Fig. 5. Variation among PGI genotypes in the effects of body mass on running speed for field-collected larvae. Data shown are running speeds for PGI 1-1, 1-4 and 4-4 genotypes (N=74, 87, 24, respectively). Running speed was significantly related to body mass for PGI 1-4 and 4-4 (1-4: y=3.45x+0.17; R2=0.05; F1,85=4.9; P=0.03; 4-4: y=10.03x+0.07; R2=0.33; F1,22=10.7; P=0.003), but not 1-1 genotypes (not significant).
