Harris discusses the story behind the menu selection of species with a nonselective diet. Omnivores have a generalist diet governed by competitive pressures and resource availability. The degree of meat consumption by omnivores informs their trophic position within the community of sympatric species. To the extent that competition determines diet choice by omnivores, in regions experiencing declines in apex mammalian carnivores, which usually regulate ungulate prey populations, carnivory by omnivores may increase. In Ghana, preliminary evidence from stable isotope analysis suggested a trophic ascension in baboons (Papio spp) where populations of African lions (Panthera leo) have been extirpated (Ecological and conservation implications of mesopredator release.
