Two feedback mechanisms involved in the control of leaf fragment size in leaf-cutting ants.
Römer D, Exl R, Roces F. Römer D, et al. J Exp Biol. 2023 Jun 15;226(12):jeb244246. doi: 10.1242/jeb.244246. Epub 2023 Jun 22. J Exp Biol. 2023. PMID: 37348454 Free PMC article.
When cutting, workers anchor their hind legs on the leaf edge and rotate, removing approximately semicircular fragments. Workers show behavioural plasticity and modify their leg extension while holding onto the leaf edge depending on, for instance, leaf toughness, cutting …
