Book Description
In this study the author analyzes the phylogenetic relationships among the genera and species of alligator lizards (Squamata: Anguidae: Gerrhonotinae). The subfamily consists of six monophyletic genera: Coloptychon, Gerrhonotus, Elgaria, Barisia, Mesaspis, and Abronia. The author reviews the history of gerrhonotine taxonomy, provides a key to, and diagnoses of, all gerrhonotine taxa, and discusses taxonomic and biogeographic implications of gerrhonotine relationships.

Book Description
With its varied topography of coast, mountains, and desert, the San Diego region, considered one of the world’s biodiversity hotspots, boasts a rich variety of amphibians and reptiles—from the arboreal salamander to the green sea turtle to the secretive San Diego banded gecko and the red diamond rattlesnake. More than a field guide, this up-to-date, authoritative, conservation-oriented book is the first comprehensive resource on the herpetofauna of the region, which is unfortunately also known for its high number of endangered species. Jeffrey M. Lemm gives information on identification, habitats, biology, and the conservation status of all 88 amphibian and reptile species found in the San Diego region. Many of these animals can also be found in a wide area of Southern California and Northern Baja California, making this valuable guide useful for a wide geographic area and a must-have for outdoor enthusiasts, nature-lovers, and professionals alike. * Includes a special venom section written by Sean Bush of Animal Planet’s "Venom ER" * 160 color photographs illustrate the major habitats and all 88 amphibians and reptiles found in the region * 70 range maps pinpoint the locations of each subspecies * A new, easy-to-use taxonomic key by renowned herpetologist Jay Savage as well as line drawings of tadpoles and amphibian egg masses help make species identification simple

Book Description
Key features: Presents a contemporary snapshot of the mechanisms underlying the evolution and adaptation of behavior Explores how genetics, epigenetics, development, and environment shape behavior Discusses a broad range of behavioral repertoires and responses, including those related to thermoregulatory, foraging, predatory, displaying, social and escape strategies. Examines physiological and sensory mechanisms Covers the effects of various aspects of global change on behavior, with chapters that focus on the impacts of climate change on hydroregulatory behavior and behavioral responses to the effects of habitat alteration resulting from human-mediated change and colonization by invasive species. Lizards serve as focal organisms for many of biological questions related to evolution, ecology, physiology, and morphology. They are studied at multiple spatial and temporal scales, from the individual to the community level. This book, authored by expert contributors from around the world, explores behaviors underlying the evolution and adaptation of these organisms. It covers conceptual, empirical, and methodological approaches to the understanding of the role that natural and sexual selection play in molding the behavioral traits of lizards. This thorough, illustrated reference should stimulate discussion of the conceptual and methodological approaches for studying the behavioral traits of these fascinating and highly diverse vertebrates.

Book Description
In the first bilingual work on the reptiles and amphibians of the US–Mexico border, top herpetologists come together to describe the herpetofauna of the states of this region, which includes more than 600 species of toads, frogs, salamanders, turtles, sea turtles, alligators, lizards, snakes, and sea snakes that are found along the almost 2,000-mile border between the two countries. Each chapter is devoted to one state—four in the US (California, Arizona, New Mexico, and Texas) and six in Mexico (Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, and Tamaulipas)—with text in both English and Spanish. The chapters contain an introduction to the area, a review of the research, a sketch of the state’s physiography, and a description of the species present as well as the pertinent conservation issues they face. A color photo gallery includes images of nearly all species. Almost 40 percent of the featured native species are shared between the US and Mexico, reminding us that animals depend on the integrity of natural landscapes and proving the need for a comprehensive, bilingual reference to help lead a shared effort in the management and conservation of the borderlands.

Book Description
To determine the mechanisms for species-spacing in a group of closely related bird species--namely, five species of Neotropical Kingfishers--the author studied their feeding behavior and diet at three sites, two in Bolivia and one in Colombia. He found that changes in number of coexisting species were correlated with changes in abundance and size distribution of their prey, surface-dwelling fishes.

Book Description
IN THIS REVISED edition of Amphibians and Reptiles of Texas, James R. Dixon adds to and updates the extensive information given in the first edition. A new section on conservation issues highlights some of the problems facing the continued survival of amphibians and reptiles, particularly commercial collecting and habitat destruction. Taxonomic changes have been made to reflect the latest scientific information, and the extensive listing of the literature on Texas amphibians and reptiles has been updated through April, 1999. Going back to the writings of French botanist Jean Louis Berlandier, who encountered Texas herpetofauna during his travels from 1828 to 1834, this list covers more than 150 years of inquiry into the state's species and is also testimony to the distinguished careers of such herpetologists as Hobart M. Smith and, more recently, Chris McAllister. Another prominent feature of this book is the more than 150 distribution maps, which show by county the updated distribution records for all native Texas amphibians and reptiles, based on more than 13,000 county records and more than 110,000 individual localities. Professional and amateur herpetologists as well as environmentalists, wildlife specialists, campers, and hikers will find the dichotomous keys useful for identifying species at hand. This aid to identification is supported by a glossary, drawings and photographs, and complete scientific and common names.

Book Description
In this study the author describes Hypsibarbus, a new genus of Asian cyprinid fishes with twelve species, three of them new. A complete set of 45 measurements and 17 counts was taken and analyzed for approximately 250 specimens, including all type material, of more than 1000 specimens encountered, representing most of the major fish collections of the world. The author fully redescribes and illustrates all species in the new genus, and includes keys for their identification. To provide a basis for understanding zoogeographic implications of the phylogeny obtained for Hypsibarbus, the geography and history of the Southeast Asia river basins is discussed in detail.
