Fig. 3. Summary of wingbeat frequency (fw) data. (A) Low-speed
data. For each species, the mean values ± S.D. of the data at maximum
range velocity (Vmr) are presented. The linear regression
curve may be used to estimate fw at
Vmr for all species. (B) High-speed data. For each
species, the mean value ± S.D. of the data (V>6
ms-1) are presented. The linear regression curve may be used to
estimate fw for all species flying at high speeds. Mp,
Mormopterus planiceps, Nts/w, the southwestern population of
Nyctophilus timoriensis and Nl, Noctilio leporinus.
