This account of the life of the tundra provides a fascinating insight into the ways in which animals, plants and climate interact in an inhospitable environment.

Explores the biodiversity of forests, from microbes to mammals, as well as the adaptations of organisms to their environment and to the other species surrounding them. This book examines the interactions between organisms and their physical surroundings and the processes that link the two into an integrated ecosystem.

Written by more than 70 scientists from around the world, this publication assesses the state of the environment and the trends in ice and snow-covered regions (the cryosphere). It looks at the significance of climate changes for ecosystems and human well-being, both now and in the years to come, given that changes in ice and snow alter the distribution of the earth's heat and water, and influence regional and global ocean circulation. This publication is an official project of the International Polar Year 2007-2008.

Dynamics of Ice Sheets and Glaciers presents an introduction to the dynamics and thermodynamics of flowing ice masses on Earth. Based on an outline of general continuum mechanics, the different initial-boundary-value problems for the flow of ice sheets, ice shelves, ice caps and glaciers are systematically derived. Special emphasis is put on developing hierarchies of approximations for the different systems, and suitable numerical solution techniques are discussed. A separate chapter is devoted to glacial isostasy. The book is appropriate for graduate courses in glaciology, cryospheric sciences, environmental sciences, geophysics and related fields. Standard undergraduate knowledge of mathematics (calculus, linear algebra) and physics (classical mechanics, thermodynamics) provide a sufficient background for successfully studying the text.

This book is the most comprehensive empirical study to date of the social and technical aspects of milling during the ancient and medieval periods.Drawing on the latest archaeological evidence and historical studies, the book examines the chronological development and technical details of handmills, beast mills, watermills and windmills from the first millennium BCE to c. 1500. It discusses the many and varied uses to which mills were turned in the civilisations of Rome, China, Islam and Europe, and the many types of mill that existed.The book also includes comparative regional studies of the social and economic significance of milling, and tackles several important historiographical issues, such as whether technological stagnation was a characteristic of late Antiquity, whether there was an industrial revolution" in the European Middle Ages based on waterpower, and how contemporary studies in the social shaping of technology can shed light on the study of pre-modern technology."

This title will introduce readers to tundra ecosystems, the plants and animals that thrive there, its climate, its food web, any threats to it, and conservation efforts. Readers will also learn about the most well known tundras and their unique characteristics. . Aligned to Common Core Standards and correlated to state standards.
