藻型浅水湖泊小型底栖动物的群落特征及生态地位探讨
COMMUNITY CHARACTERISTICS OF MEIOFAUNA IN AN ALGAE-DOMINATED SHALLOW LAKE, WITH A DISCUSSION ON THE ECOLOGICAL ROLE
-
摘要: 小型底栖动物(Meiofauna)是指分选时能通过0.5 mm或1.0 mm (本研究中指1.0 mm)孔径的网筛, 但被0.042 mm 孔径网筛所阻留的一类底栖生物, 主要指多细胞动物[1,2]。小型底栖动物是鱼、虾和贝等幼体阶段的优质饵料, 在底层食物网能量流动中起着重要作用, 且因种类多、数量大、世代周期短和终身底栖等优点, 开始应用于环境监测[2,3]。
