Environmental Microbiology, Volume 27, Issue 10, October 2025.The aquatic microbiome can influence cyanobacterial harmful algal blooms. Abundances of genes and transcripts for phosphorus acquisition, denitrification and nitrogen fixation were higher upstream, whereas in Lake Erie genes and transcripts for microcystin production were higher.

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.ABSTRACT Molecular sequence data have become a ubiquitous tool for delimiting species and are particularly important in organisms where morphological traits are not informative about species boundaries. A range of statistical methods have been developed to derive species limits from molecular data, for example, by quantifying changes in branching ...

Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition
Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.We used untargeted metabolomics to identify differences in the compounds exuded into culture media by three strains of M. aeruginosa grown on three N substrate treatments (NO3−, NH4+, and urea). Results showed that the usage of different N substrates changes the exometabolome of toxic and non‐toxic strains of M. aeruginosa.

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.In the English Channel, the main environmental variables were SPM, POM, PIM, NO2−/NO3+ and salinity in spring and salinity, SPM, Si and Chl‐a in summer. Most of the spring communities had a higher proportion of Bacteroidetes and Proteobacteria, while most of the summer communities had a higher proportion of Proteobacteria, Bacteroidetes, Actinobacteria,

Ecology of Freshwater Fish, Volume 34, Issue 4, October 2025.ABSTRACT Environmental and biological factors strongly shape fish diets, yet little is known about such influences in flooded Karst Dolines of the Neotropical region. This study examined the diet of Deuterodon luetkenii and assessed its temporal and ontogenetic variation in Lagoa Misteriosa, a karstic lagoon. Fish were sampled bimonthly over 1 year and

Double Trouble: Aquatic Invasive Plants Can Promote Mosquitoes
Ecology Letters, Volume 28, Issue 10, October 2025.ABSTRACT Human activities continue to facilitate biological invasions, profoundly impacting our environment and economy. Plants and insects constitute the majority of invasions to date, with facilitative links established between them, particularly in terrestrial habitats.

The FEBS Journal, Volume 292, Issue 20, Page 5439-5456, October 2025.This study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...
