Distribution of resources in time and space, km.. Its high density of buffalo, about 20 individuals km., is also rare, and, until about 1987, its density of African elephant (6 km.) was exceptional (for details see Chapter 3). Manyara lies in the rift valley of northern Tanzania. In this so-called Eastern Rift or Gregory Rift a number of soda

Social organization of buffalo cows,om a distance since it depends on seeing testicles or penis in males. I define cows as ‘adult’ if they are 6 years or older, and as ‘subadult’ if they are 3–5 years old. I define ‘cows with dependent offspring’ as adult cows with calves or young juveniles at foot and ‘cows without dependent offsprin

Population dynamics, catastrophes and stability,nsidered often, but population regulation by disease has received considerably less attention. Indeed, disease can play a dramatic role, as is demonstrated by the effect of the myxomatosis virus on rabbits. Yet, these catastrophes are rare events and can be studied only occasionally in wild animal p

Competition for food,only increase in numbers if individuals of another species decrease in numbers. This strongly suggests that there is competition for food between the different herbivore species. The main grass consumers in the Manyara system are buffalo, elephant, wildebeest and zebra. The data on the feeding behav

,Patch selection: predators and grazing by ‘rule of thumb’,perhaps one of the most basic behaviorally mediated processes in an animal’s life’ (Leuthold 1977, p. 40; see also, for example, Hornocker 1970, Bergerud . 1983a, b), but proof for this assertion is scanty Few studies have dealt with the problem of how the effect of predation risk must be considered

The effects of ecology on social organization,as been propelled by this drive too. A few years ago, researchers interested in the behaviour of animals stressed its genetic basis. It was a time when the behavioural repertoire of a species was considered more or less programmed by the genome. For example, Mayr (1970) thought that behaviour was pr
