| 摘 要： | 在不同斜生栅藻(Scenedesmus obliquus)密度(1.0×10~6、2.0×10~6个细胞/m L和4.0×10~6个细胞/m L)下,研究了不同浓度的(0、1、10、100、1000μg/L和5000μg/L)布洛芬对萼花臂尾轮虫(Brachionus calyciflorus)生命表统计学参数的影响。结果表明,与各藻密度下的对照组相比,当藻密度为1.0×106个细胞/m L时,100—5000μg/L布洛芬处理组中轮虫的生命期望和平均寿命显著缩短,100μg/L布洛芬处理组中轮虫的世代时间显著缩短,1.0μg/L布洛芬处理组中轮虫的净生殖率显著提高,10—5000μg/L布洛芬处理组中轮虫的后代混交率显著提高。当藻密度为2.0×10~6个细胞/mL时,10—5000μg/L布洛芬处理组中轮虫的生命期望和平均寿命显著缩短,1000μg/L和5000μg/L布洛芬处理组中轮虫的世代时间显著缩短,1、10、1000μg/L和5000μg/L布洛芬处理组中轮虫的种群内禀增长率显著提高,1μg/L和1000μg/L布洛芬处理组中轮虫的后代混交率显著提高。当藻密度为4.0×10~6个细胞/mL时,10—5000μg/L布洛芬处理组中轮虫的生命期望、平均寿命和世代时间显著缩短。藻密度对轮虫的世代时间、净生殖率和种群内禀增长率有显著性影响(P0.05),布洛芬浓度对轮虫的生命期望、平均寿命、世代时间、净生殖率和种群内禀增长率有显著性影响(P0.05),藻密度和布洛芬浓度的交互作用对轮虫的生命期望、平均寿命和后代混交率有显著性影响(P0.05)。在实验设置的布洛芬浓度范围内,2.0×10~6个细胞/m L藻密度下,轮虫的生命期望、平均寿命和世代时间与布洛芬浓度之间均具有显著的剂量—效应关系(P0.05); 4.0×10~6个细胞/m L藻密度下,轮虫的生命期望、平均寿命和净生殖率与布洛芬浓度之间均具有显著的剂量—效应关系(P0.05)。
