DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOK". . . encourage[s] hope and resilience in times of devastating damage."—New York Review of Books This user-friendly guide is the only complete resource that identifies and describes all the amphibians and reptiles—salamanders, frogs and toads, lizards, snakes, and tortoises and turtles—that live in California. The species are described in richly detailed accounts that include range maps, lifelike color paintings by Robert C. Stebbins, clear drawings of various life stages including eggs, notes on natural history, and conservation status. Easy-to-use keys for every order help identify species, and informative chapters cover more general topics including evolution, habitat loss, and photography. Throughout, anecdotes and observations reveal new insights into the lives of California’s abundant but often hidden amphibians and reptiles.

DOWNLOAD EBOOKThe field of amphibian microbial ecology has greatly advanced in recent years. The work published to date has shown that amphibian skin bacterial communities can be influenced by host species, host life-history stage, environmental conditions, surrounding bacterial communities that serve as reservoirs and external biotic agents such as pathogens. As the ecology of amphibian-microbial symbiosis is a relatively new field, there are still many unanswered questions. The aim of this Research Topic is to highlight recent research on amphibian microbiomes that addresses relevant questions on the ecology of amphibian-microbe interactions. The publications gathered in this Research Topic have expanded our knowledge on the role of microbial symbionts of amphibians and have revealed novel insights that can direct the next set of research questions. We suggest that soon the field will move from the basic (and necessary) descriptions of microbial communities to more experimental approaches that include the use of omics methods and a variety of novel analytic and multivariate approaches. In addition to providing more insights into the microbial and disease ecology of amphibians, these studies may lead to effective ways to manipulate the microbiome to achieve protection from diseases, such as chytridiomycosis.
