Eutrophication

Abstract

Major advances in the scientific understanding of eutrophication and the significant effects of eutrophication have been made over the decades. The effects of eutrophication include increased biomass of freshwater phytoplankton and periphyton; shifts in phytoplankton species composition to taxa that may be toxic or inedible, e. g. bloom-forming cyanobacteria; reduced biodiversity of waterbodies; changes in vascular plant production, biomass, and species composition; reduced water clarity; and decreases in the perceived aesthetic value of the water. Relative abundances of major bacterial and archaeal groups indicate high similarities at the phylum- and class-level groups across eutrophicated lakes. The impact of climate change and greenhouse gases emissions regards to affect and effect of eutrophication leads to various studies. The effect of reducing nitrogen inputs alone for controlling eutrophication by controlling inputs of phosphorus.
