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).

Webthat body size is a useful predictor of the nature (i.e., extrinsic/intrinsic) of population regulation in mam-mals. Our objectives were to determine if patterns of temporal variability in mammal populations varied with body size, and if so, to evaluate whether the differences were consistent with Caughley and Krebs's WebOverall, there is a negative relationship between body mass and population density (i.e. larger species tend to have lower population densities) and this is a reflection of the …
