abstract = {Numerous hypotheses have been proposed for the historical processes governing the rich endemism of Madagascar?s biodiversity. The watershed model of Wilm?, Goodman & Ganzhorn (2006) suggests that drier climates in the recent geological past resulted in the contraction of forests around major watersheds, thereby defining areas of endemism. We test whether this hypothesis explains phylogeographic patterns in a dry forest-dependent rodent, Eliurus myoxinus, an endemic species widely distributed through western Madagascar. We sequenced the mitochondrial cytochrome b locus and nuclear introns of the β-fibrinogen and the growth hormone receptor genes for E. myoxinus. Using a parametric bootstrapping approach, we tested whether the mitochondrial gene tree fit expectations of local differentiation given the watershed model. We additionally estimated population differentiation, historical demographic parameters and reconstructed the spatial history of E. myoxinus to highlight spatial and temporal patterns of differentiation. The data do not support the watershed model as a clear explanation for the genetic patterns of diversity within extant E. myoxinus populations. We find striking patterns of latitudinal genetic structure within western Madagascar, and indicate possible roles for environmental and ecological gradients along this axis in generating phylogeographic diversity.}
