I am an Integrative Evolutionary Ecologist, meaning that my research addresses a range of fundamental questions in Ecology and Evolutionary Biology from a multi-disciplinary, integrative perspective and using a diverse array of tools including field experiments, phylogenetically-rooted comparative statistical analyses, quantitative estimates of physiological performance, experimental analyses of reproductive behavior, and molecular genetics. I often work at the nexus of typically disparate fields of study, for example combining genetic, phylogenetic, physiological and macroecological perspectives in a single analysis of distribution and dispersal (Bernardo et al. 2007). Because multiple causality is inherent in understanding ecological and evolutionary problems, my research emphasizes a strong inference approach that therefore relies on both large datasets and multivariate statistical models to evaluate competing hypotheses. Most of my active work involves vertebrates and insects and other major invertebrate groups.
General areas of interest include: o determinants of range size and position o biodiversity conservation in the face of climate change o detection, and ecological and conservation implications of cryptic speciation and diversity o vertebrate ecology and life history o biology of amphibians and reptiles, especially salamanders and lizards o speciation and evolution of reproductive isolation o evolutionary ecology of body size including its role in species packing and community assembly o clinal variation in life history and physiological traits o comparative animal physiology and physiological ecology especially as they relate to life history variation and range occupation (macrophysiology) o life history evolution o evolution and implications of maternal effects, especially propagule size o experimental ecology
