Figure 2.
Top: dorsal view of a stag beetle jaw, with lines on the location of the slices through the male jaw for which Ix, Iy and J were calculated. The arrows show the range of slices that were used to calculate the local buckling moment. Bottom: example of six micro-CT slices on which the cross section of the exoskeleton was determined (depicted in blue). The dorsal (D), ventral (V), lateral (outer jaw side, L) and medial (inner jaw side, M) side of the jaw are shown on the first slice. The scale bar indicates 1 mm. (Online version in colour.)
