Lizards adapt to invasive fire ants, reversing geographical patterns in traits

Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study by researchers from Penn State reveals that new environmental challenges can override the historical influences that originally determined geographical trends in traits.
