Abstract Cyanobacterial blooms increasingly threaten vital freshwater ecosystems, with harmful impacts exacerbated by climate change and eutrophication. Despite extensive research on temperature nutrient effects, our predictive capacity remains limited. We propose that this limitation stems from insufficient understanding of how biotic interactions modify cyanobacterial responses to abiotic conditions. Using five years daily monitoring data a eutrophic lake state-space reconstruction modelling, we show co-occurring plankton species fundamentally reshape the realised niche bloom-forming cyanobacteria. Biotic shift thresholds up 13°C phosphorus requirements over 20 μg/L—effects substantial enough determine whether environmental conditions support or prevent in Microcystis Dolichospermum . Grazing inhibits bloom formation across taxa, while facilitation other phytoplankton may allow at unexpectedly low temperatures phosphate concentrations. These findings address fundamental gap—how shape niches natural systems—while offering practical insights for management. By integrating into programs models, can improve forecasting accuracy develop targeted interventions complement traditional control approaches. parallel recent advances ecology suggesting role mediating species’ change.
