这项发表在英国学术期刊《自然-气候变化》上的研究说,观测显示相关海域表层水的铁含量下降、温 度上升,这可能是浮游植物发生变化的原因,因为硅藻更需要铁,而定鞭藻和隐藻对铁的依赖性较低, 能更好地适应变化的环境。 新华社悉尼7月31日电(记者梁有昶 齐紫剑)一个国际团队的新研究显示,南极海域食物网基础正在 发生重大变化,位于食物网底部的硅藻不断减少。这种变化可能会影响整个南极生态系统,并改变海洋 调节气候的能力。 研究人员表示,南极海域生态系统受到气候变化的影响,又可能通过反馈机制加剧气候变化,对两者之 间的相互作用需要进一步加强研究。(完) 由澳大利亚政府资助的"澳大利亚南极计划伙伴关系"组织近日发表声明说,来自丹麦、新西兰、澳大利 亚、西班牙和美国的研究人员分析了1997年至2023年间,在南极洲周围海洋中收集的14824个浮游植物 样本集。结果显示,硅藻在不断减少,逐渐被定鞭藻和隐藻取代。 据介绍,硅藻是磷虾喜欢吃的食物,磷虾又是企鹅、海豹和须鲸等动物的食物。定鞭藻和隐藻更容易被 樽海鞘吃掉,而樽海鞘对于其他动物来说是营养较差的食物。因此,硅藻减少可能会影响整个南极生态 系统。 此外,上述藻类能通过光合作用 ...
