There is widespread evidence that aquatic consumers use terrestrial resources depending on the features of surrounding catchments.
Over the last several decades, many lakes globally have increased in dissolved organic carbon (DOC), calling into question how lake functions may respond to increasing DOC. Unfortunately, our basis for making predictions is limited spatial surveys, modeling, and laboratory experiments, which not accurately capture important whole-ecosystem processes. In this article, we present data on metabolic physiochemical responses of a multiyear experimental whole-lake increase DOC concentration....
The observed pattern of lake browning, or increased terrestrial dissolved organic carbon (DOC) concentration, across the northern hemisphere has amplified importance understanding how consumer productivity varies with DOC concentration. Results from comparative studies suggest these concentrations may reduce crustacean zooplankton due to reductions in resource quality and volume suitable habitat. Although spatial comparisons provide an expectation for response as concentration increases, we...
