| 摘要: |
| 于2014年12月至2015年1月在热带西太平洋沿台湾南部到雅浦海山一个断面和雅浦海山海区研究了浮游纤毛虫丰度和生物量的垂直分布。浮游纤毛虫丰度变化范围为0-635ind./L, 生物量范围为0-1.53μgC/L, 丰度和生物量高值分布于200m以浅, 其中, 砂壳纤毛虫丰度为0-45ind./L, 占总纤毛虫丰度的比例在0-14.62%之间。浮游纤毛虫丰度垂直分布均呈现"双峰型"模式: 在表层和叶绿素极大值层(DCM)出现高值。共鉴定出砂壳纤毛虫33属76种。雅浦海山海区优势种为纤弱细瓮虫、卢氏真铃虫、管状真铃虫、膨大波膜虫, 西太平洋海区优势种为纤弱细瓮虫、海勒斯真铃虫、酒杯类管虫、尖锐号角虫。有些种类分布在100m以浅, 有的种类分布在100m以深, 说明砂壳纤毛虫在100m水深左右种类发生变化。 |

| Abstract: |
| We investigated the full-depth abundance and biomass of planktonic ciliates in the Yapu Seamount area and along a transect from south Taiwan to Yapu Seamount in Western Pacific from December 2014 to January 2015. Abundance and biomass ranged from 0 to 635ind./L, and from 0 to 1.53μg C/L, respectively. High abundance and biomass were found in the upper 200 m. The abundance of tintinnid ranged from 0 to 45ind/L, taking 0-14.62% of the total ciliates abundance in all stations across all layers in 0-200m. The vertical distribution of planktonic ciliates abundance showed "bimodal-peak" pattern in this area. Ciliates abundance was high in the surface and the deep chlorophyll maximum (DCM) layers. In taxonomy, 76 tintinnid species of 33 genera were identified. The dominant species in the Yapu Seamount were Steenstrupiella gracilis, Eutintinnus lusus-undae, Eutintinnus tubulosus, and Undella turgida; and in the Western Pacific were Steenstrupiella gracilis, Eutintinnus haslae, Dadayiella ganymedes, and Salpingella acμminata. Some species occupied in waters shallower than 100m and others in waters deeper than 100 m. Therefore, the depth 100m was the border where tintinnid species composition changed. |
