WebResults are presented confirming that among African savanna herbivores, population metabolism scales positively with body mass, and a hypothesis is presented to explain this, on the basis of patterns of habitat use. Large species generally occur at lower population densities than small species but, being larger, use more energy per individual. The balance … WebFigure 1.

Body Size, Diet, and Population Density of Neotropical Forest Mammals

WebA population consists of all the organisms of a given species that live in a particular area. The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
