California ground squirrels (Spermophilus beecheyi) were kept for 5-7 years at 20°C with excess food. Presence or absence of nests, built from newspapers, was noted semiweekly, The squirrels were weighed semimonthly. Squirrels were kept in small rooms at natural (SB) length of day and at LD 12:12. Nests were built by squirrels in SB from May to January with a minimum in February to April. Squirrels in LD 12:12 ran freely. The date of the minimum building advanced steadily about a month a year. The persistence of rhythms in LD 12:12 conditions shows that building of nests is an endogenous rhythm and properly called circannual. |
