Book Description
Burrowing deep under the snow, collared lemmings use their shovel-like claws to create a secret world of tunnels hidden from predators. These small rodents put on their white winter coat each fall to blend in with their snowy home. Early readers will love digging through the pages of this fun, fact-filled read about the adaptations of collared lemmings.

Book Description
This book is a practical, portable guide to all of the Arctic's natural history—sky, atmosphere, terrain, ice, the sea, plants, birds, mammals, fish, and insects—for those who will experience the Arctic firsthand and for armchair travelers who would just as soon read about its splendors and surprises. It is packed with answers to naturalists' questions and with questions—some of them answered—that naturalists may not even have thought of.

Book Description
The best field guide to North American mammals The best-selling field guide that "sets new standards" (New Scientist) and "makes all other field guides for mammals of the United States. . . and Canada obsolete" (Journal of Mammalogy) is now even better. Covering 20 species recognized since 2002 and including 13 new color plates, this fully revised edition of Mammals of North America illustrates all 462 known mammal species in the United States and Canada—each in beautiful color and accurate detail. With a more up-to-date species list than any other guide, improved facing-page descriptions, easier-to-read distribution maps, updated common and scientific names, and track and scat illustrations, this slim, light, and easy-to-use volume is the must-have source for identifying North American mammals. Roland Kays and Don Wilson have scoured the technical literature to pull out the key differences between similar species, and illustrated these whenever possible, making the guide useful to amateur naturalists and professional zoologists alike. Casual animal watchers will appreciate the overview of mammal diversity and the tips on identifying animals they can spy in their binoculars, while scientists will appreciate the exacting detail needed to distinguish similar species, including illustrations of shrew teeth, bat toes, and whale dorsal fins. The best-illustrated and easiest-to-use field guide to North American mammals Beautiful and accurate color illustrations of all 462 mammals found in the United States and Canada—including 20 species recognized since 2002 112 color plates—including 13 new ones Key identification information—fully revised—on facing pages The most current taxonomy/species list Fully revised, easy-to-read range maps Illustrations of tracks, scat, and whale and dolphin dive sequences

Book Description
High-Arctic Ecosystem Dynamics in a Changing Climate is based on data collected during the past 10 years by Zackenberg Ecological Research Operations (ZERO) at Zackenberg Research Station in Northeast Greenland. This volume covers the function of Arctic ecosystems based on the most comprehensive long-term data set in the world from a well-defined Arctic ecosystem. Editors offer a comprehensive and authoritative analysis of how climate variability is influencing an Arctic ecosystem and how the Arctic ecosystems have inherent feedback mechanisms interacting with climate variability or change. - The latest research on the functioning of Arctic ecosystems - Supplements current books on arctic climate impact assessment as a case study for ecological specialists - Discusses the complex perpetuating effects on Earth - Vital information on modeling ecosystem responses to understand future climates

Book Description
North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.

Book Description
In most animals, from bees to bison, house flies to humans, it is possible to see at a glance whether an individual is male or female. How and why have these differences in appearance and behaviour developed and what are the nature and extent of the differences between men and women? This book reviews the latest molecular, genetic, hormonal, anatomical and behavioural data in a wide range of species in a series of lively and highly readable articles from the world's leading experts in this field. Such an overview has never before been attempted. It will have a wide appeal, especially to undergraduates and graduates in the biological and medical sciences, and will help to bridge the gap between those who study genes and molecules in the laboratory and those who study the behaviour of animals in the wild.

Book Description
The author spent four months in Baffin Island during 1953 as zoologist on a big expedition by the Arctic Institute of North America, where he concentrated on studying birds and mammals. With Inuit hunter Samo he travelled by dog-sledge on the sea-ice of coast and fjord. Afterwards he crossed the mountains alone in deep snow to reach the site of his summer camp in a valley among some of the most spectacular peaks in the world. There he worked for most of the summer, usually alone. The valley and others nearby were and still are uninhabited, and expedition members trod many places which had not been under human foot in recent centuries. His book is of special interest because of the many changes since, with the Inuit now mostly in towns with modern facilities and airports, and using motor sledges for hunting. The author writes of many exciting days studying arctic animals, sometimes working with Swiss botanist Fritz Schwarzenbach and others, and walking with heavy loads, sometimes in risky conditions. The beauty of the Arctic inspired and energised him. He writes vividly about the magnificent landscape, the 24-hour daylight, the endless variety of weather, snow and ice, the wonderful plants and animals in the brief summer of the far north.
