Book Description
This publication provides extended abstracts of papers presented at a workshop on forested peatland carbon dynamics. Topics of papers include peat accumulation, carbon flux measurements, peatlands of the western boreal forest and the Mackenzie Valley, the carbon chemistry of peat, the effect of temperature on microbial decomposition, modelling carbon accumulation, peatland hydrology modelling, peatland fire & impacts on carbon dynamics, soil carbon dynamics in the boreal forest, and how peat fits into the Kyoto Protocol.

Book Description
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.

Book Description
In the past two decades there has been considerable work on global climatic change and its effect on the ecosphere, as well as on local and global environmental changes triggered by human activities. From the tropics to the Arctic, peatlands have developed under various geological conditions, and they provide good records of global and local changes since the Late Pleistocene.The objectives of the book are to analyze topics such as geological evolution of major peatlands basins; peatlands as self sustaining ecosystems; chemical environment of peatlands: water and peat chemistry; peatlands as archives of environmental changes; influence of peatlands on atmosphere: circular complex interactions; remote sensing studies of peatlands; peatlands as a resource; peatlands degradation, restoration, plus more.* Presents an interdisciplinary approach, with an emphasis on Earth Science, and addresses the need for intergration between subdisciplines and the developing of new approaches* Synthesizes the evolutionary, ecological, and chemical characteristics of major peatlands, as well as focuses on the environmental changes, from climate changes to surface ares changes due to human activities* Covers topical studies of worldwide interest and provides examples from many different countries

Book Description
In peatlands, both internal dynamics and external forcing drive changes in hydrological conditions and vegetation communities, which affect short- and long-term peat accumulation processes and associated carbon sequestration. Understanding the spatial and temporal dynamics of these autogenic and allogenic controls is of critical importance for documenting peatland development and assessing the peatland carbon-sink function, especially because climatically-induced changes in peatland hydrology and vegetation are likely to have considerable effects on peat-carbon fluxes. In my dissertation, I present a range of evidence from Alaska and Patagonia demonstrating that peatland-carbon dynamics are controlled by hierarchical interactions between regional climate dynamics, landscape morphology, and spatially-explicit local community structures.

Book Description
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.

Book Description
In March, 2004, Water Survey of Canada and the Canadian Society for Hydrological Sciences co-hosted a workshop in Yellowknife to discuss how to improve our community's abilities to predict streamflow in the Mackenzie Valley and similar cold regions of Canada. The workshop's objectives were to: 1) provide outreach to practitioners of the results of recent studies in cold water regions hydrological regimes in the context of predicting streamflow; 2) assess "state of the art" techniques to predict streamflow in ungauged basins in northern landscapes, and; 3) define technical needs and recommend a research agenda that can deliver these over the next decade. This book summarizes presentations by invited speakers on the subjects of: statisical hydrology and hydrometric network planning; cold regions hydrological processes; application of hydrological models to cold regions; and advances in distributed hydrological modelling.
