Dam Submergence Flows: An Environmental Flow Prescription Designed to Aid Migratory Fish Passage

River Research and Applications, Volume 42, Issue 1, Page 19-29, January 2026.
ABSTRACT As part of a holistic ecosystem‐focused set of unified flow prescriptions, natural spring flood events were enhanced with releases from an upstream reservoir on the Cape Fear River in North Carolina (USA) to submerge a series of low‐use, low‐head lock‐and‐dam structures for anadromous fish to move upstream.

The Record of the Last Sturgeons Caught in the Po River (North Italy) Tells a Cautionary Tale of Reasons of Their Silent Disappearance

River Research and Applications, Volume 42, Issue 1, Page 277-283, January 2026.
ABSTRACT Three sturgeon species—the common European (A. sturio), beluga (H. huso), and Adriatic sturgeon (A. naccarii)—coexisted in the Po River Basin until the mid‐1970s, representing centuries of bio‐cultural heritage for northern Italy's riverine communities.

A Mark‐Recapture Estimate of the Number of American Eels Arriving at the Lowermost Barrier on the Wolastoq|Saint John River, Canada

River Research and Applications, Volume 42, Issue 1, Page 40-59, January 2026.
ABSTRACT The upstream migration of juvenile American eels (Anguilla rostrata) is frequently obstructed by dams and other in‐stream barriers, leading to habitat loss and fragmentation, factors that are believed to contribute to the species' population decline.

Integrated Use of Oxidative Stress and Histological Biomarkers of T. tinca as Indicators of 17‐Alpha‐Ethynylestradiol Exposure

Environmental Toxicology, Volume 41, Issue 1, Page 49-67, January 2026.
ABSTRACT The potential adverse effects of 17‐alpha‐ethynylestradiol (50, 100, and 500 μg EE2/kg b.w., for 30 days) on tench ( Tinca tinca ) were evaluated by integrating biomarkers including physiological (hepato‐somatic index, spleen‐somatic index, and hematocrit), oxidative stress (catalase, glutathione peroxidase, and glutathione reductase ...

Bridging Ecology and Geosciences in Riverscapes: Implications for Process‐Based Restoration

Ecological Research, Volume 41, Issue 1, January 2026.
In this paper, we synthesize studies that integrally examine geological and ecological processes across different scales and components of riverscapes, including geohydrological processes. Finally, we identify both scientific and practical challenges that must be addressed to bridge the gap between basic‐science implications and their implementation in

Development of a High‐Resolution MNP Marker System for Aquatic Biodiversity Monitoring: A Case Study With Schizothorax prenanti in the Yangtze River

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Effective monitoring of aquatic biodiversity is critical for conservation, yet current approaches such as mitochondrial COI barcoding and microsatellite markers exhibit limitations in resolution, sensitivity, and scalability, particularly for detecting low‐abundance or degraded DNA in mixed aquatic samples.
