Langkilde and her colleagues wanted to know the short- and long-term physiological effects on fence lizards due to invading fire ants. Langkilde's prior research showed that lizards in ...

Some lizards have developed long legs and a dance move that helps them avoid being possibly eaten alive by lethal fire ants. Fire ants from South America, called Solenopsis invicta, were introduced to ...

Native fence lizards in the southeastern United States are adapting to potentially fatal invasive fire-ant attacks by developing behaviors that enable them to escape from the ants, as well as by ...
