| novel patterns of historical isolation, dispersal, and secondary contact across baja california in the rosy boa (lichanura trivirgata). | mitochondrial dna (mtdna) sequence variation was examined in 131 individuals of the rosy boa (lichanura trivirgata) from across the species range in southwestern north america. bayesian inference and nested clade phylogeographic analyses (ncpa) were used to estimate relationships and infer evolutionary processes. these patterns were evaluated as they relate to previously hypothesized vicariant events and new insights are provided into the biogeographic and evolutionary processes important in baj ... | 2008 | 18248742 |
