We have come to know that our ability to survive and grow as a nation to a very large degree depends upon our scientific progress. Moreover, it is not enough simply to keep 1 abreast of the rest of the world in scientific matters. We must maintain our leadership. President Harry Truman spoke those words in 1950, in the aftermath of World War II and in the midst of the Cold War. Indeed, the scientific and engineering leadership of the United States and its allies in the twentieth century played key roles in the successful outcomes of both World War II and the Cold War, sparing the world the twin horrors of fascism and totalitarian communism, and fueling the economic prosperity that followed. Today, as the United States and its allies once again find themselves at war, President Truman’s words ring as true as they did a half-century ago. The goal set out in the Truman Administration of maintaining leadership in science has remained the policy of the U. S. Government to this day: Dr. John Marburger, the Director of the Office of Science and Technology (OSTP) in the Executive Office of the President, made remarks to that effect during his 2 confirmation hearings in October 2001. The United States needs metrics for measuring its success in meeting this goal of maintaining leadership in science and technology. That is one of the reasons that the National Science Foundation (NSF) and many other agencies of the U. S.

This is a textbook for Natural Resource Management, Resource Conservation and Ecosystem Management, as well as other related or more specialized courses. Most textbooks on natural resource and ecosystem management are dominated by a steady-state view that interprets change as gradual and incremental and disregards interactions across scales. Management implementation of steady-state theory and policies tends to invest in controlling a few selected ecosystem processes, at the expense of long-term social-ecological resilience - i.e., the capacity of the system to cope with surprise and abrupt changes. Loss of resilience makes systems more vulnerable to both expected and unforeseen changes. Achieving desirable outcomes for humanity, such as those of the UN Millennium Development Goals on poverty, food security, and environmental sustainability, will require new integrated and adaptive approaches to social and economic development, where the complex interconnectedness between humans and nature, at all scales, is considered and the existence of uncertainty and surprise accepted as the rule.The purpose of this textbook is to provide a new framework for resource management - a framework based on the necessity of managing resources in a world dominated by uncertainty and change.The book links recent advances in the theory of resilience, sustainability, and vulnerability with practical issues of resource management.

Ecosystem ecology sees living organisms, including people and the elements of their environment, as part of a single integrated system. The comprehensive coverage in this textbook examines the central processes at work, including their freshwater components.

Ecosystem ecology regards living organisms, including people, and the elements of their environment as components of a single integrated system. The comprehensive coverage in this textbook examines the central processes at work in terrestrial ecosystems, including their freshwater components. It traces the flow of energy, water, carbon, and nutrients from their abiotic origins to their cycles through plants, animals, and decomposer organisms. As well as detailing the processes themselves, the book goes further to integrate them at various scales of magnitude—those of the ecosystem, the wider landscape and the globe. It synthesizes recent advances in ecology with established and emerging ecosystem theory to offer a wide-ranging survey of ecosystem patterns and processes in our terrestrial environment.Featuring review questions at the end of each chapter, suggestions for further reading, and a glossary of ecological terms, Principles of Terrestrial Ecosystem Ecology is a vitally relevant text suitable for study in all courses in ecosystem ecology. Resource managers and researchers in many fields will welcome its thorough presentation of ecosystem essentials.
