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). WebClimate change can alter the timing and availability of prey resources, with potential negative impacts on population dynamics. The authors used empirical data from prey selection and growth experiments as well as a bioenergetic model to examine the optimal foraging strategies of herring larvae under different temperature and prey size scenarios to better …
