Book Synopsis Environmental Stress and Behavioural Adaptation by : John Davenport
Download or read book Environmental Stress and Behavioural Adaptation written by John Davenport and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally agreed that animal life originated in the sea and that adaptive radiation subsequently led to the colonisaHon of other environments - shores and estuaries, streams and lakes, bog, mountain and desert. In their invasion of these habitats animals left the equable, relatively stabl.e surroundings of the open sea and subjected themselves to the rigours of temperature fluctuations and extremes, a variety of ionic backgrounds, areas of depleted oxygen or the possibility of aerial exposure and potential desiccation. The spur for this radiation presumably lay in the prize of access to unexploited habitats and sources of energy. The survival of these more adventurous species has depended upon them evolving mechanisms to protect the integrity of their cellular constituents. Protoplasm can only exist within physiochemical limits which are quite narrow for each species. Water activity, salt and gas concentrations and temperature all have to be appropriate for enzyme catalysed processes to function properly within cells. Except in the open sea, environmental conditions regularly vary outside these limits. To take a familiar example; humans can only remain conscious (and hence functional) if their core (Le. deep tissues - brain, heart, liver, etc.) body temperature is maintained between about 30 and 43°C.
Book Synopsis Environmental Stress by : Lawrence Folinsbee
Download or read book Environmental Stress written by Lawrence Folinsbee and published by Elsevier. This book was released on 2012-12-02 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Stress: Individual Human Adaptations is the result of a symposium where scientists addressed questions about individual variability in response to different environments. The symposium aimed to create more interest in the roles of age, gender, genetic heritage, and other individual differences in response to various environmental stressors. The book is divided into five sections, each dealing with one aspect of environmental stress. These are: heat stress, air pollution, work physiology (exercise), cold stress, and altitude. Circulatory adaptations to heat and exercise are discussed in the heat section while studies of sleeping patterns associated with high altitude hypoxia are tackled in the section of altitude. In the section of air pollution, the different effects of pollutants such as carbon monoxide and sulfuric acid are tackled. This text will be very useful to students and scientists in many fields such as medicine, physiological sciences, biophysics, and environmental health.

Book Synopsis Environmental Stress, Adaptation and Evolution by : K. Bijlsma
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.

Book Synopsis The Promise of Adolescence by : National Academies of Sciences, Engineering, and Medicine
Download or read book The Promise of Adolescence written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-07-26 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Book Synopsis Stress Ecology by : Christian E.W. Steinberg
Download or read book Stress Ecology written by Christian E.W. Steinberg and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 480 pages. 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.
Book Synopsis Environmental Stress and Amelioration in Livestock Production by : Veerasamy Sejian
Download or read book Environmental Stress and Amelioration in Livestock Production written by Veerasamy Sejian and published by Springer Science & Business Media. This book was released on 2012-06-05 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the importance of livestock to the global economy, there is a substantial need for world-class reference material on the sustainable management of livestock in diverse eco-regions. With uncertain climates involving unpredictable extreme events (e.g., heat, drought, infectious disease), environmental stresses are becoming the most crucial factors affecting livestock productivity. By systematically and comprehensively addressing all aspects of environmental stresses and livestock productivity, this volume is a useful tool for understanding the various intricacies of stress physiology. With information and case studies collected and analyzed by professionals working in diversified ecological zones, this book explores the influence of the environment on livestock production across global biomes. The challenges the livestock industry faces in maintaining the delicate balance between animal welfare and production are also highlighted.
Book Synopsis Struggle of Life by : Martial Rossignol
Download or read book Struggle of Life written by Martial Rossignol and published by . This book was released on 1998 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Life emprisons stress and puts it to work. It often does so by symbiosis. Struggle is a property of life. This book presents Life as a struggle to bring the order of Mendel's Laws of heredity. The physical world tends to run out of useful energy like an old-fashioned clock. The secret of Life is, that it brings order where useful energy has gone, by a process called adaptation. This struggle of life so fashions biodiversity at all levels. Many decades of long-term experiments in test-tubes, long-term study of oceans and climates and forest ecosystem research allowed the authors to compare adaptation of life, from submicroscopic nucleotides to huge ecosystems. The sun's atomic clock beats the rhythm of environmental stress. Behaviour, rhythm and architecture were studied and explained at all levels, from molecule to plant or animal and to ecosystems. All evolution in Life follows pathways of a few steps only, joined by `biological clasps '. A clasp is like a coded biological lock at the end of a chain. A clasp opens or closes each half-path around the DNA helix., A meristem-with-leaf ('leaf-plus') opens or closes the pathway of shoot growth in plants, a ` minimal axis ' allows or blocks branching, perhaps ` homeotic genes ' in animals possess clasps. ` Critical eco-units ' stop or start ecosystem succession. Adaptation to stress requires a change of the code of the lock, that is a changed clasp, and so produces new instructions for new, adapted development. Codes are changed by plasmid transfer in DNA, meristem differentiation in plants, selective activation of seeds and eggs in mini-ecosystems. The sheer number of processes causes development to be complex and fuzzy. The struggle of Life has no mechanical precision. It creates similar but not quite the same, new, unexpected, diverse places for new, diverse structures and organisms to grow."--Site web www.nhbs.com.

Book Synopsis Behavioral Adaptation to Intertidal Life by : Guido Chelazzi
Download or read book Behavioral Adaptation to Intertidal Life written by Guido Chelazzi and published by Springer. This book was released on 1988 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Research Workshop on "Behavioural Adaptation to Intertidal Life" held in Castiglioncello, Italy (May, 1987) was attended by 50 participants, most of whom presented requested lectures. It was perhaps the first time that specialists of various animal groups, from cnidarians to birds, were able to meet and discuss the importance of behavioural adaptation to this peculiar, sometimes very harsh environment. But the taxonomic barrier is not the only one which the meeting attemped to over come. Lately, the research on intertidal biology has spread from pure taxonomy and static analysis of community structure to such dynamic aspects as intra- and interspecific relationships, and physiological mechanisms aimed at avoiding stress and exploitation of limited-resources. This increasing interest stems not only from an inclination for this particular ecological system and some of its typical inhabitants, but also from the realization that rocky and sandy shore communities are suitable models for testing and improving some global theories of evolutionary biology, behavioural ecology and sociobiology. The number of eco-physiological and eco-ethological problems emerging from the study of intertidal animals is fascinatingly large and a complete understanding of this environment cannot be reached using a strictly "reductionistic" or a pure "holistic" approach.
Book Synopsis Climate Change Impact on Livestock: Adaptation and Mitigation by : Veerasamy Sejian
Download or read book Climate Change Impact on Livestock: Adaptation and Mitigation written by Veerasamy Sejian and published by Springer. This book was released on 2015-03-31 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses in detail both livestock’s role in climate change and the impacts of climate change on livestock production and reproduction. Apart from these cardinal principles of climate change and livestock production, this volume also examines the various strategies used to mitigate livestock-related GHG emissions, and those which can reduce the impacts of climate change on livestock production and reproduction. Presenting information and case studies collected and analyzed by professionals working in diversified ecological zones, the book explores the influence of climate change on livestock production across the globe. The most significant feature of this book is that it addresses in detail the different adaptation strategies and identifies targets for different stakeholders in connection with climate change and livestock production. Further, it puts forward development plans that will allow the livestock industries to cope with current climate changes and strategies that will mitigate the effects by 2025. Lastly, it provides researchers and policymakers several researchable priorities to help develop economically viable solutions for livestock production with less GHG emissions, promoting a cleaner environment in which human beings and livestock can live in harmony without adverse effects on productivity. Given that livestock production systems are sensitive to climate change and at the same are themselves a contributor to the phenomenon, climate change has the potential to pose an increasingly formidable challenge to the development of the livestock sector. However, there is a dearth of scientific information on adapting livestock production to the changing climate; as such, well-founded reference material on sustaining livestock production systems under the changing climate scenarios in different agro-ecological zones of the world is essential. By methodically and extensively addressing all aspects of climate change and livestock production, this volume offers a valuable tool for understanding the hidden intricacies of climatic stress and its influence on livestock production.

Book Synopsis Human Behavior and Environment by : Irwin Altman
Download or read book Human Behavior and Environment written by Irwin Altman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers comprising this second volume of Human Behavior and the Environment represent, as do their predecessors, a cross section of current work in the broad area of problems dealing with interrelation ships between the physical environment and human behavior, at both the individual and the aggregate levels. Considering the two volumes as a unit, we have included papers covering a broad spectrum of problems ranging from the theoretical to the applied, and from the disciplinary-based to the interdisciplinary and professional. Approxi mately half of the papers are written by psychologists, with the remainder coming, in part, from such other disciplines as sociology, geography, and from such diverse applied and professional fields as natural recreation, landscape architecture, urban planning, and opera tions research. The volumes thus provide an overview of work on current topical problems. Yet, as the field is developing, specialization is inevitably increasing apace, and the editors as well as the publisher have become convinced of the desirability for futu're volumes in this series to be organized along topical lines, with successive volumes devoted to different aspects of this rather sprawling field. Thus, Volume 3, currently in the planning stage, will be devoted exclusively to the interaction of children with the physical environment, considered from diverse viewpoints, again including authors from diverse fields of specialization.
Book Synopsis Sheep Production Adapting to Climate Change by : Veerasamy Sejian
Download or read book Sheep Production Adapting to Climate Change written by Veerasamy Sejian and published by Springer. This book was released on 2017-06-20 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a compilation of the latest findings from reputed researchers around the globe, covering in detail climate change and its effects on sheep production. In the current global climate change scenario, information related to its impact on livestock agriculture is lacking. The negative impacts of climate change are already being felt by all livestock species. Further, the mitigation and amelioration strategies that are applicable for one species may not hold true for another. As such, concerted research efforts are needed to identify species-specific strategies for mitigation and adaptation. With that goal in mind, this book is the first of its kind to gather comprehensive information pertaining to the impact of climate change on various aspects of sheep production. It also sheds light on the role of sheep with regard to the global greenhouse gas pool. The book highlights the status quo of sheep production from climate change perspectives and projects the significance of adapting future sheep production to the challenges posed by climate change. It addresses in detail the various adaptations, methane mitigation and amelioration strategies needed to sustain sheep production in the future. In addition, the book presents development plans and policies that will allow the sheep industry to cope with current climate changes and strategies that will lessen future impacts. Bringing together essential information prepared by world-class researchers hailing from different agro-ecological zones, this book offers a unique resource for all researchers, teachers and students associated with sustaining the sheep production in the face of global change.
Book Synopsis Energetics and Human Information Processing by : G.M. Hockey
Download or read book Energetics and Human Information Processing written by G.M. Hockey and published by Springer Science & Business Media. This book was released on 1986-09-30 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central theme of this book is the role of energetical factors in the regulation of human information processing activity. This is a restatement of one of the classic problems of psychology - that of acc ounting for motivational or intensive aspects of behaviour, as opposed to structural or directional aspects. The term "energetics" was first used in the 1930's by Freeman, Duffy and others, following Cannon's energy mobilization view of emotion and motivation. The original concept had a limited life, probably because of its unnecessary focus on relativ ely peripheral processes, but it provided the foundations for the con cepts of "arousal" and "activation" which became the popular motivational constructs of the 1950's and 1960's. Now, these too are found wanting. The original assumptions of a unitary, non-specific process based on activation of the brain stem reticular formation have been shown to be misleading. Current work in neurobiology has demonstrated evidence of discrete neurotransmitter systems having quite specific information processing functions, and central roles in the regulation of behaviour. Even the venerable curvilinear relationship between motivation and per formance (the Yerkes-Dodson law) has been shown to be, at best, an unhelpful oversimplification. On a different front psychophysiologists have found complex patterns in the response of different bodily systems to external stressors and to task demands.
