Summary: Variable fluorescence techniques are increasingly used for assessing phytoplankton photosynthesis, but traditional amplitude-based models may lead to errors, especially under nutrient limitation. A new kinetic-based approach was developed to directly measure ETRs and estimate growth rates, showing improved accuracy compared to amplitude-based methods. Nutrient stress affects the quantum yield of photochemistry in Photosystem II, with a nonlinear relationship between F(v)/F(m) and growth rates. An algorithm was proposed to deduce electron yields of carbon fixation, enhancing fluorescence-based measurements of primary production and growth rates.

Summary: This study investigates the interactive effects of multiple stressors, including increasing temperatures, nutrient loading, and herbicides, on the growth of submerged macrophytes and other primary producers in shallow lakes. The results demonstrate that the joint impact of these stressors can alter the biomass of primary producers and their interactions, leading to a decline in macrophyte communities and a shift towards phytoplankton dominance.

Summary: Interactions between microalgae and bacteria play a direct role in global biogeochemical cycles, but many of these interactions are still unknown. In this study, the potential microalgal-bacterial associations in aquatic ecosystems were identified using 16S rRNA gene-based co-occurrence networks. The results showed that there were densely connected neighborhoods in microalgal-bacterial modules, with Proteobacteria and Bacteroidetes representing the main hubs. The study also found species-specificity as a global feature of microalgal associated microbiomes. The findings demonstrate the potential of using 16S rRNA gene-based co-occurrence networks to guide research on microalgal-bacterial associations.

Summary: The transition from winter to spring in the Antarctic marine ecosystem sees a shift from stored energy to photosynthesis, influenced by the timing of sea ice retreat. Different phytoplankton taxa respond uniquely to light conditions, affecting gene up-regulation and lipid production and utilization. Diatom and dinoflagellate taxa exhibit distinct transcriptional profiles and correlations to lipids, suggesting diverse ecological strategies during the polar winter-spring transition.

Summary: In the study, the long-term variability of phytoplankton phenology at a Long-Term Ecological Research site in the Gulf of Trieste, Slovenia was analyzed. It was found that the spring diatom peak was inconsistent and short-lived, while the autumn bloom was generally long and diverse. The average life span of phytoplankton assemblages in nearshore environments was found to be short-periodic (2-4 months), with more changes in typical assemblages observed in the second part of the year and the last part of the series.

Summary: Methane emissions from aquatic ecosystems, which contribute to about half of total global methane emissions, were traditionally attributed to methanogenic archaea in anoxic or suboxic conditions. However, recent studies have shown evidence of methane production in aerobic conditions in freshwater, brackish, and marine habitats. The role of submerged macrophytes in methane production in oxic waters has been largely overlooked, despite their presence in littoral zones of ponds, lakes, and coastal systems. Understanding the contribution of submerged macrophytes to methane emissions is crucial for estimating global methane emissions from aquatic ecosystems and improving our understanding of spatial and temporal dynamics of methane emissions.

Summary: This study combines a trait-based approach of mesozooplankton diversity with an ecological network analysis approach to investigate the ecological roles of mesozooplankton functional groups in three contrasting Arctic ecosystems. The results demonstrate that although the same main functional groups exist in all three ecosystems, the few significant changes in carbon circulation are strongly influenced by the initial whole-network properties and ecosystem productivity.

Summary: The potential ecological risks of nanoplastics (NPs) may be inaccurately assessed in some studies as they fail to consider the impact of environmental factors and their interactive effects. Here, the effects of six representative environmental factors on NPs' toxicity and mechanism to microalgae are investigated. The results show that microalgae become more resistant to NPs in N-rich or higher pH environments and the inhibitory effect of NPs on microalgae growth can even turn into a promotion effect.

Summary: In this study, concentrations of essential and toxic metals in Procambarus clarkii from Lake Trasimeno were quantified. The results showed differences in metal concentrations among tissues, seasons, and gender. Essential metals accumulated in higher concentrations and showed stronger associations, especially in females. Significant differences in concentrations were observed between seasons for essential metals and silver. A seasonal toxicity index indicated that nickel contamination levels in sediments were affected by fluctuating hydrological levels of the lake.

Summary: Coastal phytoplankton exhibit remarkable variability, and this study analyzed phytoplankton samples from the Gulf of Naples in the Mediterranean Sea to identify species associations and understand their composition, seasonal patterns, and environmental drivers. Cluster analysis revealed seven main groups of species, with five recurring in the same seasons and two displaying bimodal occurrence or no clear seasonality. Differences in occurrence were primarily associated with temperature and salinity. Diatoms were present in all associations, along with species from diverse phylogenetic groups. The stability of associations was related to phenological recurrence and overlap, while trait compositions indicated variable environmental filtering across seasons.

Summary: The presence and interactions of phytoplankton parasites, particularly Chytridiomycota, in the water column and sediments of the Gulf of Naples were investigated. Diatoms were found to dominate the upper layers of the water column, and Chytridiomycota were predominantly present in these layers, coinciding with diatom distribution. Laboratory incubations confirmed parasitic interactions between Chytridiomycota and diatoms. A 3-year metabarcoding time-series analysis revealed the recurrent presence of chytrids, but no clear patterns of co-occurrence with diatoms were observed. The chytrid community in sediments showed higher diversity compared to the water column samples. Overall, parasites were found to be a common component of the marine protist communities and understanding their interactions is crucial for understanding phytoplankton dynamics.

Summary: Ocean acidification caused by increased atmospheric CO2 concentrations is threatening calcifying organisms such as corals. This study examined the adaptation of Mediterranean coral Balanophyllia europaea to low pH/high pCO(2) conditions. It found that the coral's dinoflagellate endosymbiont density increased at lower pH sites, along with changes in the distribution of symbiont haplotypes. The results also suggested an increase in autotrophy and diazotroph N-2 fixation in the coral tissue under ocean acidification. Overall, this study highlights the ability of some corals to adapt to predicted future ocean acidification scenarios.

Summary: In this study, the presence of microplastics (MPs) was assessed in different compartments of two high-mountain lakes in Italy. MPs were found in sediment samples, tadpoles, and fish, but not in water and zooplankton samples. The abundance of MPs was higher in the lower lake compared to the upper lake. The use of a certain fish species was suggested as an indicator of MP pollution in high-mountain lakes.

Summary: This study compared two long-term phytoplankton time series in the Northern Adriatic Sea and found that the coastal station was more variable and influenced by the Western Adriatic Current and riverine inputs. The offshore phytoplankton community showed higher biodiversity due to its more oligotrophic condition. Graph-network analysis was a useful tool to study the phytoplankton community. Evaluating the Good Environmental Status should consider oceanographic differences and use multiple statistical approaches.

Summary: Long-term ecological research in the Gulf of Naples has shown changes in the pelagic system since 1984. Zooplankton composition and abundance have undergone significant shifts in response to climate variation and local atmospheric forcing. Some neritic copepods have disappeared or decreased while offshore species have increased, indicating changes in the influence of open waters. Despite these changes, overall zooplankton abundance and composition have not significantly changed, suggesting restructuring within the community.
