Scaling Up Species Delimitation From DNA Barcodes to Whole Organelle Genomes: Strong Evidence for Discordance Among Genes and Methods for the Red Alga Dasyclonium

open access: yesMolecular 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 Fixation Potential in Bathypelagic Sediment of the Ice‐Covered Arctic Ocean Revealed Through Long‐Term Stable Isotope Incubations

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
We sampled five locations of deep‐sea surface sediments in the central ice‐covered Arctic Ocean and documented diazotroph communities and nitrogen fixation potential. The findings considerably extend the known biome of marine nitrogen fixation and raise the question of the significance of low but potentially widespread nitrogen fixation in deep‐sea ...

Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition

open access: yesEnvironmental 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.

Biodiversity in mountain soils above the treeline

open access: yesBiological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Global Change Likely to Promote the Expansion of the Quagga Mussel (Dreissena bugensis) in Europe

open access: yesJournal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim Invasive aquatic species are a pressing concern for environmental managers due to their significant impacts and high eradication costs. The Ponto‐Caspian region is a notable source of aquatic invasive species, with over 40 invaders currently affecting freshwater ecosystems throughout Europe.
