To design the most effective conservation strategies to address these declines, the nature and timing of the most probable genetic or nongenetic factors behind population collapses need to be identified. We used high\u2010density RADseq genetic markers to determine the demographic history and track population\u2010level exposure of the Knysna seahorse (\n                    <jats:italic>Hippocampus capensis<\/jats:italic>\n                    ), the first syngnathid listed as endangered by the International Union for Conservation of Nature (IUCN), to historical and current threats. Our results revealed an initial link between sea\u2010level fluctuations and settlement for this estuarine endemic species that occurred on a coastline without obvious alternative habitats that were followed by divergence and progressive isolation of the extant populations. Two of the three extant Knysna seahorse populations, those inhabiting estuaries most affected by floods and natural or human\u2010mediated breaching of the estuary mouths, showed severe and continued contractions in effective population size. We illustrated the potential of genomics for the conservation of the most vulnerable species and their fragile ecosystems and highlighted the urgency and type of measures required to maintain species\u2019 persistence and resilience. Our results provide practical insights to help protect this endangered seahorse, namely, the need for proactive management, which is essential for preventing the expected losses of genetic diversity that follow shrinking effective population sizes. Additionally, we showed that hydrological stability and increased substratum availability can foster recoveries without the need for potentially riskier alternatives such as the recently proposed seahorse translocations.\n                  <\/jats:p>","DOI":"10.1111\/cobi.70389","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T09:38:05Z","timestamp":1790156285000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Endangered seahorse genomic data recount a past of enforced isolation and guide future conservation efforts"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6994-4673","authenticated-orcid":false,"given":"Nuno","family":"Monteiro","sequence":"first","affiliation":[{"name":"BIOPOLIS Program in Genomics, Biodiversity and Land Planning CIBIO  Vair\u00e3o Portugal"},{"name":"CIBIO, Centro de Investiga\u00e7\u00e3o em Biodiversidade e Recursos Gen\u00e9ticos, InBIO Laborat\u00f3rio Associado, Campus de Vair\u00e3o Universidade do Porto  Vair\u00e3o Portugal"},{"name":"IUCN SSC Seahorse, Pipefish and Seadragon Specialist Group University of British Columbia  Vancouver British Columbia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc\u00eda","family":"P\u00e9rez\u2010Pardal","sequence":"additional","affiliation":[{"name":"CIBIO, Centro de Investiga\u00e7\u00e3o em Biodiversidade e Recursos Gen\u00e9ticos, InBIO Laborat\u00f3rio Associado, Campus de Vair\u00e3o Universidade do Porto  Vair\u00e3o Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albano","family":"Beja\u2010Pereira","sequence":"additional","affiliation":[{"name":"CIBIO, Centro de Investiga\u00e7\u00e3o em Biodiversidade e Recursos Gen\u00e9ticos, InBIO Laborat\u00f3rio Associado, Campus de Vair\u00e3o Universidade do Porto  Vair\u00e3o Portugal"},{"name":"DGAOT, Faculty of Sciences Universidade do Porto  Porto Portugal"},{"name":"Sustainable Agrifood Production Research Centre (GreenUPorto), INOV4AGRO Universidade do Porto  Vair\u00e3o Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter R.","family":"Teske","sequence":"additional","affiliation":[{"name":"Centre for Ecological Genomics and Wildlife Conservation, Department of Zoology University of Johannesburg \u2010 Auckland Park Kingsway Campus  Johannesburg South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louw","family":"Claassens","sequence":"additional","affiliation":[{"name":"IUCN SSC Seahorse, Pipefish and Seadragon Specialist Group University of British Columbia  Vancouver British Columbia Canada"},{"name":"Department of Zoology &amp; Entomology Rhodes University  Grahamstown South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1016\/j.sajb.2016.07.007","article-title":"Distribution and status of Zostera capensis in South African estuaries\u2014A review","volume":"107","author":"Adams J.
