Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Life on the Edge: Ecosystem Features of Lakes Across a Mountain–Prairie Elevation Gradient in Western Canada

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Ecological transition zones such as mountain elevation gradients can influence the function and productivity of lakes through changes in climatic characteristics and catchment composition (i.e., land use/land cover). However, surveys of limnological features along such ecological transition zones show variable patterns, making it difficult to ...

Environmental DNA Reflects Differences in Freshwater Habitat Use Between Two Pacific Salmonids at Fine Temporal Scales

Environmental DNA, Volume 8, Issue 1, January–February 2026.
A year‐long eDNA survey was conducted in two Canadian rivers to track changes in Chinook and coho salmon freshwater habitat occupancy. eDNA concentrations were aligned with known migratory and spawning patterns, with Chinook signals peaking earlier than coho. These findings highlight eDNA as a temporally sensitive tool for monitoring salmon life stages

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Rice cultivation supports growth and survival of a threatened semi‐aquatic reptile

Ecological Applications, Volume 35, Issue 8, December 2025.
Abstract Integration of agroecosystems and other working landscapes with protected lands and waters is critical to the conservation of Earth's biodiversity. Rice agroecosystems support many species by providing aquatic habitat where natural wetlands have been altered or drained.

Unraveling multipredator impacts in salmon‐bearing rivers using quantitative DNA metabarcoding

Ecological Applications, Volume 35, Issue 8, December 2025.
Abstract Ecological impacts of invasive species are mounting as their numbers and geographic extent continue to increase. Across extensive parts of their range, Pacific salmon (Oncorhynchus spp.) smolts face an expanding gauntlet of nonnative predators during their seaward migration.

Toward Co‐Designed Earth System Models: Reflecting End‐User Priorities in Local Applications From a Modeler's Perspective

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Earth System Models (ESM) are crucial for quantifying climate impacts across Earth's interconnected systems and supporting science‐based adaptation and mitigation. However, not including end‐users, especially decision‐makers representing communities vulnerable to climate change, can limit model utility, increase epistemic risks, and lead to ...
