Originally published in 2001, Snow Ecology was the first book to integrate the study of snow and ice in the physical, chemical and biological sciences into a multidisciplinary overview of life in, on and under snow. The book opens up a perspective on snow cover as a habitat for organisms under extreme environmental conditions and as a key factor in the ecology of much of the earth's surface. Acknowledged experts in the disciplines that constitute snow science provide an understanding of the interrelationships between snow structure and life. It will form a useful textbook for advanced courses in biology, ecology, geography, environmental science and earth science where an important component is devoted to the study of the cryosphere. It will also be useful as a reference text for graduate students, researchers and professionals at academic institutions and in government and non-governmental agencies with environmental concerns.
