Book excerpt: Today there are 6,800 reptile species on earth; the major groups are alligators and crocodiles, turtles, lizards, and snakes. Reptiles are tetrapods and amniotes, animals whose embryos are surrounded by an amniotic membrane. Today they are represented by four surviving orders: crocodilia (crocodiles, caimans and alligators), sphenodontia (tuataras from New Zealand, squamata (lizards, snakes and amphisbaenids - "worm-lizards"), and testudines (turtles).

Download or read book Dermal Absorption Models in Toxicology and Pharmacology written by Jim E. Riviere and published by CRC Press. This book was released on 2005-08-24 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many experimental methods and mathematical modeling approaches rooted in disciplines outside of toxicology can be effectively applied to estimating dermal absorption. Dermal Absorption Models in Toxicology and Pharmacology explores current approaches and techniques that can be used to quantify dermal absorption with endpoints useful in both toxicology and pharmacology. The book begins with a review of basic principles and the in vitro and in vivo experimental approaches available for assessing dermal absorption of drugs and chemicals. This is followed by coverage of mathematical or in silico models for quantitating percutaneous absorption and the applications of these techniques to the risk assessment process. The remainder of the book explores scenarios where the unique properties of the chemicals being studied or the matrix in which they are exposed must be considered and then wraps up with a comparative analysis of chemical permeability in human and animal skin. Many of the books covering this subject are just too comprehensive and serve primarily as reference works. This book takes a different approach. Jim Riviere's editorial guidance ensures that the information is readable, accessible, authoritative, and concise, making it the perfect resource for familiarizing new researchers and students to the field and updating established scientists.

Download or read book Herpetological Osteopathology written by Bruce M. Rothschild and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.

Available in PDF, EPUB and Kindle. Book excerpt: "This volume includes detailed accounts of the morphology and distribution of the fossil snakes of North America and also remarks on their evolutionary, zoogeographic, and paleoecological patterns. The heart of the book consists of detailed systematic accounts of the known fossil snakes of North America and their localities. Extinct fossil taxa are discussed and illustrated, and many are re-described on the basis of new information. The book provides illustrations of diagnostic vertebrae and criteria for the identification of presently living fossil snake taxa as well as descriptions of the modern characteristics and ranges of these species." "Color photographs in the 16-page insert present a catalog of representative living snake species." --Book Jacket.

Book excerpt: Snakes of the World: A Catalogue of Living and Extinct Species—the first catalogue of its kind—covers all living and fossil snakes described between 1758 and 2012, comprising 3,509 living and 274 extinct species allocated to 539 living and 112 extinct genera. Also included are 54 genera and 302 species that are dubious or invalid, resulting in recognition of 705 genera and 4,085 species. Features: Alphabetical listings by genus and species Individual accounts for each genus and species Detailed data on type specimens and type localities All subspecies, synonyms, and proposed snake names Distribution of species by country, province, and elevation Distribution of fossils by country and geological periods Major taxonomic references for each genus and species Appendix with major references for each country Complete bibliography of all references cited in text and appendix Index of 12,500 primary snake names The data on type specimens includes museum and catalog number, length and sex, and collector and date. The listed type localities include restrictions and corrections. The bibliography provides complete citations of all references cited in the text and appendix, and taxonomic comments are given in the remarks sections. This standard reference supplies a scientific, academic, and professional treatment of snakes—appealing to conservationists and herpetologists as well as zoologists, naturalists, hobbyists, researchers, and teachers.

Download or read book Naturalized Reptiles and Amphibians of the World written by Christopher Lever and published by . This book was released on 2003 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency--either accidentally or deliberately--and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by and independent of mankind.

Download or read book Pleistocene Amphibians and Reptiles in Britain and Europe written by J. Alan Holman and published by Oxford University Press. This book was released on 1998-06-18 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pleistocene epoch or Ice Age, an extended period of advancing and retreating ice sheets, is characterized by striking climatic oscillations and sea level fluctuations. This age saw the rise and spread of humans and a great extinction of large mammals by the end of the epoch; in fact, the world today is essentially the product of dramatic changes that took place in the Pleistocene. This book, a companion to the author's Pleistocene Amphibians and Reptiles in North America, discusses the Pleistocene amphibians and reptiles in Britain and the European continent eastward through present-day Poland, the Czech Republic, Hungary, the Yugoslavian republics, and Greece. The book begins with a general discussion of the Pleistocene in Britain and Europe with an emphasis on regional terms used to define Pleistocene chronological events. Next, a look at the pre-Pleistocene herpetofauna of the study area sets the stage for a discussion of Pleistocene herpetofauna. A significant section of the book consists of a "bestiary," a series of annotated taxonomic accounts of Pleistocene herpetological taxa from the region. Following this is the interpretive section, beginning with a discussion of herpetological species as paleoenvironmental indicators and continuing with an analysis of herpetological population adjustments to Pleistocene events in Britain and Europe, and then with a discussion of extinction patterns in the region. Finally, the author compares Pleistocene herpetological events in Europe with those in North America. This volume and its companion together provide an up-to-date and comprehensive review of Pleistocene herpetofaunas across a significant portion of the Northern Hemisphere.
