Fig. 4. Stride frequency, stride length, breath frequency and tidal volume versus speed for Terrapene carolina (N=54 locomotor bouts from one individual). (A) Stride frequency (open circles; y=6.47x+0.3, r²=0.79, P<0.0001) and stride length (filled squares; y=0.843x+0.017, r²=0.851, P<0.0001) versus speed. (B) Tidal volume (filled circles; y=10.9x+0.611, r²=0.08, P<0.0377) and breath frequency (open squares; y= -6.36x+1.62, r²=0.19, P<0.001) versus speed.
