Download Toxicology of Marine Mammals Book in PDF, ePub and Kindle
The activities of modern society have unleashed a range of toxic chemicals into the global environment. Many of these toxicants are now being detected in increasing quantities in the tissues of marine mammals, most notably in top predators who acquire relatively large amounts of toxic chemicals by ingesting contaminated prey.

Download Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals Book in PDF, ePub and Kindle
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.

Download Persistent Pollutants in Marine Ecosystems Book in PDF, ePub and Kindle
This new volume from the SETAC (Society of Environmental Toxicology and Chemistry) Special Publications Series examines the phenomenon of persistent pollutants in the seas and oceans. Unlike the highly visible and obvious effects caused by oil, certain chemicals have unseen but long-term and far-reaching effects on the marine ecosystem. They often have long half-lives, are carried great distances and pass easily through the food chain from prey to predator. The behaviour and effects of these persistent pollutants on each type of marine animal (invertebrates, vertebrates, fish, mammals and fish-eating birds) are described. A final overview draws the observations and conclusions together presenting a work that provides a foundation for understanding the behaviour of persistent pollutants in the marine environment.

Download Pollutant Studies In Marine Animals Book in PDF, ePub and Kindle
This volume attempts to summarize the joint efforts of a group of workers who developed systems for analysing marine pollution for use with marine animals and then use these systems to monitor certain select marine populations. Approach taken is to seek pollutant-induced changes in metabolite (e.g. glutathione, ascorbate) concentrations, in hormone concentrations, in enzymes associated with pollutant metabolism (e.g. the cytochrome P-450 mixed-function oxidase system), in immunological capacity and in cellular morphology. The work reported here details the specific methods used and summarizes the results of measurement of the parameters in both pristine and exposed animals. Not all systems exhibited changes in response to the pollutants tested; these systems are also discussed here to help others avoid these potential, but insensitive, markers.

Download Biology of Marine Mammals Book in PDF, ePub and Kindle
Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.
