Baboons of the amboseli basin: Demographic stability and change

A cross-sectional demographic analysis of the entire baboon population of the Amboseli basin of southern Kenya was undertaken to complement the lon-gitudinal, intensive studies of a subpopulation. The present survey documented the extent and persistence of the influx of anubis baboons into the predominantly cynocephalus community and provided another example of the nonrandom dispersal patterns of cercopithecine males. In addition, the survey confirmed continued demographic stability of the basinwide baboon population and even growth in groups that had access to better feeding conditions, despite decline of the baboons' preferred habitat and expansion of human activities into wildlife areas. Conflicts with activities of humans, however, indicate that the present well-being of the Amboseli baboon population may be short-lived.
