摘要/Abstract

摘要：

鉴于东太平洋热带海区表层砂壳纤毛虫和其他微型浮游动物的群落结构资料几乎空白, 我们于2013年8月14日至9月18日在夏威夷东南部海区的23个站位采样调查了表层砂壳纤毛虫群落。23个站位共采集到砂壳纤毛虫22属36种, 均为透明壳种类。各站砂壳纤毛虫种丰富度范围为15-21种, 总丰度范围为4,730-23,693个/m³, 生物量范围为9.60-88.61 μg C/m³。本海区主要优势种为镯形囊坎虫(Ascampbelliella armilla)、斯廷细瓮虫(Steenstrupiella steenstrupii)、薄壳真铃虫(Eutintinnus tenuis)和纤弱细瓮虫(Steenstrupiella gracilis), 这4种主要优势种的口径范围不同。

Abstract

The species richness and abundance of tintinnids in the surface waters at 23 stations located in southeast of Hawaii were investigated between 14 August and 18 September 2013. A total of 36 species in 22 genera were identified. All tintinnid species had hyaline loricae. The species richness of tintinnids in each station ranged from 15 to 21. Tintinnid abundance and biomass ranged from 4,730 to 23,693 ind./m³, and from 9.60 to 88.61 μg C/m³, respectively. The top four dominant species were Ascampbelliella armilla, Steenstrupiella steenstrupii, Eutintinnus tenuis and S. gracilis. These top four dominant species were in different lorica oral diameter (LOD) size-classes.
