At the intersection of soundscapes and roads: Quantifying anthrophony's influence on wildlife crossing structure use

open access: yesEcological Applications, Volume 36, Issue 1, January 2026.
Abstract Anthropogenic noise (anthrophony) can have significant negative effects on wildlife, causing both physiological (i.e., increased stress hormone production) and behavioral (i.e., altered anti‐predator behaviors, space use, or diel activity) changes in individuals.

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

open access: yesRiver 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.

Sediment erosion in Francis turbines

open access: yes, 2013
Sediment erosion is a major challenge for run-of-river power plants, especially during flood periods. Due to the high content of hard minerals such as quartz and feldspar carried in the river, substantial damage is observed on the turbine components ...
