Book Description
A very powerful chronicle of the St. Lawrence River Beluga whales which were hunted to near extinction until given legal protection in 1979, and are now quite literally dying from pollution. Beland (senior research scientist, St. Lawrence National institute of Ecotoxicology) describes the Beluga history, how they live now, the pollution threats to them, and ways in which this kind of tragedy can be prevented in the future, although it looks like it's too late for the Beluga; thus the volume also serves as their elegy. Includes color photographs. Annotation copyright by Book News, Inc., Portland, OR

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
This is an action/adventure story about an undersized baby Beluga Whale named Chuga.

Once there, Chuga makes new friends, faces the challenge of a bully, and finds himself trapped in a life or death situation.The story includes encounters with age-old and dangerous foes in the form of the Black Beasts (Orcas, or Killer Whales), the White Beasts (Polar Bears), people, and each other. With new friends, unexpected curiosities, nature's unyielding certainties, and deadly encounters, we race along to a dramatic and heartwarming conclusion.Full of action and danger, excitement and triumph, it tackles some of the contemporary issues facing our youth today, and shows how our decisions can have a lasting effect on those around us.Though it is intended for a younger audience (middle readers age 7 to 14), parents can delight in sharing this story with their children, and be able to discuss the issues presented.

Book Description
Among all the large whales on Earth, the most unusual and least studied is the narwhal, the northernmost whale on the planet and the one most threatened by global warming. Narwhals thrive in the fjords and inlets of northern Canada and Greenland. These elusive whales, whose long tusks were the stuff of medieval European myths and Inuit legends, are uniquely adapted to the Arctic ecosystem and are able to dive below thick sheets of ice to depths of up to 1,500 meters in search of their prey-halibut, cod, and squid. Join Todd McLeish as he travels high above the Arctic circle to meet: Teams of scientific researchers studying the narwhal's life cycle and the mysteries of its tusk Inuit storytellers and hunters Animals that share the narwhals' habitat: walruses, polar bears, bowhead and beluga whales, ivory gulls, and two kinds of seals McLeish consults logbooks kept by whalers and explorers and interviews folklorists and historians to tease out the relationship between the real narwhal and the mythical unicorn. In Colorado, he visits climatologists studying changes in the seasonal cycles of the Arctic ice. From a history of the trade in narwhal tusks to descriptions of narwhals' vocalizations as heard through hydrophones, Narwhals reveals the beauty and thrill of the narwhal and its habitat, and the threat it faces from a rapidly changing world.

Book Description
Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment. Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.
