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

摘要: The population densities of Neotropical mammalian species are predictably related to their body masses and diets. In interspecific comparisons, generally declined with increasing mass, mass within each seven specified dietary categories. our regression analyses, alone accounted for approximately half the variation in density general case, a greater proportion five regressions Pairwise comparisons using stepwise multiple indicated that adding diet as well significantly increased variance explained. Finally, magnitude effect on varied class. These results indicate that, general, larger-bodied occur at lower than smaller-bodied species, restricted diets those higher trophic levels whose allows t...
