Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …

We used phylogenetic analyses of cytochrome b sequences of malaria parasites and their
avian hosts to assess the coevolutionary relationships between host and parasite lineages …

Recent analyses suggest that a few major shifts in diversification rate may be enough to
explain most of the disparity in diversity among vertebrate lineages. At least one significant …

Summary 1 It has been suggested that immune defences are shaped by life history and
ecology, but few general patterns have been described across species. We hypothesized …

This paper summarizes and discusses the many new insights into passerine evolution
gained from an increased general interest in avian evolution among biologists, and …

Passerida is a monophyletic group of oscine passerines that includes almost 3500 species
(about 36%) of all bird species in the world. The current understanding of higher-level …

The theory of sexual selection predicts a relationship between male sexual traits and
reproductive success. This prediction has been tested extensively using the complexity of …

To understand interspecific patterns in the strength of sexual selection, variation in the costs
and benefits of exercising mate choice needs to be evaluated. One manifestation of sexual …

Systematic studies of Fringillidae have long been problematic due to their apparent recent
and explosive diversification. We present phylogenetic hypotheses of 44 fringillids that …

Antioxidants play an important role in protecting tissues against aging-associated oxidative
damage and are thus prime candidates for relating physiological mechanisms to variation in …
