Download or read book Plant Litter written by Björn Berg and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the 2nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and with regard to current areas of investigation. The availability of several long-term studies allows a more in-depth approach to decomposition patterns and to the later stages of decomposition, as well as to humus formation and accumulation. The latest information focuses on three fields: - the effects of manganese on decomposition and possibly on carbon sequestration, - new findings on decomposition dynamics, and - the new analytical technique using 13C-NMR.

Download or read book Trees in a Changing Environment written by Michael Tausz and published by Springer. This book was released on 2014-08-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers current state-of-the-science knowledge of tree ecophysiology, with particular emphasis on adaptation to a novel future physical and chemical environment. Unlike the focus of most books on the topic, this considers air chemistry changes (O3, NOx, and N deposition) in addition to elevated CO2 effects and its secondary effects of elevated temperature. The authors have addressed two systems essential for plant life: water handling capacity from the perspective of water transport; the coupling of xylem and phloem water potential and flow; water and nutrition uptake via likely changes in mycorrhizal relationships; control of water loss via stomata and its retention via cellular regulation; and within plant carbon dynamics from the perspective of environmental limitations to growth, allocation to defences, and changes in partitioning to respiration. The authors offer expert knowledge and insight to develop likely outcomes within the context of many unknowns. We offer this comprehensive analysis of tree responses and their capacity to respond to environmental changes to provide a better insight in understanding likelihood for survival, as well as planning for the future with long-lived, stationary organisms adapted to the past: trees.

Download or read book Methods for Measuring Greenhouse Gas Balances and Evaluating Mitigation Options in Smallholder Agriculture written by Todd S. Rosenstock and published by Springer. This book was released on 2016-08-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides standards and guidelines for quantifying greenhouse gas emissions and removals in smallholder agricultural systems and comparing options for climate change mitigation based on emission reductions and livelihood trade-offs. Globally, agriculture is directly responsible for about 11% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries. Farms in the developing countries of sub-Saharan Africa and Asia are predominately managed by smallholders, with 80% of land holdings smaller than ten hectares. However, little to no information exists on greenhouse gas emissions and mitigation potentials in smallholder agriculture. Greenhouse gas measurements in agriculture are expensive, time consuming, and error prone, challenges only exacerbated by the heterogeneity of smallholder systems and landscapes. Concerns over methodological rigor, measurement costs, and the diversity of approaches, coupled with the demand for robust information suggest it is germane for the scientific community to establish standards of measurements for quantifying GHG emissions from smallholder agriculture. Standard guidelines for use by scientists, development organizations will help generate reliable data on emissions baselines and allow rigorous comparisons of mitigation options. The guidelines described in this book, developed by the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) and partners, are intended to inform anyone conducting field measurements of agricultural greenhouse gas sources and sinks, especially to develop IPCC Tier 2 emission factors or to compare mitigation options in smallholder systems.
Download or read book Greenhouse Gas Emissions Fluxes and Processes written by A. Tremblay and published by Springer Science & Business Media. This book was released on 2011-04-30 with total page 743 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a time when an unquestionable link between anthropogenic emissions of greenhouse gases and climatic changes has finally been acknowledged and * widely documented through IPCC reports, the need for precise estimates of greenhouse gas (GHG) production rates and emissions from natural as well as managed ecosystems has risen to a critical level. Future agreements between nations concerning the reduction of their GHG emissions will - pend upon precise estimates of the present level of these emissions in both natural and managed terrestrial and aquatic environments. From this viewpoint, the present volume should prove to a benchmark contribution because it provides very carefully assessed values for GHG emissions or exchanges between critical climatic zones in aquatic en- ronments and the atmosphere. It also provides unique information on the biases of different measurement methods that may account for some of the contradictory results that have been published recently in the literature on this subject. Not only has a large array of current measurement methods been tested concurrently here, but a few new approaches have also been developed, notably laser measurements of atmospheric CO concentration 2 gradients. Another highly useful feature of this book is the addition of - nitoring and process studies as well as modeling.
Download or read book The Paleoanthropology and Archaeology of Big Game Hunting written by John D. Speth and published by Springer Science & Business Media. This book was released on 2010-09-08 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its inception, paleoanthropology has been closely wedded to the idea that big-game hunting by our hominin ancestors arose, first and foremost, as a means for acquiring energy and vital nutrients. This assumption has rarely been questioned, and seems intuitively obvious—meat is a nutrient-rich food with the ideal array of amino acids, and big animals provide meat in large, convenient packages. Through new research, the author of this volume provides a strong argument that the primary goals of big-game hunting were actually social and political—increasing hunter’s prestige and standing—and that the nutritional component was just an added bonus. Through a comprehensive, interdisciplinary research approach, the author examines the historical and current perceptions of protein as an important nutrient source, the biological impact of a high-protein diet and the evidence of this in the archaeological record, and provides a compelling reexamination of this long-held conclusion. This volume will be of interest to researchers in Archaeology, Evolutionary Biology, and Paleoanthropology, particularly those studying diet and nutrition.
Download or read book Object Based Image Analysis written by Thomas Blaschke and published by Springer Science & Business Media. This book was released on 2008-08-09 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a collection of invited interdisciplinary persp- tives on the recent topic of Object-based Image Analysis (OBIA). Its c- st tent is based on select papers from the 1 OBIA International Conference held in Salzburg in July 2006, and is enriched by several invited chapters. All submissions have passed through a blind peer-review process resulting in what we believe is a timely volume of the highest scientific, theoretical and technical standards. The concept of OBIA first gained widespread interest within the GIScience (Geographic Information Science) community circa 2000, with the advent of the first commercial software for what was then termed ‘obje- oriented image analysis’. However, it is widely agreed that OBIA builds on older segmentation, edge-detection and classification concepts that have been used in remote sensing image analysis for several decades. Nevert- less, its emergence has provided a new critical bridge to spatial concepts applied in multiscale landscape analysis, Geographic Information Systems (GIS) and the synergy between image-objects and their radiometric char- teristics and analyses in Earth Observation data (EO).

Download or read book Lithic Technological Organization and Paleoenvironmental Change written by Erick Robinson and published by Springer. This book was released on 2017-11-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this edited volume is to bring together a diverse set of analyses to document how small-scale societies responded to paleoenvironmental change based on the evidence of their lithic technologies. The contributions bring together an international forum for interpreting changes in technological organization - embracing a wide range of time periods, geographic regions and methodological approaches. As technology brings more refined information on ancient climates, the research on spatial and temporal variability of paleoenvironmental changes. In turn, this has also broadened considerations of the many ways that prehistoric hunter-gatherers may have responded to fluctuations in resource bases. From an archaeological perspective, stone tools and their associated debitage provide clues to understanding these past choices and decisions, and help to further the investigation into how variable human responses may have been. Despite significant advances in the theory and methodology of lithic technological analysis, there have been few attempts to link these developments to paleoenvironmental research on a global scale.
Download or read book The Global Climate written by John T. Houghton and published by CUP Archive. This book was released on 1985-09-05 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in paperback, this book has succeeded in its aim to introduce the global climate problem and the complex processes and interactions which play a part in climatic change to a wide range of scientists working in climatic research or the related fields of meteorology, oceanography, glaciology and hydrology. It is centred around the World Climate Research Programme, an international enterprise jointly sponsored by the scientific community (through the International Council of Scientific Unions) and the national weather centres (through the World Meteorological Organisation). If progress is to be made in understanding climatic change, it is necessary to observe and understand all components of the climate system and the interactions between them. This book is particularly relevant to many contemporary climatic problems and to the two most important questions arising tom them: to what extent can changes in climate be predicted; and what is the extent of man's influence on climate. The Global Climate answers these questions, showing how the important processes may be -observed, evaluated and modelled by computer.
Download or read book From Kostenki to Clovis written by Olga Soffer and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the American Side I went to the USSR for the first time in 1982 to attend the 11th meeting of the International Union for Quaternary research (INQUA) held at the Moscow State University. At that time relations between our two countries were anything but congenial and many restrictions were placed on our viewing the archaeological and paleontological collections and labora tory facilities. This was not the ideal climate for the free exchange of ideas needed for meaningful research. However, it was obvious to us that the strained relations did not extend to scientific discussions between scholars. We left that meeting well aware that if the problems of prehistoric Old World-New World relationships were to be resolved, it would eventually require cooperative research efforts within the world community of archaeologists. At that time, the pre-Clovis problem in New World archaeology was foremost in the minds of many North American researchers: tool technology and assemblages were being studied as a possible means of establishing cultural relationships across the Bering Strait, Clovis sites and mammoth kills were being looked at with new ideas for interpretation, and New World researchers realized that to resolve these questions they had to become familiar with the archaeological record of northeast Asia. A chance meeting of the writer with Olga Soffer in 1983 led to serious discussions of the sites on the Russian or East European Plain.
