四川山鹧鸪Arborophila rufipectus是我国特有的珍稀濒危雉科Phasianidae鸟类。以四川老君山国家级自然保护区和四川马鞍山自然保护区为研究区域,基于2020-2022年红外相机的监测数据,采用非参数核密度估计方法对两地四川山鹧鸪种群的日活动节律进行了比较研究。结果显示:老君山种群在繁殖季的日活动节律为多峰型,非繁殖季为双峰型;而马鞍山种群的日活动节律均为双峰型。但2个种群的活动模式差异未达到显著性水平。这表明,四川山鹧鸪的日活动节律兼具保守性和可塑性,丰富了该物种的基础生态学资料。
A Comparative Study on the Daily Activity Rhythm of Arborophila rufipectus
Sichuan partridge(Arborophila rufipectus)is a rare and endangered Phasianidae species endemic to China.The Laojunshan National Nature Reserve and Ma'anshan Nature Reserve are the important habitats for A.rufipectus.In this study,the daily activity rhythms of A.rufipectus at the two sites were compared using non-parametric kernel density es-timation methods based on the infrared cameras from 2020 to 2022.The results showed that the daily activity rhythm of the Laojunshan population was multimodal during the breeding season,while it was bimodal during the non-breeding season.In contrast,the Ma'anshan population exhibited a bimodal pattern throughout the year.The activity patterns of the two populations did not show significant differences.This study reveals that the daily activity rhythms of A.rufipectus exhibit both conservatism and plasticity,and thus enriches the basic ecological knowledge of this species.
