| 摘 要： | 20世纪60年代起,人们发现了许多有关桡足类摄食纤毛虫的直接或间接的证据。20世纪70年代,有人在实验室内培养纤毛虫并开展桡足类对其清滤率的研究,结果表明桡足类对纤毛虫的清滤率为0.1—58.1mL/(ind.·h)。桡足类对纤毛虫的摄食方式有多种,包括伏击摄食和通过游泳过滤海水中的纤毛虫等。有的纤毛虫有逃避摄食的行为。20世纪80年代末,自然状况下桡足类群体对自然饵料中纤毛虫的摄食得到了研究,结果表明桡足类对纤毛虫的清滤率多数情况下低于40mL/(ind.·h)。实验室内和自然海区的研究都表明,与浮游植物相比,桡足类倾向于选择摄食纤毛虫。根据现场测定的清滤率和桡足类丰度估计自然海区桡足类对纤毛虫的摄食压力的大部分研究结果表明,桡足类群体对纤毛虫生物量的摄食压力大约为每天5%。这些自然海区的研究多集中在近岸区域,需要加强对大洋浮游桡足类摄食纤毛虫的研究。

| Abstract: | Abstract: From the 1960s, direct or indirect evidences indicated that marine planktonic-copepods ingest ciliates. In 1970s, clearance rates on ciliates were studied in laboratory, and were revealed between 0.1 and 58.1 ml copepod-1 h-1 in most cases. Different copepods have different ways to graze on ciliates, including ambush feeding and suspension feeding. Some ciliates have predator-deterrent strategies such as jumping. Studies on copepods predation on the ciliates in situ began in 1980s. Those studies showed that the clearance rates were below 40 ml copepod-1 h-1. Copepods clearance rates on ciliates were higher than that on phytoplankton, which suggested that copepods may feed selectively on ciliates. The grazing pressure can be estimated by the clearance rates and copepod abundance in situ. Grazing pressure was about 5% per day in most cases. Most of previous studies were conducted in coastal areas or in laboratory. Copepod grazing on ciliates in the oligotrophic oceanic waters is still a knowledge gap. |
