Fig. 7. Respiratory and kinematic parameters associated with lunge frequency. (A) Foraging dives that involved more lunges required longer dive durations (MnA, r²=0.77, P<0.001; MnB, r²=0.65, P<0.001) and (B) more bottom time (MnA, r²=0.83, P<0.001; MnB, r²=0.77, P<0.001). (C) A significant correlation was found between the number of lunges executed per dive and the number of post-dive recovery breaths (MnA, r²=0.83, P<0.001; MnB, r²=0.63, P<0.001). (D) Post-dive surface time increased with lunge frequency (MnA, r²=0.52, P<0.001; MnB, r²=0.43, P<0.001). (E) Lunge frequency was associated with a steeper ascent following the lunge bout (D; MnA, r²=0.73, P<0.001; MnB, r²=0.72, P<0.001) and a steeper descent during the subsequent dive (D; MnA, r²=0.42, P<0.001; MnB, r²=0.66, P<0.001). Black lines, MnB; gray lines, MnA.
