摘要:

Wheel‐running activity of ten red squirrels,Tamiasciurus hudsonicus, was monitored to determine how temperature and light‐dark cycles affect (1) the number of days required for entrainment; and (2) the phasing, amount and form of wheel‐running activity. The squirrels were individually housed at either a constant temperature of 20 ± 4°C or a temperature cycle of 6.5 ± 2 to 35 ± 2°C. A 12: 12 (207: 0 lx) light‐dark cycle was supplied by an incandescent bulb.
