"As a follow up to The Natural History of the Snakes and Lizards of Iowa, this book is a combination of general and technical information about each of Iowa's 13 turtle species along with Iowa-specific morphological and reproductive data found nowhere else"--

This book is an in-depth look at the natural history of each snake and lizard species/subspecies found in Iowa. Each of the thirty-three species accounts includes a sampling of the common names the species has been known by in the past, the first specimens collected in the state, and a brief history of the early Iowa literature related to the species, along with a complete description and a discussion of similar species, distribution in the state, habitat, behavior, threats, foods and feeding, and reproduction. While readers will be able to identify Iowa’s snakes and lizards through its species accounts, identification keys, and beautiful photographs and illustrations, this book is intended to be more than a field guide. What makes it truly unique is the comparison of historic data collected by Iowa herpetologists in the 1930s and 1940s with data collected by the author, along with James L. Christiansen and others, since 1960. Custom maps show the reader how species’ distributions have changed over time.

From the hefty alligator snapping turtle—the largest freshwater turtle in North America and the only turtle in the world with a predatory lure in its mouth—to the wood turtle, which uses “worm stomping” to catch earthworms, to the lovely ornate box turtle, which closes its shell completely for self-defense, the slow-but-sure turtle is an intriguing reptile. Terry VanDeWalle provides a complete description of each species, both male and female, along with distinguishing characteristics for fourteen subspecies, information about range and habitat, and natural history notes about behavior, hibernation, diet, and nesting. Two panels devoted to hatchlings provide short descriptions of the young of each species as well as photographs of some commonly seen young turtles.

Covering all facets of the biology of a little-known genus, Peter V. Lindeman’s lavishly illustrated Map Turtle and Sawback Atlas is both a scientific treatise and an engaging introduction to a striking group of turtles. Map turtles and sawbacks, found in and along rivers from Texas to Florida and north to the Great Lakes, fascinate ecologists and evolutionary biologists. Over a short geologic time span, these turtles achieved exceptional biological diversification. Their diets are also exceptionally diverse, and a significant difference in size distinguishes males from females. Adult males are typically half or less the shell length of adult females, making map turtles and sawbacks the champions of sexual dimorphism among not only turtles but all four-legged vertebrates. Aesthetics also draw biologists and hobbyists to map turtles and sawbacks. While the male Sabine map turtle may look to some like a “pencil-necked geek,” as the author puts it, markings on the shell, limbs, head, and neck make map turtles among the most attractive turtles on earth. Sawbacks feature a striking ridge down their shell. Few turtles show themselves off to such advantage. Photographs included here of Graptemys basking poses reveal to what improbable heights these turtles can scale, the spread-eagle sunning stances they adopt, the stacking of individuals on a crowded site, and the heads that warily watch the world above the waterline. In lively prose, Lindeman details the habitat, diet, reproduction and life history, natural history, and population abundance of each species. A section on conservation status summarizes official state, federal, and international designations for each species, along with efforts toward population management and recovery as well as habitat preservation. The author also outlines promising avenues for future research, ranging from the effects of global climate change on populations to strategies for combating expansion of the pet trade.

The Turtles of Mexico is the first comprehensive guide to the biology, ecology, evolution, and distribution of more than fifty freshwater and terrestrial turtle taxa found in Mexico. Legler and Vogt draw on more than fifty years of fieldwork to elucidate the natural history of these species. The volume includes an extensive introduction to turtle anatomy, taxonomy, phylogeny, biogeography, and physiology. A key to the turtles of Mexico is included along with individual species accounts featuring geographic distribution maps and detailed color illustrations. Specific topics discussed for each species include habitat, diet, feeding behavior, reproduction, predators, parasites, growth and ontogeny, sexual dimorphism, growth rings, economic use, conservation, legal protection, and taxonomic studies. This book is a complete reference for scientists, conservationists, and professional and amateur enthusiasts who wish to study Mexican turtles.

Winner, 2011 Book Award, The Wildlife Society2009 Outstanding Academic Title, Choice Ernst and Lovich’s thoroughly revised edition of this classic reference provides the most updated information ever assembled on the natural histories of North American turtles. From diminutive mud turtles to giant alligator snappers, two of North America’s most prominent experts describe the turtles that live in the fresh, brackish, and marine waters north of Mexico. Incorporating the explosion of new scientific information published on turtles over the past fifteen years—including the identification of four new species—Ernst and Lovich supply comprehensive coverage of all fifty-eight species, with discussions of conservation status and recovery efforts. Each species account contains information on identification, genetics, fossil record, distribution, geographic variation, habitat, behavior, reproduction, biology, growth and longevity, food habits, populations, predators, and conservation status. The book includes range maps for freshwater and terrestrial species, a glossary of scientific names, an extensive bibliography for further research, and an index to scientific and common names. Logically organized and richly illustrated—with more than two hundred color photographs and fifty-two maps—Turtles of the United States and Canada remains the standard for libraries, museums, nature centers, field biologists, and professional and amateur herpetologists alike.
