    Paired O₂–CO₂ measurements provide emergent insights into aquatic ecosystem function
    (Wiley, 2020) Vachon, Dominic; Sadro, Steven; Bogard, Matthew J.; Lapierre, Jean-Francois; Baulch, Helen M.; Rusak, James A.; Denfeld, Blaize A.; Laas, Alo; Klaus, Marcus; Karlsson, Jan; Weyhenmeyer, Gesa A.; del Giorgio, Paul A.
    Metabolic stoichiometry predicts that dissolved oxygen (O2 ) and carbon dioxide (CO2 ) in aquatic ecosystems should covary inversely; however, field observations often diverge from theoretical expectations. Here, we propose a suite of metrics describing this O 2 and CO2 decoupling and introduce a conceptual framework for interpreting these metrics within aquatic ecosys- tems. Within this framework, we interpret cross-system patterns of high-frequency O 2 and CO2 measurements in 11 northern lakes and extract emergent insights into the metabolic behavior and the simultaneous roles of chemical and physical forcing in shaping ecosystem processes. This approach leverages the power of high-frequency paired O 2–CO2 measurements, and yields a novel, integrative aquatic system typology which can also be applicable more broadly to streams and rivers, wetlands and marine systems.

    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 L 1 ), 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- phyll a (Chl a) 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 Chl a than Boreal lakes, where the temperature anomaly from the long-term average, during a summer heatwave was the highest (+4 C) and showed a signifi- cant, exponential relationship with stratification strength. This European survey represents a summer snapshot of phytoplankton biomass and its drivers, and lends support that light and stratification metrics, which are both affected by climate change, are better predictors for phytoplankton biomass in nutrient-rich lakes than nutrient concentrations and surface temperature.
