The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

    It is the most complete photographic guide to British birds ever published and the only one to be designed to give everything that you need on each spread in a simple-to-use format. Every text entry covers identification of adults and juveniles, songs and calls, and where they are most likely to be found.Illustrated with specially commissioned photography and maps to show where in Britain the birds are found and at what time of year, this accessible guide also features cross-references to similar-looking species, containing everything a birdwatcher needs to know in one, easy-to-use, portable volume. It is the perfect photographic field guide for the birdwatching beginner.

    A collection of fascinating facts, tidbits and quotes from the world of science and technology.This is a quick read, which you can easily scan through and find easy to read, short facts about the world around us, as well as some quotes from well known faces in science.Topics in the book include;BiologyChemistryPhysicsHealthSocietyEarth & EnvironmentAnimals & NatureSpaceTechnology & EngineeringQuotes

    The introduction contains illustrations of the main leaves, buds, and firs you are likely to find, and these provide the starting point for identification by leading you to a 'key' species.Within each tree family there is a list of key species and a guide to the most important features to look for when identifying a particular tree from that family. Then individual species are clearly described and a detailed illustration is given on the same page.Covering all the tree species found outside the major arboretums, from the olive tree to the eucalyptus, this is one of the most important tree guides to have appeared in the last 20 years. The illustrations are annotated with essential identification features, and the text highlights the most important things to look for to aid fast and accurate identification. There is also coverage of all the species native to Southern Europe.

    Nearly 700 species of trees are detailed in photographs of leaf shape, bark, flowers, fruit, and fall leaves -- all can be quickly accessed making this the ideal field guide for any time of year. Note: the Eastern Edition generally covers states east of the Rocky Mountains, while the Western Edition covers the Rocky Mountain range and all the states to the west of it.

    

    Now comes a new portable guide from David Sibley that every birder will want to carry into the field. Compact and comprehensive, this new guide features 703 bird species plus regional populations found west of the Rocky Mountains. Accounts include stunningly accurate illustrations—more than 4,600 in total—with descriptive caption text pointing out the most important field marks. Each entry contains new text concerning frequency, nesting, behavior, food and feeding, voice description, and key identification features. Accounts also include brand-new maps created from information contributed by 110 regional experts across the continent. The Sibley Field Guide to Birds of Western North America is an indispensable resource for all birders seeking an authoritative and portable guide to the birds of the West.

    The most comprehensive field guide available to the flora and fauna of California--a portable, essential companion for visitors and residents alike--from the go-to reference source for over 18 million nature lovers.This compact volume contains:An easy-to-use field guide for identifying 1,000 of the state's wildflowers, trees, mushrooms, mosses, fishes, amphibians, reptiles, birds, butterflies, mammals, and much more;A complete overview of California's natural history, covering geology, wildlife habitats, ecology, fossils, rocks and minerals, clouds and weather patterns and night sky;An extensive sampling of the area's best parks, preserves, beaches, forests, islands, and wildlife sanctuaries, with detailed descriptions and visitor information for 50 sites and notes on dozens of others.The guide is packed with visual information -- the 1,500 full-color images include more than 1,300 photographs, 14 maps, and 16 night-sky charts, as well as 150 drawings explaining everything from geological processes to the basic features of different plants and animals.

Easy-to-use facing-page format.

    More than 2,000 stunning images show these trees in their natural habitats. Other features include: a unique identification tip for each tree; range maps showing distribution in North America; How to Identify a Tree section; a detailed glossary of tree parts and leaf, fruit, flower, and bark types; essays on ecology, conservation, and North America’s important forest types; plus a complex species and quick-flip indexes. The guide’s unique waterproof cover makes it especially valuable for use in the field.

    This claim is not only false, but its presence in the debate is an insult to science." With these words, the authors begin a detailed analysis of one of the most controversial topics of the day. The authors make a compelling case against claims of a scientific consensus. The purported proof of such a consensus consists of sloppy research by nonscientists, college students, and a highly partisan Australian blogger. Surveys of climate scientists, even those heavily biased in favor of climate alarmism, find extensive disagreement on the underlying science and doubts about its reliability. The authors point to four reasons why scientists disagree about global warming: a conflict among scientists in different and often competing disciplines; fundamental scientific uncertainties concerning how the global climate responds to the human presence; failure of the United Nations Intergovernmental Panel on Climate Change (IPCC) to provide objective guidance to the complex science; and bias among researchers. The authors offer a succinct summary of the real science of climate change based on their previously published comprehensive review of climate science in a volume titled Climate Change Reconsidered II: Physical Science. They recommend that policymakers resist pressure from lobby groups to silence scientists who question the authority of the IPCC to claim to speak for climate science. More than 50,000 copies of the first edition were sold or given away in five months to elected officials, civic and business leaders, scientists, and other opinion leaders. The response from the science community and experts on climate change has been overwhelmingly positive. To meet demand for more copies, we have produced this second revised edition. Changes include a foreword by Marita Noon, at the time executive director of Energy Makes America Great, Inc. Some of the discussion in Chapter 1 has been revised and expanded thanks to feedback from readers of the first edition. Graphs in Chapters 4, 5, and 6 are now full color, and new graphs have been added.

    This is a clear, vivid text with charts and maps showing the positions of the constellations the year round.

    The 762 full-color identification photographs show the mushrooms as they appear in natural habitats. Organized visually, the book groups all mushrooms by color and shape to make identification simple and accurate in the field, while the text account for each species includes a detailed physical description, information on edibility, season, habitat, range, look-alikes, alternative names, and facts on edible and poisonous species, uses, and folklore. A supplementary section on cooking and eating wild mushrooms, and illustrations identifying the parts of a mushroom, round out this essential guide.

    Descriptive text includes measurements, diagnostic details, and information on habitat, range, feeding habits, sounds or songs, flight period, web construction, life cycle, behaviors, folklore, and environmental impact. An illustrated key to the insect orders and detailed drawings of the parts of insects, spiders, and butterflies supplement this extensive coverage.
