This book contains more mathematical detail than many ecology textbooks, but avoids the jargon and mathematical terminology that can intimidate students. The book demystifies ecological models and the mathematics behind them, and includes both simple and advanced problems, followed by fully worked examples. It will sell us both a primary and supplementary textbook. This book 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.
