Abstract:
      Ciliates are important components in planktonic food webs, but our understanding of their community structures in different oceanic water masses is limited. We report pelagic ciliate community characteristics in three seas: the tropical West Pacific, the Bering Sea and the Arctic Ocean. Planktonic ciliate abundance had “bimodal-peak”, “surface-peak” and “DCM (deep chlorophyll a maximum layer)-peak” vertical distribution patterns in the tropical West Pacific, the Bering Sea and the Arctic Ocean, respectively. The abundance proportion of tintinnid to total ciliate in the Bering Sea (42.6%) was higher than both the tropical West Pacific (7.8%) and the Arctic Ocean (2.0%). The abundance proportion of small aloricate ciliates (10–20 μm size-fraction) in the tropical West Pacific was highest in these three seas. The Arctic Ocean had higher abundance proportion of tintinnids in larger LOD (lorica oral diameter) size-class. Proportion of redundant species increased from the Arctic Ocean to the tropical West Pacific. Our result provided useful data to further understand ecology roles of planktonic ciliates in different marine habitats.
中文摘要:
      纤毛虫是浮游食物网的重要组成部分,但是关于其在不同大洋水团中的群落结构资料极少。我们在热带西太平洋、白令海和北冰洋海区中研究了浮游纤毛虫群落特征。热带西太平洋、白令海和北冰洋海区中浮游纤毛虫的垂直分布模式分别为“双峰”、“表层高”和“DCM(叶绿素浓度最大值)层高”型,砂壳纤毛虫丰度占总纤毛虫丰度的百分比中,白令海(42.6%)高于热带西太平洋(7.8%)和北冰洋海区(2.0%)。热带西太平洋海区中小粒级无壳纤毛虫(10-20 μm粒级)丰度占总无壳纤毛虫的丰度比例高于白令海和北冰洋海区。但是太平洋海区中大口径组砂壳纤毛虫丰度比例最高。砂壳纤毛虫冗余度从北冰洋至热带西太平洋海区中呈现递增的趋势。我们的结果为进一步了解浮游纤毛虫在不同的海洋生境中的生态作用提供了基础。
