摘要: Highly mobile species that thrive in a wide range of habitats are expected to show little genetic differentiation across their range. A limited but growing number studies have revealed patterns broad-scale can and do emerge vagile, continuously distributed species. However, these complex often shaped by both historical ecological factors. Comprehensive surveys variation at broad scale high resolution useful for detecting cryptic spatial structure investigating the relative roles processes structuring widespread, highly In this study, we analysed 10 microsatellite loci from over 1900 samples collected full mule deer (Odocoileus hemionus), one most widely abundant all large mammal North America. Through individual- population-based analyses, found evidence three main lineages, corresponding ‘mule deer’ morphological type two ‘black-tailed type. Historical biogeographic events likely primary drivers divergence species; boundaries lineages correspond well with predictions based on Pleistocene glacial cycles, substructure within each lineage demonstrates island vicariance. geographic areas, including entire lineage, fit an isolation-by-distance pattern rather than discrete clusters. lack areas continental west indicates not resulted restrictions gene flow sufficient emerge. Our results important implications our understanding evolutionary mechanisms divergence, as taxonomy, conservation management.
