  • Species af John S. Wilkins E-bog Species af John S. Wilkins

    Over time the complex idea of "e;species"e; has evolved, yet its meaning is far from resolved. This comprehensive work is a fresh look at an idea central to the field of biology by tracing its history from antiquity to today. Species is a benchmark exploration and clarification of a concept fundamental to the past, present, and future of the natural sciences. In this edition, a section is added on the debate over species since the time of the New Synthesis, and brings the book up to date. A section on recent philosophical debates over species has also been added. This edition is better suited non-specialists in philosophy, so that it will be of greater use for scientists wishing to understand how the notion came to be that living organisms form species.

  • Aaaaw to Zzzzzd: The Words of Birds af John Bevis E-bog Aaaaw to Zzzzzd: The Words of Birds af John Bevis

    "A miraculous little book: a compressed encyclopedia of our fascination with avifauna." -- The Nation"A charming, funny, and eccentric book." -- Times Literary Supplement"An elegant tribute to the beauty of its subject." -- Los Angeles TimesBirds sing and call, sometimes in complex and beautiful arrangements of notes, sometimes in one-line repetitions that resemble a ringtone more than a symphony. Listening, we are stirred, transported, and even envious of birds' ability to produce what Shelley called "profuse strains of unpremeditated art." And for hundreds of years, we have tried to write down what we hear when birds sing. Poets have put birdsong in verse (Thomas Nashe: "Cuckoo, jug-jug, pu-we, to-witta-woo") and ornithologists have transcribed bird sounds more methodically. Drawing on this history of bird writing, in Aaaaw to Zzzzzd John Bevis offers a lexicon of the words of birds. For tourists in Birdland, there could be no more charming phrasebook. Consulting it, we find seven distinct variations of "hoo" attributed to seven different species of owls, from a simple hoo to the more ambitious hoo hoo hoo-hoo, ho hoo hoo-hoo; the understated cheet of the tree swallow; the resonant kreeaaaaaaaaaaar of the Swainson's hawk; the modest peep peep peep of the meadow pipit. We learn that some people hear the Baltimore oriole saying "here, here, come right here, dear" and the yellowhammer saying "a little bit of bread and no cheese." Bevis, a poet, frames his lexicons -- one for North America and one for Britain and northern Europe -- with an evocative appreciation of birds, birdsong, and human attempts to capture the words of birds in music and poetry. He also offers an engaging account of other methods of documenting birdsong -- field recording, graphic notation, and mechanical devices including duck calls and the serinette, an instrument used to teach song tunes to songbirds. The singing of birds is nature at its most sublime, and words are our medium for expressing this sublimity. Aaaaw to Zzzzzd belongs in the bird lover's backpack and on the word lover's bedside table, an unexpected and sui generis pleasure.

  • Far from Land af Michael Brooke Spar 19% E-bog Far from Land af Michael Brooke

    The lives and activities of seabirds as youve never seen them beforeSeabirds evoke the spirit of the earth's wildest places. They spend large portions of their lives at sea, often far from land, and nest on beautiful and remote islands that humans rarely visit. Thanks to the development of increasingly sophisticated and miniaturized devices that can track their every movement and behavior, it is now possible to observe the mysterious lives of these remarkable creatures as never before. This beautifully illustrated book takes you on a breathtaking journey around the globe to reveal where these birds actually go when they roam the sea, the tactics they employ to traverse vast tracts of ocean, the strategies they use to evade threats, and more.Michael Brooke has visited every corner of the world in his lifelong pursuit of seabirds. Here, he draws on his own experiences and insights as well as the latest cutting-edge science to shed light on the elusive seafaring lives of albatrosses, frigatebirds, cormorants, and other ocean wanderers. Where do puffins go in the winter? How deep do penguins dive? From how far away can an albatross spot a fishing vessel worth following for its next meal? Brooke addresses these and other questions in this delightful book. Along the way, he reveals that seabirds are not the aimless wind-tossed creatures they may appear to be and explains the observational innovations that are driving this exciting area of research.Featuring illustrations by renowned artist Bruce Pearson and packed with intriguing facts, Far from Land provides an extraordinary up-close look at the activities of seabirds.

  • In Search of the African Lion af Roger de la Harpe Spar 11% E-bog In Search of the African Lion af Roger de la Harpe & Pat de la Harpe

    The African lion (Panthera leo), long celebrated as the king of beasts, faces unprecedented challenges in the wild today. Loss of habitat through the expansion of human activity increasingly restricts the lion to game reserves and national parks, while diseases such as bovine tuberculosis pose a threat to the health of lion prides. Over a period of two years, Roger and Pat de la Harpe have documented wild lions of South Africa, and the result is a superbly photographed and engagingly written tribute to this often misunderstood predator. In Search of the African Lion enters the complex world of the lion, describing pride dynamics, hunting patterns, the reproductive cycle and interactions with human communities. The book focuses on four main areas: the Kalahari, the Madikwe/Mapungubwe area, the Greater Kruger National Park and Northern Zululand -each with its own problems, challenges and opportunities. In addition, the authors highlight the important work done by game rangers, wildlife managers and scientific researchers in understanding the lion and in protecting existing populations. The In Search of... series focuses on the plight of threatened and endangered species. Also available by the same authors: In Search of the African Wild Dog.

  • Cane Toad Wars af Rick Shine E-bog Cane Toad Wars af Rick Shine

    In 1935, an Australian government agency imported 101 specimens of the Central and South American Cane Toad in an attempt to manage insects that were decimating sugar-cane harvests. In Australia the Cane Toad adapted and evolved with abandon, voraciously consuming native wildlife and killing predators with its lethal skin toxin. Today, hundreds of millions of Cane Toads have spread across the northern part of Australia and continue to move westward. The humble Cane Toad has become a national villain. Cane Toad Wars chronicles the work of intrepid scientist Rick Shine, who has been documenting the toad's ecological impact in Australia and seeking to buffer it. Despite predictions of devastation in the wake of advancing toad hordes, the author's research reveals a more complex and nuanced story. A firsthand account of a perplexing ecological problem and an important exploration of how we measure evolutionary change and ecological resilience, this book makes an effective case for the value of long-term natural history research in informing conservation practice.

  • North on the Wing af Bruce M. Beehler Spar 28% E-bog North on the Wing af Bruce M. Beehler

    The story of an ornithologist's journey to trace the spring migration of songbirds from the southern border of the United States through the heartland and into Canada.In late March 2015, ornithologist Bruce M. Beehler set off on a solo four-month trek to track songbird migration and the northward progress of spring through America. Traveling via car, canoe, and bike and on foot, Beehler followed woodland warblers and other Neotropical songbird species from the southern border of Texas, where the birds first arrive after their winter sojourns in South America and the Caribbean, northward through the Mississippi drainage to its headwaters in Minnesota and onward to their nesting grounds in the north woods of Ontario. In North on the Wing, Beehler describes both the epic migration of songbirds across the country and the gradual dawning of springtime through the U.S. heartland--the blossoming of wildflowers, the chorusing of frogs, the leafing out of forest canopies--and also tells the stories of the people and institutions dedicated to studying and conserving the critical habitats and processes of spring songbird migration. Inspired in part by Edwin Way Teale's landmark 1951 book North with the Spring, this book--part travelogue, part field journal, and part environmental and cultural history--is a fascinating first-hand account of a once-in-a-lifetime journey. It engages readers in the wonders of spring migration and serves as a call for the need to conserve, restore, and expand bird habitats to preserve them for future generations of both birds and humans.

  • Why Every Fly Counts af Hans-Dietrich Reckhaus E-bog Why Every Fly Counts af Hans-Dietrich Reckhaus

    This book discusses the beneficial and harmful effects of insects and explains their development and significance for biodiversity.Threatening pests or threatened beneficials? Biting midges are wonderful insects. The animals are so tiny and uniquely shaped that they are particularly good at pollinating the small and tight flowers of the cocoa tree. Without them, there would be much less chocolate. We associate other insects more with the damage that they cause. Mosquitoes and wasps bite us. Moth larvae damage textiles and contaminate foods. Ants undermine our paths and flies are just a pain.But what exactly is our relationship with insects? Are they more beneficial or harmful? What role do they play in the world? What are the effects of climate change: Will the number of insects continue to increase?

    A Guardian 'Readers' Choice' Best Book of 2017Birdsong is woven into our culture, our emotions, our landscape; it is the soundtrack to our world. We have tried to capture this fleeting, ephemeral beauty, and the feelings it inspires, for millennia.In this fascinating account, Richard Smyth asks what it is about birdsong that we so love. Exploring the myriad ways in which it has influenced literature, music, science and our very ideas of what it means to be British, Smyth's nuanced investigation shows that what we hear says as much about us, our dreams and desires, as it does about the birds and their songs.At a time when our birdsong is growing quieter, with fewer voices, more thinly spread, A Sweet, Wild Note is a celebration of the complex relationships between birds, people and the land; it is also a passionate call to arms lest our trees and hedgerows fall silent.

    As one of the largest predators left in Britain, the fox is captivating: a comfortably familiar figure in our country landscapes; an intriguing flash of bright-eyed wildness in our towns.Yet no other animal attracts such controversy, has provoked more column inches or been so ambiguously woven into our culture over centuries, perceived variously as a beautiful animal, a cunning rogue, a vicious pest and a worthy foe. As well as being the most ubiquitous of wild animals, it is also the least understood.In Foxes Unearthed Lucy Jones investigates the truth about foxes in a media landscape that often carries complex agendas. Delving into fact, fiction, folklore and her own family history, Lucy travels the length of Britain to find out first-hand why these animals incite such passionate emotions, revealing our rich and complex relationship with one of our most loved - and most vilified - wild animals. This compelling narrative adds much-needed depth to the debate on foxes, asking what our attitudes towards the red fox say about us - and, ultimately, about our relationship with the natural world.

  • 21st-Century Yokel af Tom Cox E-bog 21st-Century Yokel af Tom Cox

    21st-Century Yokel explores the way we can be tied inescapably to landscape, whether we like it or not, often through our family and our past. It s not quite a nature book, not quite a humour book, not quite a family memoir, not quite folklore, not quite social history, not quite a collection of essays, but a bit of all six.It contains owls, badgers, ponies, beavers, otters, bats, bees, scarecrows, dogs, ghosts, Tom s loud and excitable dad and, yes, even a few cats. It s full of Devon s local folklore the ancient kind, and the everyday kind and provincial places and small things. But what emerges from this focus on the small are themes that are broader and bigger and more definitive.The book s language is colloquial and easy and its eleven chapters are discursive and wide-ranging, rambling even. The feel of the book has a lot in common with the country walks Tom Cox was on when he composed much of it: it s bewitched by fresh air, intrepid in minor ways, haunted by weather and old stories and the spooky edges of the outdoors, restless, sometimes foolish, and prone to a few detours... but it always reaches its intended destination.The book is illustrated with Tom s own landscape photographs and linocuts by his mother.

  • 7 Years of Camera Shake af David Plummer E-bog 7 Years of Camera Shake af David Plummer

    As humans, we are drawn to predators like no other group of animals. They are the epitome of form and function, and have a level of perfection that we revere.In 2009, wildlife expert, conservationist and photographer David Plummer was diagnosed with Parkinson s disease. Rather than let it defeat him, he was galvanised to grab life by the horns and achieve the perfect wildlife shot. Over the next seven years, he did much more than that. The result is this breathtaking collection of over 200 of his best and favourite photographs of exotic and wild animals in their natural habitats. To capture them, David travelled to some of the most remote and stunning locations across the world, from Africa to India to the Gal pagos Islands and back to his native England.7 Years of Camera Shake showcases seven years of immersive and illuminating photography: of predators on the prowl, of prey in the clutches of death, of the inexplicable synchronisation of nature, of the beautiful relationship between mother and child, and much, much more. Plummer s work has been featured in wildlife publications and national and international press, and now the work he has produced since his diagnosis is showcased here, accompanied by his thoughts and anecdotes on how he achieved each perfect shot.

  • Nueces River af Margie Crisp Spar 19% E-bog Nueces River af Margie Crisp

    First appearing on early Spanish maps as the Ro Escondido, or hidden river, and later named Ro de las Nueces after the abundant pecan trees along its banks, the Nueces today is a stream of seeming contradictions: a river that runs above and below ground; a geographic reminder of a history both noble and egregious; and a spring-fed stream transformed into a salty, steep-sided channel. From its fresh, clear headwaters on the Edwards Plateau, Margie Crisp and William B. Montgomery follow the river through the mesquite and prickly pear of the South Texas Plains, to the river's end in Nueces and Corpus Christi Bays on the Gulf of Mexico. With vivid prose and paintings, they record their travels as they explore the length of the river on foot, kayak, and fishing boat, ultimately weaving a vivid portrait of today's Nueces. Capturing the river's subtle beauty, abundant wildlife, diverse culture, and unique history of exploration, conflict, and settlement, they reveal the untold story of this enigmatic river with passion, humor, and reverence.

  • Glorious Gulf of Mexico af Jesse Cancelmo Spar 19% E-bog Glorious Gulf of Mexico af Jesse Cancelmo

    Stunned by widespread ignorance about the Gulf of Mexico following the 2010 Macondo oil spill, underwater photographer Jesse Cancelmo decided to turn his camera on the marine life of this 600,000 square mile international sea that connects five US states, six Mexican states, and the island nation of Cuba. With the goal of countering dismissive descriptions of a Gulf plagued with dead zones and overrun by oil rigs, Cancelmo set out to capture a world rarely acknowledged, let alone seen. Between the Gulfs rich shoreline habitats and its prolific oceanic communities, thriving amid dazzling coral reefs, brine seeps, canyons, salt domes, and hard bottom banks, are more than 15,000 species, including an iconic cast of sea animals: sperm whales, manta rays, whale sharks, manatees, spotted dolphins, and more. Capturing images from locations all around the Gulf, Cancelmo reveals the beauty and glory of these diverse habitats and species. Although this is a book of sensational underwater photography, Cancelmo intends it to be more than a celebration of oceanic beauty. He also hopes to inspire better understanding and appreciation of the natural marine habitats in the Gulf and to strengthen support for their protection and sustainment.

  • Alligators of Texas af Louise Hayes Spar 19% E-bog Alligators of Texas af Louise Hayes

    Found only in the United States, the American alligator ranges in Texas through 120 counties, from the Sabine River to the Rio Grande, across a swath of river drainages and coastal marshes that include both the backwater swamps of the Big Thicket and the urban bayous of greater Houston. From its beginning in a pile of eggs buried in a meticulously constructed nest to its possible end as an alligator burger or a pair of boots, an alligator's habitat preferences sometimes coincide with the favorite haunts of boaters, hunters, and coastal residents. In Alligators of Texas, biologist Louise Hayes and photographer Philippe Henry bring readers up close to this cryptic reptile's food choices, parenting skills, communication techniques, and responses to natural events such as freezes and hurricanes. They also relate some Texas ';alligator tales'; discuss alligator farming, hunting, and live capturing; and examine how people can successfully co-exist with this predator. They end by telling readers where they can view alligators, both in the wild and in captivity. Although not as often, as easily, or perhaps as happily observed as white-tailed deer or armadillos, the American alligator is an iconic Texas animal, and knowing more about its life and habits can help Texans better understand its rightful place in the landscape.

  • Building an Ark for Texas af Walt Davis Spar 19% E-bog Building an Ark for Texas af Walt Davis

    Recounted through the eyes of a major participant, this book tells the story of the Dallas Museum of Natural History from its beginning in 1922 as a collection of specimens celebrating the plants and animals of Texas to its metamorphosis in 2012 as the gleaming Perot Museum of Nature and Science. The life of this museum was indelibly influenced by a colorful staff of scientists, administrators, and teachers, including a German taxidermist, a South American explorer, and a Milwaukee artist, each with a compelling personal investment in this museum and its mission. From the days when meticulously and skillfully prepared dioramas were the hallmark of natural history museums to the era of blockbuster exhibits and interactive education, Walt Davis traces the changing expectations of and demands on museums, both public and private, through an engaging, personal look back at the creation and development of one exceptional institution, whose building and original exhibits are now protected as historical landmarks at Fair Park in Dallas.

  • Texas Riparian Areas Spar 19% E-bog Texas Riparian Areas  

    Riparian areastransitional zones between the aquatic environments of streams, rivers, and lakes and the terrestrial environments on and alongside their banksare special places. They provide almost two hundred thousand miles of connections through which the waters of Texas flow. Keeping the water flowing, in as natural a way as possible, is key to the careful and wise management of the state's water resources.Texas Riparian Areas evolved from a report commissioned by the Texas Water Development Board as Texas faced the reality of over-allocated water resources and long-term if not permanent drought conditions. Its purpose was to summarize the characteristics of riparian areas and to develop a common vocabulary for discussing, studying, and managing them.

  • American Sea af Rezneat Milton Darnell Spar 19% E-bog American Sea af Rezneat Milton Darnell

    For more than a decade, Rezneat Darnell worked on this major synthesis of what is known about the Gulf of Mexico. His goal: to bring a deeper understanding of ';the American Sea' to students, scientists, managers, and educated citizens of the public at large. The American Sea builds on Darnell's own research, the research of his graduate students, government agency research reports, data synthesis reports, and literature summaries to present a holistic view of the Gulf of Mexico. Although he is recognized as a pioneer in the study of continental shelf ecology, Darnell largely resisted specialization, remaining throughout his career ';the writer and bringer together of things.' Here, he has written a book that embraces history, geology, geography, meteorology, chemistry, biology, ecology, and human relations in one comprehensive reference. Although it is thorough and meticulous in coverage, what comes through in these pages is the enormity, complexity, and mystery of the world that lies just beyond the Texas vacation beach, the Louisiana wetland, or the Mexico fishing village. In addition to photographs of deep water and other organisms that are included in the book, a number of illustrations have been added to provide excellent visual material, including historical and ocean floor maps and many works of original art depicting marine species, sea turtles, fish, and crustaceans.

  • Vertical Reefs af Mary Katherine Wicksten Spar 19% E-bog Vertical Reefs af Mary Katherine Wicksten

    On a clear night, the bright lights of oil platforms sparkle in the Gulf of Mexico. Thousands of these platforms off the coasts of Texas and Louisiana play an important role in the lives of underwater species who find food, shelter, and permanent homes in the ecosystem created by these big, three-dimensional structures standing on the flat sea floor. They may also play lesser-known roles ';above the waves' in the migration of birds and even insects. Tapping into years of diving experience, marine biologist Mary Wicksten looks at the inhabitants and visitors of these ';vertical reefs', explaining how life arrives on the platforms, what species settle and stay (like barnacles), and which ones visit then disappear (like silky sharks). She looks at how different life forms take up occupancy from the surface downward, and she shows how these communities vary on nearshore and deepwater platforms. While most people may never experience the undersea world of oil platforms, this book will bring a better understanding of it to any teacher, beachgoer, angler, diver, or coastal resident who ever wondered what was going on beneath those far-off lights.

  • Amphibians and Reptiles of the US-Mexico Border States/Anfibios y reptiles de los estados de la frontera Mexico-Estados Unidos Spar 19% E-bog Amphibians and Reptiles of the US-Mexico Border States/Anfibios y reptiles de los estados de la frontera Mexico-Estados Unidos  

    In the first bilingual work on the reptiles and amphibians of the USMexico border, top herpetologists come together to describe the herpetofauna of the states of this region, which includes more than 600 species of toads, frogs, salamanders, turtles, sea turtles, alligators, lizards, snakes, and sea snakes that are found along the almost 2,000-mile border between the two countries. Each chapter is devoted to one statefour in the US (California, Arizona, New Mexico, and Texas) and six in Mexico (Baja California, Sonora, Chihuahua, Coahuila, Nuevo Leon, and Tamaulipas)with text in both English and Spanish. The chapters contain an introduction to the area, a review of the research, a sketch of the state's physiography, and a description of the species present as well as the pertinent conservation issues they face. A color photo gallery includes images of nearly all species. Almost 40 percent of the featured native species are shared between the US and Mexico, reminding us that animals depend on the integrity of natural landscapes and proving the need for a comprehensive, bilingual reference to help lead a shared effort in the management and conservation of the borderlands.
