Hodnocení: AnotaceThe Biology of Peatlands provides a comprehensive overview of peatland ecosystems. Coverage is international although there is a focus on boreal and north temperate peatlands. As a well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated.The book begins with an overview of the main peatland types (marsh, swamp, fen and bog), which provides the basis for a deeper understanding of the subject. Chapters then follow on the diversity of the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the moss genus Sphagnum, one of the most important functional plant groups in northern peatlands. Throughout the book, the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are stressed. In the study of peatland biology, it is essential to learn about peat itself and how its accumulation reflects the history and development of peatland over centrueies and millennia. The book therefore contains chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland successiona dn development. Several other key factors and precesses are then examined including hydrology, nutrient cycling, light, and temperature. The authors describe the intriguing patterns and landforms characteristic of peatlands in different parts of the world, together with theories on how they have developed. The role of peatlands as sources or sinks for atmospheric carbon dioxide and methane, and their influence on climatic change, is also outlined. A final chapter considers peatland management, conservation and restoration issues.This accessible text is suitable for students and researchers of peatlands as well as the professional ecologists and conservation biologists requiring a concise, authoritative and up-to-date overview of the topic.
