Summary: Climate change is causing rapid and intense changes in aquatic communities and habitats. Previous research has focused on direct effects, while indirect and interactive effects have been overlooked. This overview of a special issue in Limnology and Oceanography addresses this knowledge gap, covering diverse habitats and emphasizing the importance of maintaining time-series data to identify indirect effects. Species-specific characteristics and habitat changes are also highlighted as key factors in understanding aquatic ecosystem responses. The results provide valuable insights for tackling the combined impacts of climate change and human activities on biodiversity and ecosystem functioning.

Summary: Through experimental research on submerged macrophytes, it was found that the impact of macrophytes on aquatic ecosystems varies over time, including effects on dissolved organic matter concentration and phytoplankton biomass. Macrophytes increased the variance of ecosystem metabolic rates and dissolved organic carbon composition, while also affecting the variability of phytoplankton biomass.

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: Investigations on the influence of green microalgae associated with cyanobacteria exposure to macrophytes and the production of cyanotoxins have not been previously explored. The effects of the presence of live plants and extracts of the Egeria densa, on the growth and saxitoxin production of Raphidiopsis raciborskii were investigated in the presence and absence of Chlorella vulgaris. The physical presence of the macrophyte reduced the biovolume of the cyanobacterium and its production of saxitoxins, while cultures exposed to aqueous extract had elevated saxitoxin levels. The green microalgae also increased the amount of cyanotoxins, especially when the macrophyte biomass was low. These findings suggest that E. densa can inhibit the growth of R. raciborskii and the production of cyanotoxins and that the presence of C. vulgaris can alter these processes.

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: As a widespread emerging pollutant, microplastics can interact with algal and bacterial communities in aquatic ecosystems. However, knowledge about the effects of microplastics on algae and bacteria in natural habitats is limited. Therefore, a mesocosm experiment was conducted to investigate the impact of nanoplastics on algal and bacterial communities in aquatic ecosystems dominated by different submerged macrophytes.

Summary: Cyanobacteria can form harmful algal blooms in eutrophic freshwater ecosystems, posing a threat to wildlife, public health, and recreational waters. Molecular methods are increasingly recommended for the detection and quantification of cyanobacteria and cyanotoxins. However, each molecular detection method has its own advantages and limitations for monitoring algal blooms. Integration of modern technologies such as satellite imaging, biosensors, and machine learning/artificial intelligence can help overcome these limitations.

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: 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: This study analyzed the coverage of DNA barcode reference libraries for phytoplankton species in the southeastern Mediterranean region of Italy and evaluated the potential of DNA metabarcoding and eDNA in this area. The results showed a significant lack of barcodes, particularly for the COI marker gene. The interspecific genetic distance analysis demonstrated that the 18S marker gene could distinguish most species.

Summary: This study investigated the correlation between bacterioplankton composition and phytoplankton dynamics in a shallow lake known for recurrent cyanobacterial blooms. Changes in bacterial community occurred before the development of the phytoplankton bloom, suggesting that the environmental changes were first sensed by the bacterial community. The study also highlighted the relevance of spatial organization within different microenvironments in shaping these communities.

Summary: Compared with northern countries, there is limited data available on cyanobacterial blooms and their potential toxicity in lakes and ponds in sub-Saharan countries. To address this knowledge gap, a 17-month monitoring of a freshwater ecosystem, Lagoon Aghien in Ivory Coast, was conducted. The study found high richness and diversity of cyanobacterial community, with microcystins being the only detected cyanotoxin.
