Relations between structure of biological communities and ecosystem functions determined by interactions of predation and competition

I studied relations between biodiversity, ecosystem function and stability, employing mathematical models. I have obtained the following results ; the higher number of herbivore species and the more intense competition among plants may enhance plant diversity ; heterogeneous spatial structure of a habitat may relax indirect competition ; relative efficiency between indirect and direct energy paths from the producer to the omnivore controls dynamics of a food web including omnivores ; a primary factor of irruptive increase in a herbivore population is competition among plants, and predators stabilize a community composed of herbivores and plants.
