科廷美里水样验出绿鬣蜥DNA 仍待确认活体情况
-
美里科廷大学校园一个水样验出非原生普通绿鬣蜥的环境DNA，但研究人员强调，这还不能确认校园现时有多少活体，甚至不能单凭结果认定仍有活体留在当地。
10月15日公布的发现，来自2026年科廷全球BioBlitz生物调查。美里、珀斯及新加坡三地共有逾100名学生与研究人员参与，整体调查分析2万6572条不同DNA序列，识别572个物种；这些数字涵盖调查整体，不是美里校区单独的物种数量。
环境DNA技术采集生物遗留在水体等环境中的遗传物质，因此不必先看见动物，也可能找到物种线索。不过，绿鬣蜥DNA来自哪里、是否对应仍在校园活动的个体，还须进一步追查。
对砂拉越的生态监测，这次成果展示了水样筛查的用途，也说明筛查讯号与确认族群是两回事。公众可通过科廷的eDNA Viewer查看调查结果；校方计划逐步扩展至全球六个校区，累积长期比较资料。
