Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

How the Physical and Chemical Properties Affect the Heavy Metal Content in Surface Water in Different Types of Peatlands

Land Degradation &Development, Volume 37, Issue 13, Page 9254-9265, 15 August 2026.
ABSTRACT Only ~3% of the global land surface is covered by peatlands, yet more than one‐third of global soil carbon is stored in these ecosystems and contaminant filtration can be provided. The extent to which peat humification (Fibric–Hemic–Sapric) is linked to dissolved heavy metals in peatland surface waters has remained poorly quantified at a ...

Anaerobic Corrosion Phenomena of Cast Iron and Copper in Artificial Groundwater at Elevated Temperature

Materials and Corrosion, Volume 77, Issue 8, Page 1262-1277, August 2026.
This study examines corrosion of copper and cast iron as candidate canister materials for high‐level radioactive waste disposal in contact with bentonite suspension. The influence of three electrolyte compositions on corrosion behavior under repository‐relevant conditions is assessed.

Classification and Conceptualization of Karst Recharge Processes Through Spectral and Change Point Analysis of Drip Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Karst aquifers are notoriously heterogeneous, making it challenging to characterize recharge dynamics using traditional, static indicators. Percolating (drip) water records, when analyzed at high temporal resolution, offer insights into flow mechanisms in karst vadose zones.

Effects of model complexity on karst catchment runoff modeling for flood warning systems

Journal of Hydrology X
Severe flood events are deemed more frequent in the near future with a changing climate. Headwater catchments, especially when karstified, exhibit a pronounced susceptibility to swift and substantial responses to precipitation events, leading to flooding.

Conserving the World's Specialist Riverine Birds

WIREs Water, Volume 13, Issue 4, July/August 2026.
Specialist riverine birds constitute a diverse bird group globally, highly adapted to rivers and streams. They are at risk from multiple threats to rivers, riparian zones and river catchments including impoundment, hydropower and abstraction; land‐use changes including urbanization and agricultural intensification; traditional and emerging pollutants ...

Monitoring of Polychlorinated Biphenyls in the Transboundary Ile River and Characteristics of Its Transformations Along the River’s Discharge

Applied Sciences
This study presents the level of polychlorinated biphenyl (PCB) pollution in the transboundary Ile River in 2015, 2018, 2019, 2023, and 2024. PCB contamination of water, as well as the presence of a large number of individual congeners, including ...
