October, and March, (b) LD 8:16. n = 4: Note the cessation of activity between September and the middle of December. At the beginning of January, a spontaneous resurgence of activity during the scolophase occurs, which is continuous for the rest of the experiment except for a decline in activity in March. LD 8:16 are summari/ed schematically in relation to the natural photoperiod in Figure 4. At the start of the experi- ment in September, the natural photoperiod was LD 13:1 |. All animals placed under the LD 16:8 photoperiod (Fig. 4a) showed strong, nocturnal activity that continued until March, when the natural photoperiod was once again LD.
