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.

    Over 380 genera. More than 3700 species and cultivars.Dirr's Encyclopedia of Trees and Shrubs is the most comprehensive visual reference to more than 3700 species and cultivars.

    Yet discoveries over the past fifty years have challenged these ideas, shedding new light on the extraordinary capabilities and complex interior lives of plants. In Brilliant Green, Stefano Mancuso, a leading scientist and founder of the field of plant neurobiology, presents a new paradigm in our understanding of the vegetal world. Combining a historical perspective with the latest in plant science, Mancuso argues that, due to cultural prejudices and human arrogance, we continue to underestimate plants. In fact, they process information, sleep, remember, and signal to one another -- showing that, far from passive machines, plants are intelligent and aware. Through a survey of plant capabilities from sight and touch to communication, Mancuso challenges our notion of intelligence, presenting a vision of plant life that is more sophisticated than most imagine. Plants have much to teach us, from network building to innovations in robotics and man-made materials -- but only if we understand more about how they live. Part botany lesson, part manifesto, Brilliant Green is an engaging and passionate examination of the inner workings of the plant kingdom. Financial support for the translation of this book has been provided by SEPS: Segretariato Europeo Per Le Pubblicazioni Scientifiche.

    In Tree: A Life Story, authors David Suzuki and Wayne Grady extend that celebration in a "biography" of this extraordinary—and extraordinarily important—organism. A story that spans a millennium and includes a cast of millions but focuses on a single tree, a Douglas fir, Tree describes in poetic detail the organism's modest origins that begin with a dramatic burst of millions of microscopic grains of pollen. The authors recount the amazing characteristics of the species, how they reproduce and how they receive from and offer nourishment to generations of other plants and animals. The tree's pivotal role in making life possible for the creatures around it—including human beings—is lovingly explored. The richly detailed text and Robert Bateman's original art pay tribute to this ubiquitous organism that is too often taken for granted. Also available in hardcover.Published in partnership with the David Suzuki Foundation.

    The renowned biologist Daniel Chamovitz builds on the original edition to present an intriguing look at how plants themselves experience the world—from the colors they see to the schedules they keep, and now, what they do in fact hear and how they are able to taste. A rare inside look at what life is really like for the grass we walk on, the flowers we sniff, and the trees we climb, What a Plant Knows offers a greater understanding of their place in nature.

    There they began a strenuous and thrilling hundred-day field trip around the edge of the continent. Part travelogue, part epic natural adventure, their richly illustrated record is "the superlatively good product of ideal circumstances" (Chicago Sunday Tribune).

    The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.

    In an upbeat and original way of thinking Quammen writes about beetles, bats, crows, snakes and other interesting animals.

    Yet when it comes to fungi, culinary uses are only the tip of the iceberg. Throughout history fungus has been prized for its diverse properties—medicinal, ecological, even recreational—and hasspawned its own quirky subculture dedicated to exploring the weird biology and celebrating the unique role it plays on earth. In Mycophilia, accomplished food writer and cookbook author Eugenia Bone examines the role of fungi as exotic delicacy, curative, poison, and hallucinogen, and ultimately discovers that a greater understanding of fungi is key to facing many challenges of the 21st century.Engrossing, surprising, and packed with up-to-date science and cultural exploration, Mycophilia is part narrative and part primer for foodies, science buffs, environmental advocates, and anyone interested in learning a lot about one of the least understood and most curious organisms in nature.
