Study Notes
Ant Surgery
- Florida carpenter ants perform life-saving "surgeries" on injured nestmates. This behavior has never been observed in other non-human species.
- These ants are native to the southern United States and live in rotting wood.
- Unlike some other ants, Florida carpenter ants lack antimicrobial glands.
- Researchers at the University of Würzburg injured ants' legs and exposed them to bacteria.
Surgical Procedures
- Ants with femur injuries (upper leg) received amputations.
- This involved multiple ants working together for at least 40 minutes to remove the entire leg, and resulted in a 90% survival rate for treated ants.
- Ants with tibia injuries (lower leg) received cleanings to remove the bacteria.
- This simple action saved 75% of the injured ants. Isolated ants with the same injuries had substantially lower survival rates.
Treatment Decisions
- The ants' decision to amputate or simply clean the wound appears linked to the flow of hemolymph (the ant equivalent of blood).
- Femurs have more muscle tissue to slow hemolymph flow, allowing time for amputations. Tibias have less muscle tissue, thus faster infection spread, leading to a simple cleaning.
Research Significance
- The study highlights an advanced medical system of social behavior in ants.
- The study suggests other ant species may also exhibit similar behaviors.
- The research was published in Current Biology in July 2024.
