All records on the maps are based upon actual specimen data which was exported from the UMMZ Herpetology database (FoxPro) into ArcView. The maps were exported as jpeg files from ArcView.
The photographs are courtesy of the Animal Diversity Web, based at the University of Michigan. Frog calls are courtesy of Dr. Alan Wolf, a former student at the UMMZ.
