Ecological Applications offers a progressive examination of the way ecological theory can be applied to remedy the many problems confronting us. The text moves through the levels of individual organisms, populations, communities, and ecosystems, culminating with the macroecological scale of landscape, regional, and global issues. The book is designed to grab the reader's interest with real-life problems but also to instil an understanding of the fundamentals of ecology. Applications including species conservation, pest control, harvest management, biosecurity, restoration, and reserve design are explored in both terrestrial and aquatic settings. The focus is on ecological sustainability, but economic and sociopolitical dimensions related to the sustainable use of natural resources are also examined. Ecological Applications is a current and comprehensive guide to the theory and practice of ecology for students and practitioners alike.
