| 摘 要： | 冰藻是南北极海冰生物群落中最主要的组成部分,通过固定和输出碳、吸收养分、生产释放氧气和有机化合物,推动高纬度生态系统的生物地球化学循环,在南北极海洋生态系统中发挥着重要作用。从宏观到微观综述了近年来在海冰栖息环境特征、冰藻种类组成和群落结构、冰藻对极端环境的适应机制以及气候变化对海冰环境和冰藻的影响等方面的研究进展,并以黑暗、寒冷和高盐为主要特征重点讨论了冰藻对海冰环境的生理和分子适应机制。提出在气候变化条件下,应进一步研究探索极地海冰环境基线、冰藻生物多样性组成和变化、冰藻代谢生理对环境的应对机制以及海冰生物之间的相互作用,以增进对当前和未来海冰生态系统和生物地球化学循环的理解。

| Abstract: | Ice alage is the main component of polar sea-ice biomes plays an important roles in the ecosystem of the polar area by fixing and exporting carbon,absorbing nutrients,producing and releasing oxygen and organic compounds,and fueling the biogeochemical cycle of the high latitude ecosystem.In this paper,the research progress on the characteristics of sea-ice habitats,the species composition and community structure of ice algae,the adaptation of ice algae to extreme sea-ice environment,and the impact of climate change on sea-ice ecosystem were reviewed at the macro and micro scales.The physiological and molecular adaptation mechanisms of ice algc to dark winters,freezing temperatures and high salinity were discussed.Under climate change conditions,the exploration of the polar sea ice environmental baseline,the investigation of biodiversity of the ice algae and its physiological adaption to the enviroment,and the study of interactions among the sea-ice microorganisms,will improve our understanding of current and future sea-ice ecosystems and biogeochemical cycles. |
