About The Cover

Marbled salamanders (Ambystoma opacum) are among the many amphibian species that breed at Carolina bays, natural wetlands of the southeastern Atlantic Coastal Plain. Ambystoma opacum is one of the amphibian species that has been monitored daily at a protected wetland, Rainbow Bay in South Carolina, for the past 12 years by investigators at the Savannah River Ecology Laboratory.
