Effects of body size on the diurnal activity budgets of African browsing ruminants

We compared the diurnal activity budgets of four syntopic species of African browsing ruminant that differ widely in body size. These were concurrently studied through all phases of the seasonal cycle, in the same area, using the same methods. We tested five predictions from the literature on how body size is expected to influence the […]

Scaling of mammalian long bones: small and large mammals compared

Long bones from a taxonomically diverse assemblage of extant terrestrial mammals, spanning more than three orders of magnitude in body mass, have been measured in order to evaluate earlier models proposed for limb allometry as a means of physically coping with increased body size in large species. Linear regression models are unable to explain long […]

Cryptic Consumers and the Ecology of an African Savanna

East African savannas have fascinated generations of explorers, scientists, and the public. Nowhere else is there such a concentration and diversity of large, charismatic animals, and nowhere else is ecology portrayed so dramatically. Spectacular migrations of a million wildebeest tracking the rains dominate the Serengeti-Mara ecosystem of Tanzania and Kenya. Lions and hyenas pursue gazelle, […]
