Understanding the mechanisms driving community structure and dynamics is crucial in the face of escalating climate change, including increasing incidences of extreme weather. Cell size is a master trait of small organisms that is subject to a trade-off between resistance to grazing and competition for resources, and thus holds potential to explain and predict community dynamics in response to disturbances. Here, we aimed at determining whether cell size can explain shifts in phytoplankton communities following changes in nutrient and light conditions resulting from storm-induced inputs of nutrients and colored dissolved organic matter (cDOM) to deep clearwater lakes.

- Lakes around the world are influenced by multiple factors, particularly climate change, resulting in nutrient and humic substance overload during extreme weather, complicating ecological predictions.
- Researchers conducted experiments to study the effects of storm-induced lake browning and nutrient enrichment on phytoplankton, finding that browning inhibits phytoplankton growth and shifts community composition.
- Long-term monitoring data support these experimental findings, revealing that clear-water lakes have lower phosphorus thresholds for cyanobacterial blooms compared to humic lakes, which offers practical management insights for nutrient-rich lakes affected by climate change.
