Available in PDF, EPUB and Kindle. Book excerpt: 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 The seemingly “crazy” animals demonstrated that several stress paradigms are outdated and have to be reconsidered.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.

Download or read book Environmental Stress Adaptation and Evolution written by K. Bijlsma and published by Birkhäuser. This book was released on 2013-03-08 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Evolutionary Genetics and Environmental Stress written by Ary A. Hoffmann and published by Oxford University Press on Demand. This book was released on 1993 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Organism and Environment written by Sonia E. Sultan and published by OUP Oxford. This book was released on 2015-09-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, advances in both molecular developmental biology and evolutionary ecology have made possible a new understanding of organisms as dynamic systems interacting with their environments. This innovative book synthesizes a wealth of recent research findings to examine how environments influence phenotypic expression in individual organisms (ecological development or 'eco-devo'), and how organisms in turn alter their environments (niche construction). A key argument explored throughout the book is that ecological interactions as well as natural selection are shaped by these dual organism-environment effects. This synthesis is particularly timely as biologists seek a unified contemporary framework in which to investigate the developmental outcomes, ecological success, and evolutionary prospects of organisms in rapidly changing environments. Organism and Environment is an advanced text suitable for graduate level students taking seminar courses in ecology, evolution, and developmental biology, as well as academics and researchers in these fields.
Download or read book Extreme Environmental Change and Evolution written by Ary A. Hoffmann and published by Cambridge University Press. This book was released on 1997-07-10 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Morphogenesis Environmental Stress and Reverse Evolution written by Jean Guex and published by Springer. This book was released on 2020-08-27 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution. Capacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of ‘reverse evolution’ by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.

This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: September 1987, the Faculty Biology of the Vrije Universiteit, Amsterdam commemorated the fact that Prof. Dr. Wilfried Hans Otto Ernst had been active as a scientist for 25 years. This period of 25 years of scientific research started at the Institut flir Angewandte Botanik (Institute of Applied Botany) of the University of Munster, FRG. In 1965 he completed his Ph. D. thesis, entitled "Untersuchungen der Schwermetallpflanzengesellschaften Mitteleuropas unter Einschluss der Alpen. " He was appointed full Professor at the Department of Ecology of the Vrije Universiteit, Amsterdam in 1973. On the occasion of his 25th anniversary as a scientist, a promise was made, though in covert terms, which we could not redeem at that time. The promise held to offer Prof. Ernst a book, in which his former and present staffmembers, Ph. D. students and colle ages should write a review about their specialism concerning a central theme. Now, at the beginning of 1990 we consider the chapters of "Ecological Responses to Environmental Stresses" to be completed. The book reflects the wide range of research approaches that has been initiated and organized by Wilfried Ernst. The editors hope to have attained the primary aim of the production of the book of friends, that is to gather relevant papers of staff-members and colleagues of Wilfried Ernst. The title of the book "Ecological Responses to Environmental Stresses" covers the majority of the chapters included.
Download or read book Stress written by Alan H. Bittles and published by Springer. This book was released on 2016-07-27 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: The collected papers in this volume cover the effects of environmental stress under a biological and energetic model. Examples are taken from fossil and living animal populations, and from outlier human populations and traditional societies. These examples indicate that stress increases energy demands and so reduces reproductive fitness. A wide range of stressful situations also are analyzed under the less stringent conditions experienced by modern human populations, when cultural factors assume importance. These emphasize the interaction between genetic, physiological, psychological and social factors in everyday life and in clinical settings.
Download or read book Environmentalism An Evolutionary Approach written by Douglas Spieles and published by Routledge. This book was released on 2017-12-04 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The premise of this book is that our environmental dilemmas are products of biological and sociocultural evolution, and that through an understanding of evolution we can reframe debates of thought and action. The purpose is to explain the wide variety of environmental worldviews, their origins, commonalities, points of contention, and their implications for the modern environmental movement. In three parts covering the origins, evolution and future of environmentalism, it offers instructors and students a framework on which to map theory, case studies and classical literature. It is shown that environmentalism can be described in terms of six human values—utility, stability, equity, beauty, sanctity, and morality—and that these are deeply rooted in our biological and cultural origins. In building this case the book draws upon ecology, philosophy, psychology, history, biology, economics, spirituality, and aesthetics, but rather than consider these all independently it integrates them to craft a mosaic narrative of our species and its home. From our evolutionary origins a story emerges; it is the story of humankind, how we have come to threaten our own existence, and why we seem to have such difficulty in acting together to ensure our common future. Understanding our environmental problems in evolutionary terms gives us a way forward. It suggests an environmentalism in which material views of human life include spirituality, in which our anthropocentric behaviors incorporate ecological function, and in which environmental problems are addressed by the intentional relation of humans to the nonhuman world and to one another. Aimed at students taking courses in environmental studies, the book brings clarity to a complex and, at times, confusing array of ideas and concepts of environmentalism.
Download or read book Plant Ecology and Evolution in Harsh Environments written by Nishanta Rajakaruna and published by Nova Science Publishers. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harsh environments found around the world harbour unique organisms adapted to extreme ranges in climatic, edaphic, and other environmental variables. Whether they occur in extreme climates such as alpine summits or inland deserts, in habitats frequently disturbed by fire or floods, or on edaphic islands created by unique geologies or anthropogenic contamination, the adaptations demonstrated by organisms found in such environments shed light on basic and applied aspects of ecology and evolution. This volume brings together current research on plants, fungi and microbes from harsh environments to reveal underlying patterns and common themes of these especially challenging habitats. Topics include the role of bedrock geochemistry and soil evolutionary processes in generating extreme habitats; the biology, ecology, and evolution of non-vascular and vascular plants, lichens, herbivores and pathogens, mycorrhizal fungi, and other beneficial microbes found in extreme environments. Habitats discussed in the book include alpine and arctic settings, fire-prone Mediterranean climates, serpentine outcrops, gypsum soils, metal-rich mine tailings, and saline soils. In addition to summarizing current research, we highlight new tools and emerging techniques in high-throughput phenotyping, genomics, and phylogenetics that are being used to develop our understanding of evolution in harsh environments. We also emphasise results gained from classical ecological approaches which have allowed us to examine adaptation to and evolution in harsh environments. In addition to discussing basic research, we cover applied work focusing on the threats posed by climate change and other anthropogenic impacts as well as efforts to restore and protect extreme habitats and the unique organisms they harbour. Finally, we discuss the uses of plant species found in extreme environments for agriculture and biotechnology, including the relatively new fields of phytoremediation and phytomining. The work highlighted in this volume demonstrates what these species and their environments have taught us about ecological and evolutionary theory, conservation, and restoration: knowledge that can be applied well beyond the habitats and species described in this book.

Download or read book Evolutionary Genetics and Environmental Stress written by Ary A. Hoffmann and published by Oxford University Press, USA. This book was released on 1991 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Oxidative Stress and Hormesis in Evolutionary Ecology and Physiology written by David Costantini and published by Springer Science & Business Media. This book was released on 2014-03-27 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses oxidative stress and hormesis from the perspective of an evolutionary ecologist or physiologist. In the first of ten chapters, general historical information, definitions, and background of research on oxidative stress physiology, hormesis, and life history are provided. Chapters 2-10 highlight the different solutions that organisms have evolved to cope with the oxidative threats posed by their environments and lifestyles. The author illustrates how oxidative stress and hormesis have shaped diversity in organism life-histories, behavioral profiles, morphological phenotypes, and aging mechanisms. The book offers fascinating insights into how organisms work and how they evolve to sustain their physiological functions under a vast array of environmental conditions.
