捕风捉“鹮”解码空气里的DNA密码 生态保护开启前所未有全新视角

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].
