台湾海峡南部夏季微型浮游动物对不同色素类群浮游植物的摄食压力
Grazing impact of microzooplankton on different pigment groups of phytoplankton in the south Taiwan Strait in summer
摘要
Abstract
Pigment-based growth rates of phytoplankton and mortality rates due to microzooplankton grazing were estimated using a dilution method combined with high-performance liquid chromatography (HPLC) pigment analysis at four different stations in the south Taiwan Strait in July 2005. The growth rates and mortality rates of taxon-specific pigment groups of phytoplankton were 0.52~1.34d-1 and 0.25~1.10 d-1 respectively and the grazing impact of microzooplankton on the standing stocks and primary productions of taxon-specific pigment groups were 22%~66% and 40%~l 51%, respectively. According to the g/k ratio analysis, the net growth rates of the larger phytoplankton groups (ditoms and dinoflagellates) were higher than those of smaller groups (cyanobacteria, cryp-tophytes and prymnesiophytes), suggesting that the smaller phytoplanktons were more readily controlled by microzooplankton grazing.关键词
