Vertebrate Ecology, Behavior, Comparative Physiology, Evolutionary Biology, Ecological Energetics
Dr. Weigl’s interests include the fields of ecology, behavior, comparative physiology and evolutionary biology. Most of Dr. Weigl’s research and that of his students involves wild vertebrates, combines field and laboratory approaches and concentrates on energetic aspects of adaptations to different environments. In the past few years his work has included foraging behavior in squirrels, investigations of endangered species of mammals, locomotion in frogs, thermoregulation in screech owls, parasite-mediated competition in flying squirrels, the coevolutionary relationships of tree squirrels and certain species of conifers and fungi, the biomechanics of the hind limbs and talons of hawks and owls, and the possible role of megaherbivores in maintaining grassland habitats.
