Book Description
An aerial survey was conducted for six narwhal summering aggregations (hereafter referred to as stocks) in the Canadian High Arctic in August 2013. This is the first time that a survey counted all of the Canadian High Arctic narwhal stocks during one summer, and the first time for narwhals in Jones Sound and Smith Sound. The total estimate for the Canadian High Arctic was 141,909 (Coefficient of Variation, CV by stock ranged from 20 to 65%) narwhals. This Canadian Science Advisory Secretariat (CSAS) Science Advisory Report provides updated scientific advice regarding Total Allowable Landed Catch (TALC) levels for each of the Baffin Bay narwhal stocks, and for narwhals in Smith and Jones Sounds.

Addis Ababa Principles and Guidelines for the Sustainable Use of Biodiversity

Pages : 21
Book Description
The Addis Ababa principles and guidelines for the sustainable use of biodiversity provide a framework for assisting governments, indigenous and local communities, resource managers, the private sector and other stakeholders, about how to ensure that their uses of biological diversity will not lead to its long-term decline. The practical principles in most instances apply to both consumptive and non-consumptive uses of biodiversity components. They take into account requirements related to policies, laws, and regulations; management of biological diversity; socio-economic conditions; and information, research, and education.

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.
