Biodiversity can be boosted by colonization of new habitats, such as different continents and remote islands. Molecular studies have suggested that recently evolved organisms probably colonized already separated continents by dispersal, either via land bridge connections or crossing the ocean. Here we test the on-land and trans-marine dispersal hypotheses by evaluating possibilities of colonization routes over Bering land bridge and across the Atlantic Ocean in the cosmopolitan bat genus Eptesicus (Chiroptera, Vespertilionidae). Previous molecular studies have found New World Eptesicus more closely related to Histiotus, a Neotropical endemic lineage with enlarged ears, than to Old World Eptesicus. However, phylogenetic relationships within the New World group remained unresolved and their evolutionary history was unclear. Here we studied the systematics of New World Eptesicus and Histiotus using extensive taxonomic and geographic sampling, and genomic data from thousands of ultra-conserved elements (UCEs). ... : These data sets were generated from target sequencing of 5k Tetrapod UCEs (Faircloth et al. 2012. Ultraconserved Elements Anchor Thousands of Genetic Markers Spanning Multiple Evolutionary Timescales. Systematic Biology, 61(5), 717–726. https://doi.org/10.1093/SYSBIO/SYS004 ). Methodology details are provide in the paper. Samples are named by species identities (from source collections) and/or sample IDs that are given in the publication supplementary Table S1.
