Testing diversification models of endemic Philippine forest mice (Apomys) with nuclear phylogenies across elevational gradients reveals repeated colonization of isolated mountain ranges

摘要

AimOur aims were to document the extent of diversification in an endemic clade of small mammals (Apomys, subgenus Megapomys) on a large oceanic island and to test whether speciation occurred primarily (1) along isolated elevational gradients or (2) among montane areas, as would be expected if diversification were driven by glacial cycles.
