Rattlesnakes of Arizona, Volume 2: Conservation, Behavior, Venom, and Evolution is a collection of 13 highly focused, synthetic chapters by 22 leading experts covering a wide range of topics, from phylogenetics and genomics to reproduction and social behavior. Emphasis is on species of Arizona and nearby areas in the Southwest. Conservation is highlighted in two chapters. Several chapters are dedicated solely to the development and evolution of the rattle. No academic book on rattlesnakes would be complete without a chapter on venom. Like its companion (Rattlesnakes of Arizona, Volume 1), it is replete with remarkable images of rattlesnakes in situ, as well as 90 figures and 17 tables. It is the new authoritative reference on these iconic animals.
