Phylogenetic relationships of typical antbirds (Thamnophilidae) and test of incongruence based on Bayes factors.

ABSTRACT:

Background

The typical antbirds (Thamnophilidae) form a monophyletic and diverse family of suboscine passerines that inhabit neotropical forests. However, the phylogenetic relationships within this assemblage are poorly understood. Herein, we present a hypothesis of the generic relationships of this group based on Bayesian inference analyses of two nuclear introns and the mitochondrial cytochrome b gene. The level of phylogenetic congruence between the individual genes has been investigated utilizing Bayes factors. We also explore how changes in the substitution models affected the observed incongruence between partitions of our data set.

Results

The phylogenetic analysis supports both novel relationships, as well as traditional groupings. Among the more interesting novel re
