/Documents/in/Evolutionary_Biology"},{"id":173,"name":"Zoology","url":"https://www.academia.edu/Documents/in/Zoology"},{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":10882,"name":"Evolution","url":"https://www.academia.edu/Documents/in/Evolution"}],"urls":[{"id":1446828,"url":"http://openurl.ingenta.com/content/xref?genre=article\u0026issn=0173-5373\u0026volume=30\u0026issue=4\u0026spage=561"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="3731247"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/3731247/Ontogeny_of_the_vertebral_column_of_Eleutherodactylus_johnstonei_Anura_Eleutherodactylidae_reveals_heterochronies_relative_to_metamorphic_frogs"><img alt="Research paper thumbnail of Ontogeny of the vertebral column of Eleutherodactylus johnstonei (Anura: Eleutherodactylidae) reveals heterochronies relative to metamorphic frogs.

Lack of investment in parental care results in high annual fecundities of female parasitic birds. Brood parasites lay eggs in series or clutches, separated by gaps or non-laying intervals of a few days, but they may continuously lay for prolonged periods. In tropical latitudes, the fecundity of female shiny cowbirds (Molothrus bonariensis) has been estimated to be 120 eggs per year in a six-month breeding season, a fecundity that is paralleled only by domestic fowl. However, no detailed morphological descriptions of the reproductive tracts of brood parasites are available. We studied the reproductive tract of female shiny cowbirds in northeastern Colombia, searching for morphological features that might be related to this high fecundity. The reproductive tracts of female shiny cowbird showed no departures from the standard morphology or follicular dynamics known for birds with different postural patterns and fecundities, suggesting that high fecundity in cowbirds does not require a specialized reproductive tract. Instead, explanations must be sought at physiological levels.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="f85ea01bb2aa30d923488b7437320833" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":49979560,"asset_id":4224763,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/49979560/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="4224763"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="4224763"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 4224763; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=4224763]").text(description); $(".js-view-count[data-work-id=4224763]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 4224763; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='4224763']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 4224763, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "f85ea01bb2aa30d923488b7437320833" } } $('.js-work-strip[data-work-id=4224763]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":4224763,"title":"Ovarian and oviductal morphology of a brood parasitic bird, Molothrus bonariensis (Passeriformes, Icteridae): Ovarian and oviductal morphology of M. bonariensis","translated_title":"","metadata":{"abstract":"Brood parasitic birds such as cowbirds (Molothrus spp., Icteridae) lay their eggs in the nests of other species, abandoning them to be incubated and raised by the hosts.

The male reproductive tract of P. magdalenae is composed of testes, efferent ducts, epididymides, deferent ducts, seminal vesicles, Leydig, alkaline, and clasper glands, and claspers, all of which are paired and functional. Four sexual maturity stages were established: immature, maturing, reproductively active, and resting. The degree of claspers calcification is also a good indicator of sexual maturity in this species. The testes are lobulated, each lobe contains numerous spermatocysts which are organized in zones and are displaced radially from germinal papillae to the spermatozoa zone where individual spermatozoa are conveyed to the efferent ducts. The epididymis can be regionalized in head, body, and tail; these regions are distinguished by external pigmentation and by the epithelium lining configuration. The tail of the epididymis is connected with the deferent duct and this, in turn, with the seminal vesicle. The spermatozoa are organized in spermatozeugmata which begin to form in the deferent duct; this latter organ is attached laterally at the Leydig gland that is composed by simple glandular units. Irregular and vesicular secretions can be found in the genital ducts. These secretions might be associated with the maturation of the spermatozoa and formation of spermatozeugmata. The male reproductive tract of P. magdalenae is similar to other elasmobranchs; however, two types of primary spermatogonia, an epididymis internally regionalized, and the presence and structure of spermatozeugmata are specific features not yet described in freshwater stingrays. Most of the year, the males were reproductively active, however, few resting adult males occurred during one of the months of the lowest waters. J.

Geobatrachus walkeri is a frog that belongs to a monotypic genus and is endemic to the Sierra Nevada de Santa Marta, Colombia. The species inhabits different microhabitats between 2 000 to 3 500m altitude, including the leaf litter of a pine plantation. To understand its reproductive ecology, we conducted eight frog samplings, covering the rainy and dry seasons, and two habitat types (secondary native forest and pine plantation) during 2010-2011. For this study, we also included data obtained from five previous similar samplings undertaken during 2008-2009. The pine leaf litter was the main microhabitat where frogs were found; we heard choruses of six-ten calling males during all sampled months, and observed the frogs having diurnal and nocturnal activity. Regardless of the year of study, the population consisted of neonates recruited several times of the year, a large number of juveniles with a wide range of body sizes, and fewer adults with a narrower range of body size. The histological analyses of the gonads showed that the size at maturity was near 18mm SVL for males and females, and those adult males and females were reproductive active during all sampling months, suggesting a continuous reproductive activity pattern. However, during the dry season, the seminiferous tubules showed a drastically diminished spermatic epithelium although containing abundant luminal spermatozoa, which suggest a reduction in the sperm production at the end of this season. Similarly, frogs of all age categories were significantly more abundant during the early dry season, whereas were significantly less abundant with the advancement of the dryness suggesting that the intensity of the dry season could temporally stop the activity and reproduction of this population.

Their recently ovulated eggs are microlecithal (1-2 mm) and lack fatty yolk platelets; thus, virtually all of the nutrients for embryonic development must pass across the placenta. We quantified the net uptake of nutrients during gestation in an Andean population of Mabuya and compared these results with other matrotrophic skinks and eutherian mammals. Total dry and wet masses, ash and organic content, ions (calcium, potassium, sodium, magnesium, iron), lipids (cholesterol, vitamin E and fatty acids in the major lipid classes-triacylglycerol, phospholipids, cholesteryl ester, free fatty acids), nitrogen (an index of protein) were measured during the different developmental stages throughout gestation, and in neonates. A significant net uptake of inorganic and organic matter was found. This uptake begins slowly during early gestation but accelerates during the last third of gestation when the growth of the embryo is maximal and the allantoplacenta has developed its greatest complexity. The drastic reduction of egg size in this clade is related to the great reduction in the contribution of lecithotrophic nutrients to the embryo, an obligatory placentotrophy from early developmental stages, and the highest placental complexity known in the Reptilia. All of these features converge with features found in eutherian mammals.","publication_date":{"day":1,"month":1,"year":2011,"errors":{}},"publication_name":"Journal of Comparative

Recent developmental studies have provided a basis for understanding lizard autopodial element homology based on developmental and comparative anatomy. In addition, the composition and identity of some carpal and tarsal elements of lizard limbs, and reptiles in general, have been the theme of discussions about their homology compared to non-squamate Lepidosauromorpha and basal Amniota. The study of additional embryonic material from different lizard families may improve our understanding of squamate limb evolution. Here, we analyze limb morphogenesis in the gekkonid lizard Gonatodes albogularis describing patterns of chondrogenesis and ossification from early stages of embryonic development to hatchlings. Our results are in general agreement with previous developmental studies, but we also show that limb development in squamates probably involves more chondrogenic elements for carpal and tarsal morphogenesis, as previously recognized on the grounds of comparative anatomy. We provide evidence for the transitory presence of distal carpale 1 and intermedium in the carpus and tibiale, intermedium, distal centralia, and distal tarsale 2 in the tarsus. Hence, we demonstrate that some elements that were believed to be lost in squamate evolution are conserved as transitory elements during limb development. However, these elements do not represent just phylogenetic burden but may be important for the morphogenesis of the lizard autopodium. J.

The oocyte of the primary follicle is surrounded by a single layer of follicle cells. During the previtellogenic stages, these cells become stratified and differentiated in three cell types: small, intermediate, and large globoid, non pyriform cells. Fluid-filled spaces arise among follicular cells in late previtellogenic follicles and provide evidence of cell lysis. In vitellogenic follicles, the follicular cells constitute a monolayered granulosa with large lacunar spaces; the content of their cytoplasm is released to the perivitelline space where the zona pellucida is formed. The oolemma of younger oocytes presents incipient short projections; as the oocyte grows, these projections become organized in a microvillar surface. During vitellogenesis, cannaliculi develop from the base of the microvilli and internalize materials by endocytosis. In the juxtanuclear ooplasm of early previtellogenic follicles, the Balbiani's vitelline body is found as an aggregate of organelles and lipid droplets; this complex of organelles disperses in the ooplasm during oocyte growth. In late previtellogenesis, membranous organelles are especially abundant in the peripheral ooplasm, whereas abundant vesicles and granular material occur in the medullar ooplasm. The ooplasm of vitellogenic follicles shows a peripheral band constituted by abundant membranous organelles and numerous vesicular bodies, some of them with a small lipoprotein core. No organized yolk platelets, like in lecithotrophic reptiles, were observed. Toward the medullary ooplasm, electron-lucent vesicles become larger in size containing remains of cytoplasmic material in dissolution. The results of this study demonstrate structural similarities between the follicles of this species and other Squamata; however, the ooplasm of the mature oocyte of Mabuya is morphologically similar to the ooplasm of mature oocytes of marsupials, suggesting an interesting evolutionary convergence related to the evolution of placentotrophy and of microlecithal eggs.

these prey were the most important in terms of volume and number. there were no significant differences in the number, type and abundance of prey, as well as in the length and volume of the consumed prey between males and females. there were significant differences between the diet of adults and juveniles. lizards ate prey with similar volumes and lengths throughout the year independent of the rainfall regime. also, there were no significant differences in prey volume and length with regard to the reproductive stages of females and males. the lack of variation in diet in this population suggests a constant availability of prey in the study area. When we compared diet composition of this population with that of other species of Mabuya, we found that diet tends to be similar among the different species and populations of Mabuya in south america. adult lizards showed two activity peaks during the day, before and after midday; this pattern of daily activity was constant throughout the year. Preferred microhabitats used by this population are related to anthropogenic disturbance. the population of the present study seems to have quite wide ecological requirements (generalist diet, use of a wide spectrum of microhabitats and extended daily activity), which allows it to exploit disturbed habitats.","publication_date":{"day":null,"month":null,"year":2010,"errors":{}},"publication_name":"South American Journal of Herpetology","grobid_abstract_attachment_id":49979566},"translated_abstract":null,"internal_url":"https://www.academia.edu/4224756/Diet_Microhabitat_use_and_Daily_Activity_Patterns_of_an_Andean_Population_of_Mabuya_Squamata_Scincidae","translated_internal_url":"","created_at":"2013-08-12T09:16:19.917-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":1211170,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":49979566,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/49979566/thumbnails/1.jpg","file_name":"Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6.pdf","download_url":"https://www.academia.edu/attachments/49979566/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diet_Microhabitat_use_and_Daily_Activity.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/49979566/Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6-libre.pdf?1477829758=\u0026response-content-disposition=attachment%3B+filename%3DDiet_Microhabitat_use_and_Daily_Activity.pdf\u0026Expires=1732391934\u0026Signature=CceTMOTuSTGMoKHhOcDlRj5hNeEv3c9I8ZZt-zelDmtBvA6lzGWg-LRFE~MrdnSUk5wUn15CIC0J05ElKznW1evnlP7iGGd8yPjrxGbCoucEnlXlb-52T581Vu1gUWmYboQvRAblzAuPbs9rQCImeogA4iZhWG~09mY2lG37EYy2k4m2oQBVSBioM0PnBr9Qvxjm2Q7L8tG8yO9x0NqEH52b7jGkHWMBdOe26Nsnch3e3DUn33TGM6LKl88siou9lA5AhbTUYs09yk1STvE7hPy6gWYggs0qSHu7WHW7cHOuMsMl424AnsrJnS3bMblzIQWAHDul9-dZpgeu25VxsA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Diet_Microhabitat_use_and_Daily_Activity_Patterns_of_an_Andean_Population_of_Mabuya_Squamata_Scincidae","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":1211170,"first_name":"Martha Patricia","middle_initials":null,"last_name":"Ramirez-Pinilla","page_name":"MartaRamirez","domain_name":"uis","created_at":"2012-02-15T05:24:58.208-08:00","display_name":"Martha Patricia Ramirez-Pinilla","url":"https://uis.academia.edu/MartaRamirez"},"attachments":[{"id":49979566,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/49979566/thumbnails/1.jpg","file_name":"Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6.pdf","download_url":"https://www.academia.edu/attachments/49979566/download_file?st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&st=MTczMjM4ODMzNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diet_Microhabitat_use_and_Daily_Activity.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/49979566/Diet_Microhabitat_use_and_Daily_Activity20161030-12892-17tnwj6-libre.pdf?1477829758=\u0026response-content-disposition=attachment%3B+filename%3DDiet_Microhabitat_use_and_Daily_Activity.pdf\u0026Expires=1732391934\u0026Signature=CceTMOTuSTGMoKHhOcDlRj5hNeEv3c9I8ZZt-zelDmtBvA6lzGWg-LRFE~MrdnSUk5wUn15CIC0J05ElKznW1evnlP7iGGd8yPjrxGbCoucEnlXlb-52T581Vu1gUWmYboQvRAblzAuPbs9rQCImeogA4iZhWG~09mY2lG37EYy2k4m2oQBVSBioM0PnBr9Qvxjm2Q7L8tG8yO9x0NqEH52b7jGkHWMBdOe26Nsnch3e3DUn33TGM6LKl88siou9lA5AhbTUYs09yk1STvE7hPy6gWYggs0qSHu7WHW7cHOuMsMl424AnsrJnS3bMblzIQWAHDul9-dZpgeu25VxsA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":173,"name":"Zoology","url":"https://www.academia.edu/Documents/in/Zoology"},{"id":441325,"name":"South American","url":"https://www.academia.edu/Documents/in/South_American"},{"id":843856,"name":"Ecological Applications","url":"https://www.academia.edu/Documents/in/Ecological_Applications"}],"urls":[{"id":1446827,"url":"http://www.bioone.org/doi/abs/10.2994/057.005.0107"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="2324354"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/2324354/Microhabitats_for_oviposition_and_male_clutch_attendance_in_Hyalinobatrachium_aureoguttatum_Anura_Centrolenidae_Copeia_2012_4_722_731_2012"><img alt="Research paper thumbnail of Microhabitats for oviposition and male clutch attendance in Hyalinobatrachium aureoguttatum (Anura: Centrolenidae).

The mental gland is an oval shaped pad which develops exclusively in reproductive males. It is composed of 255 to 710 simple glands of merocrine secretion arranged in a dorso-ventral disposition. The outlets of the glands are spindle-shaped or fusiform. Negative stain reaction for AB and PAS is consistent with results of the glandular components of mental glands from other Plethodontidae. Males of this species produce sperm continuously throughout the year: all examined adult males showed conspicuous mental glands. However, an evident and significant increase in the surface area of the mental gland pad, in the density of the glands, and in the number of tubular glands was observed in the males collected during the breeding season. At the histological level, a slight variation was observed among males in the height and diameter of the simple tubular glands, and significant variation was found in the diameter of the secretory granules.

Brood parasites lay eggs in series or clutches, separated by gaps or non-laying intervals of a few days, but they may continuously lay for prolonged periods. In tropical latitudes, the fecundity of female shiny cowbirds (Molothrus bonariensis) has been estimated to be 120 eggs per year in a six-month breeding season, a fecundity that is paralleled only by domestic fowl.
