Any time a tree dies or a new one sprouts, the forest that includes it has shifted. When new trees sprout in the same direction, the whole forest begins to migrate, sometimes at astonishing rates. Today, however, an array of obstacles—humans felling trees by the billions, invasive pests transported through global trade—threaten to overwhelm these vital movements. Worst of all, the climate is changing faster than ever before, and forests are struggling to keep up.A deft blend of science reporting and travel writing, The Journeys of Trees explores the evolving movements of forests by focusing on five trees: giant sequoia, ash, black spruce, Florida torreya, and Monterey pine. Journalist Zach St. George visits these trees in forests across continents, finding sequoias losing their needles in California, fossil records showing the paths of ancient forests in Alaska, domesticated pines in New Zealand, and tender new sprouts of blight-resistant American chestnuts in New Hampshire. Everywhere he goes, St. George meets lively people on conservation’s front lines, from an ecologist studying droughts to an evolutionary evangelist with plans to save a dying species. He treks through the woods with activists, biologists, and foresters, each with their own role to play in the fight for the uncertain future of our environment.An eye-opening investigation into forest migration past and present, The Journeys of Trees examines how we can all help our trees, and our planet, survive and thrive.

    As she grows into adulthood, only a few of her eggs mature, are released into the oviduct, and are fertilized by sperm stored from copulation that took place days or weeks earlier. Within a matter of hours, the fragile yolk is surrounded by albumen and the whole is gradually encased within a turquoise jewel of a shell. Soon afterward the fully formed egg is expelled onto a bare rocky ledge, where it will be incubated for four weeks before another chick emerges and the life cycle begins again. The Most Perfect Thing is about how eggs in general are made, fertilized, developed, and hatched. The eggs of most birds spend just 24 hours in the oviduct; however, that journey takes 48 hours in cuckoos, which surreptitiously lay their eggs in the nests of other birds. From the earliest times, the study of birds' ovaries and ova (eggs) played a vital role in the quest to unravel the mysteries of fertilization and embryo development in humans. Birkhead uses birds' eggs as wondrous portals into natural history, enlivened by the stories of naturalists and scientists, including Birkhead and his students, whose discoveries have advanced current scientific knowledge of reproduction.

    They maintain the atmosphere by absorbing carbon dioxide and producing oxygen. They nourish other living organisms and supply psychological benefits to humans as well, improving our moods and beautifying the landscape around us. But plants don't just passively provide. They also take action.Beronda L. Montgomery explores the vigorous, creative lives of organisms often treated as static and predictable. In fact, plants are masters of adaptation. They "know" what and who they are, and they use this knowledge to make a way in the world. Plants experience a kind of sensation that does not require eyes or ears. They distinguish kin, friend, and foe, and they are able to respond to ecological competition despite lacking the capacity of fight-or-flight. Plants are even capable of transformative behaviors that allow them to maximize their chances of survival in a dynamic and sometimes unfriendly environment.Lessons from Plants enters into the depth of botanic experience and shows how we might improve human society by better appreciating not just what plants give us but also how they achieve their own purposes. What would it mean to learn from these organisms, to become more aware of our environments and to adapt to our own worlds by calling on perception and awareness? Montgomery's meditative study puts before us a question with the power to reframe the way we live: What would a plant do?

    The extraordinary brilliance of her eye confers the reader a total immersion in the rimy realms she explores. Glaciers, Arctic floe, verglas, frost and snow — I can think of no better or warmer guide to the icy ends of the Earth’ Dan Richards, author of Climbing DaysA vivid and perceptive book combining memoir, scientific and cultural history with a bewitching account of landscape and place, which will appeal to readers of Robert Macfarlane, Roger Deakin and Olivia Laing.  Long captivated by the solid yet impermanent nature of ice, by its stark, rugged beauty, acclaimed poet and writer Nancy Campbell sets out from the world’s northernmost museum – at Upernavik in Greenland – to explore it in all its facets. From the Bodleian Library archives to the traces left by the great polar expeditions, from remote Arctic settlements to the ice houses of Calcutta, she examines the impact of ice on our lives at a time when it is itself under threat from climate change. The Library of Ice is a fascinating and beautifully rendered evocation of the interplay of people and their environment on a fragile planet, and of a writer’s quest to define the value of her work in a disappearing landscape.‘The Library of Ice instantly transported me elsewhere... This luminous book is both beautifully written and astute in its observations, turning the pages of time backwards and revealing, like the archive of the earth’s climate stored in layers of solidified water, the embedded meanings of the world’s icy realms. It is a book as urgently relevant as it is wondrous’ Julian Hoffman, author of The Heart of Small Things ‘An extraordinary work not only for the perspicacity and innate experience of the author who leads the reader carefully across intertwined icy tracks of crystallised geographics, melting myths and frozen exploration histories, but through her own tender diagnostics of what reading ice can show us in these times … Perilous in its scope, exacting in its observation, wild in intellect, The Library of Ice captures the reader’s attention almost as if caught in ice itself’ Kirsten Macgillivray, poet   ‘This is travel writing to be treasured. A biography of ice, the element that has another life, with hard facts thawed and warmed by a poet's voice. Campbell's writing is companionable, curious, deeply researched and with no bragging about the intrepidity that has taken her between winter-dark Greenland, Polar libaries, Scottish curling rinks, Alpine glaciers and Henry Thoreau's pond at Walden’ Jasper Winn, author of Paddle

    On packaged food, restaurant menus, and online recipes we see authoritative numbers that tell us the calorie count of what we're about to consume. And we treat these numbers as gospel—counting, cutting, intermittently consuming and, if you believe some 'experts' out there, magically making them disappear. We all know, and governments advise, that losing weight is just a matter of burning more calories than we consume.  But it's actually all wrong. In Why Calories Don't Count, Dr. Giles Yeo, an obesity researcher at Cambridge University, challenges the conventional model and demonstrates that all calories are not created equal. He addresses why popular diets succeed, at least in the short term, and why they ultimately fail, and what your environment has to do with your bodyweight. Once you understand that calories don't count, you can begin to make different decisions about how you choose to eat, learning what you really need to be counting instead. Practical, science-based and full of illuminating anecdotes, this is the most entertaining dietary advice you'll ever read.

    Drawing upon a lifetime of scientific expertise and abiding love of nature, Fortey uses his small wood to tell a wider story of the ever-changing British landscape, human influence on the countryside over many centuries and the vital interactions between flora, fauna and fungi.The trees provide a majestic stage for woodland animals and plants to reveal their own stories. Fortey presents his wood as an interwoven collection of different habitats rich in species. His attention ranges from the beech and cherry trees that dominate the wood to the flints underfoot; the red kites and woodpeckers that soar overhead; the lichens, mosses and liverworts decorating the branches as well as the myriad species of spiders, moths, beetles and crane-flies. The 300 species of fungi identified in the wood capture his attention as much as familiar deer, shrews and dormice.Fortey is a naturalist who believes that all organisms are as interesting as human beings – and certainly more important than the observer. So this book is a close examination of nature and human history. He proves that poetic writing is compatible with scientific precision. The book is filled with details of living animals and plants, charting the passage of the seasons, visits by fellow enthusiasts; the play of light between branches; the influence of geology; and how woodland influences history, architecture and industry. On every page he shows how an intimate study of one small wood can reveal so much about the natural world and demonstrates his relish for the incomparable pleasures of discovery.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.

    In the preface to this book, author Keith Delaplane says of his first book on beekeeping, "Its pages opened to me a golden world of honey bees and beekeeping and guided my stumbling steps that first spring season. My story is but one of thousands who have passed through the door opened by Dadant's little book."

    Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. The same goes for quantum theory, which is based on the principle that the "stuff " of the universe-matter and energy-is not infinitely divisible but comes in discrete chunks called "quanta." Profound ... Beautiful ... Relevant Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments. Consider these ideas: Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate. General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space. According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains. A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining. Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made. An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena. From Aristotle to the Theory of Everything Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests. With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time. Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language. Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. Fascinating Incidents and Ideas Along the way, you'll explore these fascinating incidents and ideas: In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis. In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity-that the laws of physics are the same for all observers in uniform motion. Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light? Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day. Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime. Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle." Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force? A Teaching Legend On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist. In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures. Professor Richard Wolfson on the Second Edition of Einstein's Relativity: "The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."

    An orangutan picks a lock to let himself out of his zoo enclosure and two elephants adopt a tag-team strategy to keep their handlers from putting them back into theirs. In The Parrot's Lament, noted environmentalist Eugene Linden offers more than one hundred true anecdotes about animal acts of cooperation, heroism, escape--even tales of deception or manipulation of human beings. Drawing on the first-person experiences of veterinarians, field biologists, researchers, and trainers, Linden has compiled a warmly entertaining and powerfully persuasive argument for animal consciousness that, while not human, far exceeds what humans usually grant animals. Scientifically sound and emotionally compelling, The Parrot's Lament contains remarkable stories that are sure to resonate with animal lovers, turning skeptics everywhere into believers.

    Gravetter, and co-author Lori-Ann B. Forzano have written a text for research methods that helps you see how interesting and exciting experimental and non-experimental research can be. Inviting and conversational, RESEARCH METHODS FOR THE BEHAVIORAL SCIENCES, Third Edition, leads you through the research process from start to finish. The text opens with tips and strategies for generating research ideas, moves to selecting measures and participants, and then offers an examination of research strategy and design. This step-by-step approach emphasizes the decisions researchers must make at each stage of the process. The authors avoid a "cookbook" approach to the facts by linking terminology with applied concepts; their "lecture in a book" style emphasizes discussion and explanation of topics. Each chapter ends with a set of exercises and activities.

    With amusing examples from film, TV, and history, learn how physics affects everything in your surroundings--without the use of mind-bending math or the need for a particle accelerator. With E=MC2, you'll learn: When forces balance: Simple answers to questions such as, "Why do balloons rise while apples fall?" The Good, the Bad, and the Impossible: Why The Good, the Bad, and the Ugly is full of absurdities. (For someone whose characters often uphold the law, Clint Eastwood certainly defies the laws of physics in this film.) AC/DC: but only AC really rocks: Alternating current (AC) is much more complicated than direct current (DC). The voltage is constantly moving between positive and negative; the current therefore flows one way, and then the other (rocking back and forth). Why do I feel this warm glow?: The theory behind how the first stars were born General Relativity and GPS: The strange result of gravity on time is well proven. Compared to the interminable time you experience while stuck in a traffic jam, time literally runs faster (because gravity is weaker) in the orbiting GPS satellites that help your GPS system get its fix.
