Recently experimental and theoretical ecologists have shown a renewed interest toward ratio--dependent models. Specific questions are raised by the occurrence of the paradox of enrichment in such systems. In the present study we investigate a recent eco--epidemiological model, with an underlying predator--prey demographics. Contrary to a widely accepted opinion, our extensive numerical simulations reveal that in the presence of infection the paradox of enrichment may also occur in ratio--dependent ecosystems.

Abstract
Recently experimental and theoretical ecologists have shown a renewed interest toward ratio--dependent models. Specific questions are raised by the occurrence of the paradox of enrichment in such systems. In the present study we investigate a recent eco--epidemiological model, with an underlying predator--prey demographics. Contrary to a widely accepted opinion, our extensive numerical simulations reveal that in the presence of infection the paradox of enrichment may also occur in ratio--dependent ecosystems.
