Worldwide, fire-sensitive shrubs have an important but underresearched life history, and in Australia they are threatened by anthropogenic changes to fire regimes and habitat loss. Typically, adults are killed by fire, but they can also senesce and die if interfire intervals are prolonged. Populations can regenerate from seed banks displaying fire-stimulated germination; however, populations are ephemeral, and true population sizes and connectedness are difficult to estimate. Persoonia hirsuta ssp. evoluta is an endangered, inconspicuous, fire-sensitive shrub with a soil-stored seed bank currently known only from a small number of locations within the fire-prone Sydney Basin. Although it appears highly fragmented and populations are typically small, we predicted that its seed bank would buffer populations against loss of genetic diversity and population differentiation. Methodology. We used microsatellite markers to assess genetic variation within three aboveground populations of P. hirsuta separated by up to 25 km. The largest and most isolated population, at Appin, New South Wales, Australia, occurs on a mine site and may be subject to disturbance. We compared levels of genetic diversity and estimated the mating systems and genetic connectedness of plants within the three sites. Pivotal results. As predicted, all populations displayed similar genetic diversity, as judged by expected heterozygosity and allelic richness, and displayed little differentiation. All populations appear predominantly outcrossed. However, STRUCTURE and principal coordinates analyses showed that Appin individuals were distinct from those at the other locations. Conclusions. Our data imply that even for fire-sensitive species with few aboveground populations, genetic diversity can be maintained by the buffering effect of persistent seed banks with diversity reflecting historically greater interpopulation gene flow. While all P. hirsuta sites support comparable genetic diversity, the preservation of known populations is critical. Conservation efforts should include searches for additional populations, fire-stimulated germination of seed banks, and collection of seed for propagation in a nursery or direct sowing.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="76692635"><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="76692635"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 76692635; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=76692635]").text(description); $(".js-view-count[data-work-id=76692635]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 76692635; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='76692635']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 76692635, 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=76692635]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":76692635,"title":"Low Genetic Differentiation despite Fragmentation in an Endangered Fire-Sensitive Shrub","translated_title":"","metadata":{"abstract":"Premise of research.

However, managing declining populations is more complex and requires knowledge of genetic diversity and interspecific interactions.","internal_url":"https://www.academia.edu/66979243/Research_and_conservation_initiatives_for_the_vulnerable_purple_wood_wattle_A_model_for_plant_species_conservation_in_Australia","translated_internal_url":"","created_at":"2022-01-03T13:30:48.966-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":77972388,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972388/thumbnails/1.jpg","file_name":"viewcontent.pdf","download_url":"https://www.academia.edu/attachments/77972388/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Research_and_conservation_initiatives_fo.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972388/viewcontent-libre.pdf?1641257149=\u0026response-content-disposition=attachment%3B+filename%3DResearch_and_conservation_initiatives_fo.pdf\u0026Expires=1733258328\u0026Signature=dQwfRgwnkRu0Y7B85go2icv3QVRVEMniPxxqdtIL6vpOaabZQf9LSsauegDnFr6-y7jAkRBlDSQ7l8kyr-2viP5iEfOrn3ArFG114IoyV3apZfjlpgz1a-NZPzZFZNhCfCJwFSwyGmkDWDAmo2lg4FVSKBMFr~qGgLwh2UGhh9z0jbTZeVx3QtR8ohzOgRPoQxX6mfMnzkWJSxanDkbjr1n46Bh~c1g12IXN6~T3kd5qpMUMgHs-KwhXOo1QkNxLp9HWr1T4hebg2N445nOAVEg5XijVpy-DYgZMwnwfkA6FavjHQQhc5WtOtaIGaVllHc0SyBk37Sux-EbdzNPBWw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Research_and_conservation_initiatives_for_the_vulnerable_purple_wood_wattle_A_model_for_plant_species_conservation_in_Australia","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":77972388,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972388/thumbnails/1.jpg","file_name":"viewcontent.pdf","download_url":"https://www.academia.edu/attachments/77972388/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Research_and_conservation_initiatives_fo.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972388/viewcontent-libre.pdf?1641257149=\u0026response-content-disposition=attachment%3B+filename%3DResearch_and_conservation_initiatives_fo.pdf\u0026Expires=1733258328\u0026Signature=dQwfRgwnkRu0Y7B85go2icv3QVRVEMniPxxqdtIL6vpOaabZQf9LSsauegDnFr6-y7jAkRBlDSQ7l8kyr-2viP5iEfOrn3ArFG114IoyV3apZfjlpgz1a-NZPzZFZNhCfCJwFSwyGmkDWDAmo2lg4FVSKBMFr~qGgLwh2UGhh9z0jbTZeVx3QtR8ohzOgRPoQxX6mfMnzkWJSxanDkbjr1n46Bh~c1g12IXN6~T3kd5qpMUMgHs-KwhXOo1QkNxLp9HWr1T4hebg2N445nOAVEg5XijVpy-DYgZMwnwfkA6FavjHQQhc5WtOtaIGaVllHc0SyBk37Sux-EbdzNPBWw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":2467,"name":"Conservation Biology","url":"https://www.academia.edu/Documents/in/Conservation_Biology"},{"id":288003,"name":"Plant Biodiversity Conservation","url":"https://www.academia.edu/Documents/in/Plant_Biodiversity_Conservation"}],"urls":[{"id":16026149,"url":"https://ro.uow.edu.au/cgi/viewcontent.cgi?article=4847\u0026context=smhpapers\u0026httpsredir=1\u0026referer="}]}, dispatcherData: dispatcherData });

We investigated the genetic structure of 19 stands of eight to \u003e 1000 plants separated by \u003c 300 km to test for variation in life histories between semi-arid and arid stands to the east and west of the Darling River, respectively. Eight of nine stands east of the Darling were exclusively sexual, whereas most of those to the west were clonal. Three western stands were monoclonal, two were polyploid, and one was a diverse mix of diploid and triploid phenotypes. Bayesian analysis revealed a complex genetic structure within the western stands, whereas the eastern stands formed only two genetic clusters. Conservation of small stands may require augmentation of genotypic diversity. However, most genotypic diversity resides within the eastern stands. Although arid zone stands of A. loderi are not always clonal, clonality and polyploidy are more common in the arid west. Clear demarcation of life histories either side of the Darling River may reflect ancient or contemporary effects of physical disturbance associated with the river channel, or cryptic environmental differences, with sexual and asexual reproduction, respectively, at a selective premium in the semi-arid east and arid west. The restricted distribution of clones and variation in clonality and polyploidy suggests that smaller stands may be vulnerable and warrant individual management.","publication_date":{"day":null,"month":null,"year":2015,"errors":{}},"publication_name":"Biological Journal of the Linnean Society","grobid_abstract_attachment_id":77972413},"translated_abstract":null,"internal_url":"https://www.academia.edu/66979242/Varying_levels_of_clonality_and_ploidy_create_barriers_to_gene_flow_and_challenges_for_conservation_of_an_Australian_arid_zone_ecosystem_engineer_Acacia_loderi","translated_internal_url":"","created_at":"2022-01-03T13:30:48.820-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":77972413,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972413/thumbnails/1.jpg","file_name":"bij12728.pdf","download_url":"https://www.academia.edu/attachments/77972413/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Varying_levels_of_clonality_and_ploidy_c.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972413/bij12728-libre.pdf?1641257146=\u0026response-content-disposition=attachment%3B+filename%3DVarying_levels_of_clonality_and_ploidy_c.pdf\u0026Expires=1733258328\u0026Signature=FO5CQTGyDAV6fG0kNNSSa5lJt9WMrZlNIAHSe32ziW731AYwtej8A~UJ8PYvvYayWSOEbyWmpPbQZZ1LgmInHZjWLWr08gt-2ZxGXWi3YYbO8pOhWqYqaaXJTLC0jVZcDok1zVaSeWwIy2LmOlRDq6VSEkOTwQtqE-CvgfnhoggxFo9ImiW0DuaMfhT1LgSFsvsL2BwSbC38vnTgtEpC3MXKeGVdgdn6MFZmBGOo1jpwjX9zmJBaJlFRkjS8gmCJUynufTfnaDaMmLn4Scph2xgnbmvC3QV8L53E~UgHHAMyZQbdF7LSDYOzkrvI8JpK1taHQVnKRXhkjnybQ1lPhQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Varying_levels_of_clonality_and_ploidy_create_barriers_to_gene_flow_and_challenges_for_conservation_of_an_Australian_arid_zone_ecosystem_engineer_Acacia_loderi","translated_slug":"","page_count":14,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":77972413,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972413/thumbnails/1.jpg","file_name":"bij12728.pdf","download_url":"https://www.academia.edu/attachments/77972413/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Varying_levels_of_clonality_and_ploidy_c.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972413/bij12728-libre.pdf?1641257146=\u0026response-content-disposition=attachment%3B+filename%3DVarying_levels_of_clonality_and_ploidy_c.pdf\u0026Expires=1733258328\u0026Signature=FO5CQTGyDAV6fG0kNNSSa5lJt9WMrZlNIAHSe32ziW731AYwtej8A~UJ8PYvvYayWSOEbyWmpPbQZZ1LgmInHZjWLWr08gt-2ZxGXWi3YYbO8pOhWqYqaaXJTLC0jVZcDok1zVaSeWwIy2LmOlRDq6VSEkOTwQtqE-CvgfnhoggxFo9ImiW0DuaMfhT1LgSFsvsL2BwSbC38vnTgtEpC3MXKeGVdgdn6MFZmBGOo1jpwjX9zmJBaJlFRkjS8gmCJUynufTfnaDaMmLn4Scph2xgnbmvC3QV8L53E~UgHHAMyZQbdF7LSDYOzkrvI8JpK1taHQVnKRXhkjnybQ1lPhQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":47884,"name":"Biological Sciences","url":"https://www.academia.edu/Documents/in/Biological_Sciences"}],"urls":[]}, dispatcherData: dispatcherData });

However, few studies have determined if pollination by the honeybee Apis mellifera (the world's most widely introduced pollinator) reduces offspring quality when compared with pollination by native birds. The Australian Proteaceae provides an excellent opportunity to test the impact of honeybees in pollination systems that are adapted to birds and non-flying mammals. Methods We compared the frequency of flower visitation and foraging behaviour of birds and insects within seven populations of Banksia ericifolia. Banksia ericifolia is hermaphroditic and has large nectar-rich, orange inflorescences typical of bird and mammal pollinated species. For a subset of the study populations, we compared the quality of seed produced via an exclusion treatment (that only allowed invertebrates to access flowers) with an open-pollination treatment (potentially visited by mammals, birds and invertebrates), by measuring seed weight, germination rates (T 50), percent germination, seedling height after 14 days since the emergence of the cotyledon and time to emergence of the cotyledon. Important Findings Apis mellifera was the only apparent insect pollinator and the most frequent flower visitor, while the open treatment inflorescences were also frequently visited by avian pollinators, primarily honeyeater species. The foraging behaviour of honeybees and honeyeaters showed striking differences that potentially affect patterns of pollen transfer. Honeybees made significantly greater proportions of within cf. among plant movements and only 30% (n = 48) of honeybees foraged for pollen (nectar foragers carried no pollen) whilst all birds were observed to contact both stigmas and anthers when foraging for nectar. Despite these fundamental differences in behaviour, there was little effect of treatment on seed set or quality. Our data show that while honeybees appear to alter patterns of pollen transfer within B. ericifolia populations, they do not impact reproductive rates or performance of early life-stages.","publication_date":{"day":null,"month":null,"year":2016,"errors":{}},"publication_name":"Journal of Plant Ecology","grobid_abstract_attachment_id":77972393},"translated_abstract":null,"internal_url":"https://www.academia.edu/66979223/Do_introduced_honeybees_affect_seed_set_and_seed_quality_in_a_plant_adapted_for_bird_pollination","translated_internal_url":"","created_at":"2022-01-03T13:30:12.371-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":77972393,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972393/thumbnails/1.jpg","file_name":"rtw064.pdf","download_url":"https://www.academia.edu/attachments/77972393/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Do_introduced_honeybees_affect_seed_set.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972393/rtw064-libre.pdf?1641257148=\u0026response-content-disposition=attachment%3B+filename%3DDo_introduced_honeybees_affect_seed_set.pdf\u0026Expires=1733258329\u0026Signature=Opo1JmiV81xgMCemmZjesU0kIefuAcREvmgjRXCKWG4Uv767QKzs86zjSAkDDXAgZHeJpRRrouEY-QsuJ5O3G~MnRKTnPTnNNxilnM8kFr4NHliqeDnsdm9NiDtNJp~LEdPcy6bLcAv~NKjZHSgBfjRZhil4LNXdZSCAP5XwF-JYvokchSFDPqxNqzKBLJN7oVJjFqESmhvicJgqHkql6kFbqpS3vTuA6-iVdhGg6CzH9hYU4aqZACWz3s3~SeTtNh5lG2Y5BiHtZVRIPlpiUGcvGFkijUDJE2y32npvnzeniLK0C~IQ680rvwRJ8xRAI0ByEDcN~E5IR7sJQbfPmw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Do_introduced_honeybees_affect_seed_set_and_seed_quality_in_a_plant_adapted_for_bird_pollination","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":77972393,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972393/thumbnails/1.jpg","file_name":"rtw064.pdf","download_url":"https://www.academia.edu/attachments/77972393/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Do_introduced_honeybees_affect_seed_set.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972393/rtw064-libre.pdf?1641257148=\u0026response-content-disposition=attachment%3B+filename%3DDo_introduced_honeybees_affect_seed_set.pdf\u0026Expires=1733258329\u0026Signature=Opo1JmiV81xgMCemmZjesU0kIefuAcREvmgjRXCKWG4Uv767QKzs86zjSAkDDXAgZHeJpRRrouEY-QsuJ5O3G~MnRKTnPTnNNxilnM8kFr4NHliqeDnsdm9NiDtNJp~LEdPcy6bLcAv~NKjZHSgBfjRZhil4LNXdZSCAP5XwF-JYvokchSFDPqxNqzKBLJN7oVJjFqESmhvicJgqHkql6kFbqpS3vTuA6-iVdhGg6CzH9hYU4aqZACWz3s3~SeTtNh5lG2Y5BiHtZVRIPlpiUGcvGFkijUDJE2y32npvnzeniLK0C~IQ680rvwRJ8xRAI0ByEDcN~E5IR7sJQbfPmw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":1360,"name":"Plant Ecology","url":"https://www.academia.edu/Documents/in/Plant_Ecology"},{"id":5541,"name":"Plant Biology","url":"https://www.academia.edu/Documents/in/Plant_Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"}],"urls":[]}, dispatcherData: dispatcherData });

We hypothesised that, as observed in many terrestrial forests, small stands (plants) would experience lower pollinator densities and altered pollinator behaviour and visitation and, in consequence, would display reduced pollen deposition as compared with large stands (\u003e10,000 plants). Nevertheless, we recognise that such predictions may be overly simplistic because within this region A. marina attracts a diversity of flower visitors, but its only significant pollinator is the exotic honeybee Apis mellifera. Moreover, it is unclear how readily A. mellifera moves among groups of plants within different mangrove stands of varying sizes separated either by water or urban habitat matrix. Our detailed surveys within pairs of large and small stands in two locations support the predictions that pollinator density and pollen deposition are reduced or altered within small stands. Within small stands honeybee abundance and pollen deposition were on average reduced significantly by 84 and 61 %, respectively. Moreover, within small stands there was a non-significant 12 % increase in the mean time that honeybees spent foraging on individual plants and hence potentially depositing self pollen. Taken together, our data indicate that fragmentation affects the performance of A. mellifera as a pollinator of A. marina and reduce pollinator abundance, leading to pollen limitation in small as compared to large stands, which may negatively affect reproductive output.","publication_name":"Plant Ecology","grobid_abstract_attachment_id":71626744},"translated_abstract":null,"internal_url":"https://www.academia.edu/56049440/Effects_of_stand_size_on_pollination_in_temperate_populations_of_the_mangrove_Avicennia_marina","translated_internal_url":"","created_at":"2021-10-06T13:19:56.471-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":71626744,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626744/thumbnails/1.jpg","file_name":"viewcontent.pdf","download_url":"https://www.academia.edu/attachments/71626744/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_stand_size_on_pollination_in.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626744/viewcontent-libre.pdf?1633556184=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_stand_size_on_pollination_in.pdf\u0026Expires=1733258329\u0026Signature=RAJKf-9XIGgTrC3hsAKbqMxGdKyyF2tFkRpT3I~-mSGokDyUeboQJznh-HHQ-mpU4XrhR7ZfdrkIPIOzap3U6boVEOnMbl4VmYxqaoFr0~hvRYyWTmVRHGboVGUqySjYiLPbMPG92oGfKEbZ4s2YmOdab1LWBdQxIwwguJRDVCkvX5ygpGkgDgwYfdYfu0VVp85HnPNeRQx3WsFxALicutw-wM1x0asNjIX89mUYZ187m7~9GDzjK0G7GB9F~ANIAHNGAA8KKjFjwpxv8k9sNYw3ftVCwJ0SjIscPw2aDuAeKfVEd1OkG9G1mCsHtXlh~ZDJNKFlon~QHRF-z5kdWg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Effects_of_stand_size_on_pollination_in_temperate_populations_of_the_mangrove_Avicennia_marina","translated_slug":"","page_count":27,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":71626744,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626744/thumbnails/1.jpg","file_name":"viewcontent.pdf","download_url":"https://www.academia.edu/attachments/71626744/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_stand_size_on_pollination_in.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626744/viewcontent-libre.pdf?1633556184=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_stand_size_on_pollination_in.pdf\u0026Expires=1733258329\u0026Signature=RAJKf-9XIGgTrC3hsAKbqMxGdKyyF2tFkRpT3I~-mSGokDyUeboQJznh-HHQ-mpU4XrhR7ZfdrkIPIOzap3U6boVEOnMbl4VmYxqaoFr0~hvRYyWTmVRHGboVGUqySjYiLPbMPG92oGfKEbZ4s2YmOdab1LWBdQxIwwguJRDVCkvX5ygpGkgDgwYfdYfu0VVp85HnPNeRQx3WsFxALicutw-wM1x0asNjIX89mUYZ187m7~9GDzjK0G7GB9F~ANIAHNGAA8KKjFjwpxv8k9sNYw3ftVCwJ0SjIscPw2aDuAeKfVEd1OkG9G1mCsHtXlh~ZDJNKFlon~QHRF-z5kdWg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":1360,"name":"Plant Ecology","url":"https://www.academia.edu/Documents/in/Plant_Ecology"},{"id":5541,"name":"Plant Biology","url":"https://www.academia.edu/Documents/in/Plant_Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"}],"urls":[{"id":12406507,"url":"http://link.springer.com/content/pdf/10.1007/s11258-014-0374-3"}]}, dispatcherData: dispatcherData });

Such variation is expected to be selected for in disturbance-prone environments to allow germination into inherently variable regeneration niches. However, there are few demonstrations that heteromorphic seed characteristics should be favored by selection or how they may be maintained. In fire-prone ecosystems, seed heteromorphism is found in the temperatures needed to break physical dormancy, with seeds responding to high or low temperatures, ensuring emergence under variable fire-regime-related soil heating. Because of the relationship between dormancy-breaking temperature thresholds and fire severity, we hypothesize that different post-fire resource conditions have selected for covarying seedling traits, which contribute to maintenance of such heteromorphism. Seeds with low thresholds emerge into competitive conditions, either after low-severity fire or in vegetation gaps, and are therefore likely to experience selection for seedling characteristics that make them good competitors. On the other hand, high-temperature-threshold seeds would emerge into less competitive environments, indicative of stand-clearing high-severity fires, and would not experience the same selective forces. We identified high and low-threshold seed morphs via dormancy-breaking heat treatments and germination trials for two study species and compared seed mass and other morphological characteristics between morphs. We then grew seedlings from the two different morphs, with and without competition, and measured growth and biomass allocation as indicators of seedling performance. Seedlings from low-threshold seeds of both species performed better than their high-threshold counterparts, growing more quickly under competitive conditions, confirming that different performance can result from this seed characteristic. Seed mass or appearance did not differ between morphs, indicating that dormancy-breaking temperature threshold variation is a form of cryptic heteromorphism. The potential shown for the selective influence of different post-fire environmental conditions on seedling performance provides evidence of a mechanism for the maintenance of heteromorphic variation in dormancy-breaking temperature thresholds.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="56049439"><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="56049439"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 56049439; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=56049439]").text(description); $(".js-view-count[data-work-id=56049439]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 56049439; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='56049439']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 56049439, 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=56049439]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":56049439,"title":"Seedling performance covaries with dormancy thresholds: maintaining cryptic seed heteromorphism in a fire-prone system","translated_title":"","metadata":{"abstract":"The production of morphologically different seeds or fruits by the same individual plant is known as seed heteromorphism.

The six separate reefs lie within two dierent reef complexes. Twenty-two enzymes were screened on ®ve buer systems, but only ®ve polymorphic loci (Gpi-1, Gdh-1, Lgg-2, Lpp-1, Est-1) could be consistently resolved. No signi®cant dierences in allelic frequencies were detected among the six sites. All local collections were genotypically diverse, with evidence of only very limited clonal replication at each site. Indeed, the ratio of observed to expected genotypic diversity (mean Go:Ge=0.640.05 SD), the ratio of observed number of genotypes to the number of individuals (mean Ng:N=0.650.04 SE), and deviations from the Hardy± Weinberg equilibrium indicate that sexual reproduction plays a major role in the maintenance of the populations. No genetic dierentiation was found either within (FSR=0.0260.003 SE) or between (FRT=0.000 0.001 SE) reef complexes. The homogeneity of the gene frequencies across the six reefs strongly supports the assumption that the KwaZulu-Natal reef complexes are highly connected by gene¯ow (Nem=44). The reefs in the southern and central reef complexes along the northern Maputaland coastline can therefore be considered part of a single

traits (e.g. inode of reproduction, growth rate, longevity and dispersal) both locally and regionally throughout the Indo-Pacific Ocean. Dispersal may b e achieved by the settlement of sexually or asexually generated brooded planula larvae, by broadcast spawning or more locally through asexual fragmentation of large colonies. In the present study, we conducted a hierarchical survey of allozyme variation within and among reef-crest sites on 3 mid-shelf reefs separated by up to 1200 km on the Great Barrier Reef (GBR), Australia. Our objective was to use allozyme data (1) to quantify local and reglonal patterns of varlatlon in P, damicornis (along the northeastern coast of Australia), (2) to determine the relative contr~bution of sexual versus asexual production of planulae in P damicornis, and (3) to estimate levels of gene flow among adlacent sites (\u003e5 km apart) and among reefs separated by 500 to 1200 km. High levels of genotypic dlvers~ty in our samples of P. darn~cornis imply that dispersive propagules in this species are produced sexually rather than asexually along the length of the GBR. Corals a t all sites displayed the same level of multi-locus genotypic diversity expected for randomly mating, sexually derived populations, and the majority of individual colonies possessed unique 7-locus genotypes. We also detected consistent deficits of heterozygotes within each collection (from 3 local sites on each of the 3 widely spaced reefs). This pattern is consistent with the predicted effects of sexual reproduction associated with some localised dispersal of gametes or larvae (although other explanations cannot be excluded). Furthermore, each reef was genetically subdivided, suggesting that larval recruitment was localised and that these populations are slightly inbred: hierarchical analysis of the standardised genetic variances (FsT) (estimated as Weir \u0026 Cockerham's 0) revealed that, although there was only moderate variation among all 9 sites (FST = 0.055 t 0.029), more variation was found among sites within reefs (F,, = 0.035 * 0.04 to 0.088 2 0.033) than among distant reefs = 0.008 * 0.014) This homogeneity of gene frequencies across widely separated reefs lmplles that reefs are connected by high levels of gene flow (.V,~m = 31) and that local popu-lat~ons of P. damlcornls separated by \u003el000 km can interbreed sufficiently to maintain a consistent sulte of life-history characters.","publication_date":{"day":null,"month":null,"year":1997,"errors":{}},"publication_name":"Marine Ecology Progress Series","grobid_abstract_attachment_id":71626787},"translated_abstract":null,"internal_url":"https://www.academia.edu/56049435/Genetic_differentiation_reproductive_mode_and_gene_flow_in_the_brooding_coral_Pocillopora_damicornis_along_the_Great_Barrier_Reef_Australia","translated_internal_url":"","created_at":"2021-10-06T13:19:55.981-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":71626787,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626787/thumbnails/1.jpg","file_name":"Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf","download_url":"https://www.academia.edu/attachments/71626787/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Genetic_differentiation_reproductive_mod.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626787/Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf?1633553921=\u0026response-content-disposition=attachment%3B+filename%3DGenetic_differentiation_reproductive_mod.pdf\u0026Expires=1733258329\u0026Signature=gMboVzrya-bt3Ly5jwEzR-1hvQ--uoW-krxlmbB7S~w5op91Ik3sxcOpW0ANcIM~8mMI5Wk9kp7p8xYXHPwp4NJDkeTETB12efOUglJMejyOF02VFrttYi84okHqm1DkFkXYpL14kp~XylWG0nRiyfkmuxI4Ok56bBUrDO~b8iAfRbihvlsa7tdC1Gew0O79Zkzl1d3IkvNRqjieLFqje5A5fBSUu-29JYBzTEG70Dh7KTSWJfUufdfcrbUKcp5Yc8dEJlaLJWEBAbeCWAPHxKboYUbv98tXOL4s2uVIP3jQPCUx0NyOXyRNGjJQXGKpnB-jnuQbjmkD2EVFOtGyZg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Genetic_differentiation_reproductive_mode_and_gene_flow_in_the_brooding_coral_Pocillopora_damicornis_along_the_Great_Barrier_Reef_Australia","translated_slug":"","page_count":13,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":71626787,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626787/thumbnails/1.jpg","file_name":"Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf","download_url":"https://www.academia.edu/attachments/71626787/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Genetic_differentiation_reproductive_mod.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626787/Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf?1633553921=\u0026response-content-disposition=attachment%3B+filename%3DGenetic_differentiation_reproductive_mod.pdf\u0026Expires=1733258329\u0026Signature=gMboVzrya-bt3Ly5jwEzR-1hvQ--uoW-krxlmbB7S~w5op91Ik3sxcOpW0ANcIM~8mMI5Wk9kp7p8xYXHPwp4NJDkeTETB12efOUglJMejyOF02VFrttYi84okHqm1DkFkXYpL14kp~XylWG0nRiyfkmuxI4Ok56bBUrDO~b8iAfRbihvlsa7tdC1Gew0O79Zkzl1d3IkvNRqjieLFqje5A5fBSUu-29JYBzTEG70Dh7KTSWJfUufdfcrbUKcp5Yc8dEJlaLJWEBAbeCWAPHxKboYUbv98tXOL4s2uVIP3jQPCUx0NyOXyRNGjJQXGKpnB-jnuQbjmkD2EVFOtGyZg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":173,"name":"Zoology","url":"https://www.academia.edu/Documents/in/Zoology"},{"id":4313,"name":"Gene Flow","url":"https://www.academia.edu/Documents/in/Gene_Flow"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"},{"id":282140,"name":"Great Barrier Reef","url":"https://www.academia.edu/Documents/in/Great_Barrier_Reef"},{"id":319956,"name":"Genetic Differentiation","url":"https://www.academia.edu/Documents/in/Genetic_Differentiation"},{"id":1828989,"name":"MEPS","url":"https://www.academia.edu/Documents/in/MEPS"}],"urls":[{"id":12406503,"url":"http://int-res.com/abstracts/meps/v159/p175-187"}]}, dispatcherData: dispatcherData });

Worldwide, fire-sensitive shrubs have an important but underresearched life history, and in Australia they are threatened by anthropogenic changes to fire regimes and habitat loss. Typically, adults are killed by fire, but they can also senesce and die if interfire intervals are prolonged. Populations can regenerate from seed banks displaying fire-stimulated germination; however, populations are ephemeral, and true population sizes and connectedness are difficult to estimate. Persoonia hirsuta ssp. evoluta is an endangered, inconspicuous, fire-sensitive shrub with a soil-stored seed bank currently known only from a small number of locations within the fire-prone Sydney Basin. Although it appears highly fragmented and populations are typically small, we predicted that its seed bank would buffer populations against loss of genetic diversity and population differentiation. Methodology. We used microsatellite markers to assess genetic variation within three aboveground populations of P. hirsuta separated by up to 25 km. The largest and most isolated population, at Appin, New South Wales, Australia, occurs on a mine site and may be subject to disturbance. We compared levels of genetic diversity and estimated the mating systems and genetic connectedness of plants within the three sites. Pivotal results. As predicted, all populations displayed similar genetic diversity, as judged by expected heterozygosity and allelic richness, and displayed little differentiation. All populations appear predominantly outcrossed. However, STRUCTURE and principal coordinates analyses showed that Appin individuals were distinct from those at the other locations. Conclusions. Our data imply that even for fire-sensitive species with few aboveground populations, genetic diversity can be maintained by the buffering effect of persistent seed banks with diversity reflecting historically greater interpopulation gene flow. While all P. hirsuta sites support comparable genetic diversity, the preservation of known populations is critical. Conservation efforts should include searches for additional populations, fire-stimulated germination of seed banks, and collection of seed for propagation in a nursery or direct sowing.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="76692635"><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="76692635"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 76692635; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=76692635]").text(description); $(".js-view-count[data-work-id=76692635]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 76692635; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='76692635']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 76692635, 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=76692635]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":76692635,"title":"Low Genetic Differentiation despite Fragmentation in an Endangered Fire-Sensitive Shrub","translated_title":"","metadata":{"abstract":"Premise of research.

Worldwide, fire-sensitive shrubs have an important but underresearched life history, and in Australia they are threatened by anthropogenic changes to fire regimes and habitat loss. Typically, adults are killed by fire, but they can also senesce and die if interfire intervals are prolonged. Populations can regenerate from seed banks displaying fire-stimulated germination; however, populations are ephemeral, and true population sizes and connectedness are difficult to estimate. Persoonia hirsuta ssp. evoluta is an endangered, inconspicuous, fire-sensitive shrub with a soil-stored seed bank currently known only from a small number of locations within the fire-prone Sydney Basin. Although it appears highly fragmented and populations are typically small, we predicted that its seed bank would buffer populations against loss of genetic diversity and population differentiation. Methodology. We used microsatellite markers to assess genetic variation within three aboveground populations of P. hirsuta separated by up to 25 km. The largest and most isolated population, at Appin, New South Wales, Australia, occurs on a mine site and may be subject to disturbance. We compared levels of genetic diversity and estimated the mating systems and genetic connectedness of plants within the three sites. Pivotal results. As predicted, all populations displayed similar genetic diversity, as judged by expected heterozygosity and allelic richness, and displayed little differentiation. All populations appear predominantly outcrossed. However, STRUCTURE and principal coordinates analyses showed that Appin individuals were distinct from those at the other locations. Conclusions. Our data imply that even for fire-sensitive species with few aboveground populations, genetic diversity can be maintained by the buffering effect of persistent seed banks with diversity reflecting historically greater interpopulation gene flow. While all P. hirsuta sites support comparable genetic diversity, the preservation of known populations is critical.

We investigated the genetic structure of 19 stands of eight to \u003e 1000 plants separated by \u003c 300 km to test for variation in life histories between semi-arid and arid stands to the east and west of the Darling River, respectively. Eight of nine stands east of the Darling were exclusively sexual, whereas most of those to the west were clonal. Three western stands were monoclonal, two were polyploid, and one was a diverse mix of diploid and triploid phenotypes. Bayesian analysis revealed a complex genetic structure within the western stands, whereas the eastern stands formed only two genetic clusters. Conservation of small stands may require augmentation of genotypic diversity. However, most genotypic diversity resides within the eastern stands. Although arid zone stands of A. loderi are not always clonal, clonality and polyploidy are more common in the arid west. Clear demarcation of life histories either side of the Darling River may reflect ancient or contemporary effects of physical disturbance associated with the river channel, or cryptic environmental differences, with sexual and asexual reproduction, respectively, at a selective premium in the semi-arid east and arid west. The restricted distribution of clones and variation in clonality and polyploidy suggests that smaller stands may be vulnerable and warrant individual management.","publication_date":{"day":null,"month":null,"year":2015,"errors":{}},"publication_name":"Biological Journal of the Linnean Society","grobid_abstract_attachment_id":77972413},"translated_abstract":null,"internal_url":"https://www.academia.edu/66979242/Varying_levels_of_clonality_and_ploidy_create_barriers_to_gene_flow_and_challenges_for_conservation_of_an_Australian_arid_zone_ecosystem_engineer_Acacia_loderi","translated_internal_url":"","created_at":"2022-01-03T13:30:48.820-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":77972413,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972413/thumbnails/1.jpg","file_name":"bij12728.pdf","download_url":"https://www.academia.edu/attachments/77972413/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Varying_levels_of_clonality_and_ploidy_c.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972413/bij12728-libre.pdf?1641257146=\u0026response-content-disposition=attachment%3B+filename%3DVarying_levels_of_clonality_and_ploidy_c.pdf\u0026Expires=1733258328\u0026Signature=FO5CQTGyDAV6fG0kNNSSa5lJt9WMrZlNIAHSe32ziW731AYwtej8A~UJ8PYvvYayWSOEbyWmpPbQZZ1LgmInHZjWLWr08gt-2ZxGXWi3YYbO8pOhWqYqaaXJTLC0jVZcDok1zVaSeWwIy2LmOlRDq6VSEkOTwQtqE-CvgfnhoggxFo9ImiW0DuaMfhT1LgSFsvsL2BwSbC38vnTgtEpC3MXKeGVdgdn6MFZmBGOo1jpwjX9zmJBaJlFRkjS8gmCJUynufTfnaDaMmLn4Scph2xgnbmvC3QV8L53E~UgHHAMyZQbdF7LSDYOzkrvI8JpK1taHQVnKRXhkjnybQ1lPhQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Varying_levels_of_clonality_and_ploidy_create_barriers_to_gene_flow_and_challenges_for_conservation_of_an_Australian_arid_zone_ecosystem_engineer_Acacia_loderi","translated_slug":"","page_count":14,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":77972413,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972413/thumbnails/1.jpg","file_name":"bij12728.pdf","download_url":"https://www.academia.edu/attachments/77972413/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Varying_levels_of_clonality_and_ploidy_c.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972413/bij12728-libre.pdf?1641257146=\u0026response-content-disposition=attachment%3B+filename%3DVarying_levels_of_clonality_and_ploidy_c.pdf\u0026Expires=1733258328\u0026Signature=FO5CQTGyDAV6fG0kNNSSa5lJt9WMrZlNIAHSe32ziW731AYwtej8A~UJ8PYvvYayWSOEbyWmpPbQZZ1LgmInHZjWLWr08gt-2ZxGXWi3YYbO8pOhWqYqaaXJTLC0jVZcDok1zVaSeWwIy2LmOlRDq6VSEkOTwQtqE-CvgfnhoggxFo9ImiW0DuaMfhT1LgSFsvsL2BwSbC38vnTgtEpC3MXKeGVdgdn6MFZmBGOo1jpwjX9zmJBaJlFRkjS8gmCJUynufTfnaDaMmLn4Scph2xgnbmvC3QV8L53E~UgHHAMyZQbdF7LSDYOzkrvI8JpK1taHQVnKRXhkjnybQ1lPhQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":47884,"name":"Biological Sciences","url":"https://www.academia.edu/Documents/in/Biological_Sciences"}],"urls":[]}, dispatcherData: dispatcherData });

However, few studies have determined if pollination by the honeybee Apis mellifera (the world's most widely introduced pollinator) reduces offspring quality when compared with pollination by native birds. The Australian Proteaceae provides an excellent opportunity to test the impact of honeybees in pollination systems that are adapted to birds and non-flying mammals. Methods We compared the frequency of flower visitation and foraging behaviour of birds and insects within seven populations of Banksia ericifolia. Banksia ericifolia is hermaphroditic and has large nectar-rich, orange inflorescences typical of bird and mammal pollinated species. For a subset of the study populations, we compared the quality of seed produced via an exclusion treatment (that only allowed invertebrates to access flowers) with an open-pollination treatment (potentially visited by mammals, birds and invertebrates), by measuring seed weight, germination rates (T 50), percent germination, seedling height after 14 days since the emergence of the cotyledon and time to emergence of the cotyledon. Important Findings Apis mellifera was the only apparent insect pollinator and the most frequent flower visitor, while the open treatment inflorescences were also frequently visited by avian pollinators, primarily honeyeater species. The foraging behaviour of honeybees and honeyeaters showed striking differences that potentially affect patterns of pollen transfer. Honeybees made significantly greater proportions of within cf. among plant movements and only 30% (n = 48) of honeybees foraged for pollen (nectar foragers carried no pollen) whilst all birds were observed to contact both stigmas and anthers when foraging for nectar. Despite these fundamental differences in behaviour, there was little effect of treatment on seed set or quality. Our data show that while honeybees appear to alter patterns of pollen transfer within B. ericifolia populations, they do not impact reproductive rates or performance of early life-stages.","publication_date":{"day":null,"month":null,"year":2016,"errors":{}},"publication_name":"Journal of Plant Ecology","grobid_abstract_attachment_id":77972393},"translated_abstract":null,"internal_url":"https://www.academia.edu/66979223/Do_introduced_honeybees_affect_seed_set_and_seed_quality_in_a_plant_adapted_for_bird_pollination","translated_internal_url":"","created_at":"2022-01-03T13:30:12.371-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":77972393,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972393/thumbnails/1.jpg","file_name":"rtw064.pdf","download_url":"https://www.academia.edu/attachments/77972393/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Do_introduced_honeybees_affect_seed_set.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972393/rtw064-libre.pdf?1641257148=\u0026response-content-disposition=attachment%3B+filename%3DDo_introduced_honeybees_affect_seed_set.pdf\u0026Expires=1733258329\u0026Signature=Opo1JmiV81xgMCemmZjesU0kIefuAcREvmgjRXCKWG4Uv767QKzs86zjSAkDDXAgZHeJpRRrouEY-QsuJ5O3G~MnRKTnPTnNNxilnM8kFr4NHliqeDnsdm9NiDtNJp~LEdPcy6bLcAv~NKjZHSgBfjRZhil4LNXdZSCAP5XwF-JYvokchSFDPqxNqzKBLJN7oVJjFqESmhvicJgqHkql6kFbqpS3vTuA6-iVdhGg6CzH9hYU4aqZACWz3s3~SeTtNh5lG2Y5BiHtZVRIPlpiUGcvGFkijUDJE2y32npvnzeniLK0C~IQ680rvwRJ8xRAI0ByEDcN~E5IR7sJQbfPmw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Do_introduced_honeybees_affect_seed_set_and_seed_quality_in_a_plant_adapted_for_bird_pollination","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":77972393,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/77972393/thumbnails/1.jpg","file_name":"rtw064.pdf","download_url":"https://www.academia.edu/attachments/77972393/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Do_introduced_honeybees_affect_seed_set.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/77972393/rtw064-libre.pdf?1641257148=\u0026response-content-disposition=attachment%3B+filename%3DDo_introduced_honeybees_affect_seed_set.pdf\u0026Expires=1733258329\u0026Signature=Opo1JmiV81xgMCemmZjesU0kIefuAcREvmgjRXCKWG4Uv767QKzs86zjSAkDDXAgZHeJpRRrouEY-QsuJ5O3G~MnRKTnPTnNNxilnM8kFr4NHliqeDnsdm9NiDtNJp~LEdPcy6bLcAv~NKjZHSgBfjRZhil4LNXdZSCAP5XwF-JYvokchSFDPqxNqzKBLJN7oVJjFqESmhvicJgqHkql6kFbqpS3vTuA6-iVdhGg6CzH9hYU4aqZACWz3s3~SeTtNh5lG2Y5BiHtZVRIPlpiUGcvGFkijUDJE2y32npvnzeniLK0C~IQ680rvwRJ8xRAI0ByEDcN~E5IR7sJQbfPmw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":1360,"name":"Plant Ecology","url":"https://www.academia.edu/Documents/in/Plant_Ecology"},{"id":5541,"name":"Plant Biology","url":"https://www.academia.edu/Documents/in/Plant_Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"}],"urls":[]}, dispatcherData: dispatcherData });

We hypothesised that, as observed in many terrestrial forests, small stands (plants) would experience lower pollinator densities and altered pollinator behaviour and visitation and, in consequence, would display reduced pollen deposition as compared with large stands (\u003e10,000 plants). Nevertheless, we recognise that such predictions may be overly simplistic because within this region A. marina attracts a diversity of flower visitors, but its only significant pollinator is the exotic honeybee Apis mellifera. Moreover, it is unclear how readily A. mellifera moves among groups of plants within different mangrove stands of varying sizes separated either by water or urban habitat matrix. Our detailed surveys within pairs of large and small stands in two locations support the predictions that pollinator density and pollen deposition are reduced or altered within small stands. Within small stands honeybee abundance and pollen deposition were on average reduced significantly by 84 and 61 %, respectively. Moreover, within small stands there was a non-significant 12 % increase in the mean time that honeybees spent foraging on individual plants and hence potentially depositing self pollen. Taken together, our data indicate that fragmentation affects the performance of A. mellifera as a pollinator of A. marina and reduce pollinator abundance, leading to pollen limitation in small as compared to large stands, which may negatively affect reproductive output.","publication_name":"Plant Ecology","grobid_abstract_attachment_id":71626744},"translated_abstract":null,"internal_url":"https://www.academia.edu/56049440/Effects_of_stand_size_on_pollination_in_temperate_populations_of_the_mangrove_Avicennia_marina","translated_internal_url":"","created_at":"2021-10-06T13:19:56.471-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":71626744,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626744/thumbnails/1.jpg","file_name":"viewcontent.pdf","download_url":"https://www.academia.edu/attachments/71626744/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_stand_size_on_pollination_in.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626744/viewcontent-libre.pdf?1633556184=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_stand_size_on_pollination_in.pdf\u0026Expires=1733258329\u0026Signature=RAJKf-9XIGgTrC3hsAKbqMxGdKyyF2tFkRpT3I~-mSGokDyUeboQJznh-HHQ-mpU4XrhR7ZfdrkIPIOzap3U6boVEOnMbl4VmYxqaoFr0~hvRYyWTmVRHGboVGUqySjYiLPbMPG92oGfKEbZ4s2YmOdab1LWBdQxIwwguJRDVCkvX5ygpGkgDgwYfdYfu0VVp85HnPNeRQx3WsFxALicutw-wM1x0asNjIX89mUYZ187m7~9GDzjK0G7GB9F~ANIAHNGAA8KKjFjwpxv8k9sNYw3ftVCwJ0SjIscPw2aDuAeKfVEd1OkG9G1mCsHtXlh~ZDJNKFlon~QHRF-z5kdWg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Effects_of_stand_size_on_pollination_in_temperate_populations_of_the_mangrove_Avicennia_marina","translated_slug":"","page_count":27,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":71626744,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626744/thumbnails/1.jpg","file_name":"viewcontent.pdf","download_url":"https://www.academia.edu/attachments/71626744/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_stand_size_on_pollination_in.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626744/viewcontent-libre.pdf?1633556184=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_stand_size_on_pollination_in.pdf\u0026Expires=1733258329\u0026Signature=RAJKf-9XIGgTrC3hsAKbqMxGdKyyF2tFkRpT3I~-mSGokDyUeboQJznh-HHQ-mpU4XrhR7ZfdrkIPIOzap3U6boVEOnMbl4VmYxqaoFr0~hvRYyWTmVRHGboVGUqySjYiLPbMPG92oGfKEbZ4s2YmOdab1LWBdQxIwwguJRDVCkvX5ygpGkgDgwYfdYfu0VVp85HnPNeRQx3WsFxALicutw-wM1x0asNjIX89mUYZ187m7~9GDzjK0G7GB9F~ANIAHNGAA8KKjFjwpxv8k9sNYw3ftVCwJ0SjIscPw2aDuAeKfVEd1OkG9G1mCsHtXlh~ZDJNKFlon~QHRF-z5kdWg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":1360,"name":"Plant Ecology","url":"https://www.academia.edu/Documents/in/Plant_Ecology"},{"id":5541,"name":"Plant Biology","url":"https://www.academia.edu/Documents/in/Plant_Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"}],"urls":[{"id":12406507,"url":"http://link.springer.com/content/pdf/10.1007/s11258-014-0374-3"}]}, dispatcherData: dispatcherData });

Such variation is expected to be selected for in disturbance-prone environments to allow germination into inherently variable regeneration niches. However, there are few demonstrations that heteromorphic seed characteristics should be favored by selection or how they may be maintained. In fire-prone ecosystems, seed heteromorphism is found in the temperatures needed to break physical dormancy, with seeds responding to high or low temperatures, ensuring emergence under variable fire-regime-related soil heating. Because of the relationship between dormancy-breaking temperature thresholds and fire severity, we hypothesize that different post-fire resource conditions have selected for covarying seedling traits, which contribute to maintenance of such heteromorphism. Seeds with low thresholds emerge into competitive conditions, either after low-severity fire or in vegetation gaps, and are therefore likely to experience selection for seedling characteristics that make them good competitors. On the other hand, high-temperature-threshold seeds would emerge into less competitive environments, indicative of stand-clearing high-severity fires, and would not experience the same selective forces. We identified high and low-threshold seed morphs via dormancy-breaking heat treatments and germination trials for two study species and compared seed mass and other morphological characteristics between morphs. We then grew seedlings from the two different morphs, with and without competition, and measured growth and biomass allocation as indicators of seedling performance. Seedlings from low-threshold seeds of both species performed better than their high-threshold counterparts, growing more quickly under competitive conditions, confirming that different performance can result from this seed characteristic. Seed mass or appearance did not differ between morphs, indicating that dormancy-breaking temperature threshold variation is a form of cryptic heteromorphism. The potential shown for the selective influence of different post-fire environmental conditions on seedling performance provides evidence of a mechanism for the maintenance of heteromorphic variation in dormancy-breaking temperature thresholds.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="56049439"><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="56049439"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 56049439; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=56049439]").text(description); $(".js-view-count[data-work-id=56049439]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 56049439; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='56049439']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 56049439, 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=56049439]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":56049439,"title":"Seedling performance covaries with dormancy thresholds: maintaining cryptic seed heteromorphism in a fire-prone system","translated_title":"","metadata":{"abstract":"The production of morphologically different seeds or fruits by the same individual plant is known as seed heteromorphism.

The six separate reefs lie within two dierent reef complexes. Twenty-two enzymes were screened on ®ve buer systems, but only ®ve polymorphic loci (Gpi-1, Gdh-1, Lgg-2, Lpp-1, Est-1) could be consistently resolved. No signi®cant dierences in allelic frequencies were detected among the six sites. All local collections were genotypically diverse, with evidence of only very limited clonal replication at each site. Indeed, the ratio of observed to expected genotypic diversity (mean Go:Ge=0.640.05 SD), the ratio of observed number of genotypes to the number of individuals (mean Ng:N=0.650.04 SE), and deviations from the Hardy± Weinberg equilibrium indicate that sexual reproduction plays a major role in the maintenance of the populations. No genetic dierentiation was found either within (FSR=0.0260.003 SE) or between (FRT=0.000 0.001 SE) reef complexes. The homogeneity of the gene frequencies across the six reefs strongly supports the assumption that the KwaZulu-Natal reef complexes are highly connected by gene¯ow (Nem=44). The reefs in the southern and central reef complexes along the northern Maputaland coastline can therefore be considered part of a single

traits (e.g. inode of reproduction, growth rate, longevity and dispersal) both locally and regionally throughout the Indo-Pacific Ocean. Dispersal may b e achieved by the settlement of sexually or asexually generated brooded planula larvae, by broadcast spawning or more locally through asexual fragmentation of large colonies. In the present study, we conducted a hierarchical survey of allozyme variation within and among reef-crest sites on 3 mid-shelf reefs separated by up to 1200 km on the Great Barrier Reef (GBR), Australia. Our objective was to use allozyme data (1) to quantify local and reglonal patterns of varlatlon in P, damicornis (along the northeastern coast of Australia), (2) to determine the relative contr~bution of sexual versus asexual production of planulae in P damicornis, and (3) to estimate levels of gene flow among adlacent sites (\u003e5 km apart) and among reefs separated by 500 to 1200 km. High levels of genotypic dlvers~ty in our samples of P. darn~cornis imply that dispersive propagules in this species are produced sexually rather than asexually along the length of the GBR. Corals a t all sites displayed the same level of multi-locus genotypic diversity expected for randomly mating, sexually derived populations, and the majority of individual colonies possessed unique 7-locus genotypes. We also detected consistent deficits of heterozygotes within each collection (from 3 local sites on each of the 3 widely spaced reefs). This pattern is consistent with the predicted effects of sexual reproduction associated with some localised dispersal of gametes or larvae (although other explanations cannot be excluded). Furthermore, each reef was genetically subdivided, suggesting that larval recruitment was localised and that these populations are slightly inbred: hierarchical analysis of the standardised genetic variances (FsT) (estimated as Weir \u0026 Cockerham's 0) revealed that, although there was only moderate variation among all 9 sites (FST = 0.055 t 0.029), more variation was found among sites within reefs (F,, = 0.035 * 0.04 to 0.088 2 0.033) than among distant reefs = 0.008 * 0.014) This homogeneity of gene frequencies across widely separated reefs lmplles that reefs are connected by high levels of gene flow (.V,~m = 31) and that local popu-lat~ons of P. damlcornls separated by \u003el000 km can interbreed sufficiently to maintain a consistent sulte of life-history characters.","publication_date":{"day":null,"month":null,"year":1997,"errors":{}},"publication_name":"Marine Ecology Progress Series","grobid_abstract_attachment_id":71626787},"translated_abstract":null,"internal_url":"https://www.academia.edu/56049435/Genetic_differentiation_reproductive_mode_and_gene_flow_in_the_brooding_coral_Pocillopora_damicornis_along_the_Great_Barrier_Reef_Australia","translated_internal_url":"","created_at":"2021-10-06T13:19:55.981-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":67338256,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":71626787,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626787/thumbnails/1.jpg","file_name":"Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf","download_url":"https://www.academia.edu/attachments/71626787/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Genetic_differentiation_reproductive_mod.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626787/Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf?1633553921=\u0026response-content-disposition=attachment%3B+filename%3DGenetic_differentiation_reproductive_mod.pdf\u0026Expires=1733258329\u0026Signature=gMboVzrya-bt3Ly5jwEzR-1hvQ--uoW-krxlmbB7S~w5op91Ik3sxcOpW0ANcIM~8mMI5Wk9kp7p8xYXHPwp4NJDkeTETB12efOUglJMejyOF02VFrttYi84okHqm1DkFkXYpL14kp~XylWG0nRiyfkmuxI4Ok56bBUrDO~b8iAfRbihvlsa7tdC1Gew0O79Zkzl1d3IkvNRqjieLFqje5A5fBSUu-29JYBzTEG70Dh7KTSWJfUufdfcrbUKcp5Yc8dEJlaLJWEBAbeCWAPHxKboYUbv98tXOL4s2uVIP3jQPCUx0NyOXyRNGjJQXGKpnB-jnuQbjmkD2EVFOtGyZg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Genetic_differentiation_reproductive_mode_and_gene_flow_in_the_brooding_coral_Pocillopora_damicornis_along_the_Great_Barrier_Reef_Australia","translated_slug":"","page_count":13,"language":"en","content_type":"Work","owner":{"id":67338256,"first_name":"David","middle_initials":null,"last_name":"Ayre","page_name":"DavidAyre","domain_name":"independent","created_at":"2017-08-16T17:29:53.375-07:00","display_name":"David Ayre","url":"https://independent.academia.edu/DavidAyre"},"attachments":[{"id":71626787,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/71626787/thumbnails/1.jpg","file_name":"Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf","download_url":"https://www.academia.edu/attachments/71626787/download_file?st=MTczMzI1NjYzMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Genetic_differentiation_reproductive_mod.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/71626787/Ayre_DJ_Hughes_TP_Standish_RS._Genetic_d20211006-27194-1o8hy6b.pdf?1633553921=\u0026response-content-disposition=attachment%3B+filename%3DGenetic_differentiation_reproductive_mod.pdf\u0026Expires=1733258329\u0026Signature=gMboVzrya-bt3Ly5jwEzR-1hvQ--uoW-krxlmbB7S~w5op91Ik3sxcOpW0ANcIM~8mMI5Wk9kp7p8xYXHPwp4NJDkeTETB12efOUglJMejyOF02VFrttYi84okHqm1DkFkXYpL14kp~XylWG0nRiyfkmuxI4Ok56bBUrDO~b8iAfRbihvlsa7tdC1Gew0O79Zkzl1d3IkvNRqjieLFqje5A5fBSUu-29JYBzTEG70Dh7KTSWJfUufdfcrbUKcp5Yc8dEJlaLJWEBAbeCWAPHxKboYUbv98tXOL4s2uVIP3jQPCUx0NyOXyRNGjJQXGKpnB-jnuQbjmkD2EVFOtGyZg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":173,"name":"Zoology","url":"https://www.academia.edu/Documents/in/Zoology"},{"id":4313,"name":"Gene Flow","url":"https://www.academia.edu/Documents/in/Gene_Flow"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"},{"id":282140,"name":"Great Barrier Reef","url":"https://www.academia.edu/Documents/in/Great_Barrier_Reef"},{"id":319956,"name":"Genetic Differentiation","url":"https://www.academia.edu/Documents/in/Genetic_Differentiation"},{"id":1828989,"name":"MEPS","url":"https://www.academia.edu/Documents/in/MEPS"}],"urls":[{"id":12406503,"url":"http://int-res.com/abstracts/meps/v159/p175-187"}]}, dispatcherData: dispatcherData });
