The small, terrestrial eastern red-backed salamander is abundant on many forest floors of northeastern North America. Dr. Robert Jaeger and many of his graduate students spent over 50 years studying this species in New York and Virginia, using ecological techniques in forests and behavioral experiments in laboratory chambers in an attempt to understand how this species interacts with other species in the forest and the components of its intra- and intersexual social behaviors.The competitive and social behaviors of this species are unusually complex for an amphibian. This species is highly aggressive towards other similar-size species where they cohabit in forests, often leading to very little geographic overlap between the species. The authors examine the fascinating behavioral traits of this species including social monogamy, mutual mate guarding, sexual coercion, inter-species communication, and conflict resolution.

Offering a state-of-the-art overview of plethodontid salamanders, this text provides an understanding of many aspects of the evolution, systematics, development, morphology, life history, ecology, and field methodology of these animals. The book is divided into three sections. The first one features papers presented in honour of Richard Highton, a specialist in molecular systematics and speciation in plethodontids. This section, therefore, deals with amphibian systematics. The second section presents topics in evolutionary and comparative biology of plethodontids, and thus reflects the diversity of research on plethodontid salamanders. Finally, the third section presents topics in behavioural ecology of small Plethodon (mainly P. cinereus), illustrating the usefulness of the smaller species of Plethodon as model organisms for investigation of a wide range of questions in behavioural ecology.

The fourth Conference on the Biology of Plethodontid Salamanders was held at "The Mountain," in Highlands, North Carolina on June 12-14, 1998. Hosted by the Highlands Biological Station, and sponsored by the Highlands Biological Foundation, Inc. , the conference afforded a state-of-the-art overview of these animals, as evidenced by the contents of the present volume and the credentials of the contributors. In the following pages, the reader will find the best current understanding of many aspects of plethodontid salamander evolution, systematics, development, morphology, life history, ecology, and field methodology. While the contents of this book consist of chapters developed from selected conference papers, their excellence is representative of the high overall quality of the conference presentations. The Highlands Biological Station is located on the Highlands Plateau in the southern Blue Ridge Mountains. As these mountains are a present center of plethod ontid diversity, and are considered by some to be the center of origin of the group, the Highlands Biological Station has historically been important in the study of these animals. A list of visitors to the Station for the last 70 years would include a "who's who" of twentieth century North American herpetologists. The location and amenities of the Highlands Biological Station are unique. Within the city limits of Highlands at an elevation of nearly 1200 meters, the Station includes modern research laboratories, administrative offices, library facilities, as well as dormitory and living facilities.
