When deformed frogs-many with missing legs or eyes, footless stumps, or misshapen jaws-began to emerge from Minnesota wetlands, alarm bells went off. What caused such deformities? Pollution? Ultraviolet rays? Biological agents? And could the mysterious cause also pose a threat to humans? Former government biologist Judy Helgen provides an inside view of a highly charged environmental issue that continues to spark controversy among scientists, politicians, and government agencies.

The most thorough, updated guide to frogs and toads in the United States and Canada available. A stunning diversity of frog species can be found from coastal swamps to lofty mountain peaks, and from the Florida Keys to the Arctic Ocean. They live in subtropical lowlands, grassland prairies, deserts, and alpine-tundra habitats. Some species have restricted habitat requirements, whereas others occur contiguously from the arid plains or humid southeastern forests to the high tundra. In this new edition of Frogs of the United States and Canada, C. Kenneth Dodd Jr. tours the reader through the marvelous world of North American frogs. Covering 114 native and introduced species from all US states and Canadian provinces, this comprehensive reference on the biology, behavior, and conservation of the Order Anura includes detailed and updated information on • past and present distribution • life history and demography • reproduction and diet • landscape ecology and evolution • diseases, parasites, and threats from toxic substances • conservation and management Hundreds of occurrence maps, line drawings, and new color photographs of frogs and their habitats enhance the text. The most thorough treatment of the life histories, distribution, and status of North American frogs ever produced, Frogs of the United States and Canada has been the go-to reference for naturalists, scientists, and resource managers in their efforts to understand and conserve frogs, their habitats, and biodiversity for over a decade. Based on a meticulously updated examination of more than 8,000 references current through 2021, this second edition ensures Dodd's master work will remain an unparalleled resource for years to come.

This book is an in-depth look at the natural history of each snake and lizard species/subspecies found in Iowa. Each of the thirty-three species accounts includes a sampling of the common names the species has been known by in the past, the first specimens collected in the state, and a brief history of the early Iowa literature related to the species, along with a complete description and a discussion of similar species, distribution in the state, habitat, behavior, threats, foods and feeding, and reproduction. While readers will be able to identify Iowa’s snakes and lizards through its species accounts, identification keys, and beautiful photographs and illustrations, this book is intended to be more than a field guide. What makes it truly unique is the comparison of historic data collected by Iowa herpetologists in the 1930s and 1940s with data collected by the author, along with James L. Christiansen and others, since 1960. Custom maps show the reader how species’ distributions have changed over time.
