Two Tickets to Paradise: Multiple Dispersal Events in the Founding of Hoary Bat Populations in Hawai'i

摘要: The Hawaiian islands are an extremely isolated oceanic archipelago, and their fauna has long served as models of dispersal in island biogeography. While molecular data have recently been applied to investigate the timing origin events for several animal groups including birds, insects, snails, these questions largely unaddressed Hawai'i’s only native terrestrial mammal, hoary bat, Lasiurus cinereus semotus. Here, we use test hypotheses that (1) L. c. semotus originated via from North American populations rather than South villosissimus, (2) modern were founded a single event. Contrary latter hypothesis, our mitochondrial support biogeographic history multiple, relatively recent dispersals bats America islands. Coalescent demographic analyses multilocus suggest no more 10 kya. Our finding multiple evolutionarily significant units Hawai'i highlights information should be useful re-evaluation conservation status Hawai'i.
