In essays that survey the burgeoning field of tropical herpetology, former students and associates pay tribute to Jay Savage's four decades of mentoring. The result is a book unlike any other available in tropical herpetology. Covering a wide array of subjects, this is the first book in more than two decades to broadly review research on tropical amphibians and reptiles. A tribute to Savage and an invaluable addition to herpetological literature, it will be cited for years to come.

From tiny, burrowing lizards to rainforest canopy-dwellers and giant crocodiles, reptile populations everywhere are changing. Yet government and conservation groups are often forced to make important decisions about reptile conservation and management based on inadequate or incomplete data. With contributions from nearly seventy specialists, this volume offers a comprehensive guide to the best methods for carrying out standardized quantitative and qualitative surveys of reptiles, while maximizing comparability of data between sites, across habitats and taxa, and over time. The contributors discuss each method, provide detailed protocols for its implementation, and suggest ways to analyze the data, making this volume an essential resource for monitoring and inventorying reptile abundance, population status, and biodiversity. "Reptile Biodiversity" covers topics including: terrestrial, marine, and aquatic reptiles; equipment recommendations and limitations; ethics of monitoring and inventory activities; statistical procedures; designing sampling programs; and, using PDAs in the field.

For nearly 200 million years, Earth has been occupied by reptiles—a lineage of terrestrial vertebrates that includes some, like birds, that have invaded the aerial environment, and others, like turtles, that have invaded aquatic environments. With thirty-nine known species, Alabama harbors more turtle species than any other state in the nation, and its Mobile River basin is the center of the world's greatest biodiversity in turtles, surpassing all other river systems around the globe, including the Amazon and the Nile. Turtles of Alabama documents that extraordinary wealth and presents each species in full, describing its physical appearance, habitat and range, behavior, conservation and management, and taxonomy.In addition to providing sixty-five full-color photographs of juveniles and adults along with forty-two colorfully detailed distribution maps, this volume features an introductory section explaining the physiography, climate, and habitats of the state, and offers illustrated taxonomic keys for all the species considered, including the oceanic behemoths that lay their eggs on Alabama's gulf beaches and the lumbering gopher tortoise that provides safe haven for countless other animals and arthropods in its underground burrows of the Coastal Plain. With fine line drawings to highlight various distinguishing attributes of the animals, this volume is the definitive guide to the state’s fascinating and diverse turtle populations—freshwater, marine, and terrestrial.Although they are notoriously slow-moving, turtles still survive on Earth because of their remarkable adaptations—an exterior shell for body protection, long lives, high reproductive output, stamina, and a capacity for doing without. Turtles are cold-blooded reptiles that were here long before mammals, and they're still around, continuing to adapt to many different habitats and ecological niches, still interbreeding, evolving, and speciating. Turtles of Alabama is a fitting celebration of that phenomenal variety and strength.

An up-to-date and comprehensive herpetological guide to Alabama. Lizards and Snakes of Alabama is the most comprehensive taxonomy gathered since Robert H. Mount's seminal 1975 volume on the reptiles and amphibians of Alabama. This richly illustrated guide provides an up-to-date summary of the taxonomy and life history of lizards and snakes native to, or introduced to, the state. Alabama possesses one of the most species-rich biotas in north temperate areas and this richness is reflected in some groups of lizards, such as skinks, and especially in snakes. The authors examine all known species within the state and describe important regional variations in each species, including changes in species across the many habitats that comprise the state. Significant field studies, especially of Alabama's threatened and endangered species, have been performed and are used to inform discussion of each account. The life-history entry for each species is comprised of scientific and common names, full-color photographs, a morphological description, discussion of habits and life cycle, and a distribution map depicting the species range throughout the state, as well as notes on conservation and management practices. The illustrated taxonomic keys provided for families, genera, species, and subspecies are of particular value to herpetologists. This extensive guide will serve as a single resource for understanding the rich natural history of Alabama by shedding light on an important component of that biodiversity. Accessible to all, this volume is valuable to both the professional herpetologist and the general reader interested in snakes and lizards.
