My research interests lie at the nexus of community ecology, macroecology, and biogeography. I am particularly interested in the mechanistic bases of broad-scale patterns in the structure and diversity of natural communities. While at NCEAS, I will explore spatial variation in bat, bird, and rodent communities in the New World using indices of diversity that are more resolved and incorporate information regarding not only richness and evenness but also the ecological and evolutionary attributes of species (e.g., functional, phylogenetic, and phenetic diversity). Moreover, I will evaluate how variation among communities along primary environmental gradients (e.g., temperature, productivity, heterogeneity) contributes to one of the most ubiquitous patterns describing the distribution and abundance of organisms-- the latitudinal gradient in diversity.
