We investigated dissolved organic matter (DOM) metabolism by employing plug-flow biofilm reactors and ultra– high resolution mass spectrometry of DOM isolated by C 18 extraction in two forested stream ecosystems, a low DOM tropical stream sampled at baseflow and a higher DOM temperate stream sampled during a storm. On passage through the bioreactors, DOM(More)
