New cover image for Behavioral Ecology and Sociobiology

Starting with the January issue, BES has a new cover image showing Carter, an adult male chimpanzee (Pan troglodytes) of the Ngogo community in Kibale National Park, Uganda. Male chimpanzees exhibit higher body temperatures when associating with sexually receptive females, which may reflect the metabolic correlates of sexual behavior.
