WebJun 6, 2006 · Density dependence in growth, body size, and mass has long been recognized in populations of large mammals (Fowler 1987). Population density can influence body size through a decrease in quantity or quality of food and a resulting increase in intraspecific competition (Clutton-Brock et al. 1982). WebDec 28, 2016 · Accordingly, the scaling between body mass and home range size should be comparable to the body mass scaling of forage intake rate of approximately 0.75 at the logarithmic scale [33,47,48]. On an arithmetic scale, this means that the positive relationship between home range size and body mass is steeper at smaller body masses, and …
Web3. Within each dietary category, the population densities of species decline with increasing body mass. This prediction does not repeat prediction 1; rather, it demonstrates the effect of body mass on population density because diet and body mass co-vary (Clutton-Brock and Harvey 1977, 1983).
