Abstract:The responses of periphyton to enrichment with nitrogen and phosphorus have been investigated in shallow lakes with low macrophyte biomass, but less is known about shallow lakes dominated by submerged plants. We examined the biomass and species composition of periphyton in 12 mesocosms dominated by Vallisneria natans (Lour.) Hara and subjected to different nitrogen and phosphorus enrichment regimes. Periphyton biomass measured as Chlorophyll a (Chl a) was higher in the nitrogenenriched treatment relative to th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
