在北极海冰下发现的氮固化微生物可能会随着冰层的减少而改变海洋生态系统。 Nitrogen-fixing microbes found under Arctic sea ice could reshape marine ecosystems as ice declines.

科学家们已经发现了固氮微生物,叫做非水生微生物,在北极海冰下面的北极海冰下,以前认为这些区域太冷和暗,无法维系生命。 Scientists have discovered nitrogen-fixing microbes, called non-cyanobacterial diazotrophs, beneath Arctic sea ice in regions previously thought too cold and dark to support life. 这些生物在中北极和欧亚北极发现,具有将大气氮转化为可用形式的遗传特征,有可能促进藻类生长、碳吸收和海洋食物网。 Found in the Central and Eurasian Arctic, these organisms possess genetic traits for converting atmospheric nitrogen into a usable form, potentially boosting algal growth, carbon absorption, and marine food webs. 虽然活性固氮还没有被直接观测到 但它们在冰边附近的丰度 表明它们具有重要的生态作用 Though active nitrogen fixation hasn't been directly observed, their abundance near ice edges suggests a significant ecological role. 随着北极冰层的减少,这些微生物可能会越来越普遍,改变生态系统的动态。 As Arctic ice declines, these microbes may become more prevalent, altering ecosystem dynamics. 研究人员说,目前的气候模型必须说明这一以前被忽视的过程,以改进全球预测。 Researchers say current climate models must account for this previously overlooked process to improve global predictions.
