Forest Ecosystems, Forest Management and the Global Carbon Cycle


Book Description

Globally, forest vegetation and soils are both major stores of terrestrial organic carbon, and major contributors to the annual cycling of carbon between the atmosphere and the biosphere. Forests are also a renewable resource, vital to the everyday existence of millions of people, since they provide food, shelter, fuel, raw materials and many other benefits. The combined effects of an expanding global population and increasing consumption of resources, however, may be seriously endangering both the extent and future sustainability of the world's forests. About thirty chapters cover four main themes: the role of forests in the global carbon cycle; effects of past, present and future changes in forest land use; the role of forest management, products and biomass on carbon cycling, and socio-economic impacts.













Global Ecology


Book Description

Public awareness and concern over environmental degradation has reached an all time high, as the effect of man's activities on the global environment grows to greater and greater proportions. To understand the consequences of these activities, it is necessary to understand the fundamental nature of the system that supports life on a planetary scale. This book is the first interdisciplinary text on global ecology and is readable to students with only one to two years of science background. It contains a glossary of specialized terms which will enable students who are traditionally trained in geology, astronomy, and chemistry to understand the ecological topics presented. It places biogeochemical cycles witin a planetary perspective, and ties satellite technology, and applications to the earth sciences. As such, it can be the basis for new courses in planetary ecology, as well as being useful for present day ecology courses and seminars in environmental science.







Carbon Dioxide and Terrestrial Ecosystems


Book Description

The importance of carbon dioxide extends from cellular to global levels of organization and potential ecological deterioration may be the result of increased CO2 in our atmosphere. Recently, the research emphasis shifted from studies of photosynthesis pathways and plant growth to ground-breaking studies of carbon dioxide balances in ecosystems, regions, and even the entire globe. Carbon Dioxide and Terrestrial Ecosystems addresses these new areas of research. Economically important woody ecosystems are emphasized because they have substantial influence on global carbon dioxide balances. Herbaceous ecosystems (e.g., grasslands, prairies, wetlands) and crop ecosystems are also covered. The interactions among organisms, communities, and ecosystems are modeled, and the book closes with an important synthesis of this growing nexus of research. Carbon Dioxide and Terrestrial Ecosystems is a compilation of detailed scientific studies that reveal how ecosystems generally, and particular plants specifically, respond to changed levels of carbon dioxide. - Contributions from an international team of experts - Empirical examination of the actual effects of carbon dioxide - Variety of terrestrial habitats investigated - Specific plants and whole ecosystems offered as studies
