The Mammals,s, are the only group having a constant body temperature, i.e. are homeothermic. This makes them more independent of environmental conditions, notably high and low temperatures, than is the case for those animals unable to regulate their body temperature (poikilotherms, which comprise the vast major

Populations, the individual mammal is a recognizable and easily defined unit. By studying populations it is possible to record changes in densities and to quantify the effects of different factors on its numbers. Obviously, densities can vary enormously—for example, in Serengeti, there is one cheetah (.) to eve

Energetics, requirements and the number of animals present. For present purposes it is convenient first to consider how energy is utilized by the individual (i.e. its energy budget), and then how populations of mammals influence and make use of the energy resources available to them. While this chapter restric
