海水和海冰中的海洋微藻为高纬度生态系统提供燃料，并通过碳的固定和输出、营养物质的吸收、氧和有机化合物的产生和释放，推动生物地球化学循环。高纬度海洋环境的特点是低温、黑暗的冬季和强烈的季节性循环。在这种环境中，存在着许多多样和动态的栖息地，特别是与海冰的形成和融化有关的栖息地，以及随着季节变化而变化的独特微藻群落。藻类生理是一个至关重要的组成部分，既响应动态环境，又反过来影响其直接的物理化学环境。随着高纬度海洋进入新的气候环境，对季节性反应的分析可能会为微藻如何应对长期环境变化提供见解。这篇综述讨论了我们对高纬度海洋微藻的生理是如何在极地季节循环中调节的理解的最新进展，重点是冰相关（共生）藻类。特别是，将探索影响更大规模过程的生理学，目的是提高我们对当前和未来生态系统和生物地球化学循环的理解。
Marine microalgae within seawater and sea ice fuel high‐latitude ecosystems and drive biogeochemical cycles through the fixation and export of carbon, uptake of nutrients, and production and release of oxygen and organic compounds. High‐latitude marine environments are characterized by cold temperatures, dark winters and a strong seasonal cycle. Within this environment a number of diverse and dynamic habitats exist, particularly in association with the formation and melt of sea ice, with distinct microalgal communities that transition with the season. Algal physiology is a crucial component, both responding to the dynamic environment and in turn influencing its immediate physicochemical environment. As high‐latitude oceans shift into new climate regimes the analysis of seasonal responses may provide insights into how microalgae will respond to long‐term environmental change. This review discusses recent developments in our understanding of how the physiology of high‐latitude marine microalgae is regulated over a polar seasonal cycle, with a focus on ice‐associated (sympagic) algae. In particular, physiologies that impact larger scale processes will be explored, with an aim to improve our understanding of current and future ecosystems and biogeochemical cycles.
