Figure 4.

Polar graphics representing averaged time (in hh:mm) when minimum and maximum VO₂ (A,B, respectively), RER (C,D), and EE (E,F) were expressed over a 24 h period. Female mouse lemurs are shown as circles, and male as triangles. CTL animals are in ligth gray, CR in dark gray. Each experimental group is represented on its own concentric circle: RM (CR males), CM (CTL males), RF (CR females) and CF (CTL females). Time shift is represented by a dashed line for each individual. The shaded phase between 17:00 and 3:00 is the dark phase of the day, when the lights are off.
