LITTLE ROCK, Ark. - A biologist from the University of Arkansas is set to give a talk about problems with invasive pythons.

Professor J.D. Willson is to speak at the Clinton School of Public Service at noon Friday.

Willson joined the UA faculty last year and is doing research on amphibians, aquatic reptiles, and invasive snakes. That includes work examining the impact of invasive Burmese pythons in the Florida Everglades.

The snakes have troubled Florida's fragile ecosystem since 1992, when Burmese pythons were released into the wild after Hurricane Andrew destroyed many pet shops.

Wildlife officials in Florida are working to cull the snakes from the Everglades and other wilderness.
