Where are the venomous snakes? An app created by a Clemson scientist can tell you

Read the full story from Clemson University.

Recent Clemson University Ph.D. graduate Rhett Rautsaw wanted to explore whether the evolutionary theory of character displacement — when two species live in the same area and evolve to avoid competing over resources such as food — extended to pit viper venom.

There was one problem. To study competition, Rautsaw had to know where each pit viper species lived, and there wasn’t a comprehensive source of that information readily available.

Rautsaw created VenomMaps, a database and web application containing updated distribution maps and niche models for all 158 pit viper species living in North, Central and South America. Pit vipers are a group of venomous snakes, including rattlesnakes, copperheads and cottonmouths. While Rautsaw needed the information for his evolutionary biology research, the maps provide vital information for conservation efforts, citizen scientists and medical professionals.
