With its sub-tropical climate and international ports, Florida is especially vulnerable to invasive and exotic species. Host Diane Trees and two biologists explore the creatures that have taken up residence in the state, where they come from and why they’re a problem. Guests: Dr. Linda Walters, professor of biology at the University of Central Florida, and Sarah Funck from the Florida Fish and Wildlife Conservation Commission.
