冬季海南岛五个海湾浮游植物光合色素分布的比较研究
Comparative study on the distribution of phytoplankton pigments in five bays of Hainan Island
摘要
Abstract
Based on data from an ecological investigation in December 2010, in this study, we identified phyto-plankton marker pigments and their functional groups using high-performance liquid chromatography (HPLC)–CHEMTAX analytical techniques in five bays along the coast of Hainan Island, including Haikou Bay (Haikou City), Chengmai Bay (Chengmai City), Yangpu-xinying Bay (Yangpu City), Xincun Bay (Lingshui city), and Dadonghai (Sanya city). We identified seventeen phytoplankton pigments and determined fucoxanthin and chlorophylla to be the two major pigments, with an average concentration of 0.410 and 0.278μg/L, respectively. Based on their diagnostic pigments, we determined the presence of diatoms, dinoflagellates, cyanobacteria, prasi-nophytes, and cryptophytes. Using CHEMTAX software, we confirmed that the phytoplankton community mainly comprised diatoms, cryptophytes, and prasinophytes. Although diatoms were the most dominant algal group in all the bays studied, we found that cryptophytes in the north of the island contained more chlorophylla than those in the south. The redundancy analysis results suggest that the ways in which phytoplankton are influenced by envi-ronmental factors differ for different phytoplanktons: haptophytes, chrysophytes, and cyanobacteria are positively correlated with water temperature and salinity and negatively correlated with silicate; diatoms are also positively correlated with water temperature and salinity but negatively correlated with dissolved inorganic nitrogen (DIN), silicate, and phosphate; dinoflagellates and chlorophytes are positively correlated with DIN and phosphate but have no obvious correlation with other factors; cryptophytes and prasinophytes are positively correlated with silicate and strongly negatively correlated with water temperature and salinity.关键词
