Population Growth in a Time-Varying Environment,process. Unfortunately, the mathematical characterizations of many realistic sorts of fluctuations are very difficult; even some conceptually simple models lead to results which are still disputed by biological researchers. To gain some insight, let us look at the simplest possible model, and see what can be learned.

Quadratic Two-Species Population Models,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.

On account of its origin as lecture notes, some sections of the text are telegraphic in style while other portions are overly detailed. This stylistic foible has not been modified as it does not appear to detract seriously from the re
