A prevailing ecological framework suggests that ciliates dominate under cool, mixed conditions typical of late winter and early spring, whereas dinoflagellates prevail in warmer, stratified waters during late spring and summer. This review highlights how temperature, stratification, nutrient dynamics, prey composition, turbulence and top-down control shape seasonal and regional patterns. While the ciliate-dinoflagellate succession is often observed in temperate seas, it is not universal. Polar regions exhibit compressed seasonality, while tropical systems show weak seasonality, often dominated by mixotrophic dinoflagellates. The widespread occurrence of mixotrophy in both groups complicates this duality, allowing species to persist across contrasting environmental conditions. Ultimately, the relative dominance of ciliates or dinoflagellates reflects a context-dependent interplay of multiple drivers rather than a fixed seasonal rule. As climate change intensifies ocean stratification and alters nutrient regimes, understanding these dynamics becomes critical to predict shifts in plankton communities and their consequences for marine biogeochemical processes and ecosystem functioning.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":"47 5","pages":"fbaf049"},"PeriodicalIF":2.0,"publicationDate":"2025-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12450349/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145124877","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}

We used correlation matrices of taxon relative abundances to calculate network metrics across land-use types and time periods. We found that lake communities currently experiencing high human impact changed through time, showing a decrease in connectance (proportion of realized to potential links) and an increase in modularity (measure of network subcommunities); these patterns were also observed in our full core analyses as well as in our randomized simulation exercise.

Most research to date on the drivers of cyanoHABs focuses on environmental factors in the typical \"growing season\" despite evidence that cyanobacteria overwintering dynamics may have substantial effects on cyanobacteria seasonal succession and bloom formation. Additionally, the growing season is now beginning earlier and ending later in many parts of the world. Here, we examine the impacts of light, temperature and nutrients on the magnitude and timing of cyanobacteria recruitment from sediments in two hypereutrophic reservoirs in the Midwestern USA in the early spring season via microcosm recruitment experiments. We observed that recruitment was greatest at the first sampling point (Day 3), then declined throughout the rest of the 18-day experiment for both reservoirs. Further, increasing light and temperature significantly promoted recruitment in both systems, while nutrient additions were only a significant driver of recruitment in one lake. The recruited cyanobacteria community identity was similar in both lakes, with Planktothrix, Raphidiopsis and Pseudanabaena being most abundant. This study highlights the complex, interactive effects of environmental variables on cyanobacteria recruitment.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":"47 5","pages":"fbaf045"},"PeriodicalIF":2.0,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12418944/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145040059","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}

Concomitantly phytoplankton biomass increased and shifted from dominance of diatoms to Cyanobacteria, which were hypothesized to be of less nutritional quality, causing the shift in zooplankton. We investigated whether the natural assemblage of Cyanobacteria in Mwanza Gulf negatively affected growth and fecundity of cladocerans. In 2010-2011, we performed life-history experiments with the cladoceran Daphnia lumholtzi, feeding it natural seston from Mwanza Gulf from three different locations. A laboratory-strain of the green alga Scenedesmus obliquus, proven to be high-quality food, was used as a control. Growth of D. lumholtzi in the rainy season and at one station in the dry season was just as high as in the control treatment. If there were negative effects of natural seston these were small.

We conducted a meta-analysis of stage-specific vertical distribution and its relationships with environmental variables (temperature, salinity, irradiance, chlorophyll-a) in the epipelagic layer (0-200 m) of the North Atlantic during spring and summer (21 March to 21 September). Fitting a GAM model, we analyzed data from 47 years (1971-2018) with the aim to discern common, stage-specific responses to environment across the area. Highest abundances were observed in the upper 50 m in spring (at 5°C) and summer (at 7.5°C). The timing of the phytoplankton bloom emerged as a key driver determining vertical distribution, with all stages found shallower during the seasonal surface Chl.-a maximum. Contrary to reports of mismatch with global warming, the data indicated a region-wide match of spring bloom and Calanus. In the coldest areas of its habitat (< 1°C), the copepods stayed closer to surface, potentially to fulfill development, while in warmest areas (>10°C), early stages stayed deeper likely to avoid warm surface waters.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":"47 4","pages":"fbaf019"},"PeriodicalIF":2.0,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12205936/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528463","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}

Here, we use a multi-trait analysis to quantify how thermal regime (constant vs. fluctuation by ±3°C around mean temperature) alters the effect of temperature (18 vs. 22°C) on the growth, elemental composition, photosynthetic performance and metabolism of five phytoplankton species (Emiliania huxleyi, Micromonas commoda, Skeletonema costatum, Synechococcus sp. and Thalassiossira rotula) during exponential growth and stationary phases. Our results showed a high degree of inter-trait and inter-specific variability in the response to the temperature treatments. The carbon-based growth rates tended to be reduced by thermal fluctuations (by 20-29%), particularly under warming conditions. By contrast, thermal fluctuations increased the photosynthesis rates up to 25%, regardless of the growth phase. The carbon-to-nitrogen and carbon-to-chlorophyll a ratios, maximum photochemical yield of photosystem II and relative maximum electron transport rates did not show a clear response to interactions between thermal fluctuations and temperature.

This study used a multivariate approach to determine interspecific trait variability and plasticity of 10 Baltic Sea phytoplankton species along the salinity gradient. Phytoplankton species representing a broad range of sizes and taxonomic groups were grown at six salinity conditions (0, 5, 15, 20, 30 and 35 psu), and 15 different traits were measured at the end of the experiment. Results showed species-specific salinity preferences. Nutrient uptake and resource use efficiency (RUE) explained interspecific trait variability among the species. Variability in nutrient uptake reflected species-specific differences in cell size. RUE and cellular elemental content were the most plastic traits across the salinity gradient and did not scale with cell size. Interestingly, low trait plasticity did not always translate into low biomass production, as a diatom Phaeodactylum tricornutum exemplified. As expected, the salinity range between 5 and 20 psu was optimal for most phytoplankton species, corresponding to the brackish Baltic Sea where they were isolated. Many species survive in salinities above this range, but not in freshwater, which can have consequences for the plankton community functioning with predicted Baltic Sea freshening.","PeriodicalId":16800,"journal":{"name":"Journal of Plankton Research","volume":"47 3","pages":"fbaf015"},"PeriodicalIF":1.9,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12021263/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144004858","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}
