Cyanobacterial blooms under CO2(aq)-limited conditions in karst reservoirs diminish the synergy of pollution reduction and carbon sequestration via the biological carbon pump

Key Points

• Cyanobacterial blooms are reducing the synergy of pollution reduction and carbon sequestration in karst reservoirs.
• Key evidence shows significant impacts of CO2(aq)-limited conditions on biological responses within various karst environments.
• Analysis includes both biological carbon pump dynamics and nutrient cycling in carbon-limited waters, assessing ecological balance.
• Highlighting a need for further research on long-term ecological impacts, particularly concerning karst reservoir management.
