This is the first truly ecosystem-oriented book on peatlands. It adopts an ecosystems approach to understanding the world's boreal peatlands. The focus is on biogeochemical patterns and processes, production, decomposition, and peat accumulation, and it provides additional information on animal and fungal diversity. A recurring theme is the legacy of boreal peatlands as impressive accumulators of carbon as peat over millennia.
This book is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon–water flux/storage, biodiversity and peatland management in tropical regions. It is estimated that more than 23 million hectares (62 %) of the total global tropical peatland area are located in Southeast Asia, in lowland or coastal areas of East Sumatra, Kalimantan, West Papua, Papua New Guinea, Brunei, Peninsular Malaysia, Sabah, Sarawak and Southeast Thailand. Tropical peatland has a vital carbon–water storage function and is host to a huge diversity of plant and animal species. Peatland ecosystems are extremely vulnerable to climate change and the impacts of human activities such as logging, drainage and conversion to agricultural land. In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation. Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland loss. Thus, tropical peatlands are key ecosystems in terms of the carbon–water cycle and climate change.
Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining 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 genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.
Global Climate Change and Cold Regions Ecosystems provides information on soil processes and the carbon cycle in cold ecoregions as well as the soil carbon pool and its fluxes in the soils of cold ecoregions. Filling a void in this area of soil science, this resource explains soil processes influencing C dynamics under natural and disturbed ecosystems. The soils of the cold region ecosystems serve as a net sink of atmospheric C. However, an increase in global temperature could render them a net source. In the event of global warming, the cold regions ecosystems-arctic, sub-arctic, alpine, Antarctic, boreal forests, and peatlands-will undergo radical changes. Potential environmental change could drastically increase the active soil layer and influence the large C pool found in them. Topics include: soil C pools in different cold ecoregions, the impact of natural and anthropogenic disturbances on the soil C pool, the method of assessment of C and other properties of soils of the cold regions ecosytems while focusing on the fate of C in permafrost soils. Global Climate Change and Cold Regions Ecosystems covers the current and possible future effects of the cold ecoregions soil C pool on the global carbon pool.
