Book Description
Changes in atmospheric carbon dioxide concentrations and global climate conditions have altered photosynthesis and plant respiration across both geologic and contemporary time scales. Understanding climate change effects on plant carbon dynamics is critical for predicting plant responses to future growing conditions. Furthermore, demand for biofuel, fibre and food production is rapidly increasing with the ever-expanding global human population, and our ability to meet these demands is exacerbated by climate change. This volume integrates physiological, ecological, and evolutionary perspectives on photosynthesis and respiration responses to climate change. We explore this topic in the context of modeling plant responses to climate, including physiological mechanisms that constrain carbon assimilation and the potential for plants to acclimate to rising carbon dioxide concentration, warming temperatures and drought. Additional chapters contrast climate change responses in natural and agricultural ecosystems, where differences in climate sensitivity between different photosynthetic pathways can influence community and ecosystem processes. Evolutionary studies over past and current time scales provide further insight into evolutionary changes in photosynthetic traits, the emergence of novel plant strategies, and the potential for rapid evolutionary responses to future climate conditions. Finally, we discuss novel approaches to engineering photosynthesis and photorespiration to improve plant productivity for the future. The overall goals for this volume are to highlight recent advances in photosynthesis and respiration research, and to identify key challenges to understanding and scaling plant physiological responses to climate change. The integrated perspectives and broad scope of research make this volume an excellent resource for both students and researchers in many areas of plant science, including plant physiology, ecology, evolution, climate change, and biotechnology. For this volume, 37 experts contributed chapters that span modeling, empirical, and applied research on photosynthesis and respiration responses to climate change. Authors represent the following seven countries: Australia (6); Canada (9), England (5), Germany (2), Spain (3), and the United States (12).

Book Description
This comprehensive book discusses the ecophysiological features of trees affected by the two most prominent factors of climate change: atmospheric CO2 concentration and temperature. It starts with the introduction of experimental methods at the leaf, branch, the whole-tree, and tree group scales, and in the following chapters elaborates on specific topics including photosynthesis of leaves, respiration of plant organs, water use efficiency, the production of and/or distribution patterns of carbohydrates, secondary metabolites, and nutrients, anatomy of cells and tissues, height and stem-diameter growth, biomass accumulation, leaf phenology and longevity, and model ecosystems (soil-litter-plant enclosures). The current knowledge is neatly summarized, and the author presents valuable data derived from his 30 years of experimental research, some of which is published here for the first time. Using numerous examples the book answers the fundamental questions such as: What are the interactions of elevated CO2 concentration and temperature on tree growth and matter partitioning? How do different tree groups react? Are there any effects on organisms living together with trees? What kinds of models can be used to interpret the results from experiments on trees? This volume is highly recommended for researchers, postdocs, and graduate students in the relevant fields. It is also a valuable resource for undergraduate students, decision-makers in the fields of forest management and environmental protection, and any other scientists who are interested in the effect of global change on ecosystems.

Book Description
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 Description
The response of intra and interspecific variation in photosynthetic acclimation to growth at elevated atmospheric CO2 concentration (600[mu]mol mol-l) in six important grassland species was investigated. Plants were grown in a background sward of Lolium perenne and measurements were made after four years of growth at elevated C{sub a}. Elevated CO2 was maintained using a FACE (Free-Air Carbon Enrichment) system. Significant intra and interspecific variation in acclimation response was demonstrated. The response of adaxial and abaxial stomatal conductance to elevated CO2 was also investigated. The stomatal conductance of both the adaxial and abaxial leaf surfaces was found to be reduced by elevated C{sub a}. Significant asymmetric responses in stomatal conductance was demonstrated in D. glomerata and T. pratense. Analysis of stomatal indices and densities indicated that the observed reductions in stomatal conductance were probably the result of changes in stomatal aperture.

Book Description
The impact of rising levels of greenhouse gases—and the global consequences for crops! Carbon dioxide is a major greenhouse gas that causes global warming and directly impacts every aspect of plant life and indirectly impacts animal and human life. Atmospheric carbon dioxide levels have risen dramatically over the past century, and though this could mean opportunities for better growth and increased yield of certain crops, other factors like weather extremes and changes to plant physiology may mitigate the positive effects. Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide comprehensively analyzes every aspect of crop responses to increasing carbon dioxide as well as their productional significance for the world. Changes in the growth rate and yield of crops are explored, with attention given to the consequences of coming weather changes on production and the expected economic impact. Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide takes the data gleaned from careful research to provide an in-depth vision of the impact of carbon dioxide on global temperatures, plant physiology, and the ecological and economic future of our world. Respected authorities thoroughly discuss the research detailing the complete range of issues from plant growth under increased carbon dioxide levels to the impact of rising air temperatures to the evolving ecophysiological responses within various crops. Extensive references provide opportunities for further research while detailed tables and graphs clearly illustrate data. Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide explores the effects of carbon dioxide enrichment on: plants, crops, and vegetation—is it beneficial? growth, yield, and photosynthetic responses in rice the photosynthetic capacity and productivity of rice under field conditions—and the role of nitrogen fertilization forage and grain nitrogen content potato crops crop responses including interaction with temperature the growth of maize different agricultural systems around the world—such as central and southeastern Europe, northern climates, Sudan, citrus-growing regions, and others the production ecophysiology of Hungarian green pepper and much more! The impending changes in our world make Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide a valuable text for educators and postgraduate students in the field of plant ecology and crop production and an essential resource for researchers in the fields of plant ecology, ecophysiology, agricultural crop production, and environmental sciences.

Book Description
This richly illustrated volume is the first complete atlas of coffee production in Ethiopia, birth-place of coffee drinking and the main home of wild arabica coffee (Coffea arabica). Around 15 million Ethiopians are coffee farmers, and Ethiopia is Africa's largest coffee producer and one of the most important coffee-growing regions of the world, renowned for its diversity of flavour profiles, including those of the celebrated coffees of Harar, Limu, Sidamo, and Yirgacheffe. The aim of the Coffee Atlas of Ethiopia is to inform the reader about the coffee landscape of Ethiopia. It shows where coffee is grown, where the natural coffee forests are located, and where coffee could be grown. The atlas maps are accompanied by information on coffee farming, environment and climate, and a description of the main coffee areas. Also included in the atlas are key coffee origins, coffee towns and coffee delivery centres, as well as other useful items. The atlas can be used to assess the potential and vulnerability for coffee farming in Ethiopia, as well as provide a logistics resource for the coffee sector and those otherwise working with, or interested in, coffee. It is also an essential reference for resource managers.
