Book Synopsis The Carbon Balance of Forest Biomes by : Howard Griffith
Download or read book The Carbon Balance of Forest Biomes written by Howard Griffith and published by Garland Science. This book was released on 2004-08-15 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Carbon Balance of Forest Biomes provides an informed synthesis on the current status of forests and their future potential for carbon sequestration. This volume is timely, since convincing models which scale from local to regional carbon fluxes are needed to support these international agreements, whilst criticisms have been levelled at existing empirical approaches. One key question is to determine how well eddy-flux measurements at the stand-level represent regional-scale processes. This may be related to specific management practices (age, plantation, fertilisation) or simple bias in choosing representative sites (ease of access, roughness, proximity to physical barriers). The ecology and regeneration state of temperate, tropical and boreal forests under current climatic conditions are discussed, together with partitioning of photosynthetic and respiratory fluxes from soils and vegetation. The volume considers how to integrate contrasting methodologies, and the latest approaches for scaling from stand to the planetary boundary layer.
Book Synopsis Climate Change, Air Pollution and Global Challenges by : Kurt S. Pregitzer
Download or read book Climate Change, Air Pollution and Global Challenges written by Kurt S. Pregitzer and published by Elsevier Inc. Chapters. This book was released on 2013-11-19 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Aspen free-air carbon dioxide (CO2) enrichment (FACE) experiment tested how three developing forest communities responded to elevated concentrations of CO2 and/or tropospheric ozone (O3). Throughout the 11-year experiment, elevated CO2 increased aboveground productivity, whereas the initial negative effects of elevated O3 on aboveground productivity became insignificant over time. During the first 2 years, fine root biomass and soil respiration responded positively to elevated CO2 and negatively to elevated O3. However, after 5 years, O3 effects on fine root biomass were weakly negative or positive and effects on soil respiration were positive. Despite altering litter inputs, neither elevated O3 nor elevated CO2 affected overall soil C storage at the end of the experiment, consistent with observations that elevated CO2 increased and elevated O3 tended to decrease the activity of litter-degrading extracellular enzymes. Overall, our understanding of belowground processes is still insufficient to predict how ecosystems will respond to global change.

Book Synopsis The Microbial Regulation of Global Biogeochemical Cycles by : Johannes Rousk
Download or read book The Microbial Regulation of Global Biogeochemical Cycles written by Johannes Rousk and published by Frontiers E-books. This book was released on 2014-10-17 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global biogeochemical cycles of carbon and nutrients are increasingly affected by human activities. So far, modeling has been central for our understanding of how this will affect ecosystem functioning and the biogeochemical cycling of carbon and nutrients. These models have been forced to adopt a reductive approach built on the flow of carbon and nutrients between pools that are difficult or even impossible to verify with empirical evidence. Furthermore, while some of these models include the response in physiology, ecology and biogeography of primary producers to environmental change, the microbial part of the ecosystem is generally poorly represented or lacking altogether. The principal pool of carbon and nutrients in soil is the organic matter. The turnover of this reservoir is governed by microorganisms that act as catalytic converters of environmental conditions into biogeochemical cycling of carbon and nutrients. The dependency of this conversion activity on individual environmental conditions such as pH, moisture and temperature has been frequently studied. On the contrary, only rarely have the microorganisms involved in carrying out the processes been identified, and one of the biggest challenges for advancing our understanding of biogeochemical processes is to identify the microorganisms carrying out a specific set of metabolic processes and how they partition their carbon and nutrient use. We also need to identify the factors governing these activities and if they result in feedback mechanisms that alter the growth, activity and interaction between primary producers and microorganisms. By determining how different groups of microorganisms respond to individual environmental conditions by allocating carbon and nutrients to production of biomass, CO2 and other products, a mechanistic as well as quantitative understanding of formation and decomposition of organic matter, and the production and consumption of greenhouse gases, can be achieved. In this Research Topic, supported by the Swedish research councils' programme "Biodiversity and Ecosystem Services in a Changing Landscape" (BECC), we intend to promote this alternative framework to address how cycling of carbon and nutrients will be altered in a changing environment from the first-principle mechanisms that drive them – namely the ecology, physiology and biogeography of microorganisms – and on up to emerging global biogeochemical patterns. This novel and unconventional approach has the potential to generate fresh insights that can open up new horizons and stimulate rapid conceptual development in our basic understanding of the regulating factors for global biogeochemical cycles. The vision for the research topic is to facilitate such progress by bringing together leading scientists as proponents of several disciplines. By bridging Microbial Ecology and Biogeochemistry, connecting microbial activities at the micro-scale to carbon fluxes at the ecosystem-scale, and linking above- and belowground ecosystem functioning, we can leap forward from the current understanding of the global biogeochemical cycles.

Book Synopsis Disturbance Effects on Soil Carbon and Greenhouse Gas Emissions in Forest Ecosystems by : Scott X. Chang

This book was released on 2020-05-23 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest ecosystems are often disturbed by agents such as harvesting, fire, wind, insects and diseases, and acid deposition, with differing intensities and frequencies. Such disturbances can markedly affect the amount, form, and stability of soil organic carbon in, and the emission of greenhouse gases, including CO2, CH4, and N2O from, forest ecosystems. It is vitally important that we improve our understanding of the impact of different disturbance regimes on forest soil carbon dynamics and greenhouse gas emissions to guide our future research, forest management practices, and policy development. This Special Issue provides an important update on the disturbance effects on soil carbon and greenhouse gas emissions in forest ecosystems in different climate regions.

Book Synopsis Soil Respiration and the Environment by : Luo Yiqi
Download or read book Soil Respiration and the Environment written by Luo Yiqi and published by Elsevier. This book was released on 2010-07-20 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global environment is constantly changing and our planet is getting warmer at an unprecedented rate. The study of the carbon cycle, and soil respiration, is a very active area of research internationally because of its relationship to climate change. It is crucial for our understanding of ecosystem functions from plot levels to global scales. Although a great deal of literature on soil respiration has been accumulated in the past several years, the material has not yet been synthesized into one place until now. This book synthesizes the already published research findings and presents the fundamentals of this subject. Including information on global carbon cycling, climate changes, ecosystem productivity, crop production, and soil fertility, this book will be of interest to scientists, researchers, and students across many disciplines. A key reference for the scientific community on global climate change, ecosystem studies, and soil ecology Describes the myriad ways that soils respire and how this activity influences the environment Covers a breadth of topics ranging from methodology to comparative analyses of different ecosystem types The first existing "treatise" on the subject
Book Synopsis Effects of Drought on Forests and Rangelands in the United States by : James M. Vose
Download or read book Effects of Drought on Forests and Rangelands in the United States written by James M. Vose and published by . This book was released on 2016 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences for forest and rangeland values. Drought can be a severe natural disaster with substantial social and economic consequences. Drought becomes most obvious when large-scale changes are observed; however, even moderate drought can have long-lasting impacts on the structure and function of forests and rangelands without these obvious large-scale changes. Large, stand-level impacts of drought are already underway in the West, but all U.S. forests are vulnerable to drought. Drought-associated forest disturbances are expected to increase with climatic change. Management actions can either mitigate or exacerbate the effects of drought. A first principal for increasing resilience and adaptation is to avoid management actions that exacerbate the effects of current or future drought. Options to mitigate drought include altering structural or functional components of vegetation, minimizing drought-mediated disturbance such as wildfire or insect outbreaks, and managing for reliable flow of water.

Book Synopsis Effect of Three Afforestation Practices on Greenhouse Gas Fluxes by : Witness Mojeremane
Download or read book Effect of Three Afforestation Practices on Greenhouse Gas Fluxes written by Witness Mojeremane and published by LAP Lambert Academic Publishing. This book was released on 2014-02 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field experiment was established at Harwood Forest to investigate the effects of drainage, mounding and fertilisation on soil properties, environmental variables and carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) fluxes from an organic-rich peaty soil. The three greenhouse gases are actively changed between landscapes. Drainage significantly increased CO2, reduced CH4 fluxes but did not affect N2O fluxes. Mounding increased CH4 fluxes, reduced N2O but did not affect CO2. CO2, CH4 and N2O were increased by fertilisation. CO2 fluxes were mainly controlled by soil temperature, while CH4 was driven primarily by water table depth. N2O fluxes changed with changes in soil temperature and water table depth. Drainage and fertilisation were by far the most important afforestation practices tested in this in this work in terms of accelerating GHG fluxes from soil. Drainage increased overall CO2e fluxes, while the NPK fertilisation was the largest contributor to the total
