The ecological responses of browning are a concomitant effect of climate change and nutrient status. Results from long-term, large-scale lake experiments have been variable, showing both strong synergistic effects  and no significant effects of browning on plankton community food webs . Browning has driven a shift from auto- to heterotrophic/mixotrophic-based production  and supports heterotrophic metabolism of the bacterial community . Browning may also accelerate primary production through the input of nutrients associated with dissolved organic matter  in nutrient-poor lakes and increase cyanobacteria, which cope better with low light intensities  and toxin levels . However, the synergistic impacts of browning and climate change on aquatic communities depends on regional precipitation patterns
