A bloom of loricate choanoflagellates was recorded for the first time in the Ross Sea polynya during the austral summer 2017. Both individual cells and uncommon large-size colonies (200 μm length) represent the 42-55% of the total plankton community (i.e. specimens from 5 to 150 μm length). Choanoflagellates serve as a link between low and mid trophic levels since they prey on bacteria and in turn are ingested by zooplankton. This twofold role and the unusual abundance recorded in the Antarctic ecosystem may have relevant but still unknown effects on food web structure and dynamics in that area.
罗斯海冰间湖在 2017 年南半球夏季首次出现有鞘鞭毛虫水华。无论是单个细胞还是不常见的大型群体（长 200μm），均占浮游生物群落总数的 42-55%（即 5-150μm 长度的标本）。有鞘鞭毛虫在低营养级和中营养级之间起到了纽带作用，因为它们以细菌为食，反过来又被浮游动物所摄食。这种双重作用以及在南极生态系统中记录到的异常丰富度，可能对该地区的食物网结构和动态产生相关但仍未知的影响。
