Résumé :
|
This book offers a comprehensive survey of the structure and functioning of forest ecosystems worldwide : temperate, tropical and boreal. Basic ecological concepts are stressed throughout, at scales ranging from the global to the microscopic. The text begins with an introduction to the basic elements of the science of ecology and the role of forests in the global ecosystem. The opening chapters describe how climate influences large-scale distribution of vegetation types, and how global warming might influence that distribution . After a look at factors that influence landscape patterns, the focus shifts to such topics as temporal dynamics, biological diversity, and soils. Subsequent chapters deal with primary productivity, nutrient cycling, herbivory, ecosysrtem stability, and factors contributing to ecosystem collapse, for example, acid rain and mismanagement. A concluding chapter discusses principles of sustainable forest management.
