Importance of food quality for extinction

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.
