Download or read book Fossil Frogs and Toads of North America written by J. Alan Holman and published by Indiana University Press. This book was released on 2003-12-25 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heart of this book consists of detailed systematic accounts of the known fossil frogs and toads (anurans) of North America and their localities. Extinct fossil frogs and toads are fully discussed and illustrated, and in some cases are re-diagnosed and re-described. For fossil taxa still living, the book gives the modern characteristics, ecological attributes, and modern ranges, and includes illustrations of diagnostic skeletal elements. The volume begins with an overview of the anurans and anuran studies, a general account of the skeleton and bones, and a discussion of the early evolution of the Anura, along with the formal classification of anuran taxonomic groups found in the North American fossil record. The third part of the book presents an epoch-by-epoch discussion of Mesozoic, Tertiary, and Pleistocene anurans, the classification and phylogeny of the anurans, and a comprehensive list of references.
Download or read book Tertiary Frogs from Central Europe written by Z.V. Spinar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remains of fossil frogs, elsewhere scarce, have been found abundantly for more than one hundred and twenty five years in the Tertiary deposits in northern and western Bohemia. In most cases they are imprints of complete skeletons or their parts poorly preserved in carbonaceous claystones, and difficult to interpret. A new locality of Tertiary diatomites that has been discovered in 1950 in northern Bohemia, not far from the town of DMin, is Bechlejovice. This locality yielded very interesting material: in addition to innumerable leaf imprints, frequent frog-remains were so excellently pre served that they made possible studies not only of skeletal parts but also outlines of muscles, organs, blood vessels, nerves, pigments, some cartilages, glands, etc. Up to now, numbers designating remains of adult individuals have totalled 1,100, besides 80 palaeobatrachid tadpoles. There were also found seven adult specimens and more than 60 tadpoles of pelobatids. Nor should be omitted other localities in Bohemia (see below) which furnished new material and thus much new information. Examinations made on the new finds necessitated revision of earlier collections deposited at the following Institutions: The Department of Palaeontology of Charles University, Prague; the National Museum in Prague; the State Museum for Mineralogy and Geology, Dresden; the Palaeontologic Institute and Museum of Humboldt University, Berlin (East Germany); the Institute for Geology and Palaeonto logy of Martin-Luther-Universitat, Halle-Wittenberg, DomstraBe 5, East Germany; the British Museum (Natural History), London.

Available in PDF, EPUB and Kindle. Book excerpt: "The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--

Download or read book Amphibians and Reptiles of Texas written by James Ray Dixon and published by Texas A&M University Press. This book was released on 2000 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Gnomes of the Night written by Arthur N. Bragg and published by University of Pennsylvania Press. This book was released on 2016-11-11 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the most complete account in existence of a strange group of animals—the spadefoot toads. This small group of species, which, because of their secretive and burrowing habits, the author calls "gnomes of the night," have unusually numerous interesting facts in their life history. The purpose of the book is twofold: to give a factual picture of the lives of the spadefoots, drawing upon the technical literature as well as the author's wide experience with certain species; and to illustrate how a naturalist works, the mistakes he sometimes makes, his correction of them with time and further experience, and the necessity for him to accept and examine critically the comments on his work by others. Gnomes of the Night should appeal to all zoologists, especially those whose interests are in the lives of animals in their natural habitat rather than in the laboratory. Illustrated with maps and photographs, it is a scholarly and fascinating account of little-known but prevalent animals.

Download or read book Evolution of Desert Biota written by David W. Goodall and published by University of Texas Press. This book was released on 2014-07-09 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by specialists in the field, the papers in this volume explore evolution of animals and plants on the deserts of North America, South America, and Australia. Together, the articles constitute a complete survey of the geological history of the deserts of three continents, the evolution of the animals and plants of those deserts, and their adaptations to the environments in which they live. The first paper, by Otto T. Solbrig, discusses the flora of the South American temperate and semidesert regions, citing numerous genera and reasons that they are found in the different areas. John S. Beard uses the same approach in his discussion of the evolution of Australian desert plants and focuses on western Australian areas. Guillermo Sarmiento appraises the evolution of arid vegetation in tropical America, including the Lesser Antilles and the Coast Range of Venezuela and Colombia. A. R. Main surveys the adaptation of Australian vertebrates to desert conditions and gives examples of how various species of birds, reptiles, and amphibians adapt to their environment in order for the greatest number to survive. James A. MacMahon designates specific communities in the Mojave, Sonoran, and Chihuahuan deserts and discusses the similarity of species of the North American desert mammal faunas found there, while Bobbi S. Low focuses on the evolution of amphibian life histories in the desert and compiles a lengthy table of amphibia comparing egg size, habitat, number of eggs per clutch, and so forth. Finally, W. Frank Blair treats adaptation of anurans to equivalent desert scrub of North and South America and cites various species of frogs and toads that are found in similar areas. The volume also includes an introduction by the editor and an index. Evolution of Desert Biota is the result of a symposium held during the First International Congress of Systematic and Evolutionary Biology in Boulder, Colorado; in August 1973.
