Abstract

Nutrient enrichment has a great influence on the stability of producer species. However, in the presence of predators, its influence has not yet been studied. In this research, we build a food web model which coupled a classic nutrient competition model with a bio-energetic predator-prey model, and a trade-off between competitive abilities of producers is considered.We considered the generalist predation and explored the effect of nutrient enrichment on the stability of producer species under the pressure of predation. The results showed increasing with the nutrient supplement, the biomass of the producers increased and the stability of producer was broken. It turned out that eutrophication destroyed the stability of producer species. Results in this research will be helpful in understanding the influence of nutrient enrichment under the pressure of predation and providing theoretical guidance for ecosystem and biodiversity conservation.
