New textbook, aiming to be an accessible and up-to-date textbook covering all aspects of population ecology.
Coverage includes: discussion of field and laboratory data to illustrate the fundamental laws of population ecology; overview of how population theory has developed; explores single-species population growth and self-limitation; metapopulations; and a broad range of interspecific interactions including parasite-host, predator-prey, and plant-herbivore.
Aims to keep the mathematics as simple as possible, using a careful step-by-step approach and including graphs and other visual aids to help understanding.

Larry L. Rockwood is Associate Professor of Environmental Science and Policy at George Mason University, Virginia. He received his B.S. degree in Biopsychology from the University of Chicago, where he also completed his doctoral research on the foraging patterns of leaf-cutting ants. He has taught courses in population ecology for 30 years.
"Budding ecologists will be enthused by possibilities amongst the wealth of empirical studies that Rockwood draws on to inform our conceptual understanding of population ecology [...] This is a most satisfyingly accessible study guide for all students with a serious commitment to population ecology, and an essential reference for any researchers and teachers interested in the interactions of populations with their environments."
- Environmental Conservation
"This is refreshing because so many population biology books seem content to dwell upon the mathematical satisfaction that can be derived from elegant models. Some of Rockwell's chapters, such as the one on metapopulations, send the reader to a selection of case studies illustrating the application of a particular concept or model. This enables the student to compare theory with actuality and thereby assess the theory more critically. In this respect, it is truly a text of population ecology rather than just population biology."
- Bulletin of the British Ecological Society
"Introduction of Population Ecology is an accessible and up-to-date textbook covering all aspects of population ecology [...] This text is an essential introduction to population ecology, including those with little mathematical experience."
- Biotechnology, Agronomy, Society and Environment
"This is an eminently readable text ideal for a University audience and would not be out of place in a school library to extend able students."
- Journal of Biological Education
"Written clearly and succinctly for beginners, [this] exciting and well-presented book also has practical implications for policy makers, conservationists [...] and stewards of the natural habitat."
- Northeastern Naturalist
