Originally published in 1990, this text focuses on a comparison of the feeding ecology and social systems of the brown and spotted hyenas. Set in the semi-arid region of the Kalahari, the book examines roles and interactions of the two species in this finely balanced ecosystem and highlights the factors and mechanisms responsible for regulating the populations.
