Large seasonal or permanent blooms of green macroalgae (Ulva spp.) are one of the most widespread signs of eutrophication in shallow coastal environments. Macroalgal canopies attenuate light affecting negatively, or even fully inhibiting, microphytobenthic primary production at the sediment surface. In addition, macroalgal photosynthetic and respiratory activities affect the oxygen availability in the water column and the … Continue reading Macroalgal blooms
