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 global atmospheric concentration of CO2 has increased by more than 30percent since the industrial revolution. Although the stimulating effects of elevated CO2 (eCO2) on plant growth and primary productivity have been well studied, its influences on belowground microbial communities are poorly understood and controversial. In this study, we showed a significant change in the structure and functional potential of soil microbial communities at eCO2 in a grassland ecosystem, the BioCON (Biodiversity, CO2 and Nitrogen) experimental site (http://www.biocon.umn.edu/) using a comprehensive functional gene array, GeoChip 3.0, which contains about 28,0000 probes and covers approximately 57,000 gene variants from 292 functional gene families involved in carbon, nitrogen, phosphorus and sulfur cycles as well as other functional processes. GeoChip data indicated that the functional structure of microbial communities was markedly different between ambient CO2 (aCO2) and eCO2 by detrended correspondence analysis (DCA) of all 5001 detected functional gene probes although no significant differences were detected in the overall microbial diversity. A further analysis of 1503 detected functional genes involved in C, N, P, and S cycles showed that a considerable portion (39percent) of them were only detected under either aCO2 (14percent) or eCO2 (25percent), indicating that the functional characteristics of the microbial community were significantly altered by eCO2. Also, for those shared genes (61percent) detected, some significantly (p

Book Description
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 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.
