title: Data from: Paleo-drainage basin connectivity predicts evolutionary relationships across three southeast Asian biodiversity hotspots

description: Understanding factors driving diversity across biodiversity hotspots is
 critical for formulating conservation priorities in the face of ongoing
 and escalating environmental deterioration. While biodiversity hotspots
 encompass a small fraction of Earth’s land surface, more than half the
 world’s plants and two-thirds of terrestrial vertebrate species are
 endemic to these hotspots. Tropical Southeast Asia displays extraordinary
 species richness, encompassing four biodiversity hotspots, though
 disentangling multiple potential drivers of species richness is confounded
 by the region’s dynamic geological and climatic history. Here, we use
 multi-locus molecular genetic data from dense multi-species sampling of
 freshwater fishes across three biodiversity hotspots, to test the effect
 of Quaternary climate change and resulting drainage rearrangements on
 aquatic faunal diversification. While Cenozoic geological processes have
 clearly shaped evolutionary history in Southeast Asian halfbeak fishes, we
 show that paleo-drainage re-arrangements resulting from Quaternary climate
 change played a significant role in the spatiotemporal evolution of
 lowland aquatic taxa, and provides priorities for conservation efforts.
