A Natural History of Amphibians
Author: Robert C. Stebbins
language: en
Publisher: Princeton University Press
Release Date: 2021-08-10
This is a book for all readers who want to learn about amphibians, the animal group that includes frogs, toads, salamanders, and caecilians. It draws on many years of classroom teaching, laboratory experience, and field observation by the authors. Robert Stebbins and Nathan Cohen lead readers on a fascinating odyssey as they explore some of nature's most interesting creatures, interspersing their own observations throughout the book. A Natural History of Amphibians can serve as a textbook for students and independent learners, as an overview of the field for professional scientists and land managers, and as an engaging introduction for general readers. The class Amphibia contains more than 4,500 known living species. New species are being discovered so rapidly that the number may grow to more than 5,000 during our lifetimes. However, their numbers are being rapidly decimated around the globe, largely due to the encroachment of humans on amphibian habitats and from growing human-caused environmental pollution, discussed at length in the final chapter. The authors focus our attention on the "natural history" of amphibians worldwide and emphasize their interactions with their environments over time: where they live; how they reproduce; how they have been affected by evolutionary processes; what factors will determine their destinies over time. Through the experienced eyes of the authors, who are skilled observers, we come to see and understand the place of amphibians in the natural world around us.
Ecology and Conservation of Amphibians

Release Date: 1996-03-31
This volume sets out to provide an overview of recent research on all aspects of amphibian ecology and behaviour and to illustrate its application to practical conservation measures for this major group of animals. Its broad scope makes it of relevance to students of general biology, ecology and conservation, but also to professionals in industries and agencies involved with environmental issues and nature conservation.
Amphibian Killers
""Amphibian Killers"" explores the captivating world of amphibian survival, revealing how these creatures employ remarkable strategies for both hunting and defending themselves. The book delves into the evolutionary pressures that have shaped their unique adaptations, particularly focusing on their potent toxins and intricate hunting techniques. Readers will discover how amphibians, from ambush predators like bullfrogs to toxin-laden poison dart frogs, play pivotal roles in maintaining biodiversity and ecological balance. One intriguing aspect is how some amphibians sequester toxins from their insect prey, turning their food into a formidable defense. The book progresses from an introduction to amphibian classification and ecological roles to detailed examinations of their hunting strategies and defense mechanisms. Special emphasis is given to the chemistry and pharmacology of amphibian toxins, revealing their potential applications in medicine. It highlights the importance of understanding predator-prey relationships and offers insights into the conservation challenges these fascinating species face. By integrating ecological and evolutionary perspectives with chemical analyses, ""Amphibian Killers"" provides a comprehensive and accessible overview, making it a valuable resource for anyone interested in nature, biology, and the science of life.
