Dyr i naturen

  • Kan den prutte? af Dani Rabaiotti
    - Den ultimative feltguide til dyreflatulens
    af Dani Rabaiotti & Nick Caruso

    Hunde gør det. Tusindben gør det. Og dinosaurerne gjorde det. Du gør det. Blæksprutter gør det ikke. Måske gør edderkopper det, men det kræver mere forskning. Fugle gør det ikke, men de kunne, hvis de ville. Sild gør det, men kun for at kommunikere med hinanden. Denne bog er den ultimative guide til dyreflatulens, og du får al den viden, som du ikke vidste, du havde brug for om 80 meget forskellige dyrearter: Hvorfor lugter hyænens prutter ekstra fælt? Hvad er en fossa - og prutter den? Og hvad er en prut egentlig? Det svarer en række biologer på i denne videnskabelig, sober og vanvittig underholdende bog. Til læsere i alle aldre Dani Rabaiotto er zoolog. Nick Caruso er økolog og forsker. 

  • Peregrine: The Hill of Summer & Diaries: The Complete Works of J. A. Baker af J. A. Baker
    af J. A. Baker

    J. A. Baker's extraordinary classic of British nature writingDespite the association of peregrines with the wild, outer reaches of the British Isles, The Peregrine is set on the flat marshes of the Essex coast, where J A Baker spent a long winter looking and writing about the visitors from the uplands - peregrines that spend the winter hunting the huge flocks of pigeons and waders that share the desolate landscape with them.Including original diaries from which The Peregrine was written and its companion volume The Hill of Summer, this is a beautiful compendium of lyrical nature writing at its absolute best. Such luminaries as Richard Mabey, Robert Macfarlane, Ted Hughes and Andrew Motion have cited this as one of the most important books in 20th Century nature writing, and the bestselling author Mark Cocker has provided an introduction on the importance of Baker, his writings and the diaries - creating the essential volume of Baker's writings.Papers, maps, and letters have recently come to light which in turn provide a little more background into J A Baker's history. Contemporaries - particularly from his time at school in Chelmsford - have provided insights, remembering a school friend who clearly made an impact on his generation.Among fragments of letters to Baker was one from a reader who praised a piece that Baker had written in RSPB Birds magazine in 1971. Apart from a paper on peregrines which Baker wrote for the Essex Bird Report, this article - entitled On the Essex Coast - appears to be his only other published piece of writing, and, with the agreement of the RSPB, it has been included in this updated new paperback edition of Baker's astounding work.

  • Last Chance To See af Douglas Adams
    af Douglas Adams & Mark Carwardine

    'Douglas Adams' genius was in using comedy to make serious points about the world' IndependentAfter years of reflecting on the absurdities of life on other planets, Douglas Adams teamed up with zoologist Mark Carwardine to find out what was happening to life on this one. Together they lead us on an unforgettable journey across the world in search of exotic, endangered creatures - animals that they may never get another chance to see. They encounter the animal kingdom in its stunning beauty, astonishing variety, and imminent peril: the giant Komodo dragon of Indonesia, the helpless but lovable Kakapo of New Zealand, the blind river dolphins of China, the white rhinos of Zaire, the rare birds of Mauritius island in the Indian Ocean. Both funny and poignant, Last Chance to See is the tale of an unforgettable wildlife odyssey - and a timely reminder of all that we must protect.

  • Consider the Platypus af Maggie Ryan Sandford
    - Evolution through Biology's Most Baffling Beasts
    af Maggie Ryan Sandford

    Interested in the origins of the species? Consider the Platypus uses pets such as dogs and cats as well as animal outliers like the axolotl and naked mole rat to wittily tackle mind-bending concepts about how evolution, biology, and genetics work. Consider the Platypus explores the history and features of more than 50 animals to provide insight into our current understanding of evolution. Using Darwin's theory as a springboard, Maggie Ryan Sandford details scientists' initial understanding of the development of creatures and how that has expanded in the wake of genetic sequencing, including the: Peppered Moth, which changed color based on the amount of soot in the London air;California Two-Spotted Octopus, which has the amazing ability to alter its DNA/RNA not over generations but during its lifetime;miniscule tardigrade, which is so hearty it can withstand radiation, lack of water and oxygen, and temperatures as low as -328 F and as high 304 F;and, of course, the platypus, which has so many disparate features, from a duck's bill to venomous spur to mammary patches, that scientists originally thought it was a hoax. Surprising, witty, and impeccably researched, Sandford describes each animal's significant features and how these have adapted to its environment, such as the zebra finch's beak shape, which was observed by Charles Darwin and is a cornerstone of his Theory of Evolution. With scientifically accurate but charming art by Rodica Prato, Consider the Platypus showcases species as diverse as the sloth, honey bee, cow, brown kiwi, and lungfish, to name a few, to tackle intimidating concepts is a accessible way.

  • Coyote Settles the South af John Lane Spar 13%
    af John Lane

    One night, poet and environmental writer John Lane tuned in to a sound from behind his house that he had never heard before: the nearby eerie and captivating howls of coyotes. Since this was Spartanburg, South Carolina, and not Missoula, Montana, Lane set out to discover all he could about his new and unexpected neighbors.Coyote Settles the South is the story of his journey through the Southeast, as he visits coyote territories: swamps, nature preserves, old farm fields, suburbs, a tannery, and even city streets. On his travels he meets, interrogates, and observes those who interact with the animalstrappers, wildlife researchers, hunters, rattled pet owners, and even one devoted coyote hugger. Along the way, he encounters sensible, yet sometimes perplexing, insight concerning the migration into the Southeast of the American coyote, an animal that, in the end, surprises him with its intelligence, resilience, and amazing adaptability.

  • Landscape with Reptile af Thomas Palmer Spar 13%
    - Rattlesnakes in an Urban World
    af Thomas Palmer

    In this authoritative and entertaining book, first published in 1992, Thomas Palmer introduces us to a community of rattlesnakes nestled in the heart of the urban Northeast, one of several such enclaves found near cities across the United States. Recognizing the unexpected proximity of rattlers in our urban environs, Palmer examines not only Crotalus horridus but also the ecology, evolution, folklore, New England history, and American culture that surrounds this native species.Landscape with Reptile celebrates the rattlesnake's survival with a multifaceted journey through nature, literature, and history. It includes a spirited defense of an outlaw species, an investigation of the hazards of snakebite, an account of a multimillion-dollar development project halted by Crotalus, a collection of tall tales, and a meditation on the spectacle of life on earth. Like the best nature writers, Palmer lives and breathes his landscape, but unlike most nature writers, he finds his landscape is his own backyard. Rarely has a book of natural history addressed so many historical and cultural touchstones in such original and unexpected ways. Palmer's story is as authentic as the woodlands from which it sprang.

  • Pandora's Garden af Clinton Crockett Peters Spar 13%
    - Kudzu, Cockroaches, and Other Misfits of Ecology
    af Clinton Crockett Peters

    Pandora's Garden profiles invasive or unwanted species in the natural world and examines how our treatment of these creatures sometimes parallels in surprising ways how we treat each other. Part essay, part nature writing, part narrative nonfiction, the chapters in Pandora's Garden are like the biospheres of the globe; as the successive chapters unfold, they blend together like ecotones, creating a microcosm of the world in which we sustain nonhuman lives but also contain them.There are many reasons particular flora and fauna may be unwanted, from the physical to the psychological. Sometimes they may possess inherent qualities that when revealed help us to interrogate human perception and our relationship to an unwanted other. Pandora's Garden is primarily about creatures that humans don't get along with, such as rattlesnakes and sharks, but the chapters also take on a range of other subjects, including stolen children in Australia, the treatment of illegal immigrants in Texas, and the disgust function of the human limbic system. Peters interweaves these diverse subjects into a whole that mirrors the evolving and interrelated world whose surprises and oddities he delights in revealing.

  • Livestock af Erin McKenna Spar 13%
    - Food, Fiber, and Friends
    af Erin McKenna

    Most livestock in America currently live in cramped and unhealthy confinement, have few stable social relationships with humans or others of their species, and finish their lives by being transported and killed under stressful conditions. In Livestock, Erin McKenna allows us to see this situation and presents alternatives. She interweaves stories from visits to farms, interviews with producers and activists, and other rich material about the current condition of livestock. In addition, she mixes her account with pragmatist and ecofeminist theorizing about animals, drawing in particular on John Deweys account of evolutionary history, and provides substantial historical background about individual species and about human-animal relations.This deeply informative text reveals that the animals we commonly see as livestock have rich evolutionary histories, species-specific behaviors, breed tendencies, and individual variation, just as those we respect in companion animals such as dogs, cats, and horses. To restore a similar level of respect for livestock, McKenna examines ways we can balance the needs of our livestock animals with the environmental and social impacts of raising them, and she investigates new possibilities for human ways of being in relationships with animals. This book thus offers us a picture of healthier, more respectful relationships with livestock.

Composed of sailfish, marlin, spearfish, and swordfish, they roam the pelagic waters of the Atlantic and are easily recognized by their long, spear-like beaks. Noted for their speed, size, and acrobatic jumps, billfish have for centuries inspired a broad spectrum of society. Even in antiquity, Aristotle, who assiduously studied the swordfish, named this gladiator of the sea xiphiasthe sword.</p><p><i>The Billfish Story</i> tells the saga of this unique group of fish and those who have formed bonds with themrelationships forged by anglers, biologists, charter-boat captains, and conservationists through their pursuit, study, and protection of these species.

    Before the novel and the film Deliverance appeared in the early 1970s, any outsiders one met along the Chattooga River were likely serious canoeists or anglers. In later years, untold numbers and kinds of people have felt the draw of the river's torrents, which pour down the Appalachians along the Georgia-South Carolina border. Because of Deliverance the Chattooga looms enigmatically in our shared imagination, as iconic as Twain's Mississippior maybe Conrad's Congo.This is John Lane's search for the real Chattoogafor the truths that reside somewhere in the river's rapids, along its shores, or in its travelers' hearts. Lane balances the dark, indifferent mythical river of Deliverance against the Chattooga known to locals and to the outdoors enthusiasts who first mastered its treacherous vortices and hydraulics. Starting at its headwaters, Lane leads us down the river and through its complex history to its current status as a National Wild and Scenic River. Along the way he stops for talks with conservation activists, seventh-generation residents, locals who played parts in the movie, day visitors, and others. Lane weaves into each encounter an abundance of details drawn from his perceptive readings and viewings of Deliverance and his wide-ranging knowledge of the Chattooga watershed. At the end of his run, Lane leaves us still fully possessed by the Chattooga's mystery, yet better informed about its place in his world and ours.

  • Fields and Streams af Rebecca Lave Spar 13%
    - Stream Restoration, Neoliberalism, and the Future of Environmental Science
    af Rebecca Lave

    Examining the science of stream restoration, Rebecca Lave argues that the neoliberal emphasis on the privatization and commercialization of knowledge has fundamentally changed the way that science is funded, organized, and viewed in the United States.Stream restoration science and practice is in a startling state. The most widely respected expert in the field, Dave Rosgen, is a private consultant with relatively little formal scientific training. Since the mid-1990s, many academic and federal agencybased scientists have denounced Rosgen as a charlatan and a hack. Despite this, Rosgens Natural Channel Design approach, classification system, and short-course series are not only accepted but are viewed as more legitimate than academically produced knowledge and training. Rosgens methods are now promoted by federal agencies including the Environmental Protection Agency, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Natural Resources Conservation Service, as well as by resource agencies in dozens of states.Drawing on the work of Pierre Bourdieu, Lave demonstrates that the primary cause of Rosgens success is neither the method nor the man but is instead the assignment of a new legitimacy to scientific claims developed outside the academy, concurrent with academic scientists decreasing ability to defend their turf. What is at stake in the Rosgen wars, argues Lave, is not just the ecological health of our rivers and streams but the very future of environmental science.

    <p>Written by two of the Southeasts foremost authorities on sea turtle conservation, this is an accessible, fully illustrated guide to the species that frequent the Atlantic and Gulf Coasts of the United States.</p><p>No one who encounters a sea turtle soon forgets it. The leatherback, for instance, can grow to huge proportions, commonly approaching eight feet in length and more than half a ton in weight. Powerful swimmers, they are also among the deepest divers of all air-breathing sea creatures. Despite these assets, the survival of the leatherback, like that of all sea turtle species, is under constant threat from commercial fishing operations, overdevelopment of nesting grounds, pollution, and predation by introduced species.</p><p>The guide opens with comprehensive coverage of the sea turtles evolution, juvenile and adult life cycles, nesting, diet and feeding, disease and parasites, predators, and conservation issues. Each subsequent chapter is dedicated to a particular turtle species: loggerhead, leatherback, Kemps ridley, green sea turtle, hawksbill, and olive ridley. The account of each species describes distribution, habitats, general appearance, life history and behavior, and conservation. For each species, photographs of hatchlings and adults and a map showing distribution and migration provide further information.</p><p>Sea turtles have been swimming the seas for one hundred million years. Yet all of the species in this book&mdash;indeed, all sea turtles worldwide&mdash;are on U.S. and international endangered lists. Biologists Carol Ruckdeschel and C.

    <p>Janisse Ray was a babe in arms when a boat of her father&rsquo;s construction cracked open and went down in the mighty Altamaha River. Tucked in a life preserver, she washed onto a sandbar as the craft sank from view. That first baptism began a lifelong relationship with a stunning and powerful river that almost nobody knows.</p><p>The Altamaha rises dark and mysterious in southeast Georgia. It is deep and wide bordered by swamps. Its corridor contains an extraordinary biodi&shy;versity, including many rare and endangered species, which led the Nature Conservancy to designate it as one of the world&rsquo;s last great places.</p><p>The Altamaha is Ray&rsquo;s river, and from childhood she dreamed of paddling its entire length to where it empties into the sea. <i>Drifting into Darien</i> begins with an account of finally making that journey, turning to medita&shy;tions on the many ways we accept a world that contains both good and evil. With praise, biting satire, and hope, Ray contemplates transformation and attempts with every page to settle peacefully into the now.</p><p>Though commemorating a history that includes logging, Ray celebrates &ldquo;a culture that sprang from the flatwoods, which required a judicious use of nature.&rdquo; She looks in vain for an ivorybill woodpecker but is equally eager to see any of the imperiled species found in the river basin: spiny mussel, American oystercatcher, Radford&rsquo;s mint, Alabama milkvine. The book explores both the need and the possibilities for conservation of the river and the surrounding forests and wetlands. As in her groundbreaking <i>Ecology of a Cracker Childhood</i>, Ray writes an account of her beloved river that is both social history and natural history, understanding the two as inseparable, particularly in the rural corner of Georgia that she knows best.

    First explored by naturalist William Bartram in the 1760s, the St. Johns River stretches 310 miles along Florida's east coast, making it the longest river in the state. The first highway through the once wild interior of Florida, the St. Johns may appear ordinary, but within its banks are some of the most fascinating natural phenomena and historic mysteries in the state. The river, no longer the commercial resource it once was, is now largely ignored by Florida's residents and visitors alike.In the first contemporary book about this American Heritage River, Bill Belleville describes his journey down the length of the St. Johns, kayaking, boating, hiking its riverbanks, diving its springs, and exploring its underwater caves. He rediscovers the natural Florida and establishes his connection with a place once loved for its untamed beauty. Belleville involves scientists, environmentalists, fishermen, cave divers, and folk historians in his journey, soliciting their companionship and their expertise. River of Lakes weaves together the biological, cultural, anthropological, archaeological, and ecological aspects of the St. Johns, capturing the essence of its remarkable history and intrinsic value as a natural wonder.

    <p>In the fall of 1996 Sydney Plum encountered a solitary Canada goose on a pond near her home in New England. Caring for the animal became a way for her to reconnect with nature. Walks to the pond were daily rituals&mdash;reflective times during which Plum thought about the relationships between humans and animals. Mixing memoir with closely observed nature writing, Plum searches for a deeper understanding of what was changed by the experience with the solitary goose she named SG.</p><p>In the tradition of Elizabeth Marshall Thomas, Plum writes lyrical lessons on the life cycle of geese, the mystery of their great migratory patterns, and their amazing adaptability. Canada geese were not always so plentiful in the United States, she explains, nor were they always denigrated as "e;flying carp."e; Plum shows how species-management programs reestablished the birds outside their previous range at the same time as golf courses, office parks, and suburban ponds began dotting the countryside, providing them with prime habitats where they were unwanted.</p><p>Memories of breaking holes in the ice for SG to escape predators turn Plums thoughts toward what it means to nurture. Coming to terms with how SG thinks leads Plum to examine anthropomorphism in nature writing. In contrast to the metaphors through which we commonly view nature, Plum argues that science combined with metaphor is a better way to understand animals. Though Plums focus is generously outward toward nature, this book also reveals an inner journey through which, as she describes it, "e;the enclosures of my human life had been opened. I had become more susceptible to the kindnesses of birds."e;</p>

    Geography, politics, and other factors have allowed Cuba to preserve the regions most pristine coast and offshore marine environment. Deep Cuba recounts Bill Bellevilles month-long journey around the island in the company of American and Cuban marine biologists and a Discovery Channel film crew. It was the first, and so far only, United States submersible research expedition in Cuban waters. From coral reefs to mangrove swamps to a submerged volcanic mountain, the voyagers encountered sublimely wild places unseen before by anyone from the United Statesmdash;or even by many Cubans.Belleville conveys the tempo of the scientists workday, during which the routine gathering of data and specimens could be punctuated by trips in a state-of-the-art submersible, the discovery of new species, or a tropical storm. Throughout the trip, as well, all on board had to work through differences that arose from the expeditions contrary goals: to produce a commercially viable seagoing adventure film and to conduct controlled, methodical scientific investigations.Belleville paces his coverage of the expedition with absorbing stories about the history and culture of the islands peoples, from the indigenous Taino to its current inhabitants of African and European heritage. Deep Cuba even includes a candid portrait of Castro himself. An avid diver, sport fisherman, and naturalist, El Comandante paid a visit aboard the research vessel.Deep Cuba is an engaging mix of nature and travel writing, along with scientific reportage that is keenly attuned to current crises in research funding. Revealed here is a magnificent marine world with crucial ecological links to the Caribbean Basin and the southeastern United States.

  • Reptile Ear af Ernest Glen Wever Spar 19%
    af Ernest Glen Wever

    In this definitive work, Ernest Glen Wever establishes the evolutionary importance of the reptile ear as the origin of the higher type of auditory apparatus shared by man and the mammals. Tracing the development of the auditory receptor in the living reptiles, he examines the use of a variety of mechanisms and principles of action by that receptor. While some of the material in this book has appeared previously in journal articles, most of it is presented here for the first time.Basing this study on his twenty years of research at Princeton's Auditory Research Laboratories, Professor Wever treats in anatomical and functional detail the auditory mechanism in about 250 species and subspecies of reptiles. The anatomical treatment rests on dissections and histological examinations of the ears in serial section, and portrays the relevant features in drawings that represent particular views of reconstructions. The author evaluates the performance of thesse ears electrophysiologically, in terms of the electrical potentials of the cochlea, paying particular attention to problems of the transmission of vibrations inward to the cochlea and the actions there in stimulating the sensory cells.Professor Wever finds that the cochlea emerged independently from the non-auditory labyrinth in three different vertebrate groups: fishes, amphibians, and reptiles. It was among the reptiles, however, that the vertebrate ear took on a more advanced configuration from which it further evolved along separate lineages in the birds and mammals.Ernest Glen Wever is Eugene Higgins Professor of Psychology Emeritus at Princeton University.Originally published in 1978.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

  • Birds in Winter af Roger F. Pasquier Spar 18%
    - Surviving the Most Challenging Season
    af Roger F. Pasquier

    How birds have evolved and adapted to survive winterBirds in Winter is the first book devoted to the ecology and behavior of birds during this most challenging season. Birds remaining in regions with cold weather must cope with much shorter days to find food and shelter even as they need to avoid predators and stay warm through the long nights, while migrants to the tropics must fit into very different ecosystems and communities of resident birds. Roger Pasquier explores how winter affects birds' lives all through the year, starting in late summer, when some begin caching food to retrieve months later and others form social groups lasting into the next spring. During winter some birds are already pairing up for the following breeding season, so health through the winter contributes to nesting success.Today, rapidly advancing technologies are enabling scientists to track individual birds through their daily and annual movements at home and across oceans and hemispheres, revealing new and unexpected information about their lives and interactions. But, as Birds in Winter shows, much is visible to any interested observer. Pasquier describes the season's distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Finally, global warming is altering the nature of winter itself. Whether birds that have evolved over millennia to survive this season can now adjust to a rapidly changing climate is a problem all people who enjoy watching them must consider.Filled with elegant line drawings by artist and illustrator Margaret La Farge, Birds in Winter describes how winter influences the lives of birds from the poles to the equator.

  • Galapagos af Michael Weisberg Spar 19%
    - Life in Motion
    af Michael Weisberg & Walter Perez

    A lavish photographic celebration that captures the fascinating behaviors of land and sea animals in the Galapagos IslandsThe Galapagos Islands are home to an amazing variety of iconic creatures, from Giant Tortoises, Galapagos Sea Lions, Galapagos Penguins, and Ghost Crabs to Darwin's finches, the Blue-footed Booby, and Hummingbird Moths. But how precisely do these animals manage to survive on-and in the waters around-their desert-like volcanic islands, where fresh water is always scarce, food is often hard to come by, and finding a good mate is a challenge because animal populations are so small? In this stunning large-format book, Galapagos experts Walter Perez and Michael Weisberg present an unprecedented photographic account of the remarkable survival behaviors of these beautiful and unique animals. With more than 200 detailed, close-up photographs, the book captures Galapagos animals in action as they feed, play, fight, court, mate, build nests, give birth, raise their young, and cooperate and clash with other species.Watch male Marine Iguanas fight over territory and females; see frigatebirds steal food and nesting materials from other birds; witness the courtship dance of a pair of Blue-footed Boobies; go underwater to glimpse a Galapagos Sea Lion pup playing with its mother; and observe a baby Pacific Green Turtle enter the water for the first time. These and dozens of other unforgettable scenes are all vividly captured here-including many moments that even experienced Galapagos observers may never be lucky enough to see in person.Complete with a brief text that provides essential context, this book will be cherished by Galapagos visitors and anyone else who wants to see incredible animals on the move.

    - A Scientist's Quest to Save a Rare and Vanishing Creature
    af Nick Haddad

    A remarkable look at the rarest butterflies, how global changes threaten their existence, and how we can bring them back from near-extinctionMost of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender's Blue? Or the St. Francis' Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures-some numbering no more than what can be held in one hand. Drawing from his own first-hand experiences, Nick Haddad explores the challenges of tracking these vanishing butterflies, why they are disappearing, and why they are worth saving. He also provides startling insights into the effects of human activity and environmental change on the planet's biodiversity.Weaving a vivid and personal narrative with ideas from ecology and conservation, Haddad illustrates the race against time to reverse the decline of six butterfly species. Many scientists mistakenly assume we fully understand butterflies' natural histories. Yet, as with the Large Blue in England, we too often know too little and the conservation consequences are dire. Haddad argues that a hands-off approach is not effective and that in many instances, like for the Fender's Blue and Bay Checkerspot, active and aggressive management is necessary. With deliberate conservation, rare butterflies can coexist with people, inhabit urban fringes, and, in the case of the St. Francis' Satyr, even reside on bomb ranges and military land. Haddad shows that through the efforts to protect and restore butterflies, we might learn how to successfully confront conservation issues for all animals and plants.A moving account of extinction, recovery, and hope, The Last Butterflies demonstrates the great value of these beautiful insects to science, conservation, and people.
