An ecosystem''s complexity develops from the vast numbers of species interacting in ecological communities. The nature of these interactions, in turn, depends on environmental context. How do these components together influence an ecosystem''s behavior as a whole? Can ecologists resolve an ecosystem''s complexity in order to predict its response to disturbances? Resolving Ecosystem Complexity develops a framework for anticipating the ways environmental context determines the functioning of ecosystems. Oswald Schmitz addresses the critical questions of contemporary ecology: How should an ecosystem be conceptualized to blend its biotic and biophysical components? How should evolutionary ecological principles be used to derive an operational understanding of complex, adaptive ecosystems? How should the relationship between the functional biotic diversity of ecosystems and their properties be understood? Schmitz begins with the universal concept that ecosystems are comprised of species that consume resources and which are then resources for other consumers. From this, he deduces a fundamental rule or evolutionary ecological mechanism for explaining context dependency: individuals within a species trade off foraging gains against the risk of being consumed by predators. Through empirical examples, Schmitz illustrates how species use evolutionary ecological strategies to negotiate a predator-eat-predator world, and he suggests that the implications of species trade-offs are critical to making ecology a predictive science. Bridging the traditional divides between individuals, populations, and communities in ecology, Resolving Ecosystem Complexity builds a systematic foundation for thinking about natural systems.

How the science of ecology is changing to meet the daunting challenges of environmental sustainabilityOur species has transitioned from being one among millions on Earth to the species that is single-handedly transforming the entire planet to suit its own needs. In order to meet the daunting challenges of environmental sustainability in this epoch of human domination—known as the Anthropocene—ecologists have begun to think differently about the interdependencies between humans and the natural world. This concise and accessible book provides the best available introduction to what this new ecology is all about—and why it matters more than ever before.Oswald Schmitz describes how the science of ecology is evolving to provide a better understanding of how human agency is shaping the natural world, often in never-before-seen ways. The new ecology emphasizes the importance of conserving species diversity, because it can offer a portfolio of options to keep our ecosystems resilient in the face of environmental change. It envisions humans taking on new roles as thoughtful stewards of the environment to ensure that ecosystems have the enduring capacity to supply the environmental services on which our economic well-being—and our very existence—depend. It offers the ecological know-how to maintain and enhance our planet''s environmental performance and ecosystem production for the benefit of current and future generations.Informative and engaging, The New Ecology shows how today’s ecology can provide the insights we need to appreciate the crucial role we play in this era of unprecedented global environmental transition.
