Description

The Amphibian Visual System: A Multidisciplinary Approach is a compendium of articles across a broad range of disciplines within experimental biology focusing on the study of the amphibian visual system. The book presents a survey of the evolutionary history and major taxonomic and ecological adaptations of amphibians; anatomic, physiological, developmental, and behavioral data relating to the amphibian visual system; description of important standards for laboratory amphibians; and the crucial problem of species identification in neurobiological research. Zoologists, experimental biologists, neurologists, and anatomists will find the text very interesting.
