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.
