All other measurements were not significantly different ( p > 0.05), although horn length approached significance (t = 1.98, p = 0.055).

Based on simple correlations of force versus time for each beetle, it was found that 8 of the 21 beetles tested showed a pattern of reduction in force over time (see the slight downward trend in Figure 2A ), 3 showed no positive or negative trend ( Figure 2B ), and 10 showed a trend of increasing force over time ( Figure 2C ).
