Missisquoi Bay (MB) is a temperate eutrophic freshwater lake that frequently experiences toxic Microcystis-dominated cyanobacterial blooms. Non-point sources are responsible for the high concentrations of phosphorus and nitrogen in the bay. This study combined data from environmental parameters, E. coli counts, high-throughput sequencing of 16S rRNA gene(More)
Assessing ammonium (NH4 +) availability in aquatic systems requires accurate concentration and turnover rate data. Water column NH4 + regeneration, potential NH4 + uptake, and nitrogen (N) fixation rates were measured in Missisquoi Bay, Lake Champlain, to help constrain internal N dynamics affecting phytoplankton community structure and cyanobacteria (Cy)(More)
