“…However, this value was largely affected by a single exceptionally high value (10.4) for the first 6 months of 2004 when measured CR was high, but zooplankton biomass was extremely low. Removing this outlier reduced the overall mean BR : ZR value to 2.7 (±1.2) (Table 4), well within the range of previous assumptions for this ratio in our earlier study (Berman et al , 2004).…”

“…Leucine uptake was converted to carbon uptake using the conversion factors of Simon & Azam (1989) with an isotope dilution factor of 2. These factors have been previously found to yield consistent results for BP in this lake (Pinhassi & Berman, 2003; Berman et al , 2004). BA was measured by 4′‐6‐diamidino‐2‐phenylindole (DAPI) staining and epifluorescence microscopy (Porter & Feig, 1980).…”

“…In a previous publication (Berman et al , 2004), we applied a somewhat similar approach to evaluate BR and BGE in Lake Kinneret from 2001 to 2003, but in that case, we assumed a priori values for the ratio BR : ZR and did not use measured ZR data.…”

Semi-annual averaged values of photosynthetic carbon fixation (PCF), community respiration (CR), bacterial productivity (BP) and zooplankton carbon biomass, measured biweekly or monthly, were used to obtain long-term estimates of bacterial respiration (BR) and bacterial growth efficiency (BGE) in Lake Kinneret from 2001 through 2007. We posited that CR=BR+phytoplankton respiration (PR)+zooplankton respiration (ZR). Based on the results of independent experimental series, PR was estimated as 0.3 x gross primary production (GPP) and GPP as 1.5 x PCF. ZR was determined by multiplying zooplankton carbon biomass, measured biweekly, with published respiration rates for major zooplankton groups. From these data, we calculated BR and consequently BGE, determined as BP/(BR+BP). Over the entire study period, BR averaged 49 (+/-10)% of CR and was consistently higher during the first half of the year. Semi-annual averaged BGE ranged from 26% to 53%, mean 39 (+/-9)%. Similar values of BGE were obtained if we did not use the measured values for ZR, but estimated BR+ZR from CR-PR and then assumed that BR ranged from two to three times ZR. The approach outlined in this paper can be useful for determining BGE in aquatic systems where long-term data sets of PCF, CR and BP are available.

“…In the Hudson River, for example, high inputs of allochthonous organic matter and the associated turbidity limited algal production (Findlay et al, 1991) while in the Neusiedler See, phytoplankton photosynthesis was largely controlled by turbidity and concomitant light attenuation (Dokulil, 1984). According to data from the Lake Taihu study, the underwater light penetration was poor which likely resulted in GPP not only lower than in other eutrophic lakes but also lower than in some mesotrophic aquatic ecosystems (e.g., Berman et al, 2004). Another factor which has been shown to depress algal biomass and production is heavy zooplankton grazing (Caraco et al, 1997;Jeppesen et al, 1990).…”

“…Some studies on NCP succession have monitored GPP and CR in time series >1 yr (Smith & Kemp 2001, Berman et al 2004, Duarte et al 2004. Time series of the metabolism in productive coastal communities have shown that GPP and CR may be in balance over annual time scales (Sherr & Sherr 1996, Serret et al 1999.…”

Gross primary production (GPP), community respiration (CR) and net community production (NCP) were studied for about 3 yr above ca. 30 m in summer. CR exhibited seasonal patterns coupled to the variation in GPP. NCP at the surface was generally positive and maximum throughout the observation period, whereas at the subsurface layer it was negative, suggesting a balanced relationship between production and consumption of oxygen in the euphotic zone. GPP, CR and NCP integrated within the euphotic zone ranged from 44 to 264 (mean ± SE: 111 ± 13), 10 to 311 (100 ± 15) and -94 to 112 (11 ± 8) mmol O 2 m, respectively. GPP and CR showed distinct seasonal patterns, and both tended to be higher from spring to summer (high productivity, HP) than from fall to winter (low productivity, LP). The threshold GPP for metabolic balance of the community (i.e. GPP:CR, P :R = 1) was higher during the HP period . These results suggest the importance of organic carbon produced in the past or elsewhere in sustaining a relatively high background CR rate during the HP period in Sagami Bay.
