Generic Comparisons:
In both Pogonomyrmex and Pheidole , the sexual size ratio
is a significant predictor of the worker size ratio, once controlling
for phylogeny (Pogonomyrmex : F1,8 = 5.421, P =
0.048, R2 = 0.33, Pheidole :
F1,15 = 20.77, P = 0.0004, R2 =
0.55)(Fig. 4 inset). The gyne to worker size ratio is also a significant
predictor of the worker size ratio in both genera – to a greater extent
than the sexual size ratio is (Pogonomyrmex : F1,8= 9.283, P = 0.016, R2 = 0.48, Pheidole :
F1,15 = 70.23, P << 0.0001,
R2 = 0.81).
