Phenotypic evolution of an Atlantic Forest passerine (Xiphorhynchus fuscus): Biogeographic and systematic implications
We studied the phenotypic variation of the Atlantic Forest passerine Xiphorhynchus fuscus (Aves: Dendrocolaptidae) with the broad aim of addressing whether the history and type of forest affected the evolution of endemic taxa. We also tested whether the different subspecies and genetic lineages of X...
