In 1990 an international group of biologists, meeting to discuss rumors of declines in the number of amphibians, discovered that amphibian disappearances once thought to be a local problem were not--the problem was global. And, even more disturbing, amphibians were disappearing not just from areas settled by humans but from regions of the world once believed to be pristine. Under the mantle of the Declining Amphibian Populations Task Force, this timely book addresses three fundamental questions for the midwestern United States: are amphibians declining; if so, why; and, if so, what can be done to halt these losses? In the Midwest--defined here as Missouri, Iowa, Illinois, Indiana, Ohio, Minnesota, Wisconsin, and Michigan--there can be no doubt that the number of salamanders and frogs has declined with Euro-American settlement and the conversion to an agriculturally dominated landscape. Habitat loss and landscape fragmentation have been major factors in this decline, as have aquacultural uses of natural wetlands. Bullfrog introductions have eliminated populations of native amphibians, and collecting for the biological supply trade has reduced the number of individuals within many populations. The goal of the forty-two essays in this well-documented, well-illustrated book is to put between two covers all we know now about the status of midwestern amphibians. By doing this, the editor has created a readily accessible historical record for future studies. Organized into sections covering landscape patterns and biogeography, species status, regional and state status, diseases and toxins, conservation, and monitoring and applications, this landmark volume will serve as the foundation for amphibian conservation in the Midwest.

Most people do not realize it, but the Midwest has been at the forefront of ecological restoration longer than perhaps any other region in the United States, dating back to the 1930s. Because of its industrial history, agricultural productivity, and natural features such as the Great Lakes, the Midwest has always faced a unique set of ecological challenges. Focusing on six cutting-edge case studies that highlight thirty restoration efforts and research sites throughout the region— Iowa, Indiana, Illinois, Wisconsin, Michigan, Minnesota, and Ohio— editors Christian Lenhart and Peter “Rocky” Smiley Jr. bring together a group of scholars and practitioners to show how midwestern restoration efforts have developed, as well as where they are headed. Whether cleaning up contamination from auto plants in Ohio, or restoring native prairie grasses along the Iowa highway, the contributors uncover a vast network of interested citizens and volunteer groups committed to preserving the region’s environment. This study, intended for researchers, students, and practitioners, also provides an updated synthesis of restoration theory and practice, and pinpoints emerging issues of importance in the Midwest, such as climate change and the increase in invasive species it will bring to the region. Though focusing exclusively on the Midwest, the contributors demonstrate how these case studies apply to restoration efforts across the globe. Contributors: Luther Aadland, David P. Benson, Andrew F.

Describes the latest methodologies used to study the ecology of amphibians throughout the world. Each of the 27 chapters explains a research approach or technique, with emphasis on careful planning and the potential biases of techniques. Statistical modelling, landscape ecology, and disease are covered for the first time in a techniques handbook.

"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"--
