Book Description
This guide brings together, for the first time in single volume, a comprehensive review of all the world's pheasants, partridges, quails, grouse, turkeys, guineafowl, buttonquails, sandgrouse, and the enigmatic Plains-wanderer - over 250 species in all. The group includes some of the world's most familiar and beautiful birds, such as Indian Peafowl and the stunning tragopans, as well as some of the rarest and most threatened. Some survive in fragments of over-exploited habitats, whilst others are now so familiar in domestication that it is difficult to imagine that they had any wild ancestors at all. As with other volumes in the award-winning Helm Identification Guide series, this book concentrates on identification and distribution, but also highlights conversation issues where relevant. Each species is treated in detail, reflecting the extensive knowledge of both authors. The 72 colour plates, by leading bird illustrators, show male, female, juvenile and subspecies plumages, and form the finest set of illustrations of these birds to date. There is also a colour distribution map for each species. Pheasants, Partridges & Grouse is a welcome addition to the Helm Identification Guide series, more importantly, a landmark volume in the literature of this attractive and vulnerable group of birds.

Book Description
The American South is famous for its astonishingly rich biodiversity. In this book, Georgann Eubanks takes a wondrous trek from Alabama to North Carolina to search out native plants that are endangered and wavering on the edge of erasure. Even as she reveals the intricate beauty and biology of the South's plant life, she also shows how local development and global climate change are threatening many species, some of which have been graduated to the federal list of endangered species. Why should we care, Eubanks asks, about North Carolina's Yadkin River goldenrod, found only in one place on earth? Or the Alabama canebrake pitcher plant, a carnivorous marvel being decimated by criminal poaching and a booming black market? These plants, she argues, are important not only to the natural environment but also to southern identity, and she finds her inspiration in talking with the heroes the botanists, advocates, and conservationists young and old on a quest to save these green gifts of the South for future generations. These passionate plant lovers caution all of us not to take for granted the sensitive ecosystems that contribute to the region's long-standing appeal, beauty, and character.

Book Description
This book presents the results and conclusions of the longest continuous study ever undertaken for a local North American game bird population. Since 1950 abundance has been determined seasonally by direct count, nesting ecology by field searches and observation, and hunting pressure and harvest by field interviews. Land use and weather conditions also have been recorded. The period of the study saw considerable change in regional land use and included several of the most severe winters in recorded weather history. Continuing harvest of the study population did not have a progressively depressing effect on standing densities; rather it held breeding stock somewhat below K at a more productive point on the growth curve. Roseberry and Klimstra report that there was clear evidence of an 8 to 10-year cycle within the study population. They found after examining a number of cycle theories that a close temporal relationship existed between their bobwhite data and the nodal lunar cycle described by Archibald (1977). Sound field techniques, long-term data acquisition, and appropriate mathematical and statistical treatment of the data combine to provide a significant contribution to what is known of not only bobwhite but basic population ecology.
