“…Furthermore, studies have been conducted on the response of phytoplankton communities in the ecosystems of lakes and rivers to water management projects such as lake water diversion. Dai et al quantitatively analyzed the differences in phytoplankton community before and after the implementation of a water diversion project in the Taihu Lake Basin, providing specific insights into the contribution of water diversion projects to the changes in phytoplankton community [ 10 , 11 ], these researches contributed to enhance the ecological benefits and management of water diversion projects. Chen et al studied the driving mechanisms of phytoplankton in urban artificial lakes and identified dissolved oxygen (DO), chlorophyll, and TN as the main driving factors [ 12 ].…”

“…Generally, the main source of lake water is from its inflow rivers, the nutrients loadings of lakes are usually positively correlated with the nutrients inputs from the inflow rivers (Bridgeman et al, 2012; Gao et al, 2021). The water quality status of lake water body is closely related to the inflow rivers, so does the phytoplankton diversity (Bridgeman et al, 2012; Dai et al, 2022). It is essential to explore the discrepancy of phytoplankton diversity between lake and its inflow rivers and the effects of environmental variables on phytoplankton to provide references for assessment and protection of lakes and rivers.…”

Phytoplankton diversity is closely related to environmental variables and has been widely used in ecological health assessment of rivers and lakes. Combining advantages of DNA‐based identification and high‐throughput sequencing technology, environmental DNA (eDNA) metabarcoding permits a new measurement for biodiversity monitoring in aquatic ecosystems. However, it had rarely been used to explore the variability and similarity of phytoplankton diversity between lake and its inflow rivers and the effects of environmental variables on phytoplankton. This study utilized eDNA metabarcoding to investigate the spatial distribution of phytoplankton and the impacts of environmental variables on the phytoplankton diversity in Dianchi Lake (one of the most polluted urban lakes in China) and its main inflow rivers (Panlong River, Baoxiang River, and Chai River). A total of 243 distinct phytoplankton taxa were detected, covering 9 phyla, 30 classes, 84 orders, and 132 families, and the taxonomic richness of rivers was higher than that of Dianchi Lake. Distinct biodiversity patterns (e.g., community structure, dominant taxon, ɑ‐diversity) were exhibited among Dianchi Lake and its three inflow rivers, but similar biodiversity patterns were also observed in Dianchi Lake and the estuarine sites. The patterns of phytoplankton diversity were closely related to environmental variables, which were associated with pollution sources from different anthropogenic activities (e.g., urbanization, water diversion, industrial and agricultural activities). The primary environmental variables correlated with phytoplankton diversity varied in different habitats. The total phosphorus (TP) and chemical oxygen demand (COD) positively correlated with the phytoplankton community structures in Dianchi Lake, whereas negatively correlated in Panlong River and Baoxiang River. The total nitrogen (TN) positively correlated with the phytoplankton community structures in Baoxiang River and Chai River but negatively correlated in Dianchi Lake. Overall, this study provides insights on the phytoplankton diversity monitoring and the conservation of its diversity and healthy management of Dianchi Lake.
