Cryosols occupy a unique part of the earth and have properties greatly different from other soils. They also occur where the greatest impact of global warming is predicted. They have been studied extensively in Russia, Canada and in other regions. This is, however, the first book which brings together experts from all fields in order to focus on these unique soils. It will undoubtedly provide one of the best sources of information available about these soils.

By looking backward at the course of great extinctions, a paleontologist sees what the future holds.More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90 percent of all species and nearly 97 percent of all living things. Its origins have long been a puzzle for paleontologists. During the 1990s and the early part of this century, a great battle was fought between those who thought that death had come from above and those who thou...

"Michael Benton's splendid book brings back to Earth Science a sense of adventure. . . . It is both a wonderfully good read and a valued reference." —James Lovelock, author of Gaia and Homage to GaiaToday it is common knowledge that the dinosaurs were wiped out by a meteorite impact 65 million years ago that killed half of all species then living. Far less well-known is a much greater catastrophe that took place at the end of the Permian period 251 million years a...

Earth's past is littered with the mysterious and unexplained: the pyramids, Easter Island, Stonehenge, dinosaurs, and the list goes on and on as science looks for clues to decipher these puzzles.One such mystery surrounds the now-extinct creature called the woolly mammoth. Author and meteorologist Michael Oard has studied the mammoth and its equally mysterious time period, the Ice Age, for many years and has come to some fascinating conclusions to help lift the fog engulfing the fac...

"[A] scholarly but accessible analysis . . . [explores] forces that led to 'The Great Dying'—and the rebound of life in its aftermath." — Gemma Tarlach, Discover magazineTwo hundred sixty million years ago, life on Earth suffered wave after wave of cataclysmic extinctions, with the worst wiping out nearly every species on the planet. The Worst of Times delves into the mystery behind these extin...

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biolog...

Freshwater Ecology: Concepts and Environmental Applications is a general text covering both basic and applied aspects of freshwater ecology and serves as an introduction to the study of lakes and streams. Issues of spatial and temporal scale, anthropogenic impacts, and application of current ecological concepts are covered along with ideas that are presented in more traditional limnological texts. Chapters on biodiversity, toxic chemicals, extreme and unusual habitats, and fisheries increa...

This text is designed for students and anyone else with an interest in the history of life on our planet. The author describes the biological evolution of Earth’s organisms, and reconstructs their adaptations to the life they led, and the ecology and environment in which they functioned. On the grand scale, Earth is a constantly changing planet, continually presenting organisms with challenges. Changing geography, climate, atmosphere, oceanic and land environments set a stage in which orga...

This new edition of an established textbook provides a comprehensive and stimulating introduction to rivers, lakes and wetlands, and was written as the basis for a complete course on freshwater ecology. Designed for undergraduate and early postgraduate students who wish to gain an overall view of this vast subject area, this accessible guide to freshwater ecosystems and man's activities will also be invaluable to anyone interested in the integrated management of freshwaters. The author mai...

The invasion of land by ocean-dwelling plants and animals was one of the most revolutionary events in the evolution of life on Earth, yet the animal invasion almost failed—twice—because of the twin mass extinctions of the Late Devonian Epoch. Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects—instead of vertebrates—might have become the ec...

Humanity’s ever-increasing hunger for mineral raw materials, caused by a growing global population and ever increasing standards of living, has resulted in economic geology becoming a subject of urgent importance.This book provides a broad panorama of mineral deposits, covering their origin and geological characteristics, the principles of the search for ores and minerals, and the investigation of newly found deposits. Practical and environmental issues that arise during the life c...

In its first edition, Soils established itself as the leading textbook in the fields of pedology and soil geomorphology. Expanded and fully updated, this second edition maintains its highly organized and readable style. Suitable as a textbook and a research-grade reference, the book's introductory chapters in soil morphology, mineralogy, chemistry, physics and organisms prepare the reader for the more advanced treatment that follows. Unlike its competitors, this textbook devotes considerab...
