Importance of food quality for extinction

Submitted by editor on 23 May 2017.Get the paper!

In communities of competing prey species of different food quality, predators may supplement their diets of low-quality prey with high-quality prey, leading to indirect interactions between different prey species. We show that this interaction not only ensures the persistence of low-quality prey but also promotes coexistence of low- and high-quality prey. Our research contributes to the understanding of cyanobacterial blooms, where low-quality prey dominates but may be kept from complete take-over by high-quality competitors.
