Why does the chestnut-sided warbler sing one song before dawn and another after sunrise? Why does the brown thrasher have a repertoire of two thousand songs when the chipping sparrow has only one? And how is the hermit thrush able to sing a duet with itself, producing two sounds simultaneously to create its beautiful, flutelike melody?Stap's lucid prose distills the complexities of the study of birdsong and unveils a remarkable discovery that sheds light on the mystery of mysteries: why young birds in the suborder oscines -- the "true songbirds" -- learn their songs but the closely related suboscines are born with their songs genetically encoded. As the story unfolds, Stap contemplates our enduring fascination with birdsong, from ancient pictographs and early Greek soothsayers, who knew that bird calls represented the voices of the gods, to the story of Mozart's pet starling.In a modern, noisy world, it is increasingly difficult to hear those voices of the gods. Exploring birdsong takes us to that rare place -- in danger of disappearing forever -- where one hears only the planet's oldest music.

    With numerous black-and-white images and eight pages of color plates, The Lives of Ants provides a state-of-the-art look at what we now know about these fascinating creatures, portraying a world that is rich and full of surprises, one which, even after decades of observation, is still full of unsolved mysteries.The authors illuminate the world of the ant, shedding light on such topics as the ant's impressive abilities in direction finding and quite amazing ingenuity when it comes to building their nests, finding supplies, or exploiting other members of the animal kingdom. They show, too, that they are capable of aggression and violence, which can disturb the apparent peace of their colonies and embroil them in fratricidal or matricidal strife. Even their sexual arrangements are at times quite strange. In this area, as in many others, they display marked originality. Readers also discover that ants are walking bundles of secretory glands (they have about forty of them), which enable them to emit between ten and twenty different pheromones, each of which has its own "meaning." Some are produced by workers for recruiting their sisters or for alerting them to danger. Others are used for marking territory, for identifying members of their colony or conversely for detecting foreigners, and for indicating the location of food. In addition, ants can also emit sound signals, made of a high-pitched squeak, and they can even dance, though not as intricately or as well as bees.The Lives of Ants combines natural history with molecular biology, genetics, and even the latest developments in robotics, to explore the remarkable societies of ants, revealing the secrets of their mysterious lives.

    What explains these far-flung distributions? Why are species found where they are across the Earth? Since the discovery of plate tectonics, scientists have long conjectured that plants and animals were scattered over the globe by riding pieces of ancient supercontinents as they broke up. In the past decade, however, that theory has foundered, as the genomic revolution has made reams of new genetic data available. And the data has revealed an extraordinary, stranger-than-fiction story that has sparked a scientific revolution. In The Monkey's Voyage, biologist Alan de Queiroz introduces a radical new theory of how species as diverse as monkeys, baobab trees, and burrowing lizards made incredible long-distance ocean crossings: pregnant animals and wind-blown plants rode rafts and icebergs and even stowed away on the legs of sea-going birds to create the map of life we see today. In other words, these organisms were not merely victims of continental fate; they were masters of their geographic destiny. And as de Queiroz shows, the effects of oceanic dispersal have been crucial in generating the diversity of life on Earth, from monkeys and guinea pigs in South America to beech trees and kiwi birds in New Zealand. By toppling the idea that the slow process of continental drift drove odd distributions of organisms, this new theory highlights the dynamic and unpredictable nature of the history of life. In the tradition of John McPhee’s Basin and Range, The Monkey's Voyage is a beautifully told narrative of a profound investigation into the importance of contingency in history and the nature of scientific discovery.

    Only seven of these are responsible for creating the world's sweetest treat—honey. Combining Ilona's gorgeous photography and E. Readicker-Henderson's engaging text, A Short History of the Honey Bee follows the journey from flower to hive to honey throughout history.A Short History of the Honey Bee starts with the story of the honey bee—why it is named Apis mellifera, how it has evolved from a solitary creature to one that travels in groups, why it stings, and how pollination really works. Readicker-Henderson then moves on to the honey, detailing its history from a wild food foraged for on cliffs to the many varieties available for purchase today. But it is the everyday importance of the bee that remains the central message. Forty percent of the world's food supply—including apples, tomatoes, and strawberries—is dependent on pollination by honeybees. Colony collapse, when the worker bees suddenly disappear and leave behind the queen and the hive, is an ecological and agricultural crisis. For this reason alone we need to be more aware of the significance of bees.

    Stringer's new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies.Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved.Lone Survivors will be the definitive account of who and what we were, and will change perceptions about our origins and about what it means to be human.

    Yet we take supplies of clean water and secure food for granted, rarely considering the free work nature does for Britain. In fact for years we have damaged the systems that sustain us under the illusion that we are keeping prices down, through intensive farming, drainage of bogs, clearing forests and turning rivers into canals. As Tony Juniper's new analysis shows, however, the ways in which we meet our needs often doesn't make economic sense. Through vivid first hand accounts and inspirational examples of how the damage is being repaired, Juniper takes readers on a journey to a different Britain from the one many assume we inhabit, not a country where nature is worthless or an impediment to progress, but the real Britain, the one where we are supported by nature, wildlife and natural systems at almost every turn.

    In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. As Zuk argues, such beliefs incorrectly assume that we’re stuck—finished evolving—and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults’ ability to drink milk to the texture of our ear wax to show that we’ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were “meant to” fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs.From debunking the caveman diet to unraveling gender stereotypes, Zuk gives an analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future.

    It hangs on everyone's lips from the first miles of the morning commute until the screeching alarm clock starts yet another day. Countless articles and studies tell the same story: lives controlled by unmanaged stress end early and none too well. This book describes a simple, straightforward method readers can learn and practice to literally transform stress by shifting the heart's own rhythms.At the core of the HeartMath method of emotional regulation is the idea that, by focusing on positive feelings such as appreciation, care, or compassion, anyone can create dramatic changes in his or her heart rhythms. These changes precipitate a series of neural, hormonal, and biochemical events that dissipate stress and anger and lead to greater well-being. The benefits from using this system are remarkable and far-reaching: blood pressure drops, stress hormone levels fall, immune system activity increases, and anti-aging hormone levels rise. Through its interactive learning system, this book teaches readers to use the HeartMath method, enabling them to see and experience in real time how thoughts and emotions affect their heart rhythms. It teaches them how to engage their hearts to bring emotion, body, and mind into balance, and helps them stay in a zone of focused clarity, optimal health, and high performance. Changes brought about through this method are fast-acting and long-lasting, the perfect antidote to our chaotic and fast-paced lives.HeartMath is a registered trademark of the Institute of HeartMath.

    The experience of an apiary slows our sense of time, heightens our awareness, and inspires awe. Bee Time" presents Winston s reflections on three decades spent studying these creatures, and on the lessons they can teach about how humans might better interact with one another and the natural world.Like us, honeybees represent a pinnacle of animal sociality. How they submerge individual needs into the colony collective provides a lens through which to ponder human societies. Winston explains how bees process information, structure work, and communicate, and examines how corporate boardrooms are using bee societies as a model to improve collaboration. He investigates how bees have altered our understanding of agricultural ecosystems and how urban planners are looking to bees in designing more nature-friendly cities.The relationship between bees and people has not always been benign. Bee populations are diminishing due to human impact, and we cannot afford to ignore what the demise of bees tells us about our own tenuous affiliation with nature. Toxic interactions between pesticides and bee diseases have been particularly harmful, foreshadowing similar effects of pesticides on human health. There is much to learn from bees in how they respond to these challenges. In sustaining their societies, bees teach us ways to sustain our own."

    The book emphasizes a general introduction to probability theory and provides a detailed discussion of specific designs and analyses that are typically encountered in ecology and environmental science. Appropriate for use as either a stand-alone or supplementary text for upper-division undergraduate or graduate courses in ecological and environmental statistics, ecology, environmental science, environmental studies, or experimental design, the Primer also serves as a resource for environmental professionals who need to use and interpret statistics daily but have little or no formal training in the subject.

    In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life.We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

    Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites--from New Jersey's Cape May to California's Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away.Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen.Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail--the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits.For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle--distilling an expert's years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species--is quite simply a must.Key Features? The essential new approach to identifying hawks in flight Innovative, accurate, and field-tested identification traits for each species 339 color photos on 68 color plates, 32 black & white photos Compares and contrasts species easily confused with one another, and provides the pictures (and words) needed for identification in the field Covers in detail 19 species common to migration sites throughout the North America Discusses light conditions, how molt can alter the shape of a bird, aberrant plumages, and migration seasons and sites User-friendly format
