Summary: High throughput sequencing is being used to improve the efficiency of monitoring diatoms in aquatic ecosystems. This study demonstrated the potential of a standard V4 515F-806RB primer pair in recovering diatom plastid 16S rRNA sequences, and successfully identified diatom operational taxonomic units from freshwater biofilm samples in Australia. The results indicate that existing 16S rRNA amplicon datasets can be used to map diatom distribution, inform phylogeny and ecological health assessments, and have potential applications in ecological and industrial fields.

Summary: This study investigates the differences in responses between cyanobacteria and green algae, which are the recommended test organisms for toxicity assessments, to the same chemical. The results show that these two species have different resistance mechanisms and can alleviate the toxicity of sulfamethoxazole through different pathways. Inconsistent assessment results for antibiotics using cyanobacteria and green algae are likely due to their different resistance mechanisms. Improved indicators or comprehensive assessment methods should be considered for environmental toxicity assessments.

Summary: Microbes play a vital role in element cycling and ecosystem functioning, yet there are still many unanswered questions about their role in ecology. This study analyzes the relationship between lake microbiomes and the land cover surrounding the lakes using machine learning methods. The results show that the microbial community of the lakes is significantly correlated with herbaceous and open spaces, but the correlation with land cover categories is generally lower than with physico-chemical parameters. The integration of land cover and physico-chemical bioindicators provides insights into the environmental drivers of the lake microbial community composition and allows for the study of the ecosystem's structure from the standpoint of the microbiome.

Summary: Snow algae in Antarctica are important terrestrial photosynthetic organisms that mostly grow in low lying coastal snow fields. The study successfully used high-resolution satellite imagery to track the growth of red and green blooms throughout the summer, revealing that green algae dry biomass was over three times that of red algae and the calculated snow algal area was 17.5 times greater than estimated with coarse resolution imagery, suggesting a greater contribution to net primary productivity on Antarctica.

Summary: The potential of converting solar energy into electrical current through photosynthetic organisms can produce clean energy. Researchers are exploring the use of photosynthesis to create bio-photoelectrochemical cells (BPECs) that transform light energy into electricity. Different materials like plants, seaweeds, unicellular photosynthetic microorganisms, and thylakoid membranes have been studied to construct efficient and non-polluting BPECs for green energy production. However, there are challenges such as the need for specific conditions, sensitivity to photoinhibition and other stresses, and electron extraction.

Summary: Good ecological status varies depending on national criteria, typology approach, and classification systems used. Establishing nutrient criteria that consistently support good ecological status is important for river management. The study analyzes different ecological statuses based on typology, classification systems, and biological elements, and discusses the implications for river management. The results suggest that current nutrient criteria should be revised to provide a more ecologically coherent approach to preserving or restoring good ecological status.

Summary: Butterflies are important indicators of biodiversity and ecosystem functions, and their abundance and occurrence are strongly influenced by environmental factors such as temperature and precipitation. Species richness is higher in cooler and hilly/mountainous regions compared to coastal plains and semi-arid areas, with temperature being a more significant driver than precipitation. Overall, butterfly faunas show a strong response to temperature changes, which may lead to species disappearance and rarity in marginal sites due to global warming.

Summary: Microbes that recycle nutrients and detoxify ecosystems have the potential to meet future energy needs by producing biohydrogen through the collaboration of autotrophic and heterotrophic microbes. The production of hydrogen in granules involves mutual exchange of nutrients and electrons among microbes. The development of granular algae-bacteria consortia, optimization of hydrogen yield in coculture, investigation of key enzymes, and potential engineering strategies for enhanced hydrogen production are all important aspects discussed in this review.

Summary: This paper provides a comprehensive overview of the threats, risks, and integrated water management elements in freshwater ecosystems. It discusses the impacts of human activities and conservation issues related to freshwater systems. The complex matrix of stressors, including pollution, habitat fragmentation, and unsustainable exploitation, significantly affects the qualitative and quantitative changes in freshwater ecosystems and their ability to sustainably provide products and services to human societies. Only internationally integrated policies, strategies, assessment, monitoring, management, protection, and conservation initiatives can prevent the long-term deterioration of Earth's freshwater resources.

Summary: A total of 385 species of diatoms were identified in the phytoplankton of 14 small Arctic tundra water bodies in the vicinity of Tiksi Bay, with each lake having a unique species composition. The ecological preferences of diatom species in the studied water bodies were determined for more than 90% of the list. Indicator characteristics showed a certain response of the species composition of phytoplankton to changes in salinity and organic pollution.

Summary: Forty years ago, the estuary of the Black Sea was transformed into a freshwater reservoir through the Danube-Sasyk Canal. The inflow of the Danube water into the Sasyk plays a crucial role in the water balance and affects the aquatic environment. The changes in algal communities during the transformation stages were studied, and the influence of salinity on their composition was observed. The species list of algae and cyanobacteria in the Sasyk was presented for the first time, and the importance of the Danube River in maintaining the ecological status of the reservoir was emphasized.

Summary: Through morphological, ecological, and distributional analysis, it was discovered that Chara denudata from South Africa and C. dissoluta from Central Europe, originally believed to be the same species, are in fact distinct species. The presence of different traits and their distinct biology, habitat preference, and distribution confirms that the 'unfinished' morphogenesis in charophytes can hide different speciation pathways.

Summary: This study tested the hypothesis of year-round presence of toxigenic Microcystis and cyanotoxins in Lake Ytyk-Kyuyol. Three independent approaches were used: mass-spectrometry, molecular methods, and light microscopy. Microcystis flos-aquae and M. aeruginosa were the dominant species, and the presence of M. aeruginosa and microcystin biosynthesis genes were confirmed. Microcystin concentration was low, indicating the potential viability of overwintering colonies.

Summary: In the modern context of climate change and human impact on aquatic ecosystems, studying the diversity of organisms in the Arctic is crucial. This study focuses on the biodiversity of Arctic rivers and identifies the environmental factors influencing phytoplankton diversity through innovative methods such as ecological mapping and bioindication. The research reveals an increase in the diversity of phytoplankton towards the mouth of the Anabar Arctic River, indicating a link to industrial discharges and increased turbidity. Although weak effects of organic pollution and toxicities from settlements were identified, the study also highlights natural self-purification processes taking place in the studied Arctic River.

Summary: The benthic diatom assemblages of Avusor Great Lake and Kocduzu Great Lake were investigated, revealing differences in species composition and abundance between the two lakes. Bioindication analysis showed that Kocduzu Great Lake has more alkaline water with less organic substances compared to Avusor Great Lake. Altitude was found to be the main factor influencing the diatom flora formation.
