In Dungeness crab, settlement\u2010stage megalopae exhibit striking seasonal variation in body size, with early season cohorts consistently larger than later ones. This pattern may result from genetically distinct larval sources or environmentally induced plasticity following the temperature\u2013size rule, which predicts larger body size at cooler temperatures. Here, we evaluated the relative contributions of these potential drivers by analysing megalopae size, regional sea surface temperatures and whole\u2010genome resequencing data from megalopae collected across the ~5\u2010month settlement season throughout Washington, USA. Genomic analyses revealed a subtle coastal ancestry signal in early\u2010arriving megalopae, supporting the hypothesis that these megalopae are of coastal origin. Coastal ancestry was associated with larger megalopae, even after accounting for temperature; however, temperature was a stronger predictor, with a standardised effect size more than three times greater than that of ancestry. A genome\u2010wide association study found no significant associations with megalopae size, suggesting the absence of a strong genotype\u2013phenotype relationship or a lack of statistical power to detect a highly polygenic trait. Together with prior laboratory rearing studies, our findings support a dominant role for environmentally driven plasticity in body size variation. Persistent cohort differences previously observed in juvenile and adult body size raise the possibility that thermal conditions during early life may promote a carryover effect with potentially significant demographic and fishery implications.<\/jats:p>","DOI":"10.1111\/mec.70427","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T01:06:41Z","timestamp":1781053601000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Genes Versus Environment: Body Size Variation Among Recruitment Cohorts of Dungeness Crab"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0255-3111","authenticated-orcid":false,"given":"James L.","family":"Dimond","sequence":"first","affiliation":[{"name":"Shannon Point Marine Center Western Washington University  Anacortes Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9562-2665","authenticated-orcid":false,"given":"Sarah K.","family":"Grossman","sequence":"additional","affiliation":[{"name":"Fisheries Department Swinomish Indian Tribal Community  La Conner Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7741-0919","authenticated-orcid":false,"given":"Emily V.","family":"Buckner","sequence":"additional","affiliation":[{"name":"Puget Sound Restoration Fund  Bainbridge Island Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1964-9776","authenticated-orcid":false,"given":"Claire E.","family":"Cook","sequence":"additional","affiliation":[{"name":"Fisheries Department Swinomish Indian Tribal Community  La Conner Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5739-6793","authenticated-orcid":false,"given":"Katelyn M.","family":"Bosley","sequence":"additional","affiliation":[{"name":"Washington Department of Fish and Wildlife  Port Townsend Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4804-1867","authenticated-orcid":false,"given":"Elizabeth D.","family":"Tobin","sequence":"additional","affiliation":[{"name":"Natural Resources Department Jamestown S\u2019Klallam Tribe  Sequim Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5394-0747","authenticated-orcid":false,"given":"Julie S.","family":"Barber","sequence":"additional","affiliation":[{"name":"Fisheries Department Swinomish Indian Tribal Community  La Conner Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-2504(08)60212-3"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0167980"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v067.i01"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.2983\/0730-8000(2008)27[901:PSODCC]2.0.CO;2"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2020.136610"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tree.2011.01.009"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12237-019-00586-2"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-0981(99)00071-4"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/fshmag\/vuae002"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1139\/f02-101"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/bty560"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8312.2009.01388.x"},{"key":"e_1_2_11_14_1","unstructured":"Cook C.
