紫外辐射对鱼类及水生无脊椎动物影响的研究进展

全球性的气候变化严重地威胁着自然生态环境间的平衡。在影响生态系统功能的诸多因素中,太阳紫外辐射的增强逐渐成为最受关注的全球性环境问题之一。太阳紫外辐射对地球生物的生命过程有着举足轻重的影响。生物体一旦吸收了高能量的紫外辐射,则可对其各种生理过程产生影响,打破内稳态,尤其是紫外辐射对DNA的损伤作用,是诱导一系列生物效应的主要原因。本文综述了近年来与鱼类及水生无脊椎动物有关的紫外辐射研究。从紫外辐射对生物不同发育时期的影响、生物对紫外线响应方式、紫外辐射与其他因素复合影响三个层面进行总结。通过总结紫外辐射对鱼类及水生无脊椎动物的影响,可为预测紫外辐射在水生生态系统中的作用提供助力,为海洋生物对环境变化的生理响应研究提供参考。

Research progress in the influence of ultraviolet radiation on fish and aquatic invertebrates

Global climate change poses a significant threat to the balance of the natural ecological environment. Among the various factors affecting ecosystem function, the increased exposure of solar ultraviolet radiation (UVR) is emerging as a serious global environmental concern. Solar UVR plays a pivotal role in the life processes of organisms on Earth. However, excessive absorption of UVR by organisms can disrupt their physiological processes and homeostasis. Specifically, UVR has a damaging effect on DNA that induces a range of adverse biological effects. This paper reviews recent research on the impact of UVR exposure on fish and aquatic invertebrates, summarizing the findings from three perspectives: the impact of UVR on different developmental stages, the response mechanisms of organisms to UVR, and the combined effects of UVR and other factors. Therefore, understanding the effects of UVR on fish and aquatic invertebrates can improve our understanding of its future role in aquatic ecosystems and provide a reference for studying the physiological response of marine organisms to environmental changes.
