Summary: Microbial taxon-taxon co-occurrences reflect potential relationships within a microbial community, influenced by environmental factors. Using a Modified Liquid Association method, over 1000 taxon-taxon co-occurrences highly correlated with environmental factors were detected in Nan Lake, China. These co-occurrences, known as environment dependent co-occurrences (ED_co-occurrences), reveal a unique network showing specific relationships between taxa and environmental parameters.

Summary: This study examined the abundance of four ecologically relevant novel cyanophages in a tropical urban lake in Singapore. The results showed that host cell fraction cyanophages were more abundant than free cyanophage particles, indicating high levels of infection and rapid dispersal. The study also revealed that pH and rainfall may be key factors driving shifts in both cyanophage and cyanobacteria populations.

Summary: In this study, a potential new species of Microsporidia belonging to the Crispospora genus was discovered to infect the rotifer Kellicottia with high prevalence (42.5%) in Lake Aydat, France. This finding suggests that Microsporidia could have a significant impact on the regulation of rotifer populations in lakes.

Summary: Our study found that in warm tropical waters, temperature has little impact on the abundance of V. vulnificus, while fluctuations in salinity caused by rainfall become the main controlling factor. This suggests the presence of a rainfall-driven seasonal cycle in V. vulnificus abundance in the tropics, which is opposite to the temperature-driven cycle in higher latitudes. However, the stochasticity of rainfall and its nonlinear, indirect effects on V. vulnificus concentration mean that high abundances can occur at any time and location in the canal, making it challenging to predict the pathogen's concentrations at a high temporal or spatial resolution. Nevertheless, the variability in canal-wide average concentrations can be partially explained by a few variables reflecting the magnitude of freshwater input, indicating that the relative risk of exposure to this pathogen could be predicted as an average for the system.

Summary: This study evaluated the impacts of barriers, including dams, on aquatic diversity, finding that downstream areas of dams had higher mussel diversity than dam removal sites. Mussel assemblages were influenced by dam type and downstream gradient. Substrate classes and total suspended solids were identified as important predictors of mussel assemblages.

Summary: Microbes in urban estuaries can be greatly affected by seasonal changes and rainfall disturbances, leading to shifts in microbial assemblages and changes in nitrogen levels. In this study, researchers used molecular barcoding and microscopy to analyze microbial communities in an urban estuary. The results showed that the extent of urbanization and the presence of rainfall can significantly impact the microbial assemblages and increase the concentrations of dissolved inorganic nitrogen.

Summary: Most lake whitefish populations in Lake Michigan are experiencing declines due to low recruitment levels, but the stock in Green Bay is thriving with consistent recruitment. A survey over three years found high densities of lake whitefish larvae in offshore and nearshore environments. Factors influencing larval densities include offshore expansion and warmer, more productive waters.

Summary: This study provides new insights into microbial diversity and biofilm structure on plastic microspheres in lake waters. The presence of eukaryotic core members and their relationship with biofilm-forming bacteria on plastic microspheres were investigated for the first time. The study also suggests that plastic microspheres may serve as potential vectors for the dispersal of harmful organisms and antibiotic resistance genes.

Summary: Escherichia coli can survive in sand for prolonged periods, with different genetic subgroups showing varying degrees of survival. The availability of carbon and nitrogen, as well as competition with indigenous microbial communities, are major factors influencing the survival of E. coli. This study highlights the importance of long-term-surviving populations of E. coli in sand and the potential impact of nutrient availability on their persistence.

Summary: Current monitoring for fecal pollution does not account for persistent E. coli populations in freshwater sand, which can result in higher concentrations in water when no threat to human health is present. This work examined the drivers for persistent E. coli populations in sand to aid beach management techniques. The addition of carbon and nitrogen is crucial for the survival of E. coli in freshwater beach sand.

Summary: Managing water quality issues at urban beaches is challenging due to various sources of pollutants. This study used high-resolution data and a hydrodynamic model to predict bacterial concentrations at nearby beaches. The results suggest that regional fecal pollution does not coincide with elevated E. coli levels, while localized contamination likely drives E. coli levels at beaches.
