Download or read book The Amphibians and Reptiles of Alberta written by Anthony Patrick Russell and published by University of Calgary Press. This book was released on 2000 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibians and reptiles (herpetofauna) are a significant but much-neglected component of the natural economy of the province of Alberta. The Amphibians and Reptiles of Alberta, Second Edition continues both as a field guide and a comprehensive natural history, builds on the strengths of the first with a richly illustrated text and colour photographs of the species taken by renowned wildlife photographer Wayne Lynch. The Amphibians and Reptiles of Alberta, First Edition won an Emerald Award for Environmental Excellence and an award from the Book Publishers Association of Alberta. This second edition has been thoroughly revised and updated. Nomenclature has been changed to reflect current thinking in the field. New photographs have been added, and maps and illustrations have been updated. This is the essential reference for Alberta herpetofauna.

Download or read book Amphibian Declines written by Michael Lannoo and published by Univ of California Press. This book was released on 2005-06-15 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.

The editor presents a collection of topics explaining the migration of organisms through many examples of different groups of marine and non-marine organisms, from micro-invertebrates to large mammals.

Available in PDF, EPUB and Kindle. Book excerpt: Although reptiles and amphibians are different classes of vertebrates, they have long been studied together in the field of herpetology. This guide provides an account of the herpetology of Montana, first providing descriptions of herpetofauna biology, habitats in Montana, field observation, and conservation and management, then moving onto species accounts of 36 salamanders, frogs, toads, turtles, lizards, and snakes occurring in the western state. Including numerous color photographs, the species accounts provide information on morphology, taxonomy and distribution, habitat and behavior, and reproduction and development. Also provided are a simplified key to aid identification, a glossary, and appendices detailing reproductive features and other information.

Download or read book Salamanders written by Rashid Gerasimov and published by Nova Science Publishers. This book was released on 2020-12 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Waterton Lakes National Park, located in southwest Alberta, Canada, under-road crossing structures were installed in 2008 to protect a population of long-toed salamander (Ambystoma macrodactylum) at Linnet Lake from mortality during breeding migrations that intersected with the park's entrance road. This compilation first investigates orientation and movement patterns of marked individuals at Linnet Lake in 2013 and 2014, and at a smaller, shallower wetland Stable Pond in 2014 to document in detail how long-toed salamanders used the terrestrial landscape around breeding sites during adult migration and juvenile dispersal. Following this, the authors use generalized linear models to model salamander occurrence and abundance in the Beaver Hills region of north-central Alberta as a function of land cover type and pocket gopher density. The authors go on to address whether any ecological barriers exist in the distribution range of the two newt species N. strauchii and N. crocatus. According to the findings of this study, an identity test was found to be significantly different from the null distribution, whereas a background test was not significantly different from the null distribution. The concluding chapter summarizes the processes by which light is converted into neural signals by rods and cones and then transmitted to downstream neurons in the retina, with a focus on salamander photoreceptors. The different types of photoreceptor cells and other light-sensitive cells in salamanders and their role in vision are also discussed.
