由于海水变暖,热带鱼类正沿着澳大利亚海岸向南迁徙,而ENNA揭示了隐藏物种的移动。 Tropical fish are migrating south along Australia’s coast due to warming waters, with eDNA revealing hidden species movements.

由于气候变化, 澳大利亚东海岸的鱼类正在迁移到较冷的水域, Fish are moving into cooler waters along Australia’s east coast due to climate change, with tropical species increasingly appearing in temperate zones. 一项新研究将传统的直观调查和环境DNA(eDNA)分析从2 000公里海岸线的海水样本中得出,揭示了视觉方法常常遗漏的外科鱼类、鹦鹉鱼、豪猪鱼和松鼠等物种的隐性迁徙。 A new study combining traditional visual surveys and environmental DNA (eDNA) analysis from seawater samples across 2,000 kilometers of coastline revealed hidden migrations of species like surgeonfish, parrotfish, porcupinefish, and squirrelfish that visual methods often miss. 虽然视觉调查更好地检测到温带物种,但电子DNA提供了生物多样性变化、捕捉隐秘、夜间或稀有鱼类的更完整的图象。 While visual surveys better detected temperate species, eDNA provided a more complete picture of biodiversity shifts, capturing cryptic, nocturnal, or rare fish. 调查结果显示,电子DNA补充了传统方法,为跟踪海洋生态系统中气候驱动的变化提供了强有力的工具。 The findings show that eDNA complements traditional methods, offering a powerful tool to track climate-driven changes in marine ecosystems.
