Persistence in food chains with general interactions

Abstract Sufficient conditions for persistence in n-link food chain models with interaction functions gi are given: for gi nondecreasing and n = 3, and for gi positive in some compact interval to the right of zero and general n. The results generalize those for Lotka-Volterra type models. Necessary conditions for persistence are also given.
