| geographic isolation drives divergence of uncorrelated genetic and song variation in the ruddy-capped nightingale-thrush (catharus frantzii; aves: turdidae). | montane barriers influence the evolutionary history of lineages by promoting isolation of populations. the effects of these historical processes are evident in patterns of differentiation among extant populations, which are often expressed as genetic and behavioral variation between populations. we investigated the effects of geographic barriers on the evolutionary history of a mesoamerican bird by studying patterns of genetic and vocal variation in the ruddy-capped nightingale-thrush (turdidae: ... | 2016 | 26302950 |
