摘要In order to study the effects of latitudinal change in physical and chemical environments on phytoplankton cells, we investigated the early summer phytoplankton biomass, species composition and size-fractioned productivity in surface water from the Java Sea to the South China Sea (from 6 degrees S to 20 degrees N) from 18 May to 27 May 2010. Chlorophyll a (Chl a) concentration decreased latitudinally from 0.18 (similar to 6 degrees S) to 0.05 mu g l(-1) (similar to 10 degrees N). The dominant species, the cyanobacteria Trichodesmium erythraeum, dinoflagellates (e. g. Gyrodinium dominans, Amphidinium carterae and Gonyaulax spp.) and diatoms (e. g. Thalassionema nitzschioides, Rhizosolenia spp. and Chaetoceros spp.) changed to only the dinoflagellate species. Also, the Chl a biomass increased to 0.14 mu g l(-1) towards the end of the survey (similar to 20 degrees N) with the dinoflagellates as the most abundant group. Productivity of phytoplankton assemblages coincided with Chl a concentration, and decreased accordingly from 9.24 +/- 0.71 to 2.87 +/- 0.41 mg C l(-1) day(-1), then increased to 5.45 +/- 1.1 mu g C l(-1) day(-1). Chl a concentration and productivity were significantly correlated (P < 0.05) with microplankton cell abundance, as well as nutrient concentrations, which appeared to exert a strong influence over latitudinal variation in primary production.
