Phytoplankton Pigment Specific Growth And Losses Due To Microzooplankton Grazing In A Northern Gulf Of Mexico Estuary During Winter/Fall, Amanda M. Mcgehee, Donald G. Redalje
Gulf and Caribbean Research
Microzooplankton dilution grazing experiments were carried out on 6 dates, over a 3 month period at 2 locations in the Bay of St. Louis, MS (BSL) to determine phytoplankton pigment specific growth rates under natural (µ0) and replete (µn) nutrient conditions and microzooplankton grazing. We hypothesized that diatoms would be the largest portion of the phytoplankton composition due to the winter/fall season and that these organisms would have the highest growth/grazing rates. We suspected that river flow from the Jourdan River would adversely affect growth and grazing rates of all phytoplankton classes. Growth rates of 5 …
