Book Synopsis Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals by : National Academies of Sciences, Engineering, and Medicine
Download or read book Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-05-04 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.
Book Synopsis Multiple Stressors by : S. M. Swanson
Download or read book Multiple Stressors written by S. M. Swanson and published by IWA Publishing. This book was released on 2004-07-31 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a pressing need for developing and testing a general set of theories in order to provide a confident basis for prediction of multiple stressor effects. Confident prediction is central to confident decision making in water pollution control. Consequently, WERF commissioned this study, which has as its goal to provide a study design based on good science that helps establish a general, conceptual approach to multiple stressors. The objectives addressed in this report are: (1) review and critique the existing body of knowledge for multiple stressors; (2) develop a searchable, annotated bibliography of multiple stressor research; and, (3) identify gaps in the body of knowledge. A rigorous, theoretical basis for the prediction of multiple stressor effects could not be developed from the literature on experimental studies of multiple stressor effects in aquatic ecosystems. Despite the wealth of observational data, the existence of several useful tools for interpretation of cause/effect relationships (including formal Stressor Identification methods), and the studies reviewed in this report, there are no tools that allow a confident, a priori, prediction of ecosystem response to multiple stressors. The current literature provides, at best, a series of site-specific glimpses of the response of ecological communities and ecosystems to multiple stressors. There is seldom, if ever, any reference to a more generalized model of multiple stressor effects apart from the discussion of the expectations regarding additivity versus synergism. Many articles that purport to be multiple stressor studies do not go beyond an inventory of the various stresses and upsets affecting the ecosystem, without attempting to assess the interactions among them.
Book Synopsis Multiple Stressors: A Challenge for the Future by : Carmel Mothersill
Download or read book Multiple Stressors: A Challenge for the Future written by Carmel Mothersill and published by Springer Science & Business Media. This book was released on 2007-08-20 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxiclogical risk from multiple stressors covers any situation where org- isms are exposed to a combination of environmental stressors. These include physical and chemical pollutants as well as other stressors such as parasites and environmental impact (e. g. , climate change or habitat loss). The combi- tion of stressors can result in increased risk to organisms (either additive or synergistic effects) or decreased effects (protective or antagonistic effects). The multiple stressor challenge is an international, multi-disciplinary problem requiring an international, multi-disciplinary approach. The c- rent approach to multiple stressors is to examine one stressor at a time and assume additivity. Little work has been done on combinations of stressors such that potential interactions can be determined. The problem is very complex. Multiple stressors pose a whole spectrum of challenges that range from basic science to regulation, policy and gove- ance. The challenges raise fundamental questions about our understanding of the basic biological response to stressors, as well as the implications of those uncertainties in environmental risk assessment and management. In addition to the great breadth, there is also great depth in the research ch- lenges, largely due to the complexity of the issues. From a basic science point of view, many of the mechanisms and processes under investigation are at the cutting edge of science — involving new paradigms such as genomic ins- bility and bystander effects.
Book Synopsis Ecotoxicology, Ecological Risk Assessment and Multiple Stressors by : Gerassimos Arapis
Download or read book Ecotoxicology, Ecological Risk Assessment and Multiple Stressors written by Gerassimos Arapis and published by Springer Science & Business Media. This book was released on 2006-01-12 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of ecotoxicology and the practice of ecological risk assessment are evolving rapidly. Ecotoxicology as a subject area came into prominence in the 1960s after the publication of Rachel Carson's book on the impact of pesticides on the environment. The rise of public and scientific concern for the effects of chemical pollutants on the environment in the 1960s and 1970s led to the development of the discipline of ecotoxicology, a science that takes into account the effects of chemicals in the context of ecology. Until the early 1980s, in spite of public concern and interest among scientists, the assessment of ecological risks associated with natural or synthetic pollutants was not considered a priority issue by most government. However, as the years passed, a better understanding of the importance of ecotoxicology emerged and with it, in some countries, the progressive formalization of an ecological risk assessment process. Ecological risk assessment is a conceptual tool for organizing and analyzing data and information to evaluate the likelihood that one or more stressors are causing or will cause adverse ecological effects. Ecological risk assessment allows risk managers to consider available scientific information when selecting a course of action, in addition to other factors that may affect their decision (e. g. , social, legal, political, or economic). Ecological risk assessment includes three phases (problem formulation, analysis, and risk characterization).
Book Synopsis Climate Action by : Walter Leal Filho
Download or read book Climate Action written by Walter Leal Filho and published by Springer. This book was released on 2019-11-10 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume addresses SDG 13, "Take urgent action to combat climate change and its impacts", and contains the description of a range of terms, which allows a better understanding and fosters knowledge. Climate change is a threat to development with unprecedented impacts. Urgent action to combat climate change and development of integrated strategies on climate change mitigation and adaptation and sustainable development are critical for a sustainable future. Concretely, the defined targets are: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries Integrate climate change measures into national policies, strategies and planning Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning Implement the commitment undertaken by developed-country parties to the United Nations Framework Convention on Climate Change to a goal of mobilizing jointly $100 billion annually from all sources to address the needs of developing countries in the context of meaningful mitigation actions and transparency on implementation and fully operationalize the Green Climate Fund through its capitalization as soon as possible Promote mechanisms for raising capacity for effective climate change-related planning and management in least developed countries and small island developing states, including focusing on women, youth and local and marginalized communities Editorial Board Anabela Marisa AzulDragan NonicFederica DoniJeff BirchallLuis R.

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 484 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 Understanding Multiple Environmental Stresses by : National Research Council
Download or read book Understanding Multiple Environmental Stresses written by National Research Council and published by National Academies Press. This book was released on 2007-05-25 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research of the last decade has demonstrated that ecosystems and human systems are influenced by multiple factors, including climate, land use, and the by-products of resource use. Understanding the net impact of a suite of simultaneously occurring environmental changes is essential for developing effective response strategies. Using case studies on drought and a wide range of atmosphere-ecosystem interactions, a workshop was held in September 2005 to gather different perspectives on multiple stress scenarios. The overarching lesson of the workshop is that society will require new and improved strategies for coping with multiple stresses and their impacts on natural socioeconomic systems. Improved communication among stakeholders; increased observations (especially at regional scales); improved model and information systems; and increased infrastructure to provide better environmental monitoring, vulnerability assessment, and response analysis are all important parts of moving toward better understanding of and response to situations involving multiple stresses. During the workshop, seven near-term opportunities for research and infrastructure that could help advance understanding of multiple stresses were also identified.
Book Synopsis Chemical Mixtures and Combined Chemical and Nonchemical Stressors by : Cynthia V. Rider
Download or read book Chemical Mixtures and Combined Chemical and Nonchemical Stressors written by Cynthia V. Rider and published by Springer. This book was released on 2018-02-16 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, both basic and advanced concepts are discussed for considering mixtures from initial exposure characterization through evaluation of risk associated with combined exposures. This book will provide an introduction to key issues and multiple options for evaluating both the toxicity of mixtures as well as the risk associated with exposure to mixtures. Additionally, promising tools adapted from other disciplines will be discussed in the context of mixtures toxicology and risk assessment. Finally, the discussion will move beyond chemical mixtures to address incorporating non-chemical stressors into toxicity studies and cumulative risk assessments. Although exposure to multiple chemical and non-chemical stressors is the rule, not the exception, consideration of mixtures in toxicology and risk assessment continues to be a significant challenge. This book will be an essential resource for researchers and professionals in the fields of toxicology, epidemiology, exposure science, risk assessment, and statistics.
Book Synopsis Polyextremophiles by : Joseph Seckbach
Download or read book Polyextremophiles written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2013-05-13 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many Microorganisms and some macro-organisms can live under extreme conditions. For example, high and low temperature, acidic and alkaline conditions, high salt areas, high pressure, toxic compounds, high level of ionizing radiation, anoxia and absence of light, etc. Many organisms inhabit environments characterized by more than one form of stress (Polyextremophiles). Among them are those who live in hypersaline and alkaline, hot and acidic, cold/hot and high hydrostatic pressure, etc. Polyextremophiles found in desert regions have to copy with intense UV irradiation and desiccation, high as well as low temperatures, and low availability of water and nutrients. This book provides novel results of application to polyextremophiles research ranging from nanotechnology to synthetic biology to the origin of life and beyond.

Book Synopsis Stress, Risk, and Resilience in Children and Adolescents by : Robert J. Haggerty
Download or read book Stress, Risk, and Resilience in Children and Adolescents written by Robert J. Haggerty and published by Cambridge University Press. This book was released on 1996-09-28 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many children's behavioral problems have multiple causes, and most children with one problem behavior also have others. The co-occurence and interrelatedness of risk factors and problem behavior is certainly an important area of research. This volume recognizes the complexity of the developmental processes that influence coping and resilience and the roles sociocultural factors play. The contributors focus on four themes that have emerged in the study of risk and coping over the past decade: interrelatedness of risk and problems, individual variability in resilience and susceptibility to stress, processes and mechanisms linking multiple stressors to multiple outcomes, and interventions and prevention. Psychologists, pediatricians, and others involved in the research or care of children will take great interest in this text.
Book Synopsis Organizational Stress Around the World by : Kajal A. Sharma
Download or read book Organizational Stress Around the World written by Kajal A. Sharma and published by Routledge. This book was released on 2021-01-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress is defined as a feeling experienced when a person perceives that demands exceed the personal and social resources the individual is able to mobilize. It can occur due to environmental issues, such as a looming work deadline, or psychological, for example, persistent worry about familial problems. While the acute response to life-threatening circumstances can be life-saving, research reveals that the body’s stress response is largely similar when it reacts to less threatening but chronically present stressors such as work overload, deadline pressures and family conflicts. It is proffered that chronic activation of stress response in the body can lead to several pathological changes such as elevated blood pressure, clogging of blood vessels, anxiety, depression, and addiction. Organizational Stress Around the World: Research and Practice aims to present a sound theoretical and empirical basis for understanding the evolving and changing nature of stress in contemporary organizations. It presents research that expands theory and practice by addressing real-world issues, across cultures and by providing multiple perspectives on organizational stress and research relevant to different occupational settings and cultures. Personal, occupational, organizational, and societal issues relevant to stress identification along with management techniques/approach to confront stress and its associated problems at individual and organizational level are also explored. It will be of value to researchers, academics, practitioners, and students interested in stress management research.
Book Synopsis Recognition and Alleviation of Distress in Laboratory Animals by : National Research Council
Download or read book Recognition and Alleviation of Distress in Laboratory Animals written by National Research Council and published by National Academies Press. This book was released on 2008-04-10 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific advances in our understanding of animal physiology and behavior often require theories to be revised and standards of practice to be updated to improve laboratory animal welfare. This new book from the Institute for Laboratory Animal Research (ILAR) at the National Research Council, Recognition and Alleviation of Distress in Laboratory Animals, focuses on the stress and distress which is experienced by animals when used in laboratory research. This book aims to educate laboratory animal veterinarians; students, researchers, and investigators; animal care staff, as well as animal welfare officers on the current scientific and ethical issues associated with stress and distress in laboratory animals. It evaluates pertinent scientific literature to generate practical and pragmatic guidelines. Recognition and Alleviation of Distress in Laboratory Animals focuses specifically on the scientific understanding of the causes and the functions of stress and distress, the transformation of stress to distress, and the identification of principles for the recognition and alleviation of distress. This book discusses the role of humane endpoints in situations of distress and principles for the minimization of distress in laboratory animals. It also identifies areas in which further scientific investigation is needed to improve laboratory animal welfare in order to adhere to scientific and ethical principles that promote humane care and practice.
