Siberian roe deer Capreolus pygargus is an herbivorous species widely distributed in the northeastern and northern regions of China.It is one of the dominant species in the western Liaoning region.From January 2022 to June 2023,we selected 4 survey sites in western Liaoning and conducted a study on Siberian roe deer based on infrared cam-era monitoring.A total of 116 camera points were set up using a 2 km × 2 km grid method,resulting in 57 995 camera days of infrared monitoring data.Among these,97 camera points captured images of Siberian roe deer,yielding 5 254 in-dependent and valid photos of Siberian roe deer,with 5 058 of these allowing for sex identification.We assessed the rela-tive abundance of the local Siberian roe deer population and analyzed the seasonal variations in their clustering patterns using the Relative Abundance Index(RAI).Additionally,we examined the daily activity rhythm of roe deer using Ker-nel-density estimation.Our study revealed that forest type,altitude,and human interference intensity significantly affect-ed the RAI of Siberian roe deer.Siberian roe deer had 5 cluster types:solitary individuals constituted 92.84％of all inde-pendent detections,followed by female clusters at 4.05％,and the seasonal variation in cluster types was regular and co-incide with changes in reproductive states such as embryonic diapause.There were significant differences in the crepus-cular activity patterns of Siberian roe deer,as evidenced by the more pronounced bimodal pattern observed in females,the peak activity time in the cold season being delayed compared to the warm season,and the greater impact of seasonal variations on female Siberian roe deer.In summary,this study explored the spatio-temporal activity patterns of Siberian roe deer in western Liaoning,the impacts of forest type,elevation,and human disturbance intensity on their relative abundance,as well as the variations in clustering patterns and daily activity rhythm in different sex and season,and prompted targeted conservation recommendations.The research findings contribute to the existing ecological data on Si-berian roe deer,providing support for studying its population structure,developmental mechanisms,and other related as-pects.Furthermore,the study provides valuable insights for the conservation and management of Siberian roe deer and its habitats in western Liaoning.
