The phylogenetic relationships of the Margarornis assemblage (Furnariidae)

Article Abstract:

A phylogenetic analysis of 10 species of birds was conducted to compare the hindlimb musculature of passerine 'treerunners,' collectively called the Margarornis assemblage, and the related group of Dendrocolaptinae. Certain synapomorphic differences found between hindlimb muscles of the two species have disproved the hypothesis that treerunners belong to the Dendrocolaptine group. Significant differences have also been found between the closely related species of Lochmias nematura and Margarornis squamiger, indicating that Lochmias does not belong to the treerunner group.

Phylogenetic patterns in Montane Troglodytes Wrens

Article Abstract:

Phylogenetic studies of wrens in Troglodytes and related genera have been undertaken. A new hypothesis of relationships for the group are suggested. The Winter Wren and the Timberline Wren are distant relations to the rest of Troglodytes, and a genus Nanus for the Winter Wren is proposed. Song evolution has involved convergent derivation or retention of primitive song types in distant lines.

The phylogenetic approach to avian life histories: An important complement to within-population studies

Article Abstract:

The phylogenetic approach to studying the evolution of avian life histories is reported, and its application to life history traits in swallows is described. The approach provides distinctive insights into the selective role of the environment on the evolution of life history traits.
