Effects of DOM on benthic algae in northern lakes

<em>Differences in dissolved organic matter among lakes can impact the ecology of benthic primary producers by altering the availability of nutrients (positive relationship with DOM) and light (negative relationship with DOM). While these effects and their interaction has been explored for pelagic algae through field and modeling studies, the effects of DOM on production by benthic algae is less well understood. This dataset represents a field-based experiment to investigate the pattern in benthic algal growth and nutrient limitation along a regional DOM gradient among lakes in Boreal and Arctic Sweden. </em>
