Highlights

  • Macrophytes reduce phytoplankton biomass and increase water clarity in turbid tropical lakes in a density-dependent manner.
  • High-density macrophyte treatments shift phytoplankton communities from turbid water-adapted filamentous cyanobacteria to clear water-adapted green algae and cryptophytes.
  • Emergent and submerged macrophytes reduced phytoplankton biomass and distinctly altered taxonomic and functional composition.

Highlights

  • We identified macrophytes species for restoration of tropical reservoirs.
  • All six species reduced cyanobacteria and increased cryptomonads at high density.
  • Ludwigia adscendens and Persicaria barbata reduced chlorophyll a concentrations.
  • Effective densities were found to be above 0.40 dry weight g/L.

Highlights

  • We evaluated the effects of emergent macrophytes species on the phytoplankton community of a eutrophic tropical reservoir with cyanobacterial dominance
  • We conducted ex-situ mesocosm experiments.
  • Emergent macrophytes did not reduce phytoplankton biomass but some altered community composition.
