于2012年11月18日至12月21日,在黄、东海沿从南向北(26~36°N)一个断面24个站采样调查了表层(4 m)砂壳纤毛虫群落。共发现砂壳纤毛虫17属,32种。各站砂壳纤毛虫种丰富度为2~15种,砂壳纤毛虫总丰度为2478~88550个/m3。整个断面优势种为筒状拟铃虫、白领细壳虫、小领细壳虫和钝囊坎虫。巴西拟铃虫仅出现在青岛近岸(24号站),但丰度很高(10960个/m3)。砂壳纤毛虫种类多样性从南向北降低,从近岸向远岸增加,黏着壳的比例在近岸水浅处较多,在水深大于50 m 的站位,透明壳所占比例大大增加。不同种类的砂壳纤毛虫有着不同的分布区域,根据分布区域的不同,可分为南方种,北方种和广布种等。聚类分析结果显示,调查区的砂壳纤毛虫可以分为3个群落。
于2012年11月18日至12月21日,在黃、東海沿從南嚮北(26~36°N)一箇斷麵24箇站採樣調查瞭錶層(4 m)砂殼纖毛蟲群落。共髮現砂殼纖毛蟲17屬,32種。各站砂殼纖毛蟲種豐富度為2~15種,砂殼纖毛蟲總豐度為2478~88550箇/m3。整箇斷麵優勢種為筒狀擬鈴蟲、白領細殼蟲、小領細殼蟲和鈍囊坎蟲。巴西擬鈴蟲僅齣現在青島近岸(24號站),但豐度很高(10960箇/m3)。砂殼纖毛蟲種類多樣性從南嚮北降低,從近岸嚮遠岸增加,黏著殼的比例在近岸水淺處較多,在水深大于50 m 的站位,透明殼所佔比例大大增加。不同種類的砂殼纖毛蟲有著不同的分佈區域,根據分佈區域的不同,可分為南方種,北方種和廣佈種等。聚類分析結果顯示,調查區的砂殼纖毛蟲可以分為3箇群落。

The tintinnid species richness and abundance in surface waters (4 m depth) of Yellow Sea and East China Sea (26~36°N) were investigated at 24 stations during 18 November to 21 December in 2012. Totally 32 species in 17 genera were found. The species richness of tintinnids in each station ranged from 2 to 15. The tintinnid abundance ranged from 2 478 to 88 550 ind./m3. The dominant species included Tintinnopsis tubulosoides, Stenosemella nivalis, Stenosemella parvicollis and Ascampbelliella retusa. Tintinnopsis brasiliensis only appeared in station 24 but had a high abundance (10 960 ind./m3). The tintinnid species richness decreased from south to north, increased from nearshore water to offshore area. The proportion of agglutinated loricae was much higher in shallow coastal water, while the proportion of hyaline loricae increased when the water depth was more than 50 m. Tintinnids could be divided into south species, north species and widespread species. Three communities were identified by cluster analysis.
