Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 184. Carbon Cycling in Northern Peatlands examines the role that northern peatlands play in regulating the atmospheric carbon budget. It summarizes current research in four interconnected areas: large-scale peatland dynamics and carbon cycling; plant and microbial dynamics and their effect on carbon fluxes to the atmosphere; methane accumulation in, and loss from, peatlands; and water and dissolved carbon fluxes through peatlands. The volume highlights include A thorough assessment of the challenges involved in incorporating carbon cycling in northern peatlands into global climate models; A conceptual model to examine the partitioning of terminal carbon mineralization into production of CO2 and CH4; A comprehensive review of the evidence for the accumulation of methane in deep and shallow peat; and A description of the hydrologic changes induced by peat harvesting and associated challenges in restoring altered peatlands to their natural hydrologic regime. Carbon Cycling in Northern Peatlands will be of interest to research scientists and graduate and undergraduate students, particularly those who wish to know more about the role of peatlands in the global carbon cycle and their role as modifiers of climate.

Available in PDF, EPUB and Kindle. Book excerpt: New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cross-disciplinary overview of permafrost and the carbon cycle by providing an introduction into the geographical distribution of permafrost, with a focus on the distribution of permafrost and its soil carbon reservoirs. The chapters explain the basic physical properties and processes of permafrost soils: ice, mineral and organic components, and how these interact with climate, vegetation and geomorphological processes. In particular, the book covers the role of the large quantities of ice in many permafrost soils which are crucial to understanding carbon cycle processes. An explanation is given on how permafrost becomes loaded with ice and carbon. Gas hydrates are also introduced. Structures and processes formed by the intense freeze-thaw action in the active layer are considered (e.g. ice wedging, cryoturbation), and the processes that occur as the permafrost thaws, (pond and lake formation, erosion). The book introduces soil carbon accumulation and decomposition mechanisms and how these are modified in a permafrost environment. A separate chapter deals with deep permafrost carbon, gas reservoirs and recently discovered methane emission phenomena from regions such as Northwest Siberia and the Siberian yedoma permafrost.

This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulations of increased CO2 also confirmed positive growth response in the short term. The response of soil carbon was similar, however predicted to be less than the increase of biomass. Nitrogen availability and negative feedback mechanisms of the plant soil system were critical to the results, indicating that nitrogen progressively limited the growth response.

Download or read book Tropical Peatlands written by Jack Rieley and published by Earthscan / James & James. This book was released on 2012-01-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical peatlands are found mostly in South East Asia, but also in Africa and in Central and South America. They and peat-swamp forests store large amounts of carbon and their destruction, particularly through the development of plantations for oil palm and other forms of agriculture, releases large quantities of greenhouse gases which contribute to climate change. They are also complex and vulnerable ecosystems, home to great biodiversity and a number of endangered species such as the orang utan.The aim of this book is to introduce this little known but important and vulnerable ecosystem in a way that explains its long standing interaction with the global carbon cycle and how it is being destroyed by deforestation and inappropriate development. The authors describe the origin and formation of peat in the tropics, its current location, extent and amount of carbon stored in it, its biodiversity and natural resource functions and key ecological functions and processes. Appropriate hydrology is the key to the development and maintenance of peatlands and the unique aspects of tropical peatland water supply and management are also explored. In the same vein the nutrient dynamics and budgets of this ecosystem are explained in order to show how complex habitats can be maintained mainly by rainwater containing very low concentrations of essential chemical elements. Past and present impacts on tropical peatlands in SE Asia are discussed and the need for restoration and wise use highlighted. Finally, projections are made about the future of this ecosystem as a result of continuing human impacts and climate change.

Available in PDF, EPUB and Kindle. Book excerpt: A must-have introduction to this fundamental driver of the climate system The Global Carbon Cycle is a short introduction to this essential geochemical driver of the Earth's climate system, written by one of the world's leading climate-science experts. In this one-of-a-kind primer, David Archer engages readers in clear and simple terms about the many ways the global carbon cycle is woven into our climate system. He begins with a concise overview of the subject, and then looks at the carbon cycle on three different time scales, describing how the cycle interacts with climate in very distinct ways in each. On million-year time scales, feedbacks in the carbon cycle stabilize Earth's climate and oxygen concentrations. Archer explains how on hundred-thousand-year glacial/interglacial time scales, the carbon cycle in the ocean amplifies climate change, and how, on the human time scale of decades, the carbon cycle has been dampening climate change by absorbing fossil-fuel carbon dioxide into the oceans and land biosphere. A central question of the book is whether the carbon cycle could once again act to amplify climate change in centuries to come, for example through melting permafrost peatlands and methane hydrates. The Global Carbon Cycle features a glossary of terms, suggestions for further reading, and explanations of equations, as well as a forward-looking discussion of open questions about the global carbon cycle.

Download or read book Carbon Cycling at a Post-extraction Restored Peatland written by Kelly Nugent and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Peatlands store large amounts of organic carbon (C) and are an important component of the global climate system. Climate and peatland land surfaces are closely coupled through land-atmosphere exchanges of greenhouse gases (GHG), such as carbon dioxide (CO2) and methane (CH4). When undisturbed, peatlands exert a long-term (millennia) negative radiative GHG forcing (climate cooling) through CO2 removal from the atmosphere, and a short-term (decades) positive forcing (climate warming) with the addition of CH4 to the atmosphere. Peatland drainage and extraction, however, results in mineralization of stored peat, releasing large amounts of CO2 while generally reducing CH4 to minimal levels. Rewetting and actively restoring vegetation is now a restoration approach used to reduce CO2 emissions from degraded peatlands. However, the timeframe needed for restoration to re-establish the C sink function of an undisturbed peatland remains poorly constrained due to a lack of multi-year measurements. In this thesis, I analyze three years of eddy covariance flux measurements from a post-extraction restored peatland in eastern Quebec, Canada that was restored 14 years prior. I link these measurements with flux footprint modelling, stable isotope fractionation data and pore water concentrations to characterize how belowground C cycling and fluxes are impacted by restoration. I combine a series of flux towers at post-extraction unrestored and restored peatlands in eastern and western Canada with an atmospheric perturbation model to further reveal how after-use management is affecting the global climate.The post-extraction restored peatland was a C sink of 78 ± 17 g C m-2 yr-1 within fourteen years of restoration, due to strong CO2 uptake and small CH4 emission and dissolved organic carbon export. A comparison with an undisturbed reference peatland (Mer Bleue) revealed annual NEE at the restored peatland was most similar to wetter, more productive years at the reference peatland. A mapping of post-extraction (1980 onwards) canopy structure changes showed broad comparability between the restored peatland and surrounding intact peatland within five years of restoration. The enhanced vegetation index results suggest that the developing vegetation in general had a normal response to environmental factors and was not experiencing any enduring stress from the underlying cutover peat. While the processes behind the surface net CO2 flux appear successfully recovered, approximately two thirds of the restored peatland was a minimal source of CH4, suggesting a lag in the recovery of belowground C cycling processes. Carbon turnover in the cutover peat beneath the new Sphagnum layer was slow and appeared to occur only with E. vaginatum substrate input and plant-mediated transport. The C isotopic fractionation factor for CH4 and CO2 in the restored field pore water exhibited a dominance of acetoclastic methane production, even deeper in the cutover peat profile. In contrast, isotopic fractionation in the former drainage ditches showed a balance of acetoclastic and hydrogenotrophic methanogenesis deeper in the profile, indicating that some bulk peat C turnover was occurring. Over time (decades), C turnover of the new peat is expected to limit the impacts of the cutover peat on the surface CH4 flux.Flux measurements at unrestored sites in eastern and western Canada reveal that not restoring post-extraction peatlands leads to decades of CO2 addition to the atmosphere, with low CH4 emission. The after-use decision to not restore results in a positive radiative forcing seven times more powerful than the negative forcing achieved by active restoration after 500 years. Prompt active restoration achieves a neutral climate impact about 155 years earlier than restoration after a 20-year delay. In contrast, IPCC Tier 1 emission factors based on a wide range of rewetting activities display a continually positive radiative forcing, even with prompt rewetting"--

This book was released on 2013-06-29 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, forest vegetation and soils are both major stores of terrestrial organic carbon, and major contributors to the annual cycling of carbon between the atmosphere and the biosphere. Forests are also a renewable resource, vital to the everyday existence of millions of people, since they provide food, shelter, fuel, raw materials and many other benefits. The combined effects of an expanding global population and increasing consumption of resources, however, may be seriously endangering both the extent and future sustainability of the world's forests. About thirty chapters cover four main themes: the role of forests in the global carbon cycle; effects of past, present and future changes in forest land use; the role of forest management, products and biomass on carbon cycling, and socio-economic impacts.

This book was released on 2004 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the literature on carbon cycling in northern wetlands, with a focus on peatlands in the context of carbon assessment in boreal peatlands of Ontario. The report first introduces the topic of peatland carbon cycling and the importance of vegetation & hydrologic interactions in its regulation. It also presents components of peatland carbon budgets. The next section lists the uncertainties in global estimates of wetland extent and describes the boreal wetland regions & wetland types in Canada, including peatlands in Ontario. Section three covers the following: peatland net primary production & litter decomposition; peat accumulation & carbon sequestration; carbon storage in Ontario boreal peatlands; carbon cycling dynamics; methane production & emission; the importance of peatlands to atmospheric carbon dioxide concentrations; measures of carbon dioxide exchange in peatlands; and the relation between climate change and peatland carbon cycling. Section four discusses various approaches used to scale peatland carbon to landscape, regional, & global levels, focussing on carbon dioxide & methane. The final section reviews the Ontario peatland resource and summarizes the knowledge gaps that remain before accurate assessments of peatland carbon budgets are possible.
