一位香港学者在十多年来首次于本地水域检测到极度濒危物种——黄唇鱼的DNA。这项发现是于去年9月利用环境DNA技术得出的。
岭南大学科学教研组助理教授叶志豪与华南师范大学的王俊杰共同领导了这项研究。他们开发了一种遗传鉴定方法，用于检测海洋环境中残留的黄唇鱼DNA痕迹。
这一珍稀物种的DNA于去年9月在香港西部水域被识别出。此前一个月，约1300条人工繁育的黄唇鱼幼鱼从内地被放流至珠江口。岭南大学表示，这一发现表明部分被放流的鱼类可能已经进入了香港水域。
叶志豪表示：“我们研究团队开发的新型检测技术具有高度灵敏性，如果鱼类曾经过某个区域并留下了极微量的环境DNA，其踪迹就能被准确测定。”环境DNA是指生物体排放到周围环境中的遗传物质。

Australian researchers are using environmental DNA techniques on feces samples to identify suitable habitats for the critically endangered Gilbert's potoroo. The work aims to establish new populations of the marsupial, which numbers fewer than 150 in the wild. The approach could improve translocation efforts after past setbacks including a major bushfire.
Researchers from the University of Hong Kong and Lamma Island residents are restoring seagrass coverage to address a 60 percent decline over two decades and support local green sea turtle populations.

South Korea's Coast Guard seized two Chinese fishing boats near Baengnyeong Island on Saturday for illegal fishing in its waters. One Chinese sailor died during the operation after suffering cardiac arrest.
Scientists have identified a previously unknown genus and species of giant salamander from fossils found in Japan more than two decades ago. The creature, named Limnospondylus ajimuensis, lived about 3.5 million years ago and may have grown to 1.1 meters long.
