As one of the most quantitative of ecological subdisciplines, resource competition is an important, central area of ecology. Research into this area has increased and resource competition models have become more complex. The characterization of this phenomenon is therefore the aim of this book. It seeks to identify the unifying principles emerging from experimental and theoretical approaches as well as the differences between organisms, illustrating that greater knowledge of resource competition will benefit human and environmental welfare. The book should be of interest to students and researchers in population biology, community ecology, mathematical biology, and environmental management/engineering.
