This volume focuses on the integration of population and ecosystem ecology - an approach that offers vast potential for improving our understanding of the complexities of nature and the management of environmental problems. The editors have brought together a group of experts to explore diverse aspects of linking species and ecosystem perspectives - theoretical, empirical and pragmatic. These include: processes that range from a local to a planetary scale; the role of organisms as ecosystem engineers; the use of ecological flow chains to link population and ecosystem processes; numerous examples of the influence of species on ecosystem processes and vice versa; a unique blend of problems and processes drawn from marine; freshwater and terrestrial ecosystems; problems of species redundancy in ecosystem processes; stoichiometric constraints on species interactions; and scaling and aggregation problems. Linking Species and Ecosystems establishes conceptual frameworks for the rigorous study of interactions between species and ecosystems, it points to still-unanswered questions, and it identifies future research directions. Integration of ecology with its implications for teaching, research and society are central to the book. This volume should serve as a resource for ecology researchers, students, and environmental managers and should stimulate debate on the future integration of the field. This book should be of interest to ecologists - graduate students and established researchers; biology; zoology; ecology; evolutionary biology; integrative or organismal biology; entomology; plant science; forestry; wildlife management; and environmental studies.
