But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    Gravetter, and co-author Lori-Ann B. Forzano have written a text for research methods that helps you see how interesting and exciting experimental and non-experimental research can be. Inviting and conversational, RESEARCH METHODS FOR THE BEHAVIORAL SCIENCES, Third Edition, leads you through the research process from start to finish. The text opens with tips and strategies for generating research ideas, moves to selecting measures and participants, and then offers an examination of research strategy and design. This step-by-step approach emphasizes the decisions researchers must make at each stage of the process. The authors avoid a "cookbook" approach to the facts by linking terminology with applied concepts; their "lecture in a book" style emphasizes discussion and explanation of topics. Each chapter ends with a set of exercises and activities.

    College Edition, an online university library. At the core of this learning package is Ahrens' respected text, which presents the fundamental concepts of meteorology in the context of everyday weather observations. Fun and easy to understand and relate to, the book and its cumulative organization enables students to build on each concept and gain greater understanding into the dynamic nature of the atmosphere.

    The book covers habituation, classical conditioning, instrumental conditioning, stimulus control, aversive control, and their applications to the study of cognition and to the alleviation of behavior problems. Biological constraints on learning are integrated throughout the text, as are applications boxes that relate animal research to human learning and behavior. The book closely reflects the field of research it represents in terms of topics covered, theories discussed, and experimental paradigms described.

    The National Audubon Society Field Guide to the Night Sky provides a concise guided tour of the heavens, from planets in our solar system to the constellations in both the Northern and Southern hemispheres, stars, galaxies, astronomical bodies, phenomena, comets, and more. Featuring a durable vinyl binding, over 700 full-color photographs, sky charts, and constellation charts, as well as detailed descriptive text, this comprehensive, easy-to-use field guide is the perfect companion volume for any stargazer.

    

    

    He shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the sudden evolution of animals, the need for two sexes, the accelerated aging of cloned animals like Dolly the sheep, and the surprisingly long lives of bats and birds. Drawing on this grand evolutionary canvas, Oxygen offers fresh perspectives on our own lives and deaths, explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of our place in nature. This remarkable book will redefine the way we think about the world.

    Fully illustrated and comprehensive, each volume includes practical information, time-tested nature skills, and exciting new ways to rediscover the earth around us.

    Exceptional Coverage. This authoritative volume starts with a clear introduction to the animal world, examining the reasons for the apparently infinite variety of animal forms and major evolutionary developments. Animal anatomy, life cycles and the principles of classification are also explored. This is followed by a superbly illustrated survey of world habitats, showing how they have adapted to each environment, and the threats that face both wildlife and plants today. The main part of the book, an up-to-date and comprehensive animal catalog, looks in detail at each major group and provides fascinating profiles of over 2,000 individual species. Visually Breathtaking. Spectacular photographic portraits bring a vast array of animals vividly to life, with special features on well-known and important animals such as the Galapagos tortoise. Each species profile is supported by maps and symbols showing distribution and habitat, as well as key information on size, population, and conservation status, forming an invaluable reference database. Outstanding Reference. Clear, comprehensive, and thought provoking, the Smithsonian Animal is essential reading for wildlife enthusiasts of all ages and levels of experience.

    A color wildflower identification guide is included in the 20 pages of color photos. The back of the book includes brief descriptions of 109 more hikes.

    Now in its second edition, this climbing and hiking guide to Colorado's 14,000–foot peaks has been updated to include 250 routes. Besides the often–climbed standard routes, the guide describes many alternative and technical routes, with each route rated by grade, class, and snow steepness. Easy–to–read, full–color topographic maps and photographic overlays, cross–referenced to the route descriptions, make this the best book on the market for Colorado natives and visitors alike.1999 "Colorado Book Award" Finalist

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    Its pages contain 1,200 colour illustrations, plus seven comparison spreads, with comprehensive text on identification, habitats, food, breeding and conservation, and accurate range maps. In addition, the epub edition features songs, calls and other sounds from each species, making this the ultimate one-stop resources for anyone interested in identifying and learning more about the birds they see.This collection of images and sounds represents a step change in the way birdwatchers operate. No more carrying heavy books into the field; no more trying to remember sounds days later, while all other methods for taking sounds into the field are consigned to the dustbin.The RSPB Handbook of British Birds e-book provides a complete field-based ID solution – no birdwatcher will want to be without it.(Note: Audio may not play on all devices.
