    In this beautiful new one-volume edition, modern readers are introduced to one of the best nature writers of the last century. More than one hundred of the original illustrations by Paul Landacre highlight the eloquent and entertaining accounts of American trees. As we read Peattie's descriptions, we catch glimpses of our country's history and past daily life that no textbook could ever illuminate so vividly.Here you'll learn about everything from how a species was discovered to the part it played in our country’s history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England's white pines, which made the best tall masts for fighting ships. It's fascinating to learn about the commercial uses of various woods -- for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon's portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed. A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man's nature, he reports sorrowfully on the greed and waste that have doomed so much of America's virgin forest.

    In this extraordinary feat of nature writing, we meet ants who harvest crops, raise insects as livestock, build roadways and bridges, embark on nuptial flights, and make war.

    But was it a savage sheep killer or a shy, fussy, nocturnal feeder? And did it really drink its victims' blood? Once reviled, feared and slaughtered by government decree, the myth of the Tasmanian Tiger continues to grow. So treasured is it now, the Tasmanian Tiger has become the official logo of the island that wiped it out and a symbol of the conservation movement world-wide.A number of Australian species have miraculously reappeared after being labelled as extinct. Perhaps the Tiger is still with us. And if it's not, can it be brought back by cloning?

    Turner's clear, insightful prose and Anton's masterly illustrations combine to offer specialists and newcomers alike an accurate and accessible guide to the evolution of cats.

    Chapters on the structure and ecology of tree bark, descriptions of bark appearance, an easy-to-use identification key, and supplemental information on non-bark characteristics—all enhanced by over 450 photographs, illustrations, and maps—will show you how to distinguish the textures, shapes, and colors of bark to recognize various tree species, and also understand why these traits evolved. Whether you’re a professional naturalist or a parent leading a family hike, Bark: A Field Guide to Trees of the Northeast is your essential guide to the region’s 67 native and naturalized tree species.

    It is a hands-on guide to learning about the natural environment of California. Subjects covered include California natural history and geology, native plants and animals, California's freshwater resources and ecosystems, forest and rangeland resources, conservation biology, and the effects of global warming on California's natural communities. The Handbook also discusses how to create and use a field notebook, natural resource interpretation, citizen science, and collaborative conservation and serves as the primary text for the California Naturalist Program.

    Now, with an astonishing new discovery, everything we thought we knew about primate origins could change. Lying inside a high-security vault, deep within the heart of one of the world's leading natural history museums, is the scientific find of a lifetime - a perfectly fossilized early primate, older than the previously most famous primate fossil, Lucy, by forty-four million years.  A secret until now, the fossil - "Ida" to the researchers who have painstakingly verified her provenance - is the most complete primate fossil ever found. Forty-seven million years old, Ida rewrites what we've assumed about the earliest primate origins. Her completeness is unparalleled - so much of what we understand about evolution comes from partial fossils and even single bones, but Ida's fossilization offers much more than that, from a haunting "skin shadow" to her stomach contents. And, remarkably, knowledge of her discovery and existence almost never saw the light of day. With exclusive access to the first scientists to study her, the award-winning science writer Colin Tudge tells the history of Ida and her place in the world. A magnificent, cutting-edge scientific detective story followed her discovery, and The Link offers a wide-ranging investigation into Ida and our earliest origins. At the same time, it opens a stunningly evocative window into our past and changes what we know about primate evolution and, ultimately, our own.

    The author explodes the old orthodoxies and gives us a convincing picture of how dinosaurs hunted, fed, mated, fought and died.Containing over 200 detailed illustrations, The Great Dinosaur Debate will enthrall "dinosaurmaniacs". It is a bold new look at the extraordinary reign and eventual extinction of the awesome behemoths who ruled the earth for 150 million years.

    With whimsically hip illustrations, every page is an extraordinary look at all kinds of subjects, from mineral formation and the inside of a volcano to what makes sunsets, monarch butterfly migration, the ecosystem of a rotting log, the parts of a bird, the anatomy of a jellyfish, and much, much more.

    Line drawings highlight family characteristics, and plant entries discuss medicinal uses, edibility, toxicity, and look-alike plants. A standard reference at herbal and wilderness schools across the country, this resource is essential for herbalists, gardeners, and naturalists.
