| 内容記述 | Historically, most studies about the geographic distribution of zooplankton in the Southern Ocean have been focused on the macro-sized zooplankton (2–20 mm), such as the Antarctic krill and larger-sized copepods. On the other hand, despite the high abundance and biomass, the distribution patterns of micro- (20–200 μm) and meso-sized (200 μm–2 mm) zooplankton communities are little understood. In this study, we investigated the distribution patterns of larger micro-zooplankton (100–200 μm) and meso-zooplankton communities in the seasonal ice zone in the Cosmonaut Sea near Syowa Station and examined the effects of environmental factors and water properties on these communities. The investigation was based on samples collected with 100 μm mesh nets, which are appropriate to estimate the quantitative abundance and community structure of micro- and meso-zooplankton species between 1983 and 1995. Cluster analysis of the samples revealed that the distribution of macro-zooplankton species was influenced by the temperature and salinity of ocean fronts. Among the meso-zooplankton, cyclopoid and small calanoid copepods tended to be ubiquitously distributed. However, among the micro-zooplankton, the distributions of foraminiferans and tintinnids were associated with sea ice extent. The distribution of micro- and meso-zooplankton communities could be used to estimate the impact of environmental changes on the marine ecosystem in the Southern Ocean. | |||||||||||||||

| 内容記述 | 昭和基地沖Cosmonaut海の季節海氷域におけるマイクロ動物プランクトン (Micro-sized zooplankton: 20-200 μm) とメソ動物プランクトン (Meso-sized zooplankton: 200-2,000 μm) を含む動物プランクトン群集の分布様式を明らかにし、環境要因が与える影響について検証した。キクロプス目やカラヌス目カイアシ類といったメソ動物プランクトンは、調査海域において現存量で優占し、また普遍的に出現し、その分布は一様であった。一方で、マイクロ動物プランクトンである有孔虫や繊毛虫は、南北で分布様式が異なり、環境要因の中で海氷の張り出しが一因であることが示唆された。 | |||||||||||||||
