Abstract

Abstract

Microzooplankton communities in the northern South China Sea (18°00'-22°00'N,114°00'-116°00'E) were investigated during August and September in 2014. With the analysis by Uterm hl method,a total of 142 taxa which belong to 44 genera of 2 phyla were identified. Tintinnid (28 genera and 78 species were identified) accounted for 54.93% of the species,41.55% were oligotrichs (14 genera and 59 species). Dominant taxa included Strombidium paracalkinsi,Strombidium sulcatum,Strombidium wilberti and the nauplii. Abundance of microzooplankton ranged from 11.43 ind/L to 959.35 ind/L,with an average of 264.99 ind/L. Microzooplankton were mainly concentrated at depths 50 m,and decreased gradually bellow 50 m. Microzooplankton in the surface water were mainly concentrated in the Station J5 and Station I1. Shannon-Wiener diversity index of vertical distributions ranged from 0.92 to 4.18,with an average of 2.77. Pielou's evenness index ranged from 0.63 to 1,with an average of 0.87. According to canonical correspondence analysis (CCA),temperature and salinity are important factors of microzooplankton communities. In the time-series stations (J4 and SEATS),the diurnal fluctuation of microzooplankton communities changed lightly in the upper water but more stable in the lower water. Microzooplankton communities temporal changes are generally coincide with chlorophyll a distributions.
