| 摘 要： | 全球变暖和人为活动不断加剧海洋低氧环境发生的频率和范围,低氧对全球海洋底栖生物群落结构造成重大影响。底栖有孔虫能够广泛适应生存在各种海洋低氧环境中,是极少数能适应低氧环境的真核生物之一,底栖有孔虫对低氧环境的响应及适应机制研究是海洋研究领域的前沿和热点话题,至今仍存在很多谜团。本文总结了不同海洋低氧环境活体底栖有孔虫分布特征、活体底栖有孔虫对人为诱导低氧环境的响应、低氧环境下底栖有孔虫外壳化学组成特征、低氧环境下底栖有孔虫的生存机理,期望为后续推进海洋低氧环境下底栖有孔虫相关研究进一步开展提供参考和借鉴。底栖有孔虫作为古海洋环境重建的重要工具,对我们了解全球海洋低氧环境的历史演化进程具有非常重要的意义。展望未来我们需要进一步加强有孔虫细胞生理学和分子生物学对低氧环境的适应机制研究,从系统发生学上认识真核生物对低氧环境适应的历史演化进程,为利用有孔虫作为工具更好地重建和预测海洋低氧环境变化提供理论依据。

| Abstract: | Global warming and human activities increase the frequency and scope of marine low-oxygen environments, and hypoxia has a significant impact on marine benthic communities. Benthic foraminifera, among a few eukaryotes, can widely adapt to and survive in various marine low-oxygen environments, and the response of benthic foraminifera to hypoxia and the adaptation mechanisms are hot topics in marine research with many unsolved mysteries. This article summarizes the distribution characteristics of living foraminifera in various marine hypoxic environments and their response to artificially induced hypoxic environment, chemical composition characteristics of benthic foraminiferal shells in hypoxic environment, and survival mechanisms of foraminifera in hypoxic environments, seeking to provide a reference for future research on benthic foraminifera under marine hypoxic environment. Benthic foraminifera, as an important tool for the reconstruction of the ancient marine environment, are of great significance to our understanding of the evolutionary history of ocean hypoxia. Looking forward, future researches should focus on cellular, molecular and physiological investigation of the mechanisms of foraminiferal adaptation to hypoxic environment as well as gaining phylogenic insights into the historical evolutionary processes of eukaryotic adaptation to hypoxic environment, so as to provide a theoretical basis for using foraminifera as a tool to better reconstruct and predict changes under hypoxic conditions. |
