D. M. Green (ed.) Amphibians in Decline: Canadian Studies of a Global Problem
St. Louis, MO SSAR 1997 0-916984-40-0 / 9780916984403 Paperback New No
PB; Chapters by 53 authors dealing with population dispersal and fluctuations, genetic diversity, monitoring of natural populations, as well as effects of temperature, acidity, pesticides, UV light, forestry practices, and disease. // This book constitutes the report to the IUCN Declining Amphibian Populations Task Force (DAPTF) from the Canadian Declining Amphibian Population Working Group (DAPCAN). The 29 refereed chapters from 53 authors include demographic and population studies, status reports, descriptions of methods (including 2 analyes of calling amphibian surveys), and studies or reviews of causes of amphibian declines, including pesticides, global change and UV radiation, and disease. A comprehensive appendix describes status of all 47 species of Canadian amphibians and includes photographs of most of them. // The original DAPTF charge to the regional working groups was to ascertain whether amphibian populations were in decline in each working group region, and if so, to identify the suspected causes. No suggestions for structure or function of the working groups were at first supplied. Thus working groups were on their own to determine how amphibian declines could be documented and to determine what factors might be involved. In reality, the definition and documentation of amphibian declines is not at all straightforward. to its credit, DAPCAN struggled with these basic questions. this publication provides valuable case history information on how to approach studies of amphibian populations and, importantly, offers recommendations for the kinds of studies that are most useful in documenting amphibian declines. DAPCAN has been extremely successful and effective in its role as a DAPTF regional working group. This publication, the fulfillment of DAPCAN's mandate from DAPTF is an example of thier success and sets a high standard for all subsequent DAPTF working group reports. - W. Ron Heyer, DAPTF Chair (from the Foreword).

J. C. Mitchell, R. E. Jung Brown and B. Bartholomew (ed.) Urban Herpetology
Salt Lake City SSAR 2008 0916984796 / 9780916984793 Clothbound New New No
Human impacts on herpetofauna have been pervasive for millennia largely through direct persecution of amphibians and reptiles for food or out of fear and through habitat alteration through agriculture. Only since the start of the industrial age has urbanization caused essentially permanent loss of natural habitats and the subsequent impacts on these animals. Herpetologists in some parts of the world, notably Europe, Russia, Australia, and the United States have actively engaged in research to elucidate the impacts of this human-generated phenomenon. Yet, the pervasiveness and rate of urban sprawl is progressing at such a rapid pace that we have been unable to ameliorate or prevent population extirpations and species declines. This, we believe, is partly a consequence of the lack of recognition of urban herpetology as a fruitful and critical endeavor. Our aim in this book is to show that studies of amphibians and reptiles in urban systems have much to offer scientists, conservation biologists, and land managers. We asked colleagues from countries around the world to submit original research papers or reviews on a wide variety of topics related to urban herpetology to illustrate this perception. The resulting 40 chapters and 13 case studies in this book will, we hope, set the stage for future research and conservation efforts around the world.
