Estimates of Spawning Stream Contributions to an Imperilled Bull Trout Metapopulation Utilizing Otolith Geochemistry and Redd Counts

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Migratory fish species have experienced substantial declines throughout aquatic habitats, but actions to manage and conserve migratory species require a better understanding of the relative contributions of local populations to the metapopulation.

Influence of Oscillating Flow on Hyporheic Zone Development [PDF]

Groundwater, 2011
The hyporheic zone is an ecologically important ecotone that describes the extent to which nutrient‐rich surface waters penetrate the shallow subsurface adjacent to a flowing surface water body. Although steady‐state models satisfactorily explain the incursion of surface water into the subsurface as a function of head gradients developed across ...

Flume Experiments With Refractive‐Index Matched Sediment Revealing the Impact of Two In‐Line Channel‐Spanning Logs on Hyporheic Exchange

Water Resources Research
In‐channel wood, a critical component of forested rivers, has the capacity to enhance hyporheic flow. This process facilitates the continuous exchange of gases, solutes, and nutrients across the sediment‐water interface, regulating pollutant transport ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Experimental study of bedform-driven hyporheic exchange

Shui kexue jinzhan, 2014
In order to test the bedform impacts on the hyporheic exchange behavior,the tracer Na Cl is used to test the hyporheic exchanges under four groups of bedforms in a water-circling flume.

Under Surveyed and Under Pressure: Additional Biodiversity Uncovered in the Freshwater Mussels (Unionida: Velesunioninae) of North‐Western Australia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Here, we tested for cryptic diversity within freshwater mussels in north‐western Australia and identified multiple undescribed lineages. Distributional patterns were complex with some taxa displaying evidence of potentially recent long‐distance dispersal whereas others were more restricted in their distributions.

In-stream and hyporheic water quality of the River Esk, North Yorkshire: implications for Freshwater Pearl Mussel habitats [PDF]

, 2013
River systems and their catchments are important for ecological, social and economic reasons. However, the increased and changing usage of these natural environments and resources for anthropogenic benefit have led to degradation in water quality, which ...
