Objects in harmonic motion have the ability to transfer some of their energy over large distances. Light Nature: This chapter covers the nature of light, polarization, and color.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    And unlike dogs, cats offer humans no practical benefit. The truth is they are sadly incompetent mouse-catchers and now pose a threat to many ecosystems. Yet, we love them still.Content:Catacombs Cat's cradle What's the catch? The cats that ate the canaries The cat lobby CAT scan Pandora's litter box Lions and toygers and lykoi Nine likes.

    Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism.Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world.

    There's no need to look through dozens of photos of birds that don't live in Minnesota. This book features 111 species of Minnesota birds, organized by color for ease of use. Do you see a yellow bird and don't know what it is? Go to the yellow section to find out. Fact-filled information, a compare feature, range maps and detailed photographs help to ensure that you positively identify the birds that you see.

    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.

    Bursting with all the suspense and intrigue of a fast paced adventure novel, here is Johanson’s lively account of the extraordinary discovery of “Lucy.” By expounding the controversial change Lucy makes in our view of human origins, Johanson provides a vivid, behind-the-scenes account of the history of pealeoanthropology and the colorful, eccentric characters who were and are a part of it. Never before have the mystery and intricacy of our origins been so clearly and compellingly explained as in this astonighing and dramatic book.

    In this extraordinary feat of nature writing, we meet ants who harvest crops, raise insects as livestock, build roadways and bridges, embark on nuptial flights, and make war.

    Although there are more than thirty thousand species of fish—more than all mammals, birds, reptiles, and amphibians combined—we rarely consider how individual fishes think, feel, and behave. Balcombe upends our assumptions about fishes, portraying them not as unfeeling, dead-eyed feeding machines but as sentient, aware, social, and even Machiavellian—in other words, much like us. What a Fish Knows draws on the latest science to present a fresh look at these remarkable creatures in all their breathtaking diversity and beauty. Fishes conduct elaborate courtship rituals and develop lifelong bonds with shoalmates. They also plan, hunt cooperatively, use tools, curry favor, deceive one another, and punish wrongdoers. We may imagine that fishes lead simple, fleeting lives—a mode of existence that boils down to a place on the food chain, rote spawning, and lots of aimless swimming. But, as Balcombe demonstrates, the truth is far richer and more complex, worthy of the grandest social novel. Highlighting breakthrough discoveries from fish enthusiasts and scientists around the world and pondering his own encounters with fishes, Balcombe examines the fascinating means by which fishes gain knowledge of the places they inhabit, from shallow tide pools to the deepest reaches of the ocean. Teeming with insights and exciting discoveries, What a Fish Knows offers a thoughtful appraisal of our relationships with fishes and inspires us to take a more enlightened view of the planet’s increasingly imperiled marine life. What a Fish Knows will forever change how we see our aquatic cousins—the pet goldfish included.

    They live everywhere—deep inside caves, 18,000 feet high in the Himalayas, inside computers, in Yellowstone’s hot springs, and in the ears and nostrils of much larger creatures. There are insects that have ears on their knees, eyes on their penises, and tongues under their feet. Most of us think life would be better without bugs. In fact, life would be impossible without them. Most of us know that we would not have honey without honeybees, but without the pinhead-sized chocolate midge, cocoa flowers would not pollinate. No cocoa, no chocolate. The ink that was used to write the Declaration of Independence was derived from galls on oak trees, which are induced by a small wasp. The fruit fly was essential to medical and biological research experiments that resulted in six Nobel prizes. Blowfly larva can clean difficult wounds; flour beetle larva can digest plastic; several species of insects have been essential to the development of antibiotics. Insects turn dead plants and animals into soil. They pollinate flowers, including crops that we depend on. They provide food for other animals, such as birds and bats. They control organisms that are harmful to humans. Life as we know it depends on these small creatures. With ecologist Anne Sverdrup-Thygeson as our capable, entertaining guide into the insect world, we’ll learn that there is more variety among insects than we can even imagine and the more you learn about insects, the more fascinating they become. Buzz, Sting, Bite is an essential introduction to the little creatures that make the world go round.

    In Darwin Comes to Town, evolutionary biologist Menno Schilthuizen shows that evolution can in fact happen extremely quickly, and in the strangest of places: the heart of the city.Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating the evolution of the animals and plants around us. Cities are extreme environments and, in a world of adapt or die, the wildlife sharing these spaces with us is being forced to adopt fascinating new ways of surviving, and often thriving.--Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts.--Spiders in Vienna are adapting to build their webs near moth-attracting streetlights, while moths in some cities are developing a resistance to the lure of light bulbs.--Certain Puerto Rican city lizards are evolving feet that better grip surfaces like concrete.--Europe’s urban blackbirds sing at a higher pitch than their rural cousins, to be heard over the din of traffic, while many pigeons have eschewed traveling “as the crow flies” in favor of following manmade roads.Darwin Comes to Town draws on these and other eye-popping examples to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward overpopulation might not take the rest of nature down with us.

    Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses. Robin Wall Kimmerer's book is not an identification guide, nor is it a scientific treatise. Rather, it is a series of linked personal essays that will lead general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings, from salmon and hummingbirds to redwoods and rednecks. Kimmerer clearly and artfully explains the biology of mosses, while at the same time reflecting on what these fascinating organisms have to teach us.Drawing on her diverse experiences as a scientist, mother, teacher, and writer of Native American heritage, Kimmerer explains the stories of mosses in scientific terms as well as in the framework of indigenous ways of knowing. In her book, the natural history and cultural relationships of mosses become a powerful metaphor for ways of living in the world.Gathering Moss will appeal to a wide range of readers, from bryologists to those interested in natural history and the environment, Native Americans, and contemporary nature and science writing.

    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.

    As the news gradually seeped out of the USSR and the extent of the disaster was realized, it became clear how horribly wrong things had gone. Dozens died - two from the explosion and many more from radiation illness during the following months - while scores of additional victims came down with acute radiation sickness. Hundreds of thousands were evacuated from the most contaminated areas. The prognosis for Chernobyl and its environs - succinctly dubbed the Zone of Alienation - was grim.Today, 20 years after the worst nuclear power plant accident in history, intrepid journalist Mary Mycio dons dosimeter and camouflage protective gear to explore the world's most infamous radioactive wilderness. As she tours the Zone to report on the disaster's long-term effects on its human, faunal, and floral inhabitants, she meets pockets of defiant local residents who have remained behind to survive and make a life in the Zone. And she is shocked to discover that the area surrounding Chernobyl has become Europe's largest wildlife sanctuary, a flourishing - at times unearthly - wilderness teeming with large animals and a variety of birds, many of them members of rare and endangered species. Like the forests, fields, and swamps of their unexpectedly inviting habitat, both the people and the animals are all radioactive. Cesium-137 is packed in their muscles and strontium-90 in their bones. But quite astonishingly, they are also thriving.If fears of the Apocalypse and a lifeless, barren radioactive future have been constant companions of the nuclear age, Chernobyl now shows us a different view of the future. A vivid blend of reportage, popular science, and illuminating encounters that explode the myths of Chernobyl with facts that are at once beautiful and horrible, Wormwood Forest brings a remarkable land - and its people and animals - to life to tell a unique story of science, surprise and suspense.
