“…This uniformity in the vertical distribution of phytoplankton has emerged as a reliable indicator of the effectiveness of water quality regulation under hydrodynamic conditions. Most related studies have traditionally focused on reporting vertical phytoplankton profiles based on total density (Ryabov et al, 2010;Ikram et al, 2017;Chen et al, 2021;Huang et al, 2022), total biomass (Ji et al, 2017;Xue et al, 2017;Sakharova and Korneva, 2018;Cordero-Bailey et al, 2021;Lu et al, 2023;Radchenko et al, 2023), or species composition (Ryabov et al, 2010;Mojica et al, 2015;Ikram et al, 2017;Sakharova and Korneva, 2018;Chen et al, 2021;Huang et al, 2022;Cui et al, 2023;Lu et al, 2023;Radchenko et al, 2023), with limited attention to diversity (Sakharova and Korneva, 2018;Cui et al, 2023). Diversity is also an important community attribute, and various reviews have concluded that diversity plays a major role in maintaining ecosystem productivity and stability (Cardinale et al, 2012;Tilman et al, 2014).…”
