Mathematical ecology is the application of mathematics to describe and
understand ecosystems. There are two main approaches. One is to describe
natural communities and induce statistical patterns or relationships
which should generally occur. However, this book is devoted entirely to
introducing the student to the second approach: to study deterministic
mathematical models and, on the basis of mathematical results on the
models, to look for the same patterns or relationships in nature. This
book is a compromise between three competing desiderata. It seeks to:
maximize the generality of the models; constrain the models to "behave"
realistically, that is, to exhibit stability and other features; and
minimize the difficulty of presentations of the models. The ultimate
goal of the book is to introduce the reader to the general mathematical
tools used in building realistic ecosystem models. Just such a model is
presented in Chapter Nine. The book should also serve as a
stepping-stone both to advanced mathematical works like Stability of
Biological Communities by Yu. M. Svirezhev and D. O. Logofet (Mir,
Moscow, 1983) and to advanced modeling texts like Freshwater Ecosystems
by M. Straskraba and A. H. Gnauch (Elsevier, Amsterdam, 1985).
