Figure 1  Computed slopes (95% confidence interval) from ordinary least squares (OLS; dashed line) and standard major axis (SMA; solid line) regression of body mass (g) against pronotum length (mm; both variables log-transformed) in (A) Gryllus texensis (bSMA = 2.642 [2.439–2.862], bOLS = 2.20 [1.988–2.411]) and (B) Acheta domesticus (b SMA = 2.542 [2.245–2.878], b OLS = 1.857 [1.540–2.173]). OLS regression significantly underestimated the relationship between body mass and body size in both species (see text).
