    Notes: Abstract: The feeding of the marine ciliate Euplotes mutabilis was studied using bacteria (Vibrio natriegens) doubly labelled with 3H-thymidine and 14C-leucine. In the presence of abundant bacteria (30 × 106 bacteria ml−1), an average Euplotes cell (initially without food vacuoles) with a protein content of 12 ng consumed 16 × 103 bacteria in the first hour and 27 × 103 bacteria over four hours, accumulating about 60% of the bacterial protein into ciliate macromolecules. Euplotes which had been starved or under-fed to reduce cell protein biomass to 7 or 9 ng consumed significantly fewer bacteria, but the gross growth efficiency for protein did not change. The rate of consumption of bacteria by large Euplotes of protein content 15 ng was initially less than that of 12 ng cells, and it decreased markedly before the end of a 4-hour experiment. Recently divided cells ingested bacteria rapidly, but showed a reduced gross growth efficiency of about 40%. At low bacterial concentrations (6 × 106 bacteria ml−1) the rates of ingestion were markedly reduced to between 〈inlineGraphic alt="inline image" href="urn:x-wiley:01686496:FEM137:FEM_137_mu1" location="equation/FEM_137_mu1.gif"/〉 and 〈inlineGraphic alt="inline image" href="urn:x-wiley:01686496:FEM137:FEM_137_mu2" location="equation/FEM_137_mu2.gif"/〉 of maximal levels; the smallest cells could not sustain feeding activity at the low prey concentration and gross growth efficiency fell from 43 to 20% during a 4-hour experiment. The strategy adopted by Euplotes in response to local fluctuations in food supply involves rapid consumption with high growth efficiency in times of plenty, but slow shrinkage without cell division to survive in times of shortage.

    Notes: . Bacteria were deposited in tubes as compact pellets by centrifuging suspensions of cultured Vibrio at stationary phase. Numbers and protein biomass of flagellates added to these tubes and of the Vibrio, were followed and compared with the growth of the same and other protists on identical, uncentrifuged Vibrio. The flagellates Bodo saliens and Caecitellus parvulus, which could not be seen to multiply in tubes of suspended bacteria, grazed deposited bacteria actively as did the more versatile flagellate Cafeteria roenbergensis. The growth of these flagellates and their consumption of deposited bacteria were very similar to those of the flagellate Pteridomonas danica or the ciliate Uronema marinum fed with suspended bacteria, although deposit-feeders grew more slowly. Gross growth efficiencies (30–60%) of deposit-feeding flagellates were similar to those of the suspension-feeding protists. Caecitellus consumed 55 Vibrio to produce one flagellate, while 4,500 Vibrio were consumed to produce one Uronema. Surface-feeding flagellates are shown to be efficient bacterivores, capable of restricting the numbers of bacteria deposited on surfaces just as other protozoa control numbers of suspended bacteria.

    Notes: Bacterivorous protozoa secrete glucosaminidase enzymes which digest peptidoglycans in bacterial cell walls. Phagotrophic protozoa store digestive enzymes in lysosomes before release into food vacuoles where digestion takes place initially at acidic pH. The quantity of glucosaminidase can be assayed by measuring the rate of formation of the fluorescent product 4-methylumbelliferone by cleavage of 4-methylumbelliferyl-n-acetyl-β-d-glucosaminide. Flagellate and ciliate cells lysed with detergent possessed glucosaminidase activity which remained steady over at least 24 h. The enzyme activity increased in direct proportion to the biomass for each species tested, although the level of activity varied in different species in a way that probably relates to the ecological strategy of the species. Heterotrophic nanoplankton sampled at eight stations in waters of widely different trophic status along an Atlantic Meridional Transect showed a very strong correlation between glucosaminidase activity and estimated biomass. We conclude that this calibrated glucosaminidase assay can provide a quick and effective method of estimating the biomass of heterotrophic nanoplankton.

    Notes: Protozoa are the main consumers of heterotrophic bacteria in aquatic habitats. The numbers of these bacteria and protozoa in oligotrophic areas of the open ocean are low, and current methods lack the sensitivity to assess rates of bacterivory in such waters. A new method is proposed for estimating bacterivory on dual radioactively labelled natural bacteria using living ambient prey bacteria and separation of predators from prey by fractionation. This approach is sufficiently sensitive to measure the consumption of less than 1% of the labelled bacteria during a 13-h incubation period. When tested on samples collected from 27 stations in mesotrophic and oligotrophic regions of the North and South Atlantic Oceans, about 17% of metabolically active bacteria were grazed per day and about 60% of consumed prey biomass labelled with 14C-leucine was retained by the predators.

    Depth related amino acid uptake by Prochlorococcus cyanobacteria in the Southern Atlantic tropical gyre (2004)

    Notes: Ambient concentrations and turnover rates of two amino acids, leucine and methionine, by total bacterioplankton and Prochlorococcus cyanobacteria were determined along a latitudinal transect across the Southern Atlantic gyre using a combined isotopic dilution and flow cytometric sorting technique. The ambient concentrations of methionine (0.2–0.65 nM) were about 2 times higher than the concentrations of leucine, while the turnover rates of the two amino acids were remarkably similar (0.1–0.7 nM d−1). The concentrations of both amino acids did not vary significantly with depth between 3 and 150 m but their turnover rates were 1.5–2 times higher in the top 3–80 m. Prochlorococcus took up amino acids in situ at high rates. Using a representative 35S-methionine precursor, about 25% of total bacterioplankton consumption of amino acids could be assigned to Prochlorococcus with low red fluorescence (Pro LRF) inhabiting the surface mixed layer down to 80 m and about 50% assigned to Prochlorococcus with high red fluorescence (Pro HRF) living below 100 m. In the same deep waters the cellular amino acid uptake of Pro LRF was less than 6% of that of the Pro HRF, indicating declining metabolic activity of the former. The mean cellular uptake rate of Pro HRF at depths below 120 m was 2.5 amol cell−1 d−1, 4 times higher than the rates of Pro LRF in the top 80 m. The difference could be partially explained by Pro HRF cellular biomass being twice that of Pro LRF. The biomass specific rates of Prochlorococcus were comparable or higher (particular of the Pro HRF) than that of other bacterioplankton. The reported findings could explain ecological success of mixotrophic Prochlorococcus cyanobacteria over both strictly autotrophic algae and heterotrophic bacteria in oligotrophic regions sustained by nutrient remineralisation.

    Notes: A flow cytometric sorting technique for direct determination of bacterial biomass assimilation by phagotrophic flagellates was developed and tested in laboratory culture experiments. Living Vibrio bacteria were quantitatively pulse-chase labelled with [35S]methionine tracer and fed to Pteridomonas flagellates. Flow sorting revealed that the isotopically labelled material is in either bacterial prey or flagellate predators and the egested bacterial debris contained negligible amounts of tracer. These experimental results confirm an earlier hypothesis that flagellates release metabolised bacterial proteins primarily in a dissolved form. The assimilation efficiency of the Vibrio protein biomass by Pteridomonas was low, only about 20%, independently of the amount of consumed bacterial biomass, confirming our earlier indirect estimates. Additionally, against expectations that cells decrease their metabolic activity whilst preparing for and engaged in division, we found that the precursor uptake rates by flow sorted bacterial cells at the S + G2 cell cycle stages were constantly 1.5 times higher than those of cells at the G1 stage.

    Notes: Abstract: The rates of ingestion of bacteria and of accumulation of bacterial biomass by hungry Pteridomonas danica and Paraphysomonas imperforata were measured using dual radioactive-labelled bacteria in experiments lasting 4–8 h. Pteridomonas continuously consumed 4–5 bacteria h−1 throughout experiments lasting 8 h, irrespective of bacterial concentration above a threshold of about 5 × 105 bacteria ml−1, and continued to catch bacteria even below this density. The clearance rate of about 1 nl cell−1 h−1 at higher bacterial concentrations increased three or four times as bacterial numbers fell. Paraphysomonas cells, with only half the biomass of Pteridomonas, ingested up to 10 bacteria h−1 at high bacterial concentrations, and gradually reduced the feeding rate, effectively ceasing to feed at 106 bacteria ml−1; their initial clearance rate of 1–2.5 nl cell−1 h−1 subsequently fell as low as 0.1 nl cell−1 h−1. Estimation of feeding rate by extrapolation from short-term experiments on such flagellates requires extreme caution. These flagellates, starved to levels typical of the natural environment, accumulated ingested bacterial biomass at an efficiency of between 16 and 21%, indicating that in nature they would recycle 80% or more of the nutrients contained in their food.

    Description: Members of the prokaryotic picoplankton are the main drivers of the biogeochemical cycles over large areas of the world's oceans. In order to ascertain changes in picoplankton composition in the euphotic and twilight zones at an ocean basin scale we determined the distribution of 11 marine bacterial and archaeal phyla in three different water layers along a transect across the Atlantic Ocean from South Africa (32.9°S) to the UK (46.4°N) during boreal spring. Depth profiles down to 500 m at 65 stations were analysed by catalysed reporter deposition fluorescence in situ hybridization (CARD-FISH) and automated epifluorescence microscopy. There was no obvious overall difference in microbial community composition between the surface water layer and the deep chlorophyll maximum (DCM) layer. There were, however, significant differences between the two photic water layers and the mesopelagic zone. SAR11 (35 ± 9%) and Prochlorococcus (12 ± 8%) together dominated the surface waters, whereas SAR11 and Crenarchaeota of the marine group I formed equal proportions of the picoplankton community below the DCM (both ~15%). However, due to their small cell sizes Crenarchaeota contributed distinctly less to total microbial biomass than SAR11 in this mesopelagic water layer. Bacteria from the uncultured Chloroflexi-related clade SAR202 occurred preferentially below the DCM (4-6%). Distinct latitudinal distribution patterns were found both in the photic zone and in the mesopelagic waters: in the photic zone, SAR11 was more abundant in the Northern Atlantic Ocean (up to 45%) than in the Southern Atlantic gyre (~25%), the biomass of Prochlorococcus peaked in the tropical Atlantic Ocean, and Bacteroidetes and Gammaproteobacteria bloomed in the nutrient-rich northern temperate waters and in the Benguela upwelling. In mesopelagic waters, higher proportions of SAR202 were present in both central gyre regions, whereas Crenarchaeota were clearly more abundant in the upwelling regions and in higher latitudes. Other phylogenetic groups such as the Planctomycetes, marine group II Euryarchaeota and the uncultured clades SAR406, SAR324 and SAR86 rarely exceeded more than 5% of relative abundance.

    Effects of acute ocean acidification on spatially-diverse polar pelagic foodwebs:Insights from on-deck microcosms (2016)

    Description: The polar oceans are experiencing some of the largest levels of ocean acidification (OA) resulting from the uptake of anthropogenic carbon dioxide (CO2). Our understanding of the impacts this is having on polar marine communities is mainly derived from studies of single species in laboratory conditions, while the consequences for food web interactions remain largely unknown. This study carried out experimental manipulations of natural pelagic communities at different high latitude sites in both the northern (Nordic Seas) and southern hemispheres (Scotia and Weddell Seas). The aim of this study was to identify more generic responses and greater experimental reproducibility through implementing a series of short term (4 day), multilevel (3 treatment) carbonate chemistry manipulation experiments on unfiltered natural surface ocean communities, including grazing copepods. The experiments were successfully executed at six different sites, covering a diverse range of environmental conditions and differing plankton community compositions. The study identified the interaction between copepods and dinoflagellate cell abundance to be significantly altered by elevated levels of dissolved CO2 (pCO2), with dinoflagellates decreasing relative to ambient conditions across all six experiments. A similar pattern was not observed in any other major phytoplankton group. The patterns indicate that copepods show a stronger preference for dinoflagellates when in elevated pCO2 conditions, demonstrating that changes in food quality and altered grazing selectivity may be a major consequence of ocean acidification. The study also found that transparent exopolymeric particles (TEP) generally increased when pCO2 levels were elevated, but the response was dependent on the exact set of environmental conditions. Bacteria and nannoplankton showed a neutral response to elevated pCO2 and there was no significant relationship between changes in bacterial or nannoplankton abundance and that of TEP concentrations. Overall, the study illustrated that, although some similar responses exist, these contrasting high latitude surface ocean communities are likely to show different responses to the onset of elevated pCO2.

    Phytoplankton responses and associated carbon cycling during shipboard carbonate chemistry manipulation experiments conducted around Northwest European shelf seas (2014)

    Publication Date: 2024-03-15
    Description: The ongoing oceanic uptake of anthropogenic carbon dioxide (CO2) is significantly altering the carbonate chemistry of seawater, a phenomenon referred to as ocean acidification. Experimental manipulations have been increasingly used to gauge how continued ocean acidification will potentially impact marine ecosystems and their associated biogeochemical cycles in the future; however, results amongst studies, particularly when performed on natural communities, are highly variable, which may reflect community/environment-specific responses or inconsistencies in experimental approach. To investigate the potential for identification of more generic responses and greater experimentally reproducibility, we devised and implemented a series (n = 8) of short-term (2-4 days) multi-level (〉=4 conditions) carbonate chemistry/nutrient manipulation experiments on a range of natural microbial communities sampled in Northwest European shelf seas. Carbonate chemistry manipulations and resulting biological responses were found to be highly reproducible within individual experiments and to a lesser extent between geographically separated experiments. Statistically robust reproducible physiological responses of phytoplankton to increasing pCO2, characterised by a suppression of net growth for small-sized cells (〈10 µm), were observed in the majority of the experiments, irrespective of natural or manipulated nutrient status. Remaining between-experiment variability was potentially linked to initial community structure and/or other site-specific environmental factors. Analysis of carbon cycling within the experiments revealed the expected increased sensitivity of carbonate chemistry to biological processes at higher pCO2 and hence lower buffer capacity. The results thus emphasise how biogeochemical feedbacks may be altered in the future ocean.
