Bacteria counts using DAPI epifluorescence, heterotrophic bacteria production with tritiated Thymidine uptake, and algal energetics and chl a using the PAM fluorometer were determined from each of the water samples. Bacteria counts in Shark River Slough in the freshwater end of the transect revealed highest bacteria numbers upon marsh rewetting after the dry down. The highest overall count of bacteria was found at the most freshwater point adjacent to the perimeter of the water conservation area but only in March of 2001. Peak numbers of bacteria in the saline end of Shark River transect occurred in December and July. There is some evidence that these higher bacteria numbers in the SR transect are associated with higher salinities. Highest bacteria counts along the Taylor slough transect were observed at the mouth of the Taylor River with peak counts in the wet season in October. Bacteria densities also increased from the eastern to western end of the transect in Florida Bay. Heterotrophic bacterial production did not relate closely bacteria numbers and exhibited highest numbers in the dry season. There was no discernible relationship between salinity and bacteria production as seen in bacteria numbers. Monthly observations using PAM fluorometry revealed that brown algae was the greatest contribution to the algal chal a pool and this relationship was consistent across all FCE LTER sites. Converse to the pattern of bacteria abundance along the Shark River transect, there was evidence that algal biomass decreases from freshwater to estuary. In the Shark River, algal energetics increased from marsh to estuary as well as in the panhandle region of the Taylor River transect. From these observations we conclude the behavior of the microbial loop and interactions generated between functional guilds is highly variable along individual transects and between the Shark River and Taylor River transect. Wet dry season dynamics partially explain temporal variability in microbial dynamics along the individual transects yet responses were unique for each section of the transect as freshwater versus estuarine versus Bay. Relationships between salinity and microbial parameters in this case, were not easily discerned but were more consistent within the two river transects than between river transects. As of 2020-06-05, PAM is no longer considered accurate and pigment data are no longer reported.

sample water collected 10 cm below the water surface. Method Step Description Microbial Analyses, Water samples were collected, processed, and analyzed to determine bacterial abundance, algal energetics and chl a by phytoplankton guild, enzyme activity, and heterotrophic bacterial production. Samples for microbial analyses were collected in washed, acid-rinsed, ADDIH2O rinsed, then sample rinsed brown, 250 ml, Nalgene bottles. Depth of sampling was 10 cm below the water surface. A sample for PAM analysis was set aside for a 10 hr dark acclimation period. Bacterial abundance was determined through epifluorenscence microscopy using DAPI DNA stain after preservation with 2 percent bacterial free phosphate buffered formalin and dark storage. Slides were made within 14 days of collection and counted immediately after they were prepared. Algal dynamics were determined through PAM (pulse-amplitude modulation) fluorescence within 24 hours of collection. (NOTE (2/22/2021): PhytoPAM measurements were not calibrated, per Henry Briceno). Algal energetics samples were analyzed using PAM fluormetry for chl a content and productivity irradiance curves. Heterotrophic bacterial production was determined using tritiated thymidine uptake within 24 hours of collection. We incubated each of the duplicate samplings per site with 3 replicates and one blank of 10 ml for each sample. The blank was killed with BFF to a final concentration of 4 percent. Stock tritiated thymidine was made with 2.58 mCi radioisotope with 30 ml of filter sterilized (0.2 um) water from Shark River. Each replicate and blank received 0.86 uCi ml-1 and was incubated at 22 degrees C for one hour. We also determined the specific activity for each incubation. We stopped the incubation period with TCA to final concentration of 5 percent then put the samples on ice for 15 to 45 minutes before filtering the sample onto nitrocellulose filters. A series of 3 rinses with 5 percent TCA and 80 percent ETOH of 1 ml each and filters were placed in scintillation vials. We added liquid scintillation cocktail and counted the samples after 24 hours with a Beckman liquid scintillation counter (Model 3801). Citation Bell, Russel T 1993.
