Fig. 7. Scaling of kinematic, morphological and muscle performance data in Phasianidae. (A) Total pectoralis muscle mass (Mp) versus body mass (Mb); (B) wing stroke frequency (n) versus body mass; (C) relative downstroke duration (DS%) versus body mass; (D) pectoralis muscle strain (
) versus body mass; (E) average shortening velocity (V) versus body mass. Data are from blue-breasted quail (Mb=43.6 g; this study), northern bobwhite (Mb=199.5 g), chukar (Mb=491.5 g), ring-necked pheasant (Mb=943.4 g) and wild turkey (Mb=5275 g) (Tobalske and Dial, 2000). Relationships that are significantly different from zero are denoted by *(P<0.05) and **(P<0.01).
