Cyanobacterial blooms in oligotrophic lakes: Shifting the high?nutrient paradigm

Freshwater cyanobacterial blooms have become ubiquitous, posing major threats to ecological and public health. Decades of research focused on understanding drivers these with a primary focus eutrophic systems; however, also occur in oligotrophic systems, but received far less attention, resulting gap our overall. In this review, we explore evidence freshwater systems provide explanations for those occurrences. We show that through their unique physiological adaptations, cyanobacteria are able thrive under wide range environmental conditions, including low-nutrient waterbodies. contend fully understand blooms, thereby mitigate manage them, must expand inquiries consider along the trophic gradient, not solely thus shifting high-nutrient paradigm trophic-gradient paradigm.
