Effects of Higher-order Interactions on Community Dynamics in Food Chain
For the study of the impacts of higher-order interactions on community dynamics in food chain,a simple food chain model was established in the study.The dynamic changes of species in different situations were simulated and compared using MATLAB software.The results show that the higher-order interaction of intraspe-cific and interspecific predation on the predator can inhibit the survival of the prey,which is not conducive to the coexistence of the prey and the predator;the high-order interaction of intraspecific and interspecific predation on prey can promote the survival of prey,which is conducive to the coexistence of prey and predator.
