Recent intense scrutiny of amphibian conservation status makes this title a timely archive in the context of the frog's dramatic decline. Frogs are adversely affected by loss of habitat, pollution by agricultural and industrial chemicals, and climate change. As such, the frog is an important pollutant indicator. This book will profile 600 species, representing the remarkable diversity of frogs, each species photographed life-size to capture its delicate detail, and accompanied by an in-depth species profile.
