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.

The factors that cause a tarantula population to increase from 500 to 800 spiders
will be very different from the factors that cause an endangered condor
population to decrease from 10 to 8 birds. Fortunately, all changes in population
size can ...
In this case, the growth rate of Ni is negative, and the population decreases. The
decrease is represented as a left-pointing horizontal arrow in the state space.
Finally, if we are at a point precisely on the isocline, N\ neither increases nor ...
In this case, the population should rise towards a stable equilibrium, continue to
decrease away from an unstable equilibrium, and remain in place (dN/dt = 0) for
a neutral equilibrium. For simple growth equations, we can also analyze stability
