dc.description.abstract One of the most persistent challenges in biology is explaining the distribution of animal taxa. Quantitative explanations for the distribution of organisms are challenged by the complexity of factors that potentially limit a species range, including topography, ecology, climate and biology. Because of limits on data and approaches, early biogeographers were hampered in their ability to explain patterns. Here, I benefit from two primary developments in biogeography. My research draws from the accumulation of data across several scientific disciplines and advances in spatial and statistical approaches to examine the distribution of animal taxa within an integrative biogeography framework. I combine ecological, climatic and genetic data and analyses to address these primary issues with biogeographical distributions: 1, reconstructing the colonization history of taxa, 2, distinguishing between Pleistocene source and Pleistocene refugial populations, 3, understanding how distribution constraints influence population connectivity and the evolutionary potential of species populations and 4, modeling the ecological and genetic parameters that most influence the extirpation of local populations. en_US
