Abstract
We proceed now to look at a rather general model for the interaction of two biological species. Special cases of this model will represent Predator-Prey, Competitive and Mutualistic interactions. We will however be able to demonstrate a very general result for all such models. Specifically, we will show that the models almost never admit periodic (cyclic) solutions. This of course means that in terms of finding a model which describes an ecosystem which is known to behave in a cyclic manner, the model discussed below is not adequate.
