The influence of the complex topography and dynamic history of the montane Neotropics on the evolutionary differentiation of a cloud forest bird (Premnoplex brunnescens, Furnariidae)

摘要: Aim To examine the effect of geographical barriers and habitat dynamics related to climatic oscillations on the phylogeography of a widespread passerine of Neotropical cloud forests, the spotted barbtail (Premnoplex brunnescens). Location Neotropical humid forests of montane areas in lower Central America and South America. Methods We sequenced two mitochondrial genes and one nuclear intron from specimens collected across the distribution of P. brunnescens. Phylogenetic relationships were inferred using Bayesian and maximum‐likelihood methods. Groups with maximum differentiation were estimated with spatial analysis of molecular variance (SAMOVA). We estimated timing of differentiation and relationships among groups with a species‐tree approach and historical demography with extended Bayesian skyline plots. Results Six highly differentiated clades of P. brunnescens are distributed in …
