Reptile Biodiversity

Edited by Roy W. McDiarmid, Mercedes S. Foster, Craig Guyer, J. Whitfield Gibbons, and Neil Chernoff

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

Amphibians of Tennessee

Edited by Matthew Niemiller and R. Graham Reynolds

Brimming with color photographs and reflecting the latest scientific research, this book is the definitive guide to the rich diversity of frogs and salamanders found throughout Tennessee. Featuring detailed accounts of all eighty of the state’s species of amphibians, it will delight and inform the professional scientist and amateur naturalist alike.

The species accounts form the core of the book. Each account includes the scientific and common name of the species (with etymology of the scientific name); information on size, physical appearance, and coloration of adults, juveniles, and larvae; an up-to-date GIS range map showing both county records and potential ranges; and details on similar species, habitat, natural history, conservation status, and more. High-quality photographs illustrate the life stages of the various species.

Among the book’s other valuable features are detailed drawings and taxonomic keys to assist with identification, as well as introductory chapters that encompass amphibian biology and conservation and the geology and habitats of Tennessee. Sprinkled throughout the book are lively personal accounts, called “Field Notes,” which describe successful amphibian hunts.

The only complete work of its kind for the Volunteer State and generously supported by the Tennessee Wildlife Resources Agency, The Amphibians of Tennessee fills a long-standing need for both a popular identification guide and an authoritative reference.

Venomous Reptiles of the United States and Canada

By Carl H. Ernst and Evelyn M. Ernst

Carl and Evelyn Ernst have completely revised their landmark referenceVenomous Reptiles of North America to present the most comprehensive review of these animals in years. 

Venomous Reptiles of the United States, Canada, and Northern Mexicorepresents the latest research on these animals and includes the most extensive bibliography of literature on the subject. Anyone with an interest in venom, snakes, or herpetology in general will find a wealth of information within the pages of these impressive volumes.

Volume 1: Heloderma, Micruroides, Micurus, Pelamis, Agkistrodon, Sistrurus

Volume One of this definitive work presents dramatically improved species accounts of the venomous lizards and elapid and viperid snakes found north of Mexico's twenty-fifth parallel. Volume Two will cover the twenty-one rattlesnakes found in the United States, Canada, and, for the first time, species found only in northern Mexico. 

Volume 2: Crotalus

Volume 2 of this definitive work covers the twenty-one species of the genus Crotalus found in the United States, Canada, and, for the first time, those found in northern Mexico. 

Mixing their own research with careful data description and intriguing stories, Ernst and Ernst present the most accurate and interesting view of North America's rattlesnakes available. They provide general background information on Crotalus, including venom delivery systems, how rattles function, what rattlesnakes eat, and what eats rattlesnakes. Additionally, they offer specific and fascinating details, such as observations of rattlesnakes swimming to offshore islands, accounts of male combat bouts, possible "anting" behavior in Crotalus viridis, and the features of the Santa Catalina Island rattleless rattlesnake. Each species account includes vivid photographs, range maps, and explanations of the limits to their respective distribution.

The book begins with a preface describing the status of living tortoises. Despite the dire descriptions, the author emphasizes that there is still hope for the long term survival of most tortoise species. The first couple of chapters define tortoises and discuss the variety of their biology and natural history. The third chapter outlines many of the threats to tortoises, such as habitat destruction, disease, and incidental killing (e.g., road kill). All along the way the author offers good examples using a variety of tortoise species and situations. The fourth chapter, entitled, "Eating Tortoises" was quite enlightening for me. I had no idea what a huge, world-wide problem the consumption of turtles is, or how massive the effect of consumption is on global tortoise populations. Giant tortoises that live on islands are the subject of chapter 5, with both the causes of their decline as well as their conservation discussed in detail. Finally, the problem of captive tortoises is discussed in chapter 6. From the desire to have the really rare tortoise to the seemingly benign desire to simply have any pet tortoise, the author covers a wide variety of issues associated with the captive trade in tortoises and its effect on wild populations. Chapter 7 offers potential solutions by highlighting some successful conservation strategies. This is followed by a final chapter of hope that people will change their ways to protect tortoises. The author also includes some useful appendices: extremes of the tortoise world; tortoises on the brink of extinction; tortoise species; and further reading.

Overall I found this book interesting and informative. I am not well versed with most of the species the author discusses, but I was working on Desert Tortoises in 1988-1989 when the western Mojave populations were emergency listed by the Fish and Wildlife Service. Here I found a couple of minor errors in the book. The author indicated that captive desert tortoises were released into the wild as a result of the emergency listing: "When tortoise owners learned that the pets they had taken from the wild years earlier were now on the endangered species list, many responded in the best-intended way possible. They put the tortoise in the car, drove him back out to the desert, and released him with a sense of having done something good in the world.... Within a few years of the initial listing of desert tortoises as threatened, biologists began to find wild tortoises that were sick."

In fact, upper respiratory disease syndrome was one of the major factors in getting the species listed, not a result of the listing. Personally, I think it is hopeful to think many people would take the time to drive back out to the desert to release their captive tortoise. I am sure it happened, both before and after the species was listed as threatened, but I am somewhat dubious that the listing had much effect on the number of tortoises released.
