We investigated divergence, gene flow, and speciation in Beringia, a region at the top of the North Pacific Ocean with a history of dramatic landscape alteration through Pleistocene glacial cycles. These cycles repeatedly split and connected the Asian and North American continents, separating and reconnecting avian populations. Glacial refugia within Beringia also isolated some populations for a time before potentially enabling them to reunite during interglacial periods. Prior work suggests gene flow plays an important role in the divergence of Beringian birds. To improve our understanding of the generation of avian diversity in Beringia, we tested models of demographic history in 11 lineages from five avian orders (Anseriformes, Gaviiformes, Charadriiformes, Piciformes and Passeriformes) using population\u2010, subspecies\u2010 and species\u2010level pairwise comparisons. We sequenced an average of 3710 ultraconserved element (UCE) loci from the nuclear genomes of these taxa to examine genetic differentiation and test models of divergence through diffusion analysis for demographic inference (\u03b4a\u03b4i). All of the inferred best\u2010fit models of divergence included gene flow. Together with prior work, this corroborates that divergence with gene flow is the predominant mode of divergence and speciation in Beringian birds.<\/jats:p>","DOI":"10.1111\/mec.70056","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T14:04:09Z","timestamp":1753711449000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Gene Flow Accompanies Divergence in Beringian Birds"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0903-2840","authenticated-orcid":false,"given":"Caitlyn C.","family":"Oliver Brown","sequence":"first","affiliation":[{"name":"Department of Biology and Wildlife University of Alaska Fairbanks  Fairbanks Alaska USA"},{"name":"University of Alaska Museum University of Alaska Fairbanks  Fairbanks Alaska USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7725-3637","authenticated-orcid":false,"given":"Travis C.","family":"Glenn","sequence":"additional","affiliation":[{"name":"Department of Environmental Health Science and Institute of Bioinformatics University of Georgia  Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8985-8104","authenticated-orcid":false,"given":"Kevin","family":"Winker","sequence":"additional","affiliation":[{"name":"Department of Biology and Wildlife University of Alaska Fairbanks  Fairbanks Alaska USA"},{"name":"University of Alaska Museum University of Alaska Fairbanks  Fairbanks Alaska USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,28]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/gkw343"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1474\u2010919X.2011.01116.x"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1089\/cmb.2012.0021"},{"key":"e_1_2_9_5_1","doi-asserted-by":"crossref","unstructured":"Boarman W.
