The Ecology of Browsing and Grazing
Extensive grazing and browsing by domestic and wild herbivores shape the vegetation composition, structure and dynamics of many terrestrial ecosystems. This volume investigates how large herbivores not only influence the structure and distribution of the vegetation, but also affect nutrient flows and the responses of associated fauna. The mechanisms and processes underlying the herbivores' behaviour, distribution, movement and direct impact on the vegetation, and the dynamics of nutrients, plant species, and vegetation composition in terrestrial ecosystems are discussed in detail. It is shown that an understanding of plant/animal interactions can provide practical advice on the management of large herbivores to integrate production and conservation in terrestrial systems, particularly in the face of environmental and climate change.
Plant Litter : Decomposition, Humus Formation, Carbon Sequestration
This fully revised and updated 2nd edition of Plant Litter focuses on decomposition processes in natural terrestrial systems such as boreal and temperate forests. The availability of several long-term studies from these forest types allows a more in-depth approach to the later stages of decomposition as well as to humus formation. It further briefly explores how processes are modified due to anthropogenic influences. Earlier findings are re-evaluated in light of recent research and with relevance to current areas of investigation. New concepts that modify or go beyond those already presented are covered and a new chapter on patterns of decomposition and accumulation on a regional scale was introduced.
Ecological Risk Assessment for Chlorpyrifos in Terrestrial and Aquatic Systems in the United States
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.
Chemical Ecology : From Gene to Ecosystem
This book provides an overview of chemical ecology related to different ecosystems. It offers an outlook at novel directions that can be taken in chemical ecology through a molecular-ecological or eco-genomic approach. The book addresses aboveground and belowground terrestrial systems as well as aquatic systems, and the organisms involved are micro- and macro-organisms, such as plants, arthropods and mammals.
Boreal Forest and Climate Change
There are several crucial feedbacks from forests to the climate system. The mechanisms for those feedbacks are elaborated in the book: they involve changes in the carbon cycle, albedo, N2O emissions and the production of aerosols. Much of this work is new and the feedback relationships have not yet been incorporated into models of the climate system. The book will be an important introduction for students and climate modellers alike, providing conceptual tools and ideas that are broadly applicable to terrestrial systems.
