Amphibian Declines by Michael Lannoo Pdf

This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.

Owls of the World by Claus König,Friedhelm Weick,Jan-Hendrik Becking Pdf

The definitive book on owls. Owls are enduringly popular birds, but due to their nocturnal habits most species are difficult to see well. The plumages of many species are cryptic and difficult to separate by plumage alone. This problem is compounded by the different morphs that many adopt. This book fully describes every known species and subspecies of owl, as well as presenting the latest evidence on owl taxonomy, based on DNA work and vocalisations. Because voice is vital in owl identification, much emphasis is placed on it in the book and sonograms are provided for many species. A CD of owl vocalisations accompanies the book.

A Passion for Birds by Mark V. Barrow, Jr. Pdf

In the decades following the Civil War--as industrialization, urbanization, and economic expansion increasingly reshaped the landscape--many Americans began seeking adventure and aesthetic gratification through avian pursuits. By the turn of the century, hundreds of thousands of middle-and upper-class devotees were rushing to join Audubon societies, purchase field guides, and keep records of the species they encountered in the wild. Mark Barrow vividly reconstructs this story not only through the experiences of birdwatchers, collectors, conservationists, and taxidermists, but also through those of a relatively new breed of bird enthusiast: the technically oriented ornithologist. In exploring how ornithologists struggled to forge a discipline and profession amidst an explosion of popular interest in natural history, A Passion for Birds provides the first book-length history of American ornithology from the death of John James Audubon to the Second World War. Barrow shows how efforts to form a scientific community distinct from popular birders met with only partial success. The founding of the American Ornithologists' Union in 1883 and the subsequent expansion of formal educational and employment opportunities in ornithology marked important milestones in this campaign. Yet by the middle of the twentieth century, when ornithology had finally achieved the status of a modern profession, its practitioners remained dependent on the services of birdwatchers and other amateur enthusiasts. Environmental issues also loom large in Barrow's account as he traces areas of both cooperation and conflict between ornithologists and wildlife conservationists. Recounting a colorful story based on the interactions among a wide variety of bird-lovers, this book will interest historians of science, environmental historians, ornithologists, birdwatchers, and anyone curious about the historical roots of today's birding boom.
