Abstract
In order to reveal the activity rhythm of black bears,a total of 93 infrared cameras were set from October 2021 to October 2022,in 48 transect lines in Huayang Area of Changqing National Na-ture Reserve,Shaanxi Province.The results showed that(1)black bear moved independently in 38 transects,with an altitude range of 1 500-2 500 m.The transects were concentrated in Baiyangping,Yangjiagou and Shanshuping.The main active forest types were broad—leaved forest and mixed broad—leaved forest.The main companion species were takins(Budorcas taxicolor),wild boar(Sus scro-fa),and muntjac(Muntiacus reevesi);(2)the daily activity rhythm of black bear was diurnal,with a bimodal pattern.The activity peaks were distributed at 8:00 to 14:00 and 16:00 to 19:00,with 9:00 being the most active.;(3)the research on seasonal activity rhythm of black bear found that summer was the most frequent,followed by spring and autumn,and winter was almost inactive,and only winter and summer had significant differences in activity frequency(p＜0.05).关键词
