The widespread appearance of frogs with deformed bodies has generated much press coverage over the past decade. Frogs with extra limbs or digits, missing limbs or digits, or misaligned appendages raise an alarming question: "Are deformed humans next?" Taking a fresh look at this disturbing environmental problem, this reference provides a balanced overview of the science behind the malformed frog phenomenon. Bringing together data from ecology, parasitology, and other disciplines, Michael Lannoo considers the possible causes of these deformities, tells which frogs have been affected, and addresses questions about what these malformations might mean to human populations. Featuring high-quality radiographic images, Malformed Frogs suggests that our focus should be on finding practical solutions, a key component of which will be controlling chemical, nutrient, and pesticide runoff into wetlands.

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.

Over the past several years, extraordinary numbers of deformed frogs have been discovered, not only in the waters of Minnesota, but in lakes and ponds across the U.S., Canada, and as far away as Japan. The frog -- an animal that lives in ponds and on land, that breathes through its skin, that lays its clear, absorbent eggs in open, sunlit water -- is a indicator of environmental conditions. This book follows the mystery of the deformed frogs and the search for answers. Souder had access to all the key scientists, and has followed every aspect of the story, from back room discussions and conferences at the Federal government level to the secret hot spots where the highest percentage of deformed frogs are found.

Recent estimates suggest that nearly 3 million people in the US alone keep an amphibian or reptile as a pet. YouTube videos with odes to cane toads are ubiquitous. And yet amphibians and reptiles also keep extermination companies in business, and are reviled by many. These emotions pose great challenges to the conservation of these species, just as their populations in the natural world are in great decline. It can be quite hard to inspire stewardship of a tomato toad in the same way that one can more generally charismatic fauna like pandas and polar bears. In response, herpetologists have created large-scale programs such as Amphibian Ark, the umbrella organization behind the Year of the Frog campaign, http: //www.amphibianark.org/, to educate and enthrall citizens with the charm of the more slimy species of the planet. Few herpetologists have contributed more to the conservation of amphibians and reptiles than Marty Crump, a renowned expert on declining amphibians. This manuscript is her ode to the toad, a masterful compilation of science and narrative centering on human relations with amphibians and reptiles across the globe. An intrepid explorer and skilled writer, Crump has gathered stories and myths and paired them with natural history to give a wonderful view of how essential amphibians and reptiles are to our well being. Using symbolism, folklore, and science, the manuscript also explores the conservation consequences of our complicated amorous and vexed affair with snakes, frogs, toads and other herpetofauna.
