Research Council established the Ecosystems Panel in response to a request from the United States Global Change Research Program (USGCRP). The panel's charge included periodic reviews of the ecosystems aspects of the USGCRP, and this is the first of those reviews. It is based on information provided by the USGCRP, including Our Changing Planet (NSTC 1997 and earlier editions 1); ideas and conversations provided by participants in a workshop held in St. Michaels, Maryland, in July 1998; and the deliberations of the panel. In addition, the panel reviewed the ecosystems chapter of the NRC report Global Environmental Change: Research Pathways for the Next Decade (NRC 1999a, known as the Pathways report). The USGCRP is an interagency program established in 1989 and codified by the Global Change Research Act of 1990 (PL 101-606). The USGCRP comprises representatives of the departments of Agriculture, Commerce (National Oceanic and Atmospheric Administration and National Institute of Standards and Technology), Defense, Energy, Health and Human Services (the National Institute of Environmental Health Sciences), Interior, and State, as well as the Environmental Protection Agency, the National Aeronautics and Space Administration, the National Science Foundation, the Smithsonian Institution, the Office of Science and Technology Policy, the Office of Management and Budget, and the intelligence community (NSTC 1997). The USGCRP's research program is described in detail in Our Changing Planet (NSTC 1997, 1999). In brief, the program focuses on four major areas of earth-system science: 1) Seasonal to interannual climate variability; 2) Climate change over decades to centuries; 3) Changes in ozone, ultraviolet (UV) radiation, and atmospheric chemistry, and 4) Changes in land cover and in terrestrial and aquatic ecosystems. The fourth topic is the area in which advice was requested from the ecosystems panel. The Ecosystems Panel's charge has three parts: to provide a forum for the discussion of questions of ecosystem science of interest to scientists in and out of the federal agencies, to periodically review the ecosystem aspects of the USGCRP's research program, and to help identify general areas of ecosystem science that need additional attention, especially areas that cut across ecosystems and levels of ecological organization. In addressing the second item of its charge for this report, the panel first identified the most significant and challenging areas in ecosystem science, then used that identification as a basis to make recommendations to the USGCRP. Thus, this report is not a detailed review of the USGCRP's program, but rather an attempt to identify those areas that the panel concludes are most in need of attention by a general research program on global change. As noted in this report, some of those areas are already receiving attention by the USGCRP.

This major new book presents a collection of essays by leading authorities who address the current state of knowledge. The chapters bring together the early results of an international scientific research program designed to address what will happen to our ability to produce food and fiber, and what effects there will be on biological diversity under rapid environmental change. This book addresses how these changes to terrestrial ecosystems will feed back to further environmental change. International in scope, this state-of-the-art assessment will interest policymakers, students and scientists interested in global change, climate change and biodiversity. Special features include descriptions of a dynamic global vegetation model, developing generic crop models and a special section on the emerging discipline of global ecology.

Human-driven greenhouse emissions are increasing the velocity of climate change and the frequency and intensity of climate extremes far above historical levels. These changes, along with other human-perturbations, are setting the conditions for more rapid and abrupt ecosystem dynamics and collapse. This book presents new evidence on the rapid emergence of ecosystem collapse in response to the progression of anthropogenic climate change dynamics that are expected to intensify as the climate continues to warm. Discussing implications for biodiversity conservation, the chapters provide examples of such dynamics globally covering polar and boreal ecosystems, temperate and semi-arid ecosystems, as well as tropical and temperate coastal ecosystems. Given its scope, the volume appeals to scientists in the fields of general ecology, terrestrial and coastal ecology, climate change impacts, and biodiversity conservation.

Over 100 authors present 25 contributions on the impacts of global change on terrestrial ecosystems including: key processes of the earth system such as the CO2 fertilization effect, shifts in disturbances and biome distribution, the saturation of the terrestrial carbon sink, and changes in functional biodiversity, ecosystem services such the production of wheat, pest control, and carbon storage in croplands, and sensitive regions in the world threaten by rapid changes in climate and land use such as high latitudes ecosystems, tropical forest in Southeast Asia, and ecosystems dominated by Monsoon climate. The book also explores new research developments on spatial thresholds and nonlinearities, the key role of urban development in global biogeochemical processes, and the integration of natural and social sciences to address complex problems of the human-environment system.

The book brings together research topics having a broad focus on human and climate change impacts on the terrestrial ecosystems in the tropics in general and more specifically from the most significant and vulnerable Himalayan ecosystem. A total of 16 contributions included in the book cover a diverse range of global change themes such as the impacts of changing temperature and precipitation on soil ecosystems, forest degradation, extent and impacts of invasive species, plant responses to pollution, climate change impacts on biodiversity and tree phenology, environmental changes associated with land use, importance of traditional knowledge in climate change adaptation, timberline ecosystems, and role of integrated landscape modeling for sustainable management of natural resources. The book is a collective endeavour of an international multidisciplinary group of scientists focused on improving our understanding of the impacts of global change on the structure and functioning of tropical ecosystems and addressing the challenges of their future sustainable management. We hope that the book will help researchers working in the areas of ecology and environmental science to update their knowledge. We also expect that natural resource managers and policy planners will find explanations for some of their observations and hypotheses on multiple global change factors impacting tropical ecosystems and especially Himalayan ecosystems.

Global climate change is a certainty. The Earth's climate has never remained static for long and the prospect for human-accelerated climate change in the near future appears likely. Freshwater systems are intimately connected to climate in several ways: they may influence global atmospheric processes affecting climate; they may be sensitive early indicators of climate change because they integrate the atmospheric and terrestrial events occurring in their catchments; and, of course, they will be affected by climate change. An improved predictive understanding of environmental effects on pattern and process in freshwater ecosystems will be invaluable as a baseline upon which to build sound protection and management policies for fresh waters. This book represents an early step towards this improved understanding. The contributors accepted the challenge to assume global warming of 2-5oC in the next century. They then explored the implications of this scenario on various freshwater ecosystems and processes. To provide a broader perspective, Firth and Fisher included several chapters which do not deal expressly with freshwater ecosystems, but rather discuss climate change in terms of causes and mechanisms, implications for water resources, and the use of remote sensing as a tool for expanding studies from local to global scale.
