陕西长青自然保护区小麂与毛冠鹿日活动节律研究初报

Daily Activity Rhythms of Muntiacus reevesi and Elaphodus cephalophus Revealed by Infrared-triggered Cameras

为给陕西长青自然保护区制定更科学、合理、经济的动物保护措施提供依据和参考,利用网格化监测方法布设的100多台红外相机2019年4月至2021年4月的监测资料,研究分析了小麂和毛冠鹿日活动节律及两者之间的共存关系。结果显示:小麂和毛冠鹿在日活动中呈现出一定的晨昏活动特征,正午时段小麂有一个活动高峰期,而毛冠鹿选择了躲避较高的温度;小麂和毛冠鹿核密度曲线重叠系数为0.891,活动节律曲线差异显著(P<0.01),二者出现了显著分化,即同一区域内因需求相似而选择了一定程度的避让,以实现彼此共存。

After a two-year continuous detecting from April 2019 to April 2021,with the grid monitoring method used to set 92 infrared-triggered cameras in the field,and by analyzing the collected data with the kernel density estimation,the difference in the daily activity rhythms between the Muntiacus reevesi and the Elaphodus cephalophus in the Changqing National Nature Reserve of Shaanxi Province were compared.The results showed that there was a certain active characteristics at both dawn and dusk between Muntiacus reevesi and Elaphodus cephalophus.Muntiacus reevesi had a peak activity during noon,while Elaphodus cephalophus preferred to avoid the higher temperature.The superposition analysis of the kernel density estimation showed that the overlap coefficient was 0.891,and the activity rhythm curve was significantly different(P<0.01),which further indicated that there was a significant differentiation between these two species.Because of similar needs in the same area,the two choose to avoid a certain degree to achieve coexistence.This result help to understand the behavior patterns and characteristics of beer family,and provide important basic data for further species protection in the Changqing National Nature Reserve.
