Variation of phytoplankton communities and their driving factors along a disturbed temperate river-to-sea ecosystem

Ecological Indicators (2020)

Shasha Zhang Hangzhou Xu Yanfang Zhang Yizhen Li Jielin Wei

Phytoplankton, as an important primary producer in rivers, greatly affects an aquatic ecosystem's function and biodiversity. However, the effect of human activities on phytoplankton community composition remains largely unstudied in rivers. Herein a typical temperate river, Xiaoqing River in the north of China, was the target to investigate the phytoplankton distribution and regime along stretches subject to different human disturbances. Other than in the wetland located in a tributary of the river, which had Cyanophyta as the dominant phylum, Bacillariophyta overwhelmingly predominated across the sampling sites. Notably, the main genus was Fragilaria in the source region of the river, while Cyclotella dominated along the trunk of the river, and the main species shifted from Cyclotella gamma Sovereign to Cyclotella meneghiniana Kützing when the river entered the sea. Phytoplankton community structures in the source region were affected to some extent by DO and pH, and in the human activity areas were mainly influenced by nitrogen, phosphorus, and CODMn. Human interference led to a decrease in diatom density by increasing the concentration of nutrients and organic matter. Furthermore, algal diversity was higher and density was lower in the disturbed areas than in the catchment areas, in accordance with the intermediate disturbance hypothesis. It was also found that human activities more obviously affected the abundant than rare phytoplankton communities.

Seasonal pattern of cyanobacteria community and its relationship with environmental factors: a case study in Luoma Lake, East China

Desalination and Water Treatment (2015)

Ying Ren Yuanshu Liu Wenrong Hu Daping Hao Haiyan Pei

Luoma Lake is located on the east route of the South-to-North Water Diversion Project, and it is a potential source of drinking water. From March 2011 to May 2013, the spatio-temporal distribution variation of cyanobacteria community associated with environmental factors was comprehensively investigated based on a monthly sampling. A total of 27 cyanobacteria species belonging to 14 genera were identified, and the most predominant cyanobacteria genus was Pseudanabaena, not the usual bloom-forming genera such as Microcystis and Anabaena. The cyanobacteria abundance at all the sampling sites exhibited similar spatio-temporal distribution variation, and the cyanobacteria abundance ranged over seven orders of magnitude from the undetectable level to 3.9 × 107 cells/L. Redundancy analysis and Pearson correlation analysis were applied to analyze the relationship between species and environment variables. The results suggested there was a positive correlation between cyanobacteria abundance and water temperature and ammonium concentration, while that between cyanobacteria abundance and dissolved oxygen concentration was negative. In addition, other environmental factors like precipitation and water turbulence could affect the cyanobacteria community distribution. Cyanobacterial blooms might not occur in Luoma Lake, with the predominant cyanobacteria genus being Pseudanabaena and water quality improved owing to the implementation of the water diversion project.

Phytoplankton community structure and environmental factors in a newly built reservoir, Shandong Province

Journal of Lake Sciences (2019)

SUN Wenxiu WU Daoji Haiyan Pei Jielin Wei ZHANG Shasha

基于山东某新建水库中2014年4月-2017年12月的浮游藻类和水质监测结果，研究了藻类群落结构特征，采用非度量多维尺度分析了各年份不同季节藻类群落结构的相似性，利用冗余分析探究了藻类群落结构和环境因子的关系.结果表明：尖针杆藻（Synedra acus）、湖泊伪鱼腥藻（Pseudanabaena limnetica）和小球藻（Chlorella vulgaris）为此水库的主要优势藻种.水库藻类群落结构的季节演替不稳定，冬、春季多以硅藻和绿藻占优势，不同年份夏、秋季藻类结构差异较大，蓝藻和硅藻在夏、秋季存在一定的竞争优势.该水库于2013年底开始启用，由于水体环境的波动，藻类群落结构有所变化，整体上是由蓝藻-绿藻-硅藻向硅藻-绿藻-蓝藻变化.水库浮游藻类生长主要受到氮盐和高锰酸盐指数影响，但不同年份的主要环境影响因子存在一定差异.;Based on the results of phytoplankton and water quality monitoring in a new reservoir in Shandong Province from March 2014 to December 2017, the composition, density and diversity of phytoplankton were clarified. Non-metric multidimensional scaling was used to analyze the difference of phytoplankton community structure in different years and seasons. The relationship between phytoplankton community structure and environmental impact factors was explored by redundancy analysis. The results showed that Synedra acus, Pseudanabaena limnetica and Chlorella vulgaris were dominant algae species in this reservoir. The seasonal succession of the phytoplankton community structure in the reservoir was not stable. In winter and spring, Bacillariophyta and Cryptophyta were dominant, but phytoplankton community in summer and autumn were quite different in different years and Bacillariophyta competed with Cyanophyta in these two seasons. The reservoir started to activate at the end of 2013,due to fluctuations in the water environment, the community structure changed by the time. But the phytoplankton community structure of the reservoir was generally changed from Cyanophyta-Cryptophyta-Bacillariophyta to Bacillariophyta-Cryptophyta-Cyanophyta. The growth of phytoplankton in this reservoir was mainly affected by nitrogen and COD_Mn, however, main environmental factors were different in different years.

Phytoplankton Functional Groups Variation and Influencing Factors in a Shallow Temperate Lake

Water Environment Research (2018)

Chang Tian Daping Hao Haiyan Pei Martina A. Doblin Ying Ren

The present study was carried out in Luoma Lake, a shallow lake in temperate eastern China. Based on a two-year study, the dynamics of phytoplankton functional groups and influencing factors were analyzed. A total of 178 taxa were identified and sorted into 20 codons, according to the phytoplankton functional group classification. In order to find the environmental factors driving phytoplankton variations, fifteen groups were analyzed in detail using redundancy analysis. Groups P (Fragilaria crotonensis), X2 (Chlamydomonas globosa, C. microsphaera and Chroomonas acuta), and MP (Navicula rotaeana) were dominant during low temperature periods, whereas groups X2, S1 (Pseudanabaena limnetica), and W1 (Euglena sp.) were dominant during high temperature periods. Water temperature, total phosphorus, and ammonium were the significant driving factors explaining phytoplankton succession. Furthermore, total phosphorus and ammonium could be broadly used in risk management for potential algal blooms in Luoma Lake.
