Native lizards evolve to escape attacks by fire ants

Penn State Assistant Professor of Biology Tracy Langkilde has shown that native fence lizards in the southeastern United States are adapting to potentially fatal invasive fire-ant attacks by developing behaviours that enable them to escape from the ants, as well as by developing longer hind legs, which can increase the effectiveness of this behaviour. 'Not only does this finding provide biologists with an example of evolution in action, but it also provides wildlife managers with knowledge that they can use to develop plans for managing invasive species,' said Langkilde...
