At St. S1, 27 species of pelagic polychaetes belonging to 13 genera and six families were identified. The annual mean abundance was 35.0 ind. 1000 m-3 and the biomass was 17.3 mg WW 1000 m-3. At St. S1, the numbers of genera and species were higher and the annual mean abundance and biomasses were much lower than St. K2. The pelagic polychaetes often peaked in the mesopelagic layer at St. K2, with the carnivores and particle feeders peaking in the epipelagic and mesopelagic layers, respectively. At St.S1, the carnivorous species predominated throughout the entire water column, and were most abundant in the epipelagic layer. Thus, In the western Pacific Ocean, the subarctic pelagic polychaete community structure changed vertically with feeding ecology.

Cell growth was highest under conditions of 25–28°C, salinity 10–20 and high light, which represented the preferred physical niche for bloom formation in the present day. In the Chesapeake Bay, blooms generally occur at 25–29°C and salinity 10–14, while low-biomass occurrences have been found at salinities 15–29, consistent with the laboratory findings. High light increased the thermal sensitivity of K. veneficum and lowered the thermal optima for growth. Under conditions of low light, and salinity 10–20, cells exhibited the highest thermal optima for growth. The highest upper thermal maxima were observed at salinity 30, suggesting that cells in the lower estuary would be more thermally resistant than those in upper and mid-estuarine regions, and therefore these higher salinity regions may provide over-summering habitats for K. veneficum. Cellular C and N were highly varied at the preferred salinity and temperature niche and C:N ratios showed decreasing trends with temperature.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43448928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas vesicles (GVs) are an important trigger for the occurrence of Microcystis blooms. To understand the effects of light and nutrients on GV content, the phytoplankton in Lake Erhai were investigated. The results showed that the average GV content in the surface water was higher than that in the deep water. The total nitrogen in water affected the GV content by limiting the protein content, and the content of GVs increased by 9.2 μm3/cell for each 1.0 pg/cell increase in the intracellular nitrogen content. Moreover, light and total phosphorus affected the GV content in deep water by limiting the energy supply, and the content of GVs increased by 52.4 μm3/cell for each 1.0 pg/cell increase in the intracellular phosphorus content. These results indicate that for lakes with low transparency, decreasing the total phosphorus concentration can reduce the GV content. Reducing the total nitrogen concentration can reduce the GV content and decrease the dominance of Microcystis in all lakes.

In Southeast Asia, green Noctiluca has a northern boundary of distribution in the Luzon Strait and the Vietnamese coast, approximately corresponding to the 25°C isotherm. We examined whether this boundary arose from the growth dependence of Noctiluca on temperature and/or that of P. noctilucae. We analyzed the effect of temperature on growth by examining one and four unialgal cultures of red and green Noctiluca, respectively, and two monocultures of the endosymbiont. Growth dependence on temperature was markedly different between host cells of green Noctiluca and monocultures of the endosymbiont, although some variations in growing temperature were observed among strains of both Noctiluca and the endosymbiont. Green Noctiluca grew at a temperature range of 20–31°C, whereas P. noctilucae did not grow at low temperatures ≤25°C. Growth rates of green Noctiluca were considerably higher when fed compared to monocultures. Our findings demonstrate that the effect of temperature on P. noctilucae growth is a crucial factor controlling the geographical distribution of green Noctiluca in the South China Sea. An implication of this finding is discussed in the context of global warming.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41429390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, increased biomass, nutrient concentrations and oxygen demand do not lead to undesirable environmental effects if the flow of carbon/energy from primary producers toward high trophic levels is consistently preserved. Consequently, traditional indicators might provide a misleading assessment of the eutrophication risk. To avoid this, we propose to evaluate eutrophication by using a new index based on plankton trophic fluxes instead of biogeochemical concentrations. A preliminary, model-based, assessment suggests that this approach might give a substantially different picture of the eutrophication status of our seas, with potential consequences on marine ecosystem management. Given the difficulties to measure trophic fluxes in the field, the use of numerical simulations is recommended although the uncertainty associated with biogeochemical models inevitably affects the reliability of the index. However, given the effort currently in place to develop refined numerical tools describing the marine environment (Ocean Digital Twins), a reliable, model-based, eutrophication index could be operational in the near future.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":"45 3","pages":"413-420"},"PeriodicalIF":2.1,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10243849/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9598748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mean population size not only depends on the size of individuals, but also on the size distribution of individuals within the population. Mean community size is additionally influenced by the composition of species (larger- or smaller-sized species). Shallow lakes within semi-arid landscapes are prone to experience large changes in temperature and salinity, which affect the zooplankton size structure. Higher temperatures are expected to result in smaller average body size, while the effect of salinity appears to depend on the range under study. Here we analyze zooplankton body size patterns across shallow lakes from the semi-arid central region of Argentina. All community size descriptors point to decreasing size and a narrow size range at higher temperatures. On the other hand, the maximum average community body size occurred at intermediate (~30 gL−1) salinity levels. The combined effect of both variables resulted in a bell-shaped pattern, with maximum community body size toward lower temperatures and intermediate salinities. Based on future temperature scenarios, one may anticipate an overall decrease in community body size. But such prediction is strongly conditioned by regional and local trends in salinity.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136338633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
