Based on the acclaimed reference Lichens of North America, this resource for the classroom, field, and laboratory presents updated and expanded keys for the identification of over 2,000 species of lichens indigenous to the continent, twice the number covered by previous keys. The book includes a glossary illustrated with photographs by Sylvia Duran Sharnoff and Stephen Sharnoff and drawings by Susan Laurie-Bourque, all from the original book. The revised keys are an indispensable identification tool for botanists, students, scientists, and enthusiasts alike.--COVER.
Lichens are a unique form of plant life, the product of a symbiotic association between an alga and a fungus. The beauty and importance of lichens have long been overlooked, despite their abundance and diversity in most parts of North America and elsewhere in the world. This stunning book--the first accessible and authoritative guidebook to lichens of the North American continent--fills the gap, presenting superb color photographs, descriptions, distribution maps, and keys for identifying the most common, conspicuous, or ecologically significant species. The book focuses on 805 foliose, fruticose, and crustose lichens (the latter rarely included in popular guidebooks) and presents informatio...
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 future on this planet. He centers his story on the physical and biological processes in evolution, which interact to favor more successful, and eliminate less successful, forms of life. Marvelously, these processes reveal latent possibilities in life's basic structure, and propel a major evolutionary theme: the increasing proficiency of biological function. It remains to be seen whether the human form can survive the dynamic processes that brought it into existence. Yet the emergence of the ability to acquire knowledge from experience, to optimize behavior, to conceptualize, to distinguish "good" from "bad" behavior all hint at an evolutionary outcome that science is only beginning to understand.
An integrated picture of prehistory as an active process of discovery. World Prehistory and Archaeology: Pathways through Time, third edition, provides an integrated discussion of world prehistory and archaeological methods. This text emphasizes the relevance of how we know and what we know about our human prehistory. A cornerstone of World Prehistory and Archaeology is the discussion of prehistory as an active process of discovery. Methodological issues are addressed throughout the text to engage readers. Archaeological methods are introduced in the first two chapters. Succeeding chapters then address the question of how we know the past to provide an integrated presentation of prehistory. ...
