DOWNLOAD EBOOKMarine 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.

DOWNLOAD EBOOKMarine mammals command a high level of public attention, reflected in specific legislation for their protection and management in many countries. They also present particular challenges to ecologists and conservation biologists. They are mostly difficult to observe, they occupy an environment that is vast in its three dimensional extent, there are often perceived conflicts between marine mammals and people, and furthermore several species are now close to extinction. Marine mammals have some intriguing features in their biology - the ability to dive to crushing depths, to perform breath-hold dives that defy our current understanding of mammalian physiology, and many have an ability to hunt down prey using sophisticated sonar that we are only just beginning to understand. Many species also have complex social structures. We still have much to learn about these extraordinary animals so a comprehensive and authoritative overview of current methodology is now timely. The intention of this book is both to summarize the state-of-the-art and to encourage innovation and further progress in this research field.
