大兴安岭地区紫貂的活动节律

借助无线电遥测技术，对４只紫貂全年的活动节律进行了研究，结果表明，紫貂的活动节律春季和冬季的高峰是在晨昏二个阶段，夏秋二季的活动高峰在白昼。春季总体活动节律与夏季相比有明显差异（Ｆ＝４．４９９，ｄｆ＝１，２２，２３；Ｐ＝０．０４５），春季与秋季的活动节律也有差异（Ｆ＝７．０３９；ｄｆ＝１，２２，２３；Ｐ＝０．０１５）。其总体平均活动强度，春季活动量最小（１７．５３％），夏季最高（３８．２９％），其

ACTIVITY PATTERNS OF SABLES ( MARTES ZIBELLINA ) IN DAXINGANLING MOUNTAINS,CHINA

The activity patterns of 4 sables (1 Female,3 Mal es) with radio collars were researched in Daxinganling Mountains, Northeast C hina from 1991 to 1996. The results showed that sables were nocturnal in spring and winter,diurnal in summer and autumn.There were differences for activity pat terns of sables between spring and summer ( F =4 499; df =1,22,23; p =0 045), between spring and autumn ( F =7 03 9; 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 patte rn and temprature change in spring and winter ( P >0 05), but there was a clear relationship in summer and autumn ( P <0 05). There were some differences for activity patterns of individuals among different seasons. Differences existed for activity patterns of F1 between spring and su mmer ( t =2 255 0; df =22; P =0 017 5), and between spring and autumn ( t =2 929 0; df =22; P =3 884 E-03). Between spring and summer,there was difference for activity patterns of M1 ( t =-2 012 1; df =22; P =0 028 3).
