The recent inclusion of genomic data into phylogeographic studies has dramatically improved our understanding in organisms where evolutionary relationships have been challenging to infer. We used whole-genome sequences to study the phylogeography of the intertidal snail Littorina saxatilis, which has successfully colonized and diversified across a broad range of coastal environments in the Northern Hemisphere amid repeated cycles of glaciation. Building on past studies based on short DNA sequences, we used genome-wide data to provide a clearer picture of the relationships among samples spanning most of the species natural range. Our results confirm the trans-Atlantic colonization of North America from Europe, and have allowed us to identify rough locations of glacial refugia and to infer likely routes of colonization within Europe. We also investigated the signals in different datasets to account for the effects of genomic architecture and non-neutral evolution, which provides new insights about diversification of four ecotypes of L. saxatilis (the crab, wave, barnacle, and brackish ecotypes) at different spatial scales. Overall, we provide a much clearer picture of the biogeography of L. saxatilis, providing a foundation for more detailed phylogenomic and demographic studies. https://research-explorer.ista.ac.at/download/14833/14875/2023_EvolJourLinneanSociety_Stankowski.pdf application/pdfno https://creativecommons.org/licenses/by-nc/4.0/ Oxford University Press2023 eng 2752-938X10.1093/evolinnean/kzad002 21 Stankowski, Sean, Zuzanna B Zagrodzka, Juan Galindo, Mauricio Montaño-Rendón, Rui Faria, Natalia Mikhailova, April M H Blakeslee, et al. “Whole-Genome Phylogeography of the Intertidal Snail Littorina Saxatilis.” <i>Evolutionary Journal of the Linnean Society</i>.
