It makes the effective monitoring, evaluation, and restoration Marine biodiversity is rapidly declining due to anthropogenic activities, yet the key drivers remain elusive, necessitating fine-scale temporal observations that are logistically challenging with traditional methods. Hong Kong, a region of high biodiversity and human density, exemplifies the need for effective monitoring to balance development and conservation. Advances in environmental DNA (eDNA) metabarcoding provide a powerful and innovative approach for assessing biodiversity across temporal scales, offering advantages such as improved detection of cryptic species and expanded spatial-temporal scope. In our recent study, we utilized eDNA to assess marine benthic community dynamics through a full factorial mesocosm experiment using Autonomous Reef Monitoring Structures (ARMS) colonized from Hong Kong sites. This talk will explore key aspects influencing marine eDNA dynamics, including community establishment, temporal impacts of anthropogenic stressors, and variations in eDNA decay rates across species and treatment conditions. Overall, we demonstrate that eDNA metabarcoding provides a detailed and nuanced assessment of biodiversity, enabling the differentiation of spatiotemporal and anthropogenic impacts on community dynamics.&nbsp;<\/p>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n<p><strong>Speaker:<\/strong> Assistant Professor Mathew Seymour<\/p>\n<p><strong>Affiliation: <\/strong>The University of Hong Kong<\/p>\n<p><strong>Time: <\/strong>3:00 PM, Tuesday, May 20, 2025<\/p>\n<p><strong>Venue: <\/strong>Offline: The Conference Hall in Xishuangbanna Headquarter<\/p>\n<p>Online: Tencent Meeting&nbsp; &nbsp;ID\uff1a354 443 862<\/p>\n<p><\/p>\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\n<div class=\"wp-container-1 wp-block-group\"><div class=\"wp-block-group__inner-container\">\n<div style=\"height:0px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Assistant Professor Mathew Seymour<br \/>\nAffiliation: The University of Hong Kong<br \/>\nTime: 3:00 PM, Tuesday, May 20, 2025<\/p>\n","protected":false},"author":2,"featured_media":3549,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[],"_links":{"self":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3548"}],"collection":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3548"}],"version-history":[{"count":3,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3548\/revisions"}],"predecessor-version":[{"id":3556,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3548\/revisions\/3556"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/media\/3549"}],"wp:attachment":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3548"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3548"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3548"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
