The primary focus of the Losos Lab is on the behavioral and evolutionary ecology of lizards. Major questions concern how lizards interact with their environment and how lizard clades have diversified evolutionarily. Addressing such questions requires integration of behavioral, ecological, functional morphological, and phylogenetic studies. Wherever possible, we emphasize experimental approaches to ecological, behavioral and evolutionary questions. A major focus has been the evolutionary radiation of Caribbean Anolis lizards, but other lizard radiations are also being studied.
