An essential guide to quantitative research methods in ecology and conservation biology, accessible for even the most math-averse student or professional.
Quantitative research techniques have become increasingly important in ecology and conservation biology, but the sheer breadth of methods that must be understood – from population modelling and probabilistic thinking to modern statistics, simulation, and data science – as well as a lack of computational or mathematics training, have hindered quantitative literacy in these fields. In this book, ecologist Justin Kitzes answers those challenges for students and practising scientists alike.
Requiring only basic algebra and the ability to use a spreadsheet, the Handbook of Quantitative Ecology is designed to provide a practical, intuitive, and integrated introduction to widely used quantitative methods. Kitzes builds each chapter around a specific ecological problem and arrives, step by step, at a general principle through the act of solving that problem. Grouped into five broad categories – difference equations, probability, matrix models, likelihood statistics, and other numerical methods – the book introduces basic concepts, starting with exponential and logistic growth, and helps readers to understand the field's more advanced subjects, such as permutation tests, stochastic optimization, and cellular automata. Complete with online solutions to all numerical problems, Kitzes's Handbook of Quantitative Ecology is an ideal coursebook for both undergraduate and graduate students of ecology, as well as a useful and necessary resource for mathematically out-of-practice scientists.

Justin Kitzes is an assistant professor of biological sciences at the University of Pittsburgh. He is co-editor of The Practice of Reproducible Research: Case Studies and Lessons from the Data-Intensive Sciences.
"A low-threshold, high-ceiling introduction. Kitzes's book will appeal to undergraduate and graduate students who wish to increase their quantitative understanding to be able to better engage with the literature (which has grown increasingly quantitative) and take the first step – a large leap, in fact – toward becoming practitioners of quantitative ecology."
– Andrew Rominger, University of Maine
"A stroke of genius. Kitzes does an excellent job of translating the properties of biological systems into mathematical models, using basic logic and without any advanced math. His approach is a powerful way to demystify these models and make them intuitive."
– Corlett Wolfe Wood, University of Pennsylvania
