Summary: Invasive alien species pose a significant threat to freshwater ecosystems globally. This study in Norway identified factors such as human behavior, infrastructure development, and lake connectivity as the most influential in determining the likelihood of establishment and future establishment risk of invasive fish species. By synthesizing risk assessments based on open data sources, tools for forecasting invasion hotspots can be constructed to facilitate mitigation actions and management strategies.

Summary: Freshwater ecosystems are facing increasing anthropogenic and climatic pressures, with eutrophication as a major threat leading to harmful algal blooms. Current interventions to prevent algal blooms are expensive, ephemeral, and disruptive, prompting interest in biological control methods. This study assesses the potential of using invasive aquatic plants to repress nuisance algae species through allelopathy.

Summary: This study investigated the effects of elevated CO2 on five freshwater phytoplankton species, showing varied responses in growth rates among species. The study suggests that as atmospheric CO2 levels rise, some species may become less of a problem to water quality, while others may become more dominant.

Summary: Invasive alien species have significant impacts on the trophic organisation and food web structure in ecosystems. Using the Ecopath with Ecosim modelling platform, this study examined the effects of three invasive fish species on a tropical freshwater pond ecosystem in India. The study found that these invasive species competed with native fish species and had negative impacts on other functional groups in the ecosystem.

Summary: Research has shown that metallic nanoparticles exhibit toxicity to algae but are less toxic compared to their corresponding metal ions. These nanoparticles can be transferred through aquatic food webs, but further investigation is needed on their internalization and toxicity mechanisms for algae.

Summary: Species distribution models are commonly used to predict potential distributions of invasive species. However, niche expansion in freshwater invasive species challenges the reliability of these models. This study investigates the factors influencing niche shifts using multiple sets of environmental variables and found that methodological choices strongly affect niche dynamics metrics, while biological features have a weaker influence. Inappropriate methodological choices can lead to apparent niche shifts, raising concerns about the reliability and interpretation of niche models. The high rate of niche expansion in freshwater invasive species emphasizes the need for objective criteria in selecting variables for niche assessments.

Summary: Climate change has a significant impact on Earth's ecosystems. Invasive species respond to climate change, with ecological and economic implications. Habitat suitability models help assess the potential impacts of climate change on species. The models predict the expansion and shift of suitable conditions for three invasive fish species in Europe under different climate scenarios.

Summary: This study aimed to enhance our understanding of the impacts of alien species on native freshwater megafauna. The research found that 61 alien species caused negative impacts on 44 native freshwater megafauna species, with predation and competition being the most common mechanisms. It is worth noting that data limitations and the complexity of multiple threats make it difficult to fully assess the significance of alien species impacts.

Summary: The increase in cyanobacterial blooms is linked to anthropogenic factors, causing concerns for drinking water companies and water managers due to the toxins produced. Simple, sensitive, and cost-effective analytical approaches are essential for risk assessment and large-scale studies. The development of a method for the multi-class determination of cyanotoxins in fresh water, which can separately report intra- and extracellular toxins, meets validation criteria and helps in risk management.

Summary: Freshwater invasive alien species (IAS) are non-native organisms released into local water bodies, which disrupt ecological processes. Environmental DNA (eDNA) analysis has been effective in detecting IAS, but combining it with geographic information systems (GIS) can enhance efficiency. This paper reviews the use of GIS mapping and eDNA analysis to detect IAS in Southeast Asia, providing a comprehensive approach for future studies.

Summary: This study investigates and analyzes the distribution, diversity, and relationship with environmental variables of freshwater organic-walled algal palynomorphs by developing a training set. By analyzing the properties of water and sediment, as well as climate and catchment characteristics, the indicative value of algal palynomorphs along different gradients is revealed. Reconstruction of pH and electric conductivity for two lakes using the established training set provides possibilities for further non-pollen palynomorph research.

Summary: The study demonstrated that submerged aquatic plants have a higher ability to accumulate mercury compared to natant aquatic plants. Additionally, it was found that chlorides did not have a significant impact on mercury accumulation, while the presence of humic acid in the water environment resulted in a significant decrease in mercury accumulation.

Summary: The distribution of mercury species was studied in the Zaskalska water reservoir near an abandoned cinnabar mine in Czech Republic. The results showed that the mercury from the mine is the major source of mercury in the reservoir. The legal maximum limit for mercury concentration was exceeded during rainy periods, and the dominant form of mercury in sediments was mercury sulphide. The mercury content in fish muscle exceeded the legal limit, posing a health risk. The study highlights the need for legal restrictions on the consumption of piscivorous fish caught downstream of abandoned cinnabar mines.

Summary: This research aimed to advance the standardization technology for commercially cultivated Limnospira. Quantitative methods were established to detect fatty acids as potential chemical markers and immune-enhancing activity. The results showed a significant correlation between fatty acid content and biological activity, and a large variation in fatty acid content and activity among different samples. Therefore, the use of standardization methods is crucial in the production and scientific research of Limnospira to ensure consistency and accuracy.

Summary: Hydric recultivation by flooding abandoned mining pits creates a new habitat for aquatic organisms. The periphyton in the littoral zone of post-mining lakes showed a high diversity, with different species compositions and successional patterns. Calcium ions were found to be correlated with the periphytic mats and should be investigated further.

Summary: Cyanobacterial taxonomy is undergoing rapid changes due to advancements in 16S rRNA gene sequencing and new classification workflows. A study has reconstructed a robust phylogenomic tree using genomic sequences and established a polyphasic classification system for Cyanobacteria. This system incorporates both phylogenomic and phenotypic data to provide useful information for professionals in the field. However, the study also highlights the need for integrating genomic data to conclusively classify a large number of cyanobacterial genera in the future.

Summary: In this study, an epitype of the cyanobacterial genus Microcrocis was proposed based on an environmental sample of the type species M. geminata. Molecular analyses revealed its position within the family Geminocystaceae and its relationship with the genus Merismopedia. The phylogenetic classification was consistent with the unique ultrastructure of parallel thylakoids found in some members of the family. The distinctive morphology of the genus, including its longitudinal division, was also discussed.

Summary: This study evaluated the impact of climate change on fisheries in the Czech Republic by examining changes in water temperature and their effects on fish farming. A model was developed to calculate surface water temperature based on air temperature, and the results showed that there will be a sharp increase in temperature regimes, posing challenges to traditional forms of common carp farming. Adaptation measures will be necessary to mitigate the impact of rising water temperatures.

Summary: The application of modern molecular methods and phylogenetic approaches has led to an explosion in cyanobacterial taxonomy in recent years. This has caused confusion due to the ease of describing new taxa and the pressure to publish a high number of papers. However, upon closer observation, it is evident that most new species are from terrestrial habitats and there is still limited research on certain groups.
