Microcystis, a key genus of bloom-forming cyanobacteria in freshwater ecosystems, has garnered significant research interest due to its species diversity and population dynamics. This study investigated the water profiles Microcystis populations at six stations Nanwan Reservoir (Xinyang, China) throughout 2022 elucidate morphological characteristics analyze density patterns, identify environmental factors influencing The reservoir was classified as mesotrophic during most period. Seven common were identified, including M. botrys, smithii, wesenbergii, firma, novacekii, aeruginosa, suspected be flos-aquae. spatial temporal distribution analyses revealed bimodal fluctuation densities, with monthly occurrence across except August. highest density, 1.71 × 107 cells/L, recorded May, while lower densities observed from July September.
