Study Notes

Ant "Surgeries"

Florida carpenter ants perform life-saving surgeries on injured nestmates.
This behavior is unique in the animal kingdom.
The ants are native to the southern United States and inhabit rotting wood.
They lack specialized antimicrobial glands.

Surgical Procedures

Researchers injured ants' legs (femur or tibia) and exposed them to a germ.
The ants were divided. Some remained isolated, others returned to their colonies.
Nest-mates performed cleaning and different treatments.
Femur injuries were surgically amputated (taking at least 40 minutes and involving several ants). This led to a 90% survival rate.
Tibia wounds were cleaned with a lick, resulting in 75% survival.
Isolated ants fared much worse, with only 40% (femur) and 10% (tibia) survival rates.

Biological Explanation

The decision of treatment (amputation or cleaning) is linked to hemolymph flow (ant blood).
Femur injuries have more muscle tissue to slow down hemolymph flow, slowing bacteria spread, enabling amputation.
Tibia injuries have less muscle, allowing faster bacterial spread, thus quicker cleaning.
The ants can diagnose and choose the appropriate treatment to heal according to the severity of the wound.

Research Context

Research conducted by Dr. Erik Frank and colleagues at the University of Würzburg.
Published in Current Biology on July 2, 2024.
Future studies will explore similar behaviors in other ant species.
