This pattern can be driven by dispersal limitation and be thereby informative about dispersal rate (), a parameter of both basic and applied interest. Yet isolation by distance is typically directly estimated from microsatellite or single nucleotide polymorphism data, which does not permit the direct estimation of  or allow to disentangle dispersal limitation from other processes. Blocks of identity by descent (IBD) provide another lens through which isolation by distance may be viewed, and the opportunity to overcome these limitations. Here, we apply this framework to the barred hamlet (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Hypoplectrus puella<\/jats:italic>\n                    <\/jats:styled-content>\n                    ), a reef fish with a 3\u2010week planktonic larval phase. We consider two spatial scales, a continuous stretch of 200\u2009km of reef along the Mesoamerican Barrier Reef in Belize and the Greater Caribbean across &gt;\u20093000\u2009km. The isolation by distance patterns show a good fit with theoretical expectations in Belize, and provide a recent  estimate of 31  (95% confidence interval 23\u201340). The data also show a good fit with theoretical expectations at the Greater Caribbean scale, which is remarkable given the patchy nature of coral reef habitat at this scale, and provide a recent  estimate of 248  (95% confidence interval 231\u2013265). These results highlight the dual role played by coral reef fish larvae, which mediate both local retention and long\u2010distance dispersal.\n                  <\/jats:p>","DOI":"10.1111\/mec.70569","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T03:08:24Z","timestamp":1790651304000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Blocks of Identity by Descent Reveal the Dual Role Played by Reef Fish Larvae for Retention and Dispersal"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9118-9851","authenticated-orcid":false,"given":"Nina","family":"Tombers","sequence":"first","affiliation":[{"name":"Leibniz Center for Tropical Marine Research  Bremen Germany"},{"name":"Institute for Chemistry and Biology of the Marine Environment (ICBM)  Oldenburg Germany"},{"name":"Stuttgart State Museum of Natural History  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8285-9318","authenticated-orcid":false,"given":"Francisco","family":"Campuzano\u2010Jim\u00e9nez","sequence":"additional","affiliation":[{"name":"University of Antwerp  Antwerpen Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1995-9062","authenticated-orcid":false,"given":"Martin","family":"Helmkampf","sequence":"additional","affiliation":[{"name":"Leibniz Center for Tropical Marine Research  Bremen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7631-9355","authenticated-orcid":false,"given":"Janina","family":"Fu\u00df","sequence":"additional","affiliation":[{"name":"Institute\u00a0of\u00a0Clinical Molecular Biology Kiel University  Kiel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2805-2745","authenticated-orcid":false,"given":"W.
