Book Description
A collection of essays on nature, naturalists, and the natural history of fishes in central Appalachia. A nature lover’s paradise, central Appalachia supports a diversity of life in an extensive network of waterways and is home to a dazzling array of fish species. This book focuses not only on the fishes of central Appalachia but also on the fascinating things these fishes do in their natural habitats. An ecological dance unfolds from a species and population perspective, although the influence of the community and the ecosystem also figures in the text. Stuart A. Welsh’s essays link central Appalachian fishes with the complexities of competition and predation, species conservation, parasitic infections, climate change, public attitudes, reproductive and foraging ecology, unique morphology, habitat use, and nonnative species. The book addresses a selection of the families of central Appalachian fishes, including lampreys, gars, freshwater eels, pikes, minnows, suckers, catfishes, trouts, trout-perches, sculpins, sunfishes, and perches. These essays often refer to the works of naturalists who contributed to our knowledge of nature during previous centuries and who recorded their discoveries when science writing was less concise than it is today. Although many of these works are nearly forgotten, these early naturalists built a strong knowledge base that supports much of our current science and thus merits reexamination. Most people are not scientists, but many have an interest in nature and are, in their own way, naturalists. This book is for those people willing to peer beneath the water’s surface.

Book Description
The darters are a fascinating group of colorful and diminutive freshwater fish whose beauty rivals that of the tropical reef fishes. Native only to North America, the darters occur widely, especially in the United States, but are little known to the general public, largely because of their small size—few exceed six inches and some measure a mere one inch at maturity. This book is the first comprehensive guide to the darters, covering all named and several undescribed forms—140 species in all. Each species account includes a synoptic description to aid in separation of similar species and subspecies, a range map, and discussion of the species' distribution, natural heritage, abundance, and scientific name. An illustrated key and glossary will further assist scientists, students, fishermen, and aquarium specialists in identifying darter species. Central to this volume is the series of 144 handsome color photographs illustrating nearly all known darter species and several subspecies. Most of the specimens shown were caught by the authors at sites throughout the United States, Canada, and Mexico, and photographed by them on site using a recently developed technique that captures the full brilliance of the living fish. Because of their importance as indicators of environmental quality, the darters are receiving increasing attention today from scientists and naturalists. Public interest was focused recently on the plight of the snail darter, but many other darter species are either threatened or endangered, and others face an uncertain future as human activities continue to degrade our waterways. All those with an interest in preserving the natural heritage of our rivers and streams will find this comprehensive guide to the darters an invaluable tool.

Book Description
With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Book Description
The Unicoi Mountains straddle the Tennessee-North Carolina state line just south of the Great Smoky Mountains, separated from the latter mountains only by the Little Tennessee River. Extending from the Little Tennessee River southward to the Hiwassee River, the Unicois are a southern segment of the high Unaka ridge that forms the western escarpment of the southern Appalachians. The Snowbird Mountains are included with the Unicois because they are connected like a spur ridge to the Unicois. The Unicois have been isolated and difficult to access until the completion in 1996 of the forty-two-mile-long, superbly scenic Cherohala Skyway that courses along the highest ridges of the Unicois at elevations up to 5,390 feet and provides outstanding views of forested mountains. The Unicoi Mountains have been relatively undisturbed by human development since most of the land is publicly owned and managed by the U.S. Forest Service. The Unicois harbor many diverse natural treasures that are hidden from the casual observer. Along with his personal observations, the author describes and synthesizes the results of scientific research on the natural assets of the Unicois, including intensive surveys of plants and animals in certain areas, the results of which have often been reported only in places where the general public cannot easily access them. The authors purpose in writing the book is to share with others what he has learned about the special natural features (landscape, geology, climate, flora, fungi, and fauna) of the Unicois and their historical rootswith the hope of inspiring others to enjoy, cherish, and conserve them. Unicoi Unity also reviews the history of the effects of humans on the Unicoi ecosystem and anticipates future challenges.

Book Description
"The Encyclopedia details subjects traditionally associated with Appalachia - folklore, handcrafts, mountain music, food, and coal mining - but goes far beyond regional stereotypes to treat such wide-ranging topics as the aerospace industry, Native American foodways, ethnic diversity in the coalfields, education reform, linguistic variation, and the contested notion of what it means to be Appalachian, both inside and outside the region." "Researched and developed by the Center for Appalachian Studies and Services at East Tennessee State University, this 1,864-page compendium includes all thirteen states that constitute the northern, central, and southern subregions of Appalachia - from New York to Mississippi. With entries on everything from Adventists to zinc mining, the Encyclopedia of Appalachia is a one-stop guide to all things Appalachian."--BOOK JACKET.

Book Description
“A lavishly photographed dreambook of the world’s top angling spots” (Men’s Journal) Amateur or expert, every angler dreams of landing “the big one,” but that’s only part of the appeal of fly fishing. Because even when hours pass without a bite, nothing beats the rugged beauty of the surroundings. For both armchair travelers and avid outdoorsmen who may have already started a checklist of their own, Fifty Places to Fly Fish Before You Die maps out the meccas of the fly-fishing world. Through in-depth interviews with the sport’s acknowledged gurus, author Chris Santella goes beyond standard guides to convey the very essence of the recommended locations. Readers can vicariously cast mouse patterns to fifty-pound taimen in the wilds of Mongolia, wrangle with wily permit off the Florida Keys, and match the hatch on Montana’s Armstrong’s Spring Creek. Jardines de la Reina, Cuba (tarpon), the Zhupanova River, Kamchatka (rainbow trout), and the Rio Negro, Brazil (peacock bass) are also included. The fifty essays include a cultural and natural history of each site, along with colorful anecdotes based on the author's and authorities’ experiences. With breath-takingly-beautiful photos of the spots, many by celebrated fly-fishing photographer R. Valentine Atkinson, the book also provides adventurous anglers with enough travel-and-tackle information so that they, too, can start planning excursions to go fish around the globe. Praise for Fifty Places to Fly Fish Before You Die “Santella offers 50 short takes on the ultimate fly-fishing destinations in this beautifully photographed and nicely packaged volume . . . With its elegant descriptions, gorgeous photos and practical information, this book is a dream travel guide for avid fly-fishers.” —Publishers Weekly “Everything dad needs to tackle his next trip.” —Fort Worth Star-Telegram
