Using parsimony to reconstruct ancestral character states on a phylogenetic tree has
become a popular method for testing ecological and evolutionary hypotheses. Despite its …

Females of some Old World primate taxa advertise their sexual receptivity with exaggerated
sexual swellings. Although a number of hypotheses have been proposed, the function of this …

Many evolutionary biologists are concerned with the tremendous amount of diversity of
species, and their phenotypes, that we can currently observe in nature, and one of the most …

Understanding global patterns of biodiversity change is crucial for conservation research,
policies and practices. However, for most ecosystems, the lack of systematically collected …

Climate change has led to major changes in the phenology (the timing of seasonal activities,
such as flowering) of some species but not others. The extent to which flowering-time …

The ability of plants to supply water to their leaves is intimately associated with survival.
Water supply to leaves depends on maintaining an intact water column in the xylem from the …

We conducted a comparative analysis to determine life history and ecological correlates of
pollen limitation among 224 species of animal-pollinated flowering plants. To test …

Our knowledge of the ecology of tropical rain-forest trees is limited, with detailed information
available for perhaps only a few hundred of the many thousand of species that occur. Yet a …

When making a comparison between two or more traits across taxa, the assumption of
phylogenetic independence must be tested. Empirically determining the validity of this …

We integrate climatic niche models and dated phylogenies to characterize the evolution of
climatic niches in Oenothera sections Anogra and Kleinia (Onagraceae), and from that we …
