Models of Plio-Pleistocene hominid behavioral ecology often emphasize competition with large carnivores. This paper describes competition between modern humans and large carnivores in rural Uganda, including active, confrontational scavenging of carnivore kills by humans and carnivore attacks on humans. Information gathered from Ugandan Game Department archives (1923-1994) reveals that twentiet...

Eleven cases of pyometra were diagnosed in a captive exotic felid collection over 3 yr in seven African lions (Panthera leo), two tigers (P. tigris), one liger (lion-tiger crossbreed), and one leopard (P. pardus). Clinical signs included anorexia, lethargy, vulvar discharge, and vomiting. Diagnosis was based on clinical signs, complete blood cell counts, plasma biochemistry and electrolyte valu...

Populations of large carnivores can persist in mountainous environments following extensive land use change and the conversion of suitable habitat for agriculture and human habitation in lower lying areas of their range. The significance of these populations is poorly understood, however, and little attention has focussed on why certain mountainous areas can hold high densities of large carnivo...

Some mammals distinguish between and respond appropriately to the alarm calls of other mammal and bird species. However, the ability of birds to distinguish between mammal alarm calls has not been investigated. Diana monkeys (Cercopithecus diana) produce different alarm calls to two predators: crowned eagles (Stephanoaetus coronatus) and leopards (Panthera pardus). Yellow-casqued hornbills (Cer...
