Trophic species

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A trophic species is a group of species that are aggregated according to their common trophic (feeding) positions in a food web or food chain. Trophic species have identical prey and a shared set of predators in the food web. This means that members of a trophic species share many of the same kinds of ecological functions.[1][2] The trophic species concept is similar to the concept of an ecological guild, but the latter focuses on how resources are used through common adaptations to similar problems.[3]
