Abstract: The activity patterns of 4 sables (1 Female, 3 Males) with radio collars were researched in Daxinganling Mountains, Northeast China from 1991 to 1996. There sults showed that sables were nocturnal in spring and winter, diurnal in summer and autumn. There were differences for activity patterns of sables between spring and summer (F = 4.499; df = 1, 22,23; P = 0.045), between spring and autumn (F =7.039; df = 1, 22, 23 ; P =0.015). Percentage of activity of sables was different in different seasons: 38.29 % in summer; 36.61% in autumn; 27.94 % in winter and 17.53% in spring. There was not obvious relationship between activity pattern and temperature change in spring and winter (P>0.05), but there was a clearrelationship in summer and autumn (P< 0.05). There were some differencesfor activity patterns of individuals among different seasons. Differences existed for activity patterns of F1 between spring and summer (t =2.2550; df =22; P = 0.0175), and between spring and autumn (t = 2.9290; df =22; P = 3.884 E–03). Between spring and summer, there was difference for activity patterns of M1 (t = –2.0121; df = 22; P = 0.0283).
