Phytoplankton assemblages in offshore water in mid-Zhejiang province during the winter of 2014
摘要
Abstract
A total of 97 phytoplankton samples were collected in a multidisciplinary investigation from offshore wa-ters in mid-Zhejiang province (28°43¢–30°02¢N, 121°42¢–126°18¢E) from December 2014 to January 2015. Moreover, the phytoplankton species composition, assemblage structure, and cell abundance of phytoplankton were studied. A total of 163 species belonging to 53 genera of 6 phyla were identified (including uncertain species). The phytoplankton community mainly comprised bacillariophyta and dinophyta. Moreover, in the study area, the phytoplankton commu-nity was divided into four ecological types: a true estuarine component, coastal component, eurythermal and eury-haline marine component, and a high salinity component. of these, the eurythermal and euryhaline marine component was the major ecotype. Dominant phytoplankton species wereOdentella sinensis, Coscinodiscus jonesianus, Thalas-siothrix frauenfeldii.,Coscinodiscus oculus-iridis, Ditylum sol,andChaetoceros lorenzianus. Cell abundance ranged from 0.3×104cells/m3to 61.7×104cells/m3 with an average of 8.8×104cells/m3. The higher values occurred in the area between Sanmen Bay and the Yushan Islands. The average Shannon-Wiener indices of phytoplankton assemblages was 3.36, and according to Pearson correlation analysis, the distribution of phytoplankton cell abundance was positively correlated with phosphate and nitrate but negatively correlated with salinity.关键词
