Introduction to Population Ecology is an accessible and up–to–date textbook covering all aspects of population ecology. Using botanical and zoological examples from the tropics to the tundra, this text discusses field and laboratory data to illustrate the fundamental laws of population ecology. Each chapter provides an overview of how population theory has developed, exploring single–species population growth and self–limitation, metapopulations, and a broad range of interspecific interactions including parasite–host, predator–prey, and plant–herbivore. Throughout, the mathematics is kept as simple as possible, using a careful step–by–step approach, and including graphs and other visual aids to help understanding.
