Abstract:
From September 2022 to October 2023,infrared cameras were used to study the daily activity rhythm of the Silver Pheasant(
Lophura nycthemera) in the Liangyeshan National Nature Reserve, Fujian, as well as its response to three types of human disturbances—human activities, grazing, and domestic animals—and their seasonal variations.During the survey period, a total of 180 grid points were set up, accumulating 60901 camera days and obtaining 13384 independent valid photos of Silver Pheasants and 2990 independent valid photos of human disturbances.The results showed that significant human disturbances occurred in the reserve during both the breeding and non-breeding seasons, with grazing disturbances being consistently high throughout the year.The activity peaks of Silver Pheasants in both the breeding and non-breeding seasons were concentrated in the early morning(6∶00—8∶00) and late afternoon(17∶00—18∶00),effectively avoiding the peak hours of human disturbances during the day.Moreover, the activity patterns of Silver Pheasants exhibited a high degree of temporal overlap with overall human disturbances, grazing, and domestic animals in both seasons, but they showed a clear avoidance of direct human activities.This suggests that Silver Pheasants can adjust their activity timing to evade human disturbances, thereby enhancing their population fitness.These findings provide valuable data for understanding the survival strategies of wildlife and contribute to the effective conservation of this species.
