Cyanobacterial blooms present substantial challenges to managers and threaten ecological public health. Although the majority of cyanobacterial bloom research management focuses on factors that control initiation, duration, toxicity, geographical extent, relatively little role loss processes in how these are regulated. Here, we define a process terms population dynamics as any removes cells from population, thereby decelerating or reducing development extent blooms. We review abiotic (e.g., hydraulic flushing oxidative stress/UV light) biotic allelopathic compounds, infections, grazing, resting cells/programmed cell death) known govern loss. found dominant depend several system specific including genera-specific traits, situ physicochemical conditions, microbial, phytoplankton, consumer community composition. also address context discuss perspectives predicting changing climate may directly indirectly affect A deeper understanding their underlying mechanisms help mitigate negative consequences improve current strategies.

Abstract Toxic cyanobacterial blooms have expanded and intensified on a global scale. Although microcystins are known as the most abundant cyanotoxins released during blooms, physiological role of these toxic secondary metabolites has not been fully resolved. Here, we show that microcystin production is important for Microcystis to maintain carbon metabolism under long‐term nitrogen starvation subsequent recovery. Compared in nonmicrocystin‐producing strains, could accumulate more reserves limitation, which survival cells stressful conditions. Transcriptomic analysis revealed genes involved synthesis were significantly up‐regulated at initial recovery phase, indicating their essential strengthening glycogen catabolism fueling Flow cytometry showed compared nontoxic microcystin‐producing exhibited higher rate after prolonged starvation, consistent with dominance species early stage blooms. The close genetic traits between strains suggest strategies observed here might be highly conserved. Our results imply establishes competitive advantage over provides insights into seasonal succession natural populations.
