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...

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...

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...

Ask anybody what superpower they wished to possess and odds are the answer just might be "the ability to fly." What is it about soaring through the air held up by the power of one's own body that has captivated humans for so long? David Alexander examines the evolution of flight in the only four animals to have evolved this ability: insects, pterosaurs, birds, and bats. With an accessible writing style grounded in rigorous research, Alexander breaks new ground in a field that has previousl...

How is it that we came to be here? The search for answers to that question has preoccupied humans for millennia. Scientists have sought clues in the genes of living things, in the physical environments of Earth from mountaintops to the depths of the ocean, in the chemistry of this world and those nearby, in the tiniest particles of matter, and in the deepest reaches of space. In Islands of the Cosmos, Dale A. Russell traces a path from the dawn of the universe to speculations about our fut...

The Arctic Tundra and adjacent Boreal Forest or Taiga support the most cold-adapted flora and fauna on Earth. The evolutionary capacity of both plants and animals to adapt to these thermally limiting conditions has always attracted biological investigation and is a central theme of this book. How the polar biota will adapt to a warmer world is creating significant and renewed interest in this habitat. The Arctic has always been subject to climatic fluctuation and the polar biota has succes...
