Book Description
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 Description
Over the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa. The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.

Book Description
This book intends to be an alert to the fact that the curve measuring environmental costs against the economic benefits of capitalism has irreversibly entered into a negative phase. The prospect of an environmental collapse has been evidenced by the sciences and the humanities since the 1960s. Today, it imposes its urgency. This collapse differs from past civilizations in that it is neither local nor just civilizational. It is global and occurs at the broadest level of the biosphere, accelerated by the convergence of different socio-environmental crises, such as: Earth energy imbalance, climate change and global warming Sea-level rise Decrease and degradation of forests Collapse of terrestrial and aquatic biodiversity Floods, droughts, wildfires, and extreme weather events Degradation of soils and water resources Increase in pollution caused by fossil fuels and coal Increase in waste production and industrial intoxication The book is divided in two parts. In the first part it presents a comprehensive review of scientific data to show the already visible effects of each of the different environmental crises and its consequences to human life on Earth. In the second part, Luiz Marques critically discusses what he calls the three concentric illusions that prevent us from realizing the gravity of the current socio-environmental crises: the illusion of a sustainable capitalism, the illusion that economic growth is still capable of providing more well-being and the anthropocentric illusion. Finally, Marques argues that "fitting" back into the biosphere will only be possible if we dismantle the expansive socioeconomic gear that has shaped our societies since the 16th century by moving from a Social Contract to a Natural Contract, which takes into account the whole biosphere. According to him, the future society will be post-capitalist or it will not be a complex society, and even perhaps, we must fear, no society at all. “This book is backed up with the latest and best science and has made the complexities understandable for the average reader, all in a context of hope for the future.” - William J.

Book Description
Climate and Conservation presents case studies from around the world of leading-edge projects focused on climate change adaptation-regional-scale endeavors where scientists, managers, and practitioners are working to protect biodiversity by protecting landscapes and seascapes in response to threats posed by climate change. The book begins with an introductory section that frames the issues and takes a systematic look at planning for climate change adaptation. The nineteen chapters that follow examine particular case studies in every part of the world, including landscapes and seascapes from equatorial, temperate, montane, polar, and marine and freshwater regions. Projects profiled range from North American grasslands to boreal forests to coral reefs to Alpine freshwater environments. Chapter authors have extensive experience in their respective regions and are actively engaged in working on climate-related issues. The result is a collection of geographical case studies that allows for effective cross-comparison while at the same time recognizing the uniqueness of each situation and locale. Climate and Conservation offers readers tangible, place-based examples of projects designed to protect large landscapes as a means of conserving biodiversity in the face of the looming threat of global climate change. It informs readers of how a diverse set of conservation actors have been responding to climate change at a scale that matches the problem, and is an essential contribution for anyone involved with large-scale biodiversity conservation.

Book Description
Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.
