Genomic differentiation in an endemic Philippine genus (Aves: Sarcophanops) owing to geographical isolation on recently disassociated islands.

ABSTRACT: Phylogeographical studies of Philippine vertebrates have demonstrated that genetic variation is broadly partitioned by Pleistocene island aggregation. Contemporary island discontinuity is expected to influence genetic differentiation but remains relatively undocumented, perhaps because the current episode of island isolation started in relatively recent times. We investigated inter- and intra-island population structure in a Philippine endemic bird genus (Sarcophanops) to determine whether genetic differentiation has evolved during the recent period of isolation. We sequenced thousands of genome-wide restriction site associated DNA (RAD) markers from throughout the Mindanao group to assess fine-scale genetic structure across islands. Specifically, we investigated patterns of gene fl
