摘要

气候变化对海洋生态系统构成重大威胁,其影响遍及全球。气候变化对海洋生态系统的一个主要影响是水温上升,导致海洋生物栖息地向北扩展。Herdmania momus 是一种海鞘,原产于热带和亚热带地区,后被引入朝鲜半岛。在这项研究中,我们考察了 2016 年至 2022 年期间朝鲜半岛东南沿海的海鞘栖息地。我们发现,在整个调查区域都观察到了H. momus的栖息地,2016年在釜山、2021年在蔚山、2022年在庆州(最北端的地点)确认了栖息地。观察到的栖息趋势表明地理范围迅速扩大,比之前的预测提前了约 79 年。这些观测结果表明,海洋生物正在经历比先前预测更迅速的地理扩张。这些意想不到的发现应为政府制定积极措施和战略以管理气候变化对海洋生态系统的影响提供参考。

The distribution of the red-throated ascidian Herdmania momus shifts northwards in association with ocean warming in the Korean Peninsula

Climate change poses a major threat to marine ecosystems, with its effects felt worldwide. A major effect of climate change on marine ecosystems is the rise in water temperature, leading to a northward expansion of habitats for marine organisms. Herdmania momus, a species of ascidians (sea squirts), originally found in tropical and subtropical regions, was introduced to the Korean Peninsula. In this study, we examined the habitat of H. momus along the southeastern coast of the Korean Peninsula between 2016 and 2022. We found that H. momus settlements were observed across the entire survey area, with confirmed habitation in Busan in 2016, Ulsan in 2021, and Gyeongju (the northernmost location) in 2022. The observed habitation trend indicates a rapid geographical expansion, occurring approximately 79 years earlier than previously predicted. These observations demonstrate that marine organisms are undergoing a more rapid geographical expansion than previously projected. These unexpected findings should inform government policies related to proactive measures and strategies for managing the impact of climate change on marine ecosystems.
