Plant Adaptation to Extreme Environments in Drylands


Book Description

Our reprint consists of 13 papers. In the first five papers, the influencing factors of biodiversity and community composition are addressed. In the sixth and seventh papers, the spatial distribution patterns and drivers of arid plants under the background of global climate change are examined. The eighth paper describes leaf stoichiometry in arid zones. The ninth studies the change in carbon allocation depending on plant growth stage and the tenth deals with the use of condensed water by plants. Papers 11-13 look at the relationship between plants and soil.










Plant Adaptation Strategies in Changing Environment


Book Description

This book addresses the crucial aspects of plant adaptation strategies in higher as well as lower plant groups. Stress induced by changing environmental conditions disrupts or alter various physiological and metabolic processes in organisms, however, plants have evolved various defence strategies to cope with external perturbations. The book discusses speciation changes in response to extreme ecological conditions such as cold, heat, aridity, salinity, altitude, incidental UV radiation and high light intensity, which are particularly relevant in the current scenario of global warming. It also explores the effects of human activities and emission of phytotoxic gases. Further, it describes the overall adaptation strategies and the multifaceted mechanisms involved (integrated complex mechanism), ranging from morphological to molecular alterations, focusing on plants’ capabilities to create an inner environment to survive the altered or extreme conditions. This book is a valuable tool for graduate and research students, as well as for anyone working on or interested in adaptation strategies in plants.




Ecophysiology of Economic Plants in Arid and Semi-Arid Lands


Book Description

This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail.




Adaptation of Plants to Water and High Temperature Stress


Book Description

Morphological adaptations to water stress. Physiological adaptations to water stress. Adaptation to high temperature stress. Interaction and integration of adaptations to stress. Breeding and selection for adaptation to stress.




Dryland Ecohydrology


Book Description

Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.




Ecosystems and Human Well-being


Book Description

Ecosystems and Human Well-Being is the first product of the Millennium Ecosystem Assessment, a four-year international work program designed to meet the needs of decisionmakers for scientific information on the links between ecosystem change and human well-being. The book offers an overview of the project, describing the conceptual framework that is being used, defining its scope, and providing a baseline of understanding that all participants need to move forward. The Millennium Assessment focuses on how humans have altered ecosystems, and how changes in ecosystem services have affected human well-being, how ecosystem changes may affect people in future decades, and what types of responses can be adopted at local, national, or global scales to improve ecosystem management and thereby contribute to human well-being and poverty alleviation. The program was launched by United National Secretary-General Kofi Annan in June 2001, and the primary assessment reports will be released by Island Press in 2005. Leading scientists from more than 100 nations are conducting the assessment, which can aid countries, regions, or companies by: providing a clear, scientific picture of the current sta







Dryland Opportunities


Book Description

Drylands cover 41 percent of the earth' s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.
