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.
A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
Ocean Acidification and Marine Wildlife: Physiological and Behavioral Impacts provides comprehensive knowledge on how decreases in the pH of the world's oceans is affecting marine organisms. The book synthesizes recent findings about the impacts of ocean acidification (OA) on marine animals, covering the physiological and behavioral effects upon marine invertebrates and vertebrates, the potential physiological and molecular mechanism affects, and interactions of OA with other environmental factors. Written by international experts in this research field, this book summarizes new discoveries of OA effects on fertilization, embryonic development, biomineralization, metabolism, immune response, foraging, anti-predation, habitat selection, and the social hierarchy of marine animals. This is an important resource for researchers and practitioners in marine conservation, marine wildlife studies, and climate change studies. In addition, it will serve as a valuable text for marine biology and animal science students. - Examines the impacts of carbon dioxide increases in the world's oceans relating to marine vertebrates and invertebrates - Identifies environmental factors, including climate change and pollution and how they increase the negative effects of ocean acidification - Facilitates a better understanding of ocean acidification effects for conservationism and future prevention
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.

'Marine Conservation Biology' brings together leading experts from around the world to apply the lessons and thinking of conservation biology to marine issues. The contributors cover what is threatening marine biodiversity and what humans can do to recover the biological integrity of the world's oceans.
This book brings together the state of our knowledge on the interactions between climate change and marine biota. It focusses broadly on the environmental stressors during the Anthropocene period; when human activities started to have a significant global impact on earth's geological imprint and ecosystems. This period of rapid change is accompanied by rising carbon dioxide levels, increasing global temperatures, loss of oxygen in aquatic systems, and the fast release of pollutants into the environment among many other environmental stressors originating from large scale human activities, such as widespread overfishing.The Future of Marine Life in a Changing Ocean starts by providing the reader with a brief background on fundamental concepts in ocean science and climate. It then moves on to a brief description of recent changes in marine chemistry such as ocean acidification, a decline in oxygen levels in the oceans, ocean warming, and marine pollution, with some examples of shifts in ecosystem diversity. The chapters discuss these topics in the context of how a changing ocean impacts ecosystem health, the biological carbon pump, the sequestration of carbon dioxide from the surface ocean into the deep sea, and the perceived notion of the ocean's unlimited resilience to maintain its role as a 'carbon reservoir'. Topics include threats to marine diversity, ecosystem function, latitudinal shifts in productivity and diversity, and changes in global cycling of elements such as carbon. It concludes with an analysis of the impact of climate change on food security.Written for undergraduate and graduate students, and researchers in the natural and social sciences, this book provides a science background to study environmental change in marine ecosystems as well as a science framework to study policy, marine law and the economics of climate change. This book is an essential read for anyone hoping to understand key challenges facing our oceans.
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.
This summarises the latest advances in the physiological and ecological responses of marine species to a wide range of potential stressors resulting from current anthropogenic activity, and provides a perspective on future outcomes for some of the most pressing environmental issues facing society today.
