"The genius of Hanson's fascinating, inspiring, and entertaining book stems from the fact that it is not about how all kinds of things grow from seeds; it is about the seeds themselves." -- Mark Kurlansky, New York Times Book Review We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life: supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and pepper drove the Age of Discovery, coffee beans fueled the Enlightenment and cottonseed sparked the Industrial Revolution. Seeds are fundamental objects of beauty, evolutionary wonders, and simple fascinations. Yet, despite their importance, seeds are often seen as commonplace, their extraordinary natural and human histories overlooked. Thanks to this stunning new book, they can be overlooked no more. This is a book of knowledge, adventure, and wonder, spun by an award-winning writer with both the charm of a fireside story-teller and the hard-won expertise of a field biologist. A fascinating scientific adventure, it is essential reading for anyone who loves to see a plant grow.

    Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.

    This clear, concise look at the basic principles and concepts of genetics uses a human genetics perspective to discuss the methods and experiments upon which genetic principles are based, such as DNA replication.

    In transcribing the 150-year-old manuscript’s cryptic handwriting and complex notations, Thoreau specialist Bradley Dean has performed a "heroic feat of decipherment" (Booklist) to bring this great work to light. Readers will discover "passages that reach for the transcendentalist ideal of writing new scriptures, yet grounding this Bible in a vision of practical ecology" (Boston). Beautifully illustrated throughout with line drawings of the natural life Thoreau considers on his walks, Wild Fruits is "well worth any nature lover’s attention" (Christian Science Monitor).

    How did they come to be the villains of the natural world? And why can the same plant be considered beautiful in some places but be deemed a menace in others?In Weeds, renowned nature writer Richard Mabey embarks on an engaging journey with the verve and historical breadth of Michael Pollan. Weaving together the insights of botanists, gardeners, artists, and writers with his own travels and lifelong fascination, Mabey shows how these "botanical thugs" can destroy ecosystems but also can restore war zones and derelict cities; he reveals how weeds have been portrayed, from the "thorns and thistles" of Genesis to Shakespeare, Walden, and Invasion of the Body Snatchers; and he explains how kudzu overtook the American South, how poppies sprang up in First World War battlefields, and how "American weed" replaced the forests of Vietnam ravaged by Agent Orange.Hailed as "a profound and sympathetic meditation on weeds in relation to human beings" (Sunday Times), Weeds shows how useful these unloved plants can be, from serving as the first crops and medicines, to bur-dock inspiring the invention of Velcro, to cow parsley becoming the latest fashionable wedding adornment. Mabey argues that we have caused plants to become weeds through our reckless treatment of the earth, and he delivers a provocative defense of the plants we love to hate.

    It was to last five years and transform him from an amiable and somewhat aimless young man into a scientific celebrity. Even more vitally, it was to set in motion the intellectual currents that culminated in the arrival of The Origin of Species in Victorian drawing-rooms in 1859. His journal, reprinted here in a shortened version, is vivid and immediate, showing us a naturalist making patient observations, above all in geology. As well as a profusion of natural history detail, it records many other things that caught Darwin’s eye, from civil war in Argentina to the new colonial settlements of Australia. The editors have provided an excellent introduction and notes for this Penguin Classics edition, which also contains maps and appendices, including an essay on scientific geology and the Bible by Robert FitzRoy, Darwin’s friend and captain of the Beagle.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    Thus, the literature on speciation, as well as the number of researchers and students working in this area, has grown explosively. Despite thesedevelopments, there has been no book-length treatment of speciation in many years. As a result, both the seasoned scholar and the newcomer to evolutionary biology had no ready guide to the recent literature on speciation--a body of work that is enormous, scattered, and increasingly technical.Although several excellent symposium volumes have recently appeared, these collections do not provide a unified, critical, and up-to-date overview of the field. Speciation is designed to fill this gap.Aimed at professional biologists, graduate students, and advanced undergraduates, Speciation covers both plants and animals (the first book on this subject to do so), and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecularstudies. It gives special emphasis to topics that are either controversial or the subject of active research, including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural andsexual selection in the origin of species. The authors do not hesitate to take stands on these and other controversial issues. This critical and scholarly book will be invaluable to researchers in evolutionary biology and is also ideal for a graduate-level course on speciation.

    Most conservationists and environmentalists share this view. But what if the traditional view of ecology is wrong—what if true environmentalists should be applauding the invaders? In The New Wild, Pearce goes on a journey across six continents to rediscover what conservation in the twenty-first century should be about. Pearce explores ecosystems from remote Pacific islands to the United Kingdom, from San Francisco Bay to the Great Lakes, as he digs into questionable estimates of the cost of invader species and reveals the outdated intellectual sources of our ideas about the balance of nature. Pearce acknowledges that there are horror stories about alien species disrupting ecosystems, but most of the time, the tens of thousands of introduced species usually swiftly die out or settle down and become model eco-citizens. The case for keeping out alien species, he finds, looks increasingly flawed. As Pearce argues, mainstream environmentalists are right that we need a rewilding of the earth, but they are wrong if they imagine that we can achieve that by reengineering ecosystems. Humans have changed the planet too much, and nature never goes backward. But a growing group of scientists is taking a fresh look at how species interact in the wild. According to these new ecologists, we should applaud the dynamism of alien species and the novel ecosystems they create. In an era of climate change and widespread ecological damage, it is absolutely crucial that we find ways to help nature regenerate. Embracing the new ecology, Pearce shows us, is our best chance. To be an environmentalist in the twenty-first century means celebrating nature’s wildness and capacity for change.

    Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group.Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth.

    Wherever you are right now, the chances are that there are worms, woodlice, centipedes, flies, silverfish, wasps, beetles, mice, shrews and much, much more, quietly living within just a few paces of you.Dave Goulson gives us an insight into the fascinating and sometimes weird lives of these creatures, taking us burrowing into the compost heap, digging under the lawn and diving into the garden pond. He explains how our lives and ultimately the fate of humankind are inextricably intertwined with that of earwigs, bees, lacewings and hoverflies, unappreciated heroes of the natural world.The Garden Jungle is at times an immensely serious book, exploring the environmental harm inadvertently done by gardeners who buy intensively reared plants in disposable plastic pots, sprayed with pesticides and grown in peat cut from the ground. Goulson argues that gardens could become places where we can reconnect with nature and rediscover where food comes from. With just a few small changes, our gardens could become a vast network of tiny nature reserves, where humans and wildlife can thrive together in harmony rather than conflict.For anyone who has a garden, and cares about our planet, this book is essential reading.

    Wherever there is greenery, photosynthesis isworking to make oxygen, release energy, and create living matter from the raw material of sunlight, water, and carbon dioxide. Without photosynthesis, there would be an empty world, an empty sky, and a sun that does nothing more than warm the rocks and reflect off the sea. With photosynthesis, we have a living world with three billion years of sunlight-fed history to relish.Eating the Sun is a bottom-up account of our planet, a celebration of how the smallest things, enzymes and pigments, influence the largest things­­—the oceans, the rainforests, and the fossil fuel economy. From the physics, chemistry, and cellular biology that make photosynthesis possible, to the quirky and competitive scientists who first discovered the beautifully honed mechanisms of photosynthesis, to the modern energy crisis we face today, Oliver Morton offers a complete biography of the earth through the lens of this mundane and most important of processes.More than this, Eating the Sun is a call to arms. Only by understanding photosynthesis and the flows of energy it causes can we hope to understand the depth and subtlety of the current crisis in the planet's climate. What's more, nature's greatest energy technology may yet inspire the breakthroughs we need to flourish without such climatic chaos in the century to come.Entertaining, thought-provoking, and deeply illuminating, Eating the Sun reveals that photosynthesis is not only the key to humanity's history; it is also vital to confronting and understanding contemporary realities like climate change and the global food shortage. This book will give you a new and perhaps troubling way of seeing the world, but it also explains how we can change our situation—for the better or the worse.
