为揭示同域分布的红腹锦鸡(Chrysolophus pictus)和红腹角雉(Tragopan temminckii)在活动节律上的异同及其在人为干扰下的变化,本研究利用2017-2020 年长时红外相机监测数据,运用核密度分析方法,建立重叠模型对两种雉类的日活动节律进行了研究.结果表明:(1)两种雉类均以晨昏活动为主,与繁殖季(Δ=0.874,P>0.05)和多雨季(Δ=0.869,P>0.05)相比,非繁殖季(Δ=0.862,P>0.05)和少雨季(Δ=0.914,P>0.05)的活动节律重叠系数较高,但活动高峰并不相同;(2)红腹锦鸡对人类活动(Δ=0.787,P<0.05)和家畜(Δ=0.831,P<0.05)两种人为干扰类型都表现出较明显的规避行为,而红腹角雉对家养动物的规避程度较小(Δ=0.878,P>0.05).可见,同域分布的这两种雉类尽管活动节律重叠较大,但仍在活动节律上存在季节性差异,且应对人为干扰的响应亦有不同.本研究可为进一步探究两种雉类的行为生态和物种共存提供基础依据.
Comparison on Activity Rhymes Between Two Sympatric Pheasants Chrysolophus pictus and Tragopan temminckii and Their Response to Human Disturbance
In order to reveal the similarities and differences in the activity rhythms of the related species of Chrysolophus pictus and Tragopan temminckii in the same domain,and their changes under human interference,this study used the long-term infrared camera monitoring data from 2017 to 2020 and studied the diurnal rhythms of C.pictus and T.temminckii by nuclear density analysis method and overlapping model.Results showed that:(1)Both pheasants were mainly active in the morning and dusk.Comparing with the breeding season(Δ=0.874,P>0.05)and rainy season(Δ=Compared with 0.869,P>0.05),the overlap coefficients of activity rhythms of two pheasants in non-breeding season(Δ=0.862,P>0.05)and less rainy season(Δ=0.914,P>0.05)were relatively high,but the activity peaks were not the same.(2)Chrysolophus pictus showed obvious avoidance behavior in human activities(Δ=0.787,P<0.05)and livestock(Δ=0.831,P<0.05),while T.temminckii had a smaller degree of avoidance of domestic animals(Δ=0.878,P>0.05).Although the activity rhythms of the two pheasants distributed in the same domain overlap greatly,there were still seasonal differences in activity rhythms,and the response to human disturbance was also different.This study can provide a basis for further exploring the behavioral ecology and species coexistence of the two pheasants.
