| 摘 要： | 运用生态毒理学方法,研究了UV-B辐射条件下褶皱臂尾轮虫(Brachinonus plicatilis)对6株海洋微藻:小球藻(Chlorella sp.、绿色巴夫藻(Pauloua uiridis)、扁藻(Tetraselmis chuii)、球等鞭金藻8701(Isochrysis galbana Park 8701)、牟氏角毛藻(Chaetoceros muelleri Lermumerman)和小新月菱形藻(Nitzschia clostertum)的摄食.结果表明:UV-B辐射增强对褶皱臂尾轮虫的摄食有显著的抑制作用.与对照组相比,褶皱臂尾轮虫对每一种饵料单胞藻的滤水率和摄食率都表现出,随UV-B辐射剂量的增大而显著减小(P＜0.5).而且对每一种饵料单胞藻的滤水率和摄食率是不相同的,这说明褶皱臂尾轮虫对饵料单胞藻是有选择性的.

| Abstract: | The feeding of the rotifer Brachionus plicatilis with six strains of marine microalgae(Chlorella sp.,Pauloua uiridis,Tetraselmis chuii,Isochrysis galbana Park 8701,Chaetoceros muelleri Lermumerman and Nitzschia clostertum) were evaluated under the UV-B radiation treatment using the ecotoxicology methods.The results showed that the feeding of the rotifer Brachionus plicatilis was inhibited significantly by UV-B radiation treatment(P<0.05),Compared with control,the filtering rate and feeding rate of the rotifer Brachionus plicatilis were significantly lower(P<0.05)with increasing dose of UV-B radiation.In addition,the filtering rate and feeding rate of the rotifer Brachionus plicatilis were different with every strain of the marine microalgae.This result showed that the rotifer Brachionus plicatilis was selectivity with the six strains of the marine microalgae. |
