Epiphyte shading: Its role in resulting depth distribution of submerged aquatic macrophytes

  • Kaj Sand-Jensen


The biomass of epiphytic algae increased more than the biomass of phytoplankton with increased nutrient availability (N, P, Si) in four lakes. Large epiphyte biomasses on the submerged macrophyte,Littorella uniflora, reduce light attenuation more than phytoplankton did. High values of shading by epiphytes correspond with a reduction in the maximum depth penetration ofLittorella by more than 1 meter.
