Book Description
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.

Book Description
This book grew from a series of lectures on vertebrate natural history. The topics have been developed over a period of nearly 30 years, and today scarcely resemble the original subject matter. The progress is primarily technical. Some concepts provide a synthetic framework for viewing much modern research, but many of these concepts either date from Darwin or have developed from obser vations of later students. Animal science courses follow a sequential pattern in which there are three discrete levels of undergraduate instruction. Initially, students study subject mat ter contained in such courses as biology and general zoology. These courses intro duce students to animal phylogeny, basic plans of morphology and certain phys iological aspects; incidental to these subjects the student acquires a broad zoological vocabulary. At the other end of the academic spectrum are courses that emphasize synthe sis and theory: evolution, zoogeography, behavior and ecology are important courses whose role is to explore the relationships of various aspects of the physical and biological world. In these courses theory and analysis prevail. They are not, however, essentially "subject matter" courses with distinct bodies of knowledge.
