Phytoplankton Community Responses to Nutrient Addition in Lake 226, Experimental Lakes Area, Northwestern Ontario [pdf]Paper  abstract   bibtex   
Inclusion of phosphorus in fertilizer added to one of two basins of\na small lake, between which water exchange was greatly reduced by\na vinyl sea-curtain, significantly increased epilimnetic phytoplankton\nbiomass, and altered species composition. Over an 8-year period,\nthe average biomass of phytoplankton in the basin receiving carbon,\nnitrogen, and phosphorus (in ratios of 10:5:1) increased 4 to 8 times\nand the biomass in the basin receiving only carbon and nitrogen (in\nratios of 10:5) increased 2 to 4 times over non-fertilized years.\nThe basin receiving all three nutrients consistently had blooms in\nlate summer which were dominated by nitrogen fixing species of cyanophytes.
