The phylogenetic component of cooperative breeding in perching birds: a commentary

Article Abstract:

The study of behavioral and ecological evolution in a phylogenetic context is an essential constituent of comparitive studies in evolutionary biology. The article by Edwards and Naeem demonstrates the interface between macroevolutionary and microevolutionary analysis. Among the rapidly growing number of historical ecological studies, this field of study is handicapped the lack of accurate phylogenetic hypotheses for several groups. In the absence of hypotheses, behavioral ecologists have to either study cooperative groups with phylogenetic systematics or investigate their ecological data based on trees reconstructed from phenograms. Edwards and Naeem have chosen the second method, and their article is seminal.

Comparative analyses of phylogenetic effects in the life-history patterns of iguanid reptiles

Article Abstract:

A method was devised to identify the variations in life history traits that are due to phylogenetic effects. First, the taxonomic level at which most of the variation is associated was evaluated by nested ANCOVAs. An intraclass correlation coefficient, which measures the differences among descendant taxa at any given level, was subsequently calculated. Finally, a network autocorrelation method was used to map the species' life history attributes onto their evolutionary relationships, thus showing variation patterns that are explainable in terms of phylogenetic interrelationships.

The phylogenetic component of cooperative breeding in perching birds

Article Abstract:

The study of avian cooperative breeding (CB) in a detailed phylogenetic context is presently decreasing in the study of this subject. The evolution and adaptive status of CB in the context of phylogenetic trees is studied utilizing the newer statistical and conceptual methods applicable for mutual relations among species existing in their phylogentic relationships. The phylogenetic studies of genera rich in cooperative breeders, in addition to biogeographical studies, help in the identification of the ecological conditions surrounding the origin of CB in various clades.
