Biomechanics of cutting: sharpness, wear sensitivity, and the scaling of cutting forces in leaf-cutter ant mandibles
F. Pueffel, O. K. Walthaus, V. Kang, D. Labonte
The paper measures cutting forces in leaf-cutter ant mandibles to show that wear, not size, primarily affects cutting efficiency, with smaller ants being more vulnerable to wear-related force increases.
