Book excerpt: During the last half century, lungless salamanders (Family Plethodontidae) have been the subject of numerous studies in the fields of ecology and genetics. While most works have focused on the species-rich Eastern Highlands region, there has been a recent shift towards plethodontid assemblages within the Coastal Plain. The research presented herein applies hierarchical occupancy models and both mitochondrial and nuclear genes to address questions pertinent to the biology and conservation of plethodontids within the Gulf Coastal Plain. The results of a multi-species Bayesian single-season occupancy model indicated that two environmental gradients, upstream drainage area and stream drying, influenced the probability of occurrence for multiple species of stream-breeding plethodontids. Further, species varied in their responses to these gradients. A second model was used to ask whether asymmetric interactions also influenced occurrence for three species of brook salamanders (Genus Eurycea). More specifically, the model tested whether the southern two-lined salamander (E. cirrigera) might act as the dominant predator and or competitor to either the three-lined (E. guttolineata) or dwarf (E. quadridigitata) salamanders. The results of this second model suggested that environmental gradients likely work in tandem with negative interactions to shape the distribution of E. guttolienata within the Gulf Coastal Plain. Like hierarchical occupancy models, genetic tools are also shedding light on complex relationships among and within species of lungless salamanders. This research investigated phylogeographic patterns within a wide-ranging species of plethodontid, the spotted dusky salamander (Desmognathus conanti). Sequence data revealed that there were geographically discrete, deeply divergent mitochondrial lineages within D. conanti which may be the result of isolation brought about by fluctuating sea levels during the late Miocene through the Pleistocene. Data from six rapidly mutating microsatellite markers indicated that there had been recent gene flow across some of these lineages in the southern Gulf Coastal Plain. However, these data also suggest that a northern lineage may have remained distinct. The relationships described and occurrence probabilities estimated by the aforementioned models, in combination with conclusions from analyses of genetic data, improve our ability to conserve regional plethodontid biodiversity within this unique physiographic province.

Book Synopsis Key to the Herpetofauna of the Continental United States and Canada by : Robert Powell
Download or read book Key to the Herpetofauna of the Continental United States and Canada written by Robert Powell and published by University Press of Kansas. This book was released on 2019-07-26 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This profusely illustrated comprehensive key for identifying amphibians and reptiles from the continental United States and Canada incorporates a wealth of scientific findings. Since the first edition was published in 1998 and the second in 2012, the number of currently recognized species of native amphibians and reptiles in the area covered by this key has increased from 545 to 634 to 685, and the number of established non-native species has increased from 39 to 58 to 67. The increase in native taxa reflects the dynamic nature of modern systematics and the use of new (especially molecular) techniques to elucidate relationships and redefine species boundaries. The increase in non-native species reflects the porosity of the North American borders when it comes to controlling animal imports. The key is easy to use and illustrated with outstanding line drawings that show details of color patterns and structures used for identification. To accommodate the additional taxa, the number of line drawings in this third edition has increased from 257 to 279 to 295. In addition, nine maps illustrate the distributions of species that have been recognized since the publication of maps in the most recent editions of the Peterson Field Guides to the reptiles and amphibians of eastern, central, and western North America. A large number of annotations detail current taxonomic ambiguities or disagreements and the literature cited has been expanded. Collectively these features enhance opportunities to teach and learn the classification and identification of amphibians and reptiles in the continental United States and Canada.

Book Synopsis Amphibian Evolution by : Rainer R. Schoch
Download or read book Amphibian Evolution written by Rainer R. Schoch and published by John Wiley & Sons. This book was released on 2014-03-19 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the first vertebrates to conquer land and their long journey to become fully independent from the water. It traces the origin of tetrapod features and tries to explain how and why they transformed into organs that permit life on land. Although the major frame of the topic lies in the past 370 million years and necessarily deals with many fossils, it is far from restricted to paleontology. The aim is to achieve a comprehensive picture of amphibian evolution. It focuses on major questions in current paleobiology: how diverse were the early tetrapods? In which environments did they live, and how did they come to be preserved? What do we know about the soft body of extinct amphibians, and what does that tell us about the evolution of crucial organs during the transition to land? How did early amphibians develop and grow, and which were the major factors of their evolution? The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, and is edited by Professor Mike Benton, University of Bristol. Books in the series provide a summary of the current state of knowledge, a trusted route into the primary literature, and will act as pointers for future directions for research. As well as volumes on individual groups, the series will also deal with topics that have a cross-cutting relevance, such as the evolution of significant ecosystems, particular key times and events in the history of life, climate change, and the application of a new techniques such as molecular palaeontology. The books are written by leading international experts and will be pitched at a level suitable for advanced undergraduates, postgraduates, and researchers in both the paleontological and biological sciences.

Book excerpt: "Amphibians are facing an extinction crisis, but getting to the facts has been difficult. "Threatened Amphibians of the World" is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians. All 1,900 species known to be threatened with extinction are covered, including a description of threats to each species and an evaluation of conservation measures in place or needed. Each entry includes a photograph or illustration of the species where available, a distribution map, and detailed information on range, population and habitat and ecology. Introductory chapters present a detailed analysis of the results, complemented by a series of short essays written by many of the world's leading herpetologists. Appendices include annoted lists of lower risk species and a country-by-country listing of threatened amphibians."--pub. desc.
