A Primer of Ecology
A Primer of Ecology presents a concise but detailed exposition of the most common mathematical models in population and community ecology. It is intended to demystify ecological models and the mathematics behind them by deriving the models from first principles. The Primer explains in detail basic concepts of exponential and logistic population growth, age-structured demography, metapopulation dynamics, competition, predation, island biogeography, and, in a chapter new to this edition, succession. The book may be used as a self-teaching tutorial by students, as a primary textbook, or as a supplemental text to a general ecology textbook.

We can understand these equations much better by using the state-space graph,
a special kind of plot. In the state-space graph, the x axis represents the
abundance of species 1, and the y axis represents the abundance of species 2.
(a) (b) Figure 5.2 (a) A state-space graph. The axes of the state space are the
abundances of the two species (Ni and N2). As abundances change through time
, a curve is traced from left to right. The numbers on the curve indicate time, ...
An increase in Ni in the state space is represented as a horizontal arrow pointing
to the right. The arrow is horizontal because the abundance of species 1 is
represented on the x axis. When you work with state-space graphs, pay close ...
