Fig 4. Day and night time activity at CNR, JAX and KI.

Fig 4

Box plots (cages) showing global activity (ordinate) of the five cages during day time (A, D, G) and night-time (B, E, H) across 11–13 weeks for each day of the cage-change cycle (abscissa; 0 being day of cage-change). Weeks at each site are presented separately for each day of the cage-change cycle. Asterisk denote day of cage-change while double asterisk indicates day of weighing. At all three sites there were significant variation in day-time activity between weekdays (p<0.001) and also between weeks at each site (p<0.02–0.001), however, the week-to-week variation in activity did not co-vary with the variation of activity between weekday (weekday*week p>0.05).
