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

With richly colorful photos and compelling, informative descriptions, John and Deborah Behler have carefully crafted a wonderful tribute to the amazingly complex frog. With decades of expertise in conservation, the Behlers are unequaled in their ability to capture the wild and ever-changing world of these amphibians--all 5,000 species. They reveal an unexpected diversity of form, lifestyle, and ecology, and take readers on a magical journey that makes vibrantly clear why these creatures are so important. Breathtaking and brilliant images show tadpoles in water and on leaves; a many-hued variety of frogs (bright blue, golden yellow and black, red and turquoise) in their environment; African sand frogs and chirping frogs; Oriental fire-bellied frogs; and tiny three-toed toadlets--among the smallest that exist. It’s a vision not to be missed.

The organizer area plays a central role in the formation of the embryonic axis and the central nervous system of all vertebrates including the human fetus. In The Vertebrate Organizer, outstanding molecular development biologists and embryologists report their latest approaches in this fascinating research area using different vertebrate model organisms. The presented data is of central importance for the understanding of early human embryogenesis.

Boys' Life is the official youth magazine for the Boy Scouts of America. Published since 1911, it contains a proven mix of news, nature, sports, history, fiction, science, comics, and Scouting.

In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.

A richly illustrated guide to the world’s frogs that includes species from every family With more than 7,600 known species, frogs exhibit an extraordinary range of forms and behaviors, from those that produce toxins so deadly that they could kill a human many times over to those that can survive being frozen in ice. Frogs of the World is an essential guide to this astonishingly diverse group of animals. An in-depth introduction covers everything from the origins and evolution of frogs to their life cycles and defense strategies. Beautiful illustrations accompany profiles of species from each family, shedding invaluable light on the enormous range of appearance, habitats, and behavior of these marvelous creatures. Features hundreds of stunning color photographs Covers taxonomy, anatomy, locomotion, reproduction, diet, and more Discusses the conservation of the world’s frogs An invaluable resource for herpetologists, naturalists, and anyone interested in amphibians
