Cyanobacterial Blooms Increase Functional Diversity of Metazooplankton in a Shallow Eutrophic Lake

Harmful cyanobacterial blooms disrupt aquatic ecosystem processes and biological functions. However, studies focusing on the effect of functional diversity consumers are still insufficient. To examine interactions composition metazooplankton, we investigated variation in metazooplankton their driven variables during bloom non-bloom periods 2020 2021 Lake Xingkai. We found that reduced species but increased biomass, dispersion, evenness. Generalized additive mixed model results revealed cyanobacteria showed different effects biodiversity periods. Variance partitioning analysis indicated cyanobacteria, physicochemical variables, temporal explained 15.93% period 20.27% Notably, more variations than those period. Our suggest significantly impact community metazooplankton. Physicochemical spatiotemporal factors may mask findings improve understanding dynamics responses communities to environmental changes disturbances enhance our ability assess effectiveness restoration eutrophication management.
