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.
Book Synopsis Carbon Dioxide and Environmental Stress by : Luo Yiqi
Download or read book Carbon Dioxide and Environmental Stress written by Luo Yiqi and published by Elsevier. This book was released on 1999-04-13 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the interactive effects of environmental stresses with plant and ecosystem functions, especially with respect to changes in the abundance of carbon dioxide. The interaction of stresses with elevated carbon dioxide are presented from the cellular through whole plant ecosystem level. The book carefully considers not only the responses of the above-ground portion of the plant, but also emphasizes the critical role of below-ground (rhizosphere) components (e.g., roots, microbes, soil) in determining the nature and magnitude of these interactions. * Will rising CO2 alter the importance of environmental stress in natural and agricultural ecosystems?* Will environmental stress on plants reduce their capacity to remove CO2 from the atmosphere?* Are some stresses more important than others as we concern ourselves with global change?* Can we develop predictive models useful for scientists and policy-makers?* Where should future research efforts be focused?
Book Synopsis Belowground Responses to Rising Atmospheric CO2: Implications for Plants, Soil Biota, and Ecosystem Processes by : P. S. Curtis
Download or read book Belowground Responses to Rising Atmospheric CO2: Implications for Plants, Soil Biota, and Ecosystem Processes written by P. S. Curtis and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: As atmospheric CO2 increases there will almost certainly be alterations in soil carbon fluxes. It is likely that such alterations will be accompanied by changes in the partitioning of carbon between organic structures and to soil processes. These changes have the potential for further altering the structure and function of terrestrial ecosystems. While there has been increasing recognition of the importance of soil-mediated responses to global climate change, the nature and magnitude of these responses are not well understood. In an effort to expand our assessment of the significance of belowground responses to rising atmospheric CO2, a workshop has been organized that resulted in the peer-reviewed contributions that are contained in this volume.
Book Synopsis Carbon Dioxide and Terrestrial Ecosystems by : George W. Koch
Download or read book Carbon Dioxide and Terrestrial Ecosystems written by George W. Koch and published by Elsevier. This book was released on 1995-12-21 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of carbon dioxide extends from cellular to global levels of organization and potential ecological deterioration may be the result of increased CO2 in our atmosphere. Recently, the research emphasis shifted from studies of photosynthesis pathways and plant growth to ground-breaking studies of carbon dioxide balances in ecosystems, regions, and even the entire globe. Carbon Dioxide and Terrestrial Ecosystems addresses these new areas of research. Economically important woody ecosystems are emphasized because they have substantial influence on global carbon dioxide balances. Herbaceous ecosystems (e.g., grasslands, prairies, wetlands) and crop ecosystems are also covered. The interactions among organisms, communities, and ecosystems are modeled, and the book closes with an important synthesis of this growing nexus of research. Carbon Dioxide and Terrestrial Ecosystems is a compilation of detailed scientific studies that reveal how ecosystems generally, and particular plants specifically, respond to changed levels of carbon dioxide. Contributions from an international team of experts Empirical examination of the actual effects of carbon dioxide Variety of terrestrial habitats investigated Specific plants and whole ecosystems offered as studies

Book Synopsis The Carbon Cycle by : T. M. L. Wigley
Download or read book The Carbon Cycle written by T. M. L. Wigley and published by Cambridge University Press. This book was released on 2005-08-22 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing carbon dioxide (CO2) emissions is imperative to stabilizing our future climate. Our ability to reduce these emissions combined with an understanding of how much fossil-fuel-derived CO2 the oceans and plants can absorb is central to mitigating climate change. In The Carbon Cycle, leading scientists examine how atmospheric carbon dioxide concentrations have changed in the past and how this may affect the concentrations in the future. They look at the carbon budget and the "missing sink" for carbon dioxide. They offer approaches to modeling the carbon cycle, providing mathematical tools for predicting future levels of carbon dioxide. This comprehensive text incorporates findings from the recent IPCC reports. New insights, and a convergence of ideas and views across several disciplines make this book an important contribution to the global change literature.

Book Synopsis The Phanerozoic Carbon Cycle by : Robert A. Berner
Download or read book The Phanerozoic Carbon Cycle written by Robert A. Berner and published by Oxford University Press. This book was released on 2004-08-19 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "carbon cycle" is normally thought to mean those processes that govern the present-day transfer of carbon between life, the atmosphere, and the oceans. This book describes another carbon cycle, one which operates over millions of years and involves the transfer of carbon between rocks and the combination of life, the atmosphere, and the oceans. The weathering of silicate and carbonate rocks and ancient sedimentary organic matter (including recent, large-scale human-induced burning of fossil fuels), the burial of organic matter and carbonate minerals in sediments, and volcanic degassing of carbon dioxide contribute to this cycle. In The Phanerozoic Carbon Cycle, Robert Berner shows how carbon cycle models can be used to calculate levels of atmospheric CO[2 and O[2 over Phanerozoic time, the past 550 million years, and how results compare with independent methods. His analysis has implications for such disparate subjects as the evolution of land plants, the presence of giant ancient insects, the role of tectonics in paleoclimate, and the current debate over global warming and greenhouse gases

Book Synopsis Aboveground-Belowground Linkages by : Richard D. Bardgett
Download or read book Aboveground-Belowground Linkages written by Richard D. Bardgett and published by Oxford University Press. This book was released on 2010-07-29 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aboveground-Belowground Linkages provides the most up-to-date and comprehensive synthesis of recent advances in our understanding of the roles that interactions between aboveground and belowground communities play in regulating the structure and function of terrestrial ecosystems, and their responses to global change. It charts the historical development of this field of ecology and evaluates what can be learned from the recent proliferation of studies on the ecological and biogeochemical significance of aboveground-belowground linkages. The book is structured around four key topics: biotic interactions in the soil; plant community effects; the role of aboveground consumers; and the influence of species gains and losses. A concluding chapter draws together this information and identifies a number of cross-cutting themes, including consideration of aboveground-belowground feedbacks that occur at different spatial and temporal scales, the consequences of these feedbacks for ecosystem processes, and how aboveground-belowground interactions link to human-induced global change.

Book Synopsis Effects of Elevated Atmospheric CO2 on Soil Organic Carbon Dynamics in a Mediterranean Forest Ecosystem by : Fayez Raiesi Gahrooee
Download or read book Effects of Elevated Atmospheric CO2 on Soil Organic Carbon Dynamics in a Mediterranean Forest Ecosystem written by Fayez Raiesi Gahrooee and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elevated atmospheric CO2 has the potential to change the composition and dynamics of soil organic matter (SOM) and consequently C and N cycling in terrestrial ecosystems. Because of the long-lived nature of SOM, long-lasting experiments are required for studying the effect of elevated CO2 on soil organic matter dynamics. Therefore, the study of ecosystems that have been exposed to long-term enhanced CO2 concentrations is highly desirable for better understanding feedback mechanisms between litter production, litter quality, soil organic matter decomposability and the atmospheric CO2 level. This work deals with the effect of enhanced atmospheric CO2 on chemical composition and C and N mineralization in a leaf litter-soil organic matter continuum around a mineral CO2 spring in a Mediterranean woodland ecosystem. Leaf litter from Quercus cerris L., Quercus pubescens Willd. and Smilax aspera L., and soil samples from the forest floor (F and HA layers) and 0-10 cm mineral soil were taken at elevated and ambient CO2 concentrations, and analyzed for chemical composition (C, N, lignin, cellulose, polyphenols). C and N mineralization in plant litter and soil samples were determined using litterbag and laboratory incubation methods. Elevated CO2 affected neither chemical composition nor elemental ratios of leaf litter. The C mineralization rate during litter decomposition was not affected by elevated CO2, in accordance with the absence of a CO2 effect on litter quality. Leaf litter produced at high CO2 had a higher N mineralization during the initial stage of decomposition period. This difference, however, disappeared at the end of the incubation. Q. pubescens had a higher litter quality than Q. cerris, and subsequently in vitro faster C and N mineralization rates, but litter decomposition under field conditions did not differ significantly between the two species. Total C contents in the forest floor were higher at elevated CO2, but not so in the 0-10 cm mineral soil. For the three layers, total N contents and C/N ratios were not affected by elevated CO2. Total C and N pool sizes in the forest floor were doubled by elevated CO2, but such effects were not seen in the 0-10 cm mineral soil. The C mineralization rates of the three soil layers of the areas exposed to elevated CO2 did not differ from those of the areas under ambient conditions. Although N immobilization in the F and HA layers from the elevated CO2 plots was lower, that of the 0-10 cm A horizon was not affected by high CO2. The increase in the organic carbon pool of the forest floor in the absence of an effect of elevated CO2 on litter quality and decomposability can be explained by increased biomass production under elevated CO2. Under elevated CO2 soil N pools also increased, but the rate of N immobilization in forest floor was lower than that under ambient CO2. This study of long-term CO2 effects casts some doubt on the common view that elevated CO2 changes litter quality of plants, and thereby slows down decomposability of litter and N release. Because species composition has a strong influence on C and N cycles than elevated CO2, effects of increasing atmospheric CO2 on species composition may be more important to feedbacks between CO2 concentration and soil organic matter than the CO2 effect on litter quality of a given species.
