Dr. Fuller’s research efforts focus on identifying factors affecting variation in
mammal density and distribution. Whether a species is recognized as endangered, a
nuisance, or harvestable, knowledge of its natural history and population ecology is
essential in order to predict or responsibly manage population change. In order to better
understand the mechanisms of this change, Dr. Fuller and his students capture, mark, and
monitor a variety of carnivores, ungulates, and smaller herbivores to document their
movements, habitat use, food habits, survival, reproduction, social behavior, and
density, then synthesize results from their own and other studies. They survey
populations through direct and indirect means (e.g., scats, tracks, calls, cameras) to
assess distribution and relative abundance, and also collaborate with colleagues to
investigate roles of disease, genetics, nutrition, morphology, and human activities in
population regulation and species conservation.
