Book Description
Now available in paper, this stimulating book concentrates on evolutionary change under environmental stress at levels ranging from the molecular to the biogeographic, with an emphasis on genetic aspects. This approach contrasts with most of the literature of evolutionary biology, as theemphasis here is upon the extreme end of the stress gradient in terms of resistance. Major topics in this interdisciplinary book include the concept of stress and its evolutionary and ecological importance; genetic variation in stress response and the effects of stress on genetic variation; and costs and trade-offs involving stress responses. An approach to stress resistance interms of energetics permits the development of links between genetics, ecology, physiology, and behaviour. The book concludes with applications concerning range expansions of species, conservation strategies, and pollution effects.

Book Description
Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.

Book Description
Not all stress is stressful; instead, it appears that stress in the environment, below the mutation threshold, is essential for many subtle manifestations of population structures and biodiversity, and has played a substantial role in the evolution of life. Intrigued by the behavior of laboratory animals that contradicted our current understanding of stress, the author and his group studied the beneficial effects of stress on animals and plants. The seemingly “crazy” animals demonstrated that several stress paradigms are outdated and have to be reconsidered. The book describes the general stress responses in microorganisms, plants, and animals to abiotic and biotic, to natural and anthropogenic stressors. These stress responses include the activation of oxygen, the biotransformation system, the stress proteins, and the metal-binding proteins. The potential of stress response lies in the transcription of genes, whereas the actual response is manifested by proteins and metabolites. Yet, not all stress responses are in the genes: micro-RNAs and epigenetics play central roles. Multiple stressors, such as environmental realism, do not always act additively; they may even diminish one another. Furthermore, one stressor often prepares the subject for the next one to come and may produce extended lifespans and increased offspring numbers, thus causing shifts in population structures. This book provides the first comprehensive analysis of the ecological and evolutionary effects of stress.

Book Description
This book examines the toxicological and health implications of environmental epigenetics and provides knowledge through an interdisciplinary approach. Included in this volume are chapters outlining various environmental risk factors such as phthalates and dietary components, life states such as pregnancy and ageing, hormonal and metabolic considerations and specific disease risks such as cancer cardiovascular diseases and other non-communicable diseases. Environmental Epigenetics imparts integrative knowledge of the science of epigenetics and the issues raised in environmental epidemiology. This book is intended to serve both as a reference compendium on environmental epigenetics for scientists in academia, industry and laboratories and as a textbook for graduate level environmental health courses.

Book Description
In recent years, scientists have realized that evolution can occur on timescales much shorter than the 'long lapse of ages' emphasized by Darwin - in fact, evolutionary change is occurring all around us all the time. This work provides an authoritative and accessible introduction to eco-evolutionary dynamics, a cutting-edge new field that seeks to unify evolution and ecology into a common conceptual framework focusing on rapid and dynamic environmental and evolutionary change.

Book Description
Although unpredictable and of short duration, periods of extreme environmental stress have been found to occur throughout the entire course of evolution. This book concentrates on the evolutionary changes that take place during these critical periods, when populations are driven to the extreme limits of resistance. Accumulating evidence suggests that it is precisely during such moments that fundamental changes in the natural order of systems are likely, both in terms of species extinctions and bursts of evolutionary activity. This study thus offers much potential for understanding the basic forces underlying the development of life on our planet. The book is necessarily multidisciplinary in approach, with an emphasis on the interaction between ecology, genetics, physiology, and the study of behavior and development. The book concludes with a discussion of the range expansion of species, and insightful observations regarding conservation strategies under rapidly changing conditions, including those created by environmental pollution.

Book Description
Most natural populations intermittently experience extremely stressful conditions. This book discusses how such conditions can cause periods of intense selection, increasing both phenotypic and genetic variation, and allowing organisms with novel characteristics to be first generated and then established in the population. The authors argue that stressful conditions can have a major impact on the environment, backing up their arguments with evidence from the fossil record. They suggest further that, as a consequence, periods of stress must be taken into consideration when long term conservation strategies are planned, particularly as stressful conditions are becoming increasingly prevalent as a result of human activities. This broad overview will be of great interest to students and researchers in the field of evolutionary biology, genetics, ecology, palaeontology and conservation biology.

Book Description
The mechanisms underlying endurance and adaptation to environmental stress factors in plants have long been the focus of intense research. Plants overcome environmental stresses by development of tolerance, resistance or avoidance mechanisms, adjusting to a gradual change in its environment which allows them to maintain performance across a range of adverse environmental conditions. Plant Acclimation to Environmental Stress presents the latest ideas and trends on induced acclimation of plants to environmental stresses under changing environment. Written by experts around the globe, this volume adds new dimensions in the field of plant acclimation to abiotic stress factors. Comprehensive and lavishly illustrated, Plant Acclimation to Environmental Stress is a state-of-the-art guide suited for scholars and researchers working in the field of crop improvement, genetic engineering and abiotic stress tolerance.
