“…On the other hand, phytoplankton community as a biological key component of the aquatic food web, initiates the aquatic food chain by serving as food to primary consumers (Bordj and Saadi, 2022), and its structure and dynamics have crucial effects on aquatic ecosystem stability (Wang et al, 2021). Hence, phytoplankton are e cient indicators of nutrient load variety and also effective in evaluating responses to environmental stressors due to their quick responses to water quality, hydrology and climate change (Domingues et al, 2008).…”

Although phytoplankton are well known as robust bioindicators to aquatic environments, their indicating functions based on different community parameters remain to be understood. In order to ltering effective bioindicators to aquatic ecosystems, four phytoplankton community parameters including species richness (SR), total biomass (SBP), functional groups (FGBP) and size-fractionated chlorophyll-a (SC) were demonstrated and tested in a subtropical arti cial lake with ecological restoration in South China. Our results indicated that all the above four parameters exhibited high sensitivity to environmental variations and illustrated distinct aspects of indicating functions to aquatic environments due to their individual biological characteristics. Based on FGBP, both spatial and temporal differences in phytoplankton community could be identi ed; SR and SBP only classi ed the spatial and temporal distributions, respectively; while SC could distinguish the sewage outfalls from other sites. In terms of ecological management, two parameters (SR and FGBP) could distinguish the restored waters from untreated environments as non-point source pollution, and another parameter SC could indicate the sewage outfalls as point source pollution. Therefore, the combination of the above two categories of phytoplankton community parameters could make the strongest indicating functions. Our study provided greater insight into indicating functions of phytoplankton community parameters in an ecological restored lake and enabled better managements in such arti cial lakes.
