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.

It has a ready biological interpretation as the carrying capacity of the environment

RANDOM VARIATION IN CARRYING CAPACITY In our analysis of
environmental stochasticity (Chapter 1), we assumed that resources were
unlimited, but that r varied randomly with time. For the logistic model, we will now
assume that r is ...
