This review of Pennsylvania's conservation efforts is the first book to focus exclusively on the state's vertebrates of concern. The 133 species of reptiles, amphibians, birds, and mammals discussed in this book are Pennsylvania's most vulnerable terrestrial vertebrates. Each species is described in a full account that details basic biology and includes photographs and range maps. The accompanying narratives focus on conservation priorities, research needs, and management recommendations. Featuring information compiled from a broad array of sources and by contributors who are recognized authorities on their respective species, this volume is a model for wildlife conservation across much of the northeastern United States. A road map that reveals the Keystone State's most sensitive species and what can be done to manage and conserve these important natural resources, Terrestrial Vertebrates of Pennsylvania is a valuable tool for wildlife managers, conservationists, and naturalists.

"Squirrels of the World", written by scientists with more than 100 years of collective experience studying these popular mammals, is the first comprehensive examination of all 285 species of squirrels worldwide. The authors reveal virtually every detail of the family Sciuridae, which includes ground squirrels, tree squirrels, flying squirrels, prairie dogs, and chipmunks. Each species-from the familiar gray squirrel of American backyards to the exotic and endangered woolly flying squirrel of Pakistan-is described in a detailed account that includes distinguishing characteristics, ecology, natural history, conservation status, and current threats to its existence. "Squirrels of the World" includes: stunning color photographs that document rare and unusual squirrels as well as common varieties; evolution, morphology, ecology, and conservation status; colorful range maps marking species distribution; images of the skull of each genus of squirrel; and extensive references.
