Relationship between green tide distribution and plankton community in the South Yellow Sea in 2022
摘要
Abstract
This study evaluated the plankton community in surface waters of the South Yellow Sea(119 °E-122.5 °E,34.5 °N-37 °N)in 2022.A high-throughput sequencing technique was used to analyze the characteristics of biological community structure during green tide.Simultaneously,environmental elements were investigated,and the potential relationship between the environment and the distribution of plankton was comprehensively analyzed.The purpose of this study aimed to provide a basis for understanding the ecological effects of green tide in the South Yellow Sea.The results showed that the estimated total wet weight of green tide in the South Yellow Sea in early July 2022,was 7.24 tons,which mainly accumulated near the Shandong coast and Haizhou Bay.Ulva prolifera biomass,phytoplankton,and zooplankton were significantly positively correlated with inorganic phosphate.In the covered area of Ulva prolif-era,phytoplankton and zooplankton had high richness.Dinophyta and Copepoda were the main dominant species,including Neoceratium,unclassified Syndiniales,Obelia,and Penilia.Compared with the area without Ulva prolifera,the dominant species in this area was relatively single,leading to the possibility of secondary disasters.Upon investi-gation the bacterioplankton community,Desulfuromonadia and Gammaproteobacteria were found to be closely related to the Ulva prolifera biomass.Significantly positive and negative correlations were noted between Ulva prolifera biomass and Desulfuromonadia and Gammaproteobacteria,respectively.The correlation analysis revealed that phyto-plankton diversity was mainly affected by total dissolved nitrogen,phosphorus,and dissolved organic nitrogen in the environment.The correlation analysis between Ulva prolifera and environmental factors demonstrated that the occur-rence of green tide could provide suitable environmental conditions for some bacterioplankton.The co-occurrence network of plankton communities showed that the abundance of plankton is high and the relationship is closely com-plex in the area covered by Ulva prolifera during the green tide.Therefore,the green tide of Ulva prolifera has a po-tential impact on the community structure and richness of plankton.关键词
