Available in PDF, EPUB and Kindle. Book excerpt: In this definitive work, Ernest Glen Wever establishes the evolutionary importance of the reptile ear as the origin of the higher type of auditory apparatus shared by man and the mammals. Tracing the development of the auditory receptor in the living reptiles, he examines the use of a variety of mechanisms and principles of action by that receptor. While some of the material in this book has appeared previously in journal articles, most of it is presented here for the first time. Basing this study on his twenty years of research at Princeton's Auditory Research Laboratories, Professor Wever treats in anatomical and functional detail the auditory mechanism in about 250 species and subspecies of reptiles. The anatomical treatment rests on dissections and histological examinations of the ears in serial section, and portrays the relevant features in drawings that represent particular views of reconstructions. The author evaluates the performance of thesse ears electrophysiologically, in terms of the electrical potentials of the cochlea, paying particular attention to problems of the transmission of vibrations inward to the cochlea and the actions there in stimulating the sensory cells. Professor Wever finds that the cochlea emerged independently from the non-auditory labyrinth in three different vertebrate groups: fishes, amphibians, and reptiles. It was among the reptiles, however, that the vertebrate ear took on a more advanced configuration from which it further evolved along separate lineages in the birds and mammals. Ernest Glen Wever is Eugene Higgins Professor of Psychology Emeritus at Princeton University. Originally published in 1978.

Download or read book Snake Venoms written by C.-Y. Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has been a period of explosion of knowledge on the chemistry and pharmacology of snake toxins. Thanks to the development of protein chemistry, nearly a hundred snake toxins have been purified and sequenced, representing one of the largest families of sequenced proteins. Moreover, the mode of action of these toxins has been largely elucidated by the concerted efforts of pharmacologists, electro physiologists, and biochemists. As a result of these studies, some of the snake toxins, e.g., a-bungarotoxin and cobra neurotoxins, have been extensively used as specific markers in the study of the acetylcholine receptors. Indeed, without the discovery of these snake toxins, our knowledge of the structure and function of nicotinic acetylcholine receptors would not have advanced so rapidly. The contribution of snake venom research to the biomedical sciences is not limited to the study of cholinergic receptors. Being one of the most concentrated enzyme sources in nature, snake venoms are also valuable tools in biochemical research. Venom phosphodiesterase, for example, has been widely used for structural studies of nucleic acids; proteinase, for the sequence studies of proteins and pep tides ; phospholipase A , for lipid research; and L-amino acid oxidase for identifying optical z isomers of amino acids. Furthermore, snake venoms have proven to be useful agents for clarifying some basic concepts on blood coagulation and some venom enzymes, e.g., thrombin-like enzymes and pro coagulants have been used as therapeutic agents.

Download or read book The Amphibians and Reptiles of Costa Rica written by Jay M. Savage and published by University of Chicago Press. This book was released on 2002-08 with total page 1076 pages. Available in PDF, EPUB and Kindle. Book excerpt: World renowned for its biological diversity and model conservation system, Costa Rica is home to a wide variety of amphibians and reptiles, from the golden toad to the scorpion lizard and the black-headed bushmaster. Jay M. Savage has studied these fascinating creatures for more than forty years, and in The Amphibians and Reptiles of Costa Rica he provides the most comprehensive, up-to-date treatment of their biology and evolution ever produced. Savage begins with detailed discussions of the natural and cultural history of Costa Rica, setting the stage for a detailed treatment of each of the 396 species of amphibians and reptiles that may be found there. Each species account synthesizes and analyzes everything that is known about the animal's anatomy, behavior, geographic distribution, systematics, and evolutionary history and provides keys for identifying amphibians and reptiles in the field. In addition to distribution maps and systematic and morphological illustrations, the book includes color photographs of almost every known species, many taken by the distinguished nature photographers Michael and Patricia Fogden. Because Costa Rica has played, and continues to play, a pivotal role in the study of tropical biology as well as in the development of ecotourism and ecoprospecting, and because more than half of the amphibians and reptiles in Costa Rica are also found elsewhere in Central America, The Amphibians and Reptiles of Costa Rica will be an essential book for a wide audience of nature lovers, naturalists, ecotourists, field biologists, conservationists, and government planners.
