Effects of Historical Isolation and Current River Fragmentation on the Genetic Structure of a Freshwater Fish

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
We investigated how historical isolation and contemporary fragmentation shape genetic structure in Phoxinus bigerri across northern Spain. Microsatellite data reveal strong among‐catchment differentiation driven by historical processes, alongside recent bottlenecks and within‐catchment structuring associated with barrier density.

Fish Migration Through Ship Locks at the Danube River, Austria

open access: yesRiver Research and Applications, Volume 42, Issue 9, Page 1904-1917, November 2026.
ABSTRACT Longitudinal connectivity in the Austrian section of the Danube has improved over the last three decades thanks to the progressive installation of fish passage facilities at hydropower plants. However, navigation locks which are present at all barrages remain poorly quantified with respect to their role in fish migration.

Beyond Dams: Reservoirs as a Lens Onto the Hydrosocial Cycle

open access: yesWIREs Water, Volume 13, Issue 6, November/December 2026.
Synthesizing literature on reservoir inflows, outflows, and operations reveals hydrosocial complexities of water management, which are often overlooked in critical social scientific scholarship on dams. ABSTRACT There is a need for more social scientific scholarship on reservoirs.

Imbalanced Gray‐Green Infrastructure Closely Parallels Extreme Rainfall‐Flood Resilience Inequality Between Mainstream and Tributary Cities in the Pearl River Basin, Southern China

open access: yesEarth's Future, Volume 14, Issue 11, November 2026.
Abstract Climate change and rapid urbanization are intensifying flood risks, making unequal gray‐green infrastructure (GGI) provision a growing concern for extreme rainfall‐flood resilience (ERFR). However, how GGI inequality corresponds with ERFR differences between mainstream and tributary cities remains insufficiently understood.

DataSheet1_Trade-Offs in the Water-Energy-Ecosystem Nexus for Cascade Hydropower Systems: A Case Study of the Yalong River, China.docx

open access: yes, 2022
The hydropower system’s water-energy-ecosystem nexus (WEEN) has gained particular focus in the last years. The water-use trade-offs between hydropower and ecosystem maintenance are complex and variable for cascade hydropower systems, leading to ...

Beyond Precipitation Deficit: Driver‐Based Classification of Hydrological Droughts in an Alpine Basin

open access: yesWater Resources Research, Volume 62, Issue 11, November 2026.
Abstract Hydrological droughts in mountain basins can arise from different combinations of precipitation deficits, snow accumulation and melt anomalies, and seasonal storage conditions. Here, we develop a deterministic, locally calibrated framework to classify recurrent hydro‐meteorological pathways associated with streamflow drought onset in the Upper

Investment timing and optimal capacity choice for small hydropower projects [PDF]

open access: yes
This paper presents a method for assessing small hydropower projects that are subject to uncertain electricity prices. We present a real options-based method with continuous scaling, and we find that there is a unique price limit for initiating the ...
