| Abstract: | To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across the Mediterranean, Continental, and Boreal climatic zones of the European continent. Multilinear regression models tested on this snapshot of mostly eutrophic lakes (median total phos-phorus [TP]=0.06 and total nitrogen [TN]=0.7 mg L1), and its subsets (2 depth types and 3 climatic zones), show that light climate and stratification strength were the most significant explanatory variables for chloro-phylla(Chla) variance. TN was a significant predictor for phytoplankton biomass for shallow and continental lakes, while TP never appeared as an explanatory variable, suggesting that under high TP, light, which partially controls stratification strength, becomes limiting for phytoplankton development. Mediterranean lakes were the warmest yet most weakly stratified and had significantly less Chlathan Boreal lakes, where the temperature anomaly from the long-term average, during a summer heatwave was the highest (+4C) and showed a signifi-cant, exponential relationship with stratification strength. This European survey represents a summer snapshotof phytoplankton biomass and its drivers, and lends support that light and stratification metrics, which are bothaffected by climate change, are better predictors for phytoplankton biomass in nutrient-rich lakes than nutrient concentrations and surface temperature. |
