Much of Mongolia’s rangelands are under state control and managed via traditional land use practices and are habitat for numerous wildlife species harvested for their meat and fur. Political and economic transformations that have been occurring since the early 1990’s continues to aff ect all aspects of Mongolian society. To cope during periods of economic hardship, many turned to harvesting wil...

Occasionally, a grazing gazelle notices the approach of a predatory lion. Rather than immediately taking ight at top speed, she often jumps high in the air several times before eeing. Perhaps these \stots" are warnings to close-by, possibly related, gazelles? If this is the case why is the warning so energetic? Surely evolution would favor less exhausting signals, since exhaustion is to be avoi...

1. Theory predicts that small grazers are regulated by the digestive quality of grass, while large grazers extract sufficient nutrients from low-quality forage and are regulated by its abundance instead. In addition, predation potentially affects populations of small grazers more than large grazers, because predators have difficulty capturing and handling large prey. 2. We analyse the spatial d...

Data are presented on the demography and reproductive success of cheetahs (Acinonyx jubatus) living on the Serengeti Plains, Tanzania over a 25-year period. Average age at independence was 17.1 months, females gave birth to their ®rst litter at approximately 2.4 years old, interbirth interval was 20.1 months, and average litter size at independence was 2.1 cubs. Females who survived to independ...

THANKS TO Robert Ardrey's colorful description in his "Territorial Imperative," the territorial behavior of the Uganda Kob, Adenota kob thomasi (Sclater 1896), on traditional breeding grounds (TGs), or leks, is now fairly well known. It was my wife, Jimmie, who suggested to me, while on a field trip in Murchison Falls National Park in March 1957, the seemingly absurd idea that we were observing...

Title of Document: ANIMAL DISTRIBUTIONS AND MOVEMENT BEHAVIORS IN RELATION TO RESOURCE DYNAMICS Thomas Mueller, Ph.D., 2008 Directed By: Professor William F. Fagan Department of Biology Animal movements, whether spatially constrained or spread across broad spatial scales, are often motivated by a need for resources. This thesis seeks to explore the role spatial and temporal resource dynamics ma...

Wildlife conservation is facing numerous and mounting challenges on private and communal lands in Africa, including in Kenya. We analyze the population dynamics of 44 common wildlife species in relation to rainfall variation in the Nakuru Wildlife Conservancy (NWC), located in the Nakuru-Naivasha region of Kenya, based on ground total counts carried out twice each year from March 1996 to May 20...
