abstract = {? Western North America and Mexico contain a high density of conifer species. This diversity could be the product of the orographic and climate changes from the Oligocene onwards. In this study we focus on the evolutionary history of Juniperus blancoi, in order to determine the impact of climate change and environmental heterogeneity in population differentiation.
? We estimated population structure, phylogenetic relationships and historical demography of individuals from J. blancoi populations using nuclear genes. We correlated genetic structure with ecological differentiation, divergence times, and changes in population size.
? Populations of J. blancoi are differentiated into three groups that correspond to low, mid and high altitude populations. The three groups diversified in the Late-Miocene, Early-Pliocene, with only a few events of gene flow. Northern populations exhibit a pattern of population growth during the Pleistocene that could be linked to climate changes in Northern Mexico.
? Populations of J. blancoi have significant ecological differentiation and divergence dates, which correspond to periods of global cooling and mountain uplift during the Miocene. This suggests that mountain ranges in tropical and subtropical latitudes play an important role in the speciation and persistence of conifer taxa in diversity hotspots, by providing diverse environmental conditions.
