Ted Schultz surveys the gigantic mound of a higher agricultural-ant colony in the seasonally dry Brazilian Cerrado (savanna) near Brasilia in 2009. Higher fungus-farming ant colonies and agricultural behaviors are comparably larger-scale and more complex than the colonies of lower fungus-farming ants.
