In ant nervous systems, gene expression may drive rescue behavior
Why do some ants help nestmates in distress while others don't?
Why do some ants help nestmates in distress while others don't?
The short version
- A research team from Johannes Gutenberg University Mainz (JGU) and Tel Aviv University addressed this question in a new study.
- The researchers examined worker ants of the species Cataglyphis niger, some of which had shown rescue behavior while others had not.
- The results, recently published in the Journal of Experimental Biology, suggest that the key difference lies not in body size, morphology or the animals' energy reserves, but in gene activity in the nervous system.
What happened
This article has been reviewed according to Science X's editorial process and policies . A worker ant was restrained on the floor of a sand-lined test chamber.
Why it matters
Individual ants from the same colony were then released into the chamber.
