Fig. 2. Relationship between body mass m and either body weight-specific
vertical force production (filled circles) or muscle weight-specific vertical
force production (open circles) for eleven species of orchid bee. Regressions
as follows: OLS,
Fvert/mg=2.06–0.244m,
r2=0.25, P=0.117 (NS);
Fvert/mmusg=6.22–1.10m,
r2=0.39, P=0.04; RMA,
Fvert/mg=2.15–0.487m,
99% CI for slope: -0.95, -0.03;
Fvert/mmusg=6.46–1.75m,
99% CI for slope: -2.82, -0.73. Allometric exponents are given in
Table 4. NS, not
significant.
