- Interactions between members of the microbial loop in an estuary dominated by microzooplankton grazing (2009-2011)
- Description:
- Abstract:
- Quantifying the linkages between primary production and higher trophic levels is necessary to understand why particular regions can support high fisheries production. Modified dilution experiments were employed to characterize microbial communities in surface waters at four sites from within a bay to the shelf in the northern Gulf of Mexico (nGOM). Inshore surface waters were more variable than shelf surface waters due to the strong influence of river discharge. Phytoplankton (Chl a) and prokaryote biomass were both significantly higher inshore than on the shelf, with phytoplankton significantly higher than prokaryotes inshore. Virus and heterotrophic nanoflagellate abundances, however, did not differ between inshore and shelf waters. Samples were amended with nutrients (N + P) to examine the impact of nutrient limitation. Prokaryotes were nutrient limited in 14 (28%) of the experiments, while phytoplankton were nutrient limitated in 26 (52%) of the experiments. When phytoplankton were nutrient limited, prokaryote growth rates were significantly altered. A similar impact on phytoplankton growth rates occurred when prokaryotes were nutrient limited, suggesting that the two groups are in competition for resources. Grazing was detected in the majority of experiments, while viral lysis was only detected in 24% of phytoplankton and 12% of prokaryote experiments. Growth and grazing rates for both phytoplankton and prokaryotes were tightly coupled inshore and on the shelf, with significantly more phytoplankton and prokaryotes grazed inshore (average = 106% and 75%, respectively) than on the shelf (average = 55% and 57%). These findings indicate that surface waters across the estuary are highly productive, with microzooplankton grazing transferring the majority of the microbial production to higher trophic levels.
- Purpose:
- These experiments were designed to determine the relative roles of grazing and viral lysis on the microbial communities in Mobile Bay, AL.

- Process_Description:
- Collection: Samples (26L) were collected from surface waters from four FOCAL stations (MB, DI, CP and T35), filtered through 150 um Nitex screen and kept in the dark until returned to the DISL. Physical parameters were obtained from CTD casts. Samples were processed in low light for nutrients, abundance of protists, prokaryotes and viruses and the concentration of chlorophyll a. Modified dilution experiments were carried out to determine the growth, grazing and viral lysis rates for phytoplankton and prokaryotes.
- Process_Date:
- Unknown
- Process_Step:
- Process_Description:
- Nutrients were measured using a Skalar + autoanalyzer. Samples were collected after filtration through a 0.7 um glass fiber filter. Samples were stored frozen prior to processing.
- Process_Date:
- Unknown
- Process_Step:
- Process_Description:
- Abundances: Phytoplankton was measured using chlorophyll a. Water was filtered through a 25 mm 0.7 um glass fiber filter and frozen immediately in liquid nitrogen, then stored at -86C until processing. Pigments were extracted in acetone/DMSO and determined using a Turner Fluorometer.
Samples for protists, prokaryotes and viruses were fixed in 0.5% EM grade glutaraldehyde and flash frozen in liquid nitrogen. Samples were stored at -86C until processing. DAPI slides were prepared to determine protist numbers using epifluorescences microscopy while prokaryotes and viruses were counted using flow cytometry.

- Process_Step:
- Process_Description:
- Modified Dilution Experiments: To determine rates of growth, grazing and viral lysis, water was filtered through 0.7 um glass fiber filter and a 0.2 um Durapore filter. Virus free water was produced by passing the filtered water through a tangential flow filtration cartridge (30kDa).
Two parallel dilution series were produced in triplicate. One with 0.2 um filtered water and one with virus free water. Samples were collected for chlorophyll a and prokaryote abundance at t=0 and t=24. Prokaryotes were also sampled at t=12. 1 L bottles were incubated in floating cages in the water to allow for ambient light and temperature conditions. Growth, grazing and viral lysis rates were determined from changes in the abundance of pigments or cells over time using linear regressions.
