Leafcutter ants will cope with global warming, urban study shows
Leafcutter ants Atta sexdens living in the city of São Paulo, Brazil, can tolerate higher temperatures than their rural counterparts, according to a study published this week. The urban jungle can be as much as 12 degrees C hotter than the countryside, making it a great testing ground for understanding how life might cope with future climate change, say the study’s authors, an international team led by Indiana State University’s Michael Angilletta Jr. It’s not clear whether the ant’s increased ability to stand the heat is genetically based or down to “heat hardening”, but the result is the same: some day, ants will indeed take over the world
