After travel through Alaska during the Second World War, in 1947 I went to Barrow with a very lively group of biologists. From their productive research developed the Arctic Research Laboratory. While we examined the rather surpris ingly modest metabolic rates of arctic warmblooded animals in cold, PER SCHO LANDER proposed and then carried out measurements of metabolism of some tropi cal animals in Panama. The differences could be formulated to show the basis of adaptation to arctic cold and to tropical warmth. Imagination and logic were required to formulate the comparison so that it could become a part of science, but the essential measurements were derived from animals and plants in their own arctic and tropical environments. Characteristics that adapt the forms of life to climatic conditions of various environments appear clear in the large dimensions of extremely differing climates. At the time of my arrival in Alaska many of the arctic Eskimos were still largely dependent on natural resources of their immediate and local environment, in which great seasonal changes in temperature and solar radiation appeared as dominant factors. The living environment on which they subsisted was also mar kedly affected by the changes of the seasons, in particular by the change in state of water to ice that terminated summer and by the melting that brought the late transition from winter to summer.

The definitive full-color field guide to Arctic wildlife The Arctic Guide presents the traveler and naturalist with a portable, authoritative guide to the flora and fauna of earth's northernmost region. Featuring superb color illustrations, this one-of-a-kind book covers the complete spectrum of wildlife—more than 800 species of plants, fishes, butterflies, birds, and mammals—that inhabit the Arctic’s polar deserts, tundra, taiga, sea ice, and oceans. It can be used anywhere in the entire Holarctic region, including Norway’s Svalbard archipelago, Siberia, the Russian Far East, islands of the Bering Sea, Alaska, the Canadian Arctic, and Greenland. Detailed species accounts describe key identification features, size, habitat, range, scientific name, and the unique characteristics that enable these organisms to survive in the extreme conditions of the Far North. A color distribution map accompanies each species account, and alternative names in German, French, Norwegian, Russian, Inuit, and Inupiaq are also provided. Features superb color plates that allow for quick identification of more than 800 species of plants, fishes, butterflies, birds, and mammals Includes detailed species accounts and color distribution maps Covers the flora and fauna of the entire Arctic region

Introduces animals that are built for living in the extreme cold of the polar regions, including the arctic fox, emperor penguins, snowy owls, and beluga whales.

This gorgeous coffee-table book is a celebration of Arctic wildlife, illustrated with many superb large-format colour photographs from an award-winning Canadian photographer. The authoritative textprovides an excellent overview of the arctic and its spectacular fauna and flora and the book is divided into chapters entitled Large and legendary, Arctic miniatures, Birds of the midnight sun, Hunters and the hunted, Polar mariners, and Waterwings. This is one of the most visually stunning books ever published on the subject.

A fascinating and complete insight into the group of animals to which we ourselves belong. David Attenborough introduces us to the most diverse group of animals ever to live on the Earth, from the smallest - the two-inch pygmy shrew, to the largest - the blue whale. The Life of Mammals is the story of 4,000 species which have outlived the dinosaurs and conquered the farthest places on earth.

With more than 200 gorgeous animal photos of penguins, polar bears, sea lions, walruses, reindeer and others, Animal Planet Polar Animals is a fun, habitat-by-habitat guide that provides kids in the first years of schooling with the perfect bite-sized view of their favorite animals living in both polar climates. Arranged thematically with focus on animal behavior and family relationships, young readers will explore sections about animal bodies, baby animals, food, play time, conservation, and more. Special book features designed for this age group include Quick Bites sidebars with cool animal facts, simple infographics, and illustrated maps of the coldest places on Earth.
