【省生态环境厅】秦岭羚牛分布监测取得新突破

Core Insights - The research team led by the Shaanxi Provincial Environmental Monitoring Center has successfully developed a qPCR quantitative detection method based on environmental DNA technology for monitoring the distribution of the Qinling takin in the Qinling Mountains [1][2] - The monitoring effort involved 77 sampling points across the province, resulting in the collection of 229 environmental DNA samples, with 50 points successfully detecting the environmental DNA signals of the Qinling takin [1][2] Group 1 - The Qinling takin is a flagship species of the Qinling Mountains in Shaanxi Province and serves as a "living indicator" of the health of high mountain forest ecosystems [1] - The results indicate a concentrated distribution of the Qinling takin in the central region of the Qinling Mountains and the southwestern area adjacent to the Han River, with minimal presence in the Dan River basin and none detected in northern Shaanxi [1] - There is a noted trend of the Qinling takin gradually expanding from the central and western regions of the Qinling Mountains towards the eastern areas, influenced by population migration and human activities [1] Group 2 - The monitoring results provide crucial ecological baseline information for biodiversity and flagship species protection efforts in Shaanxi Province [2] - The study further validates the efficiency and reliability of environmental DNA technology in wildlife monitoring, offering a reliable technical pathway for enhancing the ecological monitoring system in Shaanxi [2] - The application of environmental DNA technology is expected to significantly improve the precision and efficiency of ecological monitoring in Shaanxi, supporting the protection of rare species, health assessments of ecosystems, and dynamic monitoring of biodiversity [2]
