A Multi‐Taxa Approach to Estuarine Biomonitoring: Assessing Vertebrate Biodiversity and Ecological Continuity Using Environmental DNA Metabarcoding in the Rance River (Brittany, France)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

Spatial capture–recapture reveals resource use and declining skipper numbers in Baltic Sea salmon trolling fisheries

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Many populations of Atlantic salmon (Salmo salar) native to the Baltic Sea are endangered. A significant group targeting salmon in this region is the recreational trolling fishery. Due to frequent changes in fisheries regulations and conditions, both salmon conservation and fishers are affected.

Comparison of Environmental DNA Metabarcoding and Trawl Data Highlights Gear Selectivity of Marine Demersal Fish Surveys on the Faroese Plateau

Environmental DNA, Volume 8, Issue 2, March/April 2026.
The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.

Development of eNA Sampling for Early Detection of Pathogens in On‐Farm Water Sources

Environmental DNA, Volume 8, Issue 2, March/April 2026.
We compare four water‐sampling methods for detecting microbial and viral eNA in livestock troughs and show all approaches effectively recover community profiles, supporting flexible, field‐ready surveillance of livestock pathogens. ABSTRACT Early detection of livestock pathogens is critical for mitigating risk and implementing timely control or ...

Contaminant‐Driven Modulation of Environmental DNA and RNA in Aquatic Systems

Environmental DNA, Volume 8, Issue 2, March/April 2026.
This study investigates how lead (Pb) and polyethylene (PE) microbreads influence eDNA and eRNA signals in salmon and eels. While Pb exposure does not interfere with eNA signals, PE microbeads increase eRNA production and slow molecular degradation, prolonging the detection window of eNA in aquatic ecosystems.

Remobilisation of fine sediment from chalk stream gravel beds under flushing flows: A flume experiment

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...
