Predator–prey size relationships in an African large-mammal food web - Owen-Smith - 2007 - Journal of Animal Ecology - Wiley Online Library
Predator–prey size relationships in an African large-mammal food web - Owen-Smith - 2007 - Journal of Animal Ecology - Wiley Online Library: "Size relationships are central in structuring trophic linkages within food webs, leading to suggestions that the dietary niche of smaller carnivores is nested within that of larger species. However, past analyses have not taken into account the differing selection shown by carnivores for specific size ranges of prey, nor the extent to which the greater carcass mass of larger prey outweighs the greater numerical representation of smaller prey species in the predator diet. Furthermore, the top-down impact that predation has on prey abundance cannot be assessed simply in terms of the number of predator species involved."
