Entomologist Ted Schultz, the curator of ants at the Smithsonian’s National Museum of Natural History and the lead author of the new paper, on an ant-collecting expedition to the Acarai Mountains of southern Guyana in October 2006.
Schultz has spent 35 years studying the evolutionary relationship between ants and fungi. He has conducted more than 30 expeditions to locales in Central and South America to observe this interaction in the wild and has reared colonies of leafcutter and other fungus-farming ants in his lab at the museum. Over the years, Schultz and colleagues have collected thousands of genetic samples of ants and fungi from throughout the tropics.
