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.

    It condenses a huge amount of information about tree identification--more than has ever been collected in a single book--into a logical, accessible, easy-to-use format.With more than 4,100 meticulous, exquisitely detailed paintings, the Guide highlights the often subtle similarities and distinctions between more than 600 tree species--native trees as well as many introduced species. No other guide has ever made field identification so clear.Features highlighted include: - leaves (including multiple leaf shapes and fall leaf color)- bark- needles- cones- flowers- fruit- twigs- silhouettesMore than 500 maps show the complete range, both natural and cultivated, for nearly all species.Trees are arranged taxonomically, with all related species grouped together. By focusing on the fundamental characteristics of, for example, oaks or chestnuts or hickories, the Guide helps the user recognize these basic species groups the same way birders recognize thrushes, warblers, or sparrows.In addition, there are essays on taxonomy, on the cultivation of trees, and on conservation issues, reflecting Sibley's deep concern with habitat preservation and environmental health.An important new contribution to our understanding of the natural world, The Sibley Guide to Trees will be a necessity for every tree lover, traveler, and naturalist. It is sure to become the new benchmark in field guides to trees.

    Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed--a toxic plant named for the sticky white substance emitted when its leaves are damaged--and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed--the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers.Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

    In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    Indeed, Flora Britannica is the definitive contemporary flora, an encyclopaedia of living folklore, a register – a sort of Domesday Book.It is unique in that it is not a botanical flora but a cultural one – an account of the role of wild plants in social life, arts, custom and landscape. It is also unique in that information has been supplied by the people themselves. Five years of intensive original research have aroused popular interest and ‘grassroots’ involvement on an exceptional scale. People all over Britain – both rural and urban – have been encouraged to record and celebrate the cultural dimensions of their own flora, and to send their memories and anecdotes, observations and regional knowledge to Flora Britannica.The result is a nationwide record of the popular culture, domestic uses and social meanings of our wild plants. It is both useful and delightful – superbly written by one of the most outstanding English authors on natural history and illustrated with nearly 500 photographs. Including trees and ferns, it covers 1,000 species, many of them in considerable detail. A new flora for the people, Flora Britannica is a testimony to the continuing relationship between nature and human beings, and a celebration that the seasons and the landscape, local character and identity, still matter in Britain.
