THE INJURY TEST OF MEMORY. “For the mound to serve its respiratory function, the colony must have knowledge, in some form, of how the mound is structured. That the colony has such knowledge is revealed dramatically by the response to mound injury, such as a breach of the mound surface by a soil auger. This initiates an immediate repair program that plugs the damaged mound, usually in less than a day, and often within a few hours of the injury. This is followed by an extended process of remodeling that, over periods that can span years, restores the damaged part of the mound to its form and functionality prior to the injury.”
