Amphibian Declines - The Conservation Status of United States Species by 
Frogs: The Animal Answer Guide by
Frogs are amazingly diverse—ranging from the massive goliath frog, which weighs several pounds, to the recently discovered gold frog, which measures a mere three-eighths of an inch when fully grown—and have inhabited the earth for more than 200 million years. Today, however, these amphibians face more challenges than any other vertebrate group. In this fun and informative book, herpetologists Mike Dorcas and Whit Gibbons answer common and not-so-common questions people may have about these fascinating animals. Dorcas and Gibbons discuss how frogs evolved, which species currently exist in the world, and why some have recently gone extinct. They reveal what frogs eat and what eats them, their role in cultures across the globe, why many populations are declining and what we can do to reverse this dangerous trend, why there are deformed frogs, and much more. They answer expected questions such as "What is the difference between a frog and a toad?" and "Why do some people lick toads?" and unexpected ones such as "Why do some frogs lay their eggs in the leaves of trees?" and "Do frogs feel pain?" The authors’ easy-to-understand yet thorough explanations provide insight into the amazing biology of this amphibian group. In addressing conservation questions, Dorcas and Gibbons highlight the frightening implications of the current worldwide amphibian crisis, which many scientists predict will bring extinction rates experienced by frog species to levels not seen in any vertebrate animal group in millions of years. Packed with facts and featuring two color galleries and 70 black-and-white photographs, Frogs: The Animal Answer Guide is sure to address the questions on the minds of curious naturalists.
Handbook of Larval Amphibians of the United States and Canada by
Generously illustrated, this essential handbook for herpetologists, ecologists, and naturalists features comprehensive keys to eggs, embryos, salamander larvae, and tadpoles; species accounts; a glossary of terms; and an extensive bibliography. The taxonomic accounts include a summarization of the morphology and basic natural history, as well as an introduction to published information for each species. Tadpole mouthparts exhibit major characteristics used in identifications, and the book includes illustrations for a number of species. Color photographs of larvae of many species are also presented. Handbook of Larval Amphibians of the United States and Canada, written by the foremost experts on larval amphibians, is the first guide of its kind and will transform the fieldwork of scientists and fish and wildlife professionals.
Marsupial Frogs: Gastrotheca and Allied Genera by
This scientific masterpiece reveals many aspects of the lives of marsupial frogs and closely allied genera. Native to Central and South America, these amphibians differ from other frogs in that they protect their eggs after oviposition by either adhering them to the female’s back or placing them in a specialized dorsal pouch (thus the common name, marsupial frog). During mating, the male typically collects the eggs from the female with his feet—often one at a time and always out of water—fertilizes them, and then tucks them into the female’s pouch or attaches them to her back. In some species these eggs hatch as tadpoles, but most emerge as miniatures of the adults. Even among the tadpoles there is remarkable divergence, with some behaving in the typical manner (feeding and metamorphosing), whereas others forego all feeding until they metamorphose. In Marsupial Frogs, William E. Duellman’s synthesis of all that is known about the unique family Hemiphractidae is largely based on decades of his own careful laboratory and field study. He reveals the diversity of exotic color patterns and the frogs' geographic distributions by providing more than 200 photographs, illustrations, and maps. This exceptional tome should find its way into the libraries of serious herpetologists, tropical biologists, and developmental biologists. Included in this book are • A molecular phylogeny of the family Hemiphractidae • A thorough osteological analysis • A review of external morphological features • An overview of the evolution of reproductive modes • A biogeographic synthesis • Keys to genera and species • Diagnosis and thorough description of each species of marsupial frog • Colored physiographic maps depicting species distributions
Peril in the Ponds: Deformed Frogs, Politics, and a Biologist's Quest by
Peril in the Ponds tells the story of a government biologist's investigation into the mystery of deformed frogs, an epidemic that grew during the 1990s and continues today. It provides an inside view of a highly charged environmental issue that aroused the attention of the public and the media and sparked controversies among scientists, politicians, and government agencies. By the 1990s, wetlands across the United States were endangered from pollution and decades of drainage to convert them into farmland and urban developments. But 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? Judy Helgen writes with passionate concern about vulnerable frogs and wetlands as she navigates through a maze of inquisitive media and a reluctant government agency. She reports on the complexity of a growing catastrophe for frogs and broadens the issue as she researches and meets with scientists from around the world. She affirms the importance of examining aquatic life to understand pollution and the need to rescue our remaining wetlands. She also shares the fears expressed by the teachers, students, and other citizens who found these creatures, sensed a problem, and looked to her for answers. Ultimately, this is a story about the biological beauty of wetlands and our need to pay attention to the environment around us.
