Shallow-water sandy habitats, specifically,\nrepetitively disappeared and regenerated due to seasonal oceanographic\nand climatic eustatic sea-level variations. For its inhabitants, these\nevents translate into populations being cyclically removed or passing by\ndrastic reductions in population size, where the outcome often depends\non the specific life-history modes of the species, determining their\ndispersal, colonization potential and, ultimately, their survival\nability. Therefore, population genetic patterns of marine shallow-water\ninfaunal species can provide powerful clues of such outcomes, as well as\nhow specific geological and ecological settings determine the genetic\nstructure of the species. We herewith test the population structure of\nthe marine infaunal bivalve Ervilia castanea (Montagu, 1803) in the\nsandy habitats of the Azores and Madeira Archipelagos (Northeast and\nCentral Atlantic Ocean), by comparing insular populations with\nconspecifics from the nearest continental shores in mainland Europe.\nLittle to no genetic structure was observed between insular populations\nwith both nuclear microsatellites and the mitochondrial cytochrome c\noxidase subunit I. Moreover, deviations in the Hardy-Weinberg\nEquilibrium of insular populations suggests the exitance of archipelago\nspecific processes. The high dispersal ability of E. castanea combined\nwith the ephemeral nature of oceanic shallow-water sandy habitats likely\nmade each population to be composed of individuals from multiple\nsources. High prevalence of null alleles, gene duplication hint at the\npotential occurrence of recent polyploidization events that require\nfurther investigation. Moreover, we found evidence of hyperdiversity\namong the markers used which may constrain the detection of more\ndetailed patterns. We herewith demonstrate the uniqueness of insular\nenvironmental settings and inquire further into the evolutionary and\nbiogeographic patterns of marine shallow-water infaunal species from\nvolcanic oceanic islands.<\/jats:p>","DOI":"10.22541\/au.172815849.90487677\/v1","type":"posted-content","created":{"date-parts":[[2024,10,5]],"date-time":"2024-10-05T20:01:39Z","timestamp":1728158499000},"source":"Crossref","is-referenced-by-count":0,"title":["Population dynamics of Ervilia castanea (Montagu, 1803) hints at evolutionary processes shaping north-east Atlantic insular sandy habitats"],"prefix":"10.22541","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4391-0699","authenticated-orcid":true,"given":"Livia","family":"Sinigaglia","sequence":"first","affiliation":[{"name":"BOKU University"}]},{"given":"Antonio","family":"Murias","sequence":"additional","affiliation":[{"name":"CIBIO - Centro de Investiga\u00e7\u00e3o em Biodiversidade e Recursos Gen\u00e9ticos"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6696-2649","authenticated-orcid":true,"given":"Harald","family":"Meimberg","sequence":"additional","affiliation":[{"name":"Boku University"}]},{"given":"Manuel","family":"Curto","sequence":"additional","affiliation":[{"name":"BIOPOLIS"}]},{"given":"Sergio","family":"Avila","sequence":"additional","affiliation":[{"name":"CIBIO"}]},{"given":"Lara","family":"baptista","sequence":"additional","affiliation":[{"name":"Royal Netherlands Institute for Sea Research"}]},{"given":"Patricia","family":"Madeira","sequence":"additional","affiliation":[{"name":"CIBIO"}]},{"given":"Thapasya","family":"Vijayan","sequence":"additional","affiliation":[{"name":"BOKU"}]}],"member":"311","container-title":[],"original-title":[],"deposited":{"date-parts":[[2024,10,5]],"date-time":"2024-10-05T20:01:39Z","timestamp":1728158499000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.authorea.com\/users\/839829\/articles\/1230313-population-dynamics-of-ervilia-castanea-montagu-1803-hints-at-evolutionary-processes-shaping-north-east-atlantic-insular-sandy-habitats?commit=f5a259f7eb6d16e315db431b59892d7ed3bbba70"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,10,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.22541\/au.172815849.90487677\/v1","relation":{},"subject":[],"published":{"date-parts":[[2024,10,5]]},"subtype":"preprint"}}
