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]

Core Viewpoint - The application of environmental DNA technology in monitoring the population and ecological status of the endangered bird species, the crested ibis, represents a significant advancement in wildlife conservation efforts in China [4][9]. Group 1: Environmental DNA Technology - Environmental DNA technology is likened to a "detective" that can identify the presence of crested ibises through trace DNA found in the air [6]. - This technology allows for monitoring without the need to capture animals, enhancing the ability to track the population and distribution of crested ibises [9]. - The research team has developed a targeted monitoring technique based on DNA molecules to detect crested ibis DNA from mixed samples [7]. Group 2: Data Collection and Analysis - The research team has collected genomic data from over three cities, covering different ages, sexes, and geographical populations of crested ibises, providing a "golden standard" for future environmental DNA comparisons [10]. - The samples collected are sent to the Shaanxi Environmental DNA Biological Monitoring Laboratory for analysis [7]. Group 3: Conservation Efforts - The initiative aligns with the theme of "Beautiful China, I Take the Lead" for World Environment Day 2025, promoting public engagement in environmental conservation [1]. - The establishment of a crested ibis gene bank is crucial for identifying and confirming the presence of the species through DNA comparison [6].
