Environmental Standards
The rapid growth of the world population - nearly six-fold over the last hundred years - combined with the rising number of technical installations especially in the industrialized countries has lead to ever tighter and more strained living spaces on our planet. Because ofthe inevitable processes oflife, man was at first an exploiter rather than a careful preserver of the environment. Environmental awareness with the intention to conserve the environment has grown only in the last few decades. Environmental standards have been defined and limit values have been set largely guided, however, by scientific and medical data on single exposures, while public opinion, on the other hand, now increasingly calls for astronger consideration of the more complex situations following combined exposures. Furthermore, it turned out that environmental standards, while necessarily based on scientific data, must also take into account ethical, legal, economic, and sociological aspects. A task of such complexity can only be dealt with appropriately in the framework of an inter disciplinary group.

Publisher Description
Biogeochemistry of Forested Catchments in a Changing Environment
Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in ...
Microbial Ecology of Aerial Plant Surfaces
All aerial plant surfaces, including leaves, stems and flowers are inhabited by diverse assemblages of microorganisms, including filamentous fungi, yeasts, bacteria, and bacteriophages. These organisms have profound effects on plant health and thus impact on ecosystem and agricultural functions. This book is based on proceedings from the 8th International Symposium on the mircobiology of aerial plant surfaces, held in Oxford 2005. This is a five yearly conference which brings together international scientists and provides a unique opportunity to discuss developments in this field.
Insects and Ecosystem Function
Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume examines their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work.
Flux Control in Biological Systems
Comprehending and modelling biomass production, nutrient, and water fluxes in biological systems requires understanding control mechanisms at various levels of organiztion. This new book, with 16 pages of four-colorplates, compares patterns and mechanisms of regulation-starting from enzyme reactions and ending at the population and ecosystem level. By doing so, the book investigates the general principles of how fluxes are adjusted and regulated. Such principles areessential for preparing effective models and for predicting human impacts on ecosystems. Flux Control in Biological Systems: From Enzymes to Populations and Ecosystems will be an essential personal library addition for student and professional environmental biologists, ecologists, physiologists, biochemists, botanists, microbiologists, soil scientists, and zoologists; as well as anyone who investigate patterns of matter and energy transfer in biological systems of different levels of complexity.* Presents the mechanisms of flux control* Explains the similarities of flux control at various levels of complexity and organization* Demonstrates how fluxes are adjusted in complex systems of interacting groups of organisms

Hemlock
The Eastern Hemlock, massive and majestic, has played a unique role in structuring northeastern forest environments, from Nova Scotia to Wisconsin and through the Appalachian Mountains to North Carolina, Tennessee, and Alabama. A “foundation species” influencing all the species in the ecosystem surrounding it, this iconic North American tree has long inspired poets and artists as well as naturalists and scientists. Five thousand years ago, the hemlock collapsed as a result of abrupt global climate change. Now this iconic tree faces extinction once again because of an invasive insect, the hemlock woolly adelgid. Drawing from a century of studies at Harvard University’s Harvard Forest, one of the most well-regarded long-term ecological research programs in North America, the authors explore what hemlock’s modern decline can tell us about the challenges facing nature and society in an era of habitat changes and fragmentation, as well as global change.
