Riverine Migration Success of Salmonid Smolts Following Their Entrainment in a Hydropower Off‐Channel Diversion in an Upland River

River Research and Applications, Volume 42, Issue 6, Page 1272-1282, July 2026.
ABSTRACT Salmonid fishes typically express anadromy. During their juvenile riverine emigration, their downstream movements can be inhibited by hydropower schemes that entrain fish in their intakes. Here, the riverine migration success of smolts of brown trout Salmo trutta (“trout smolt”) and Atlantic salmon Salmo salar smolts (“salmon smolt”) was ...

The effects of breath holding during high‐intensity land‐based ergometry in swimmers

Physiological Reports, Volume 14, Issue 13, July 2026.
Abstract The aim of this study was to compare cardiorespiratory responses during high‐intensity land‐based exercise between free‐breathing and breath‐holding conditions in swimmers. Twenty varsity swimmers (20 ± 2 years, 10 females) performed 20 s bouts of simultaneous arm and leg ergometry exercise at high intensity (total power output = 606 ± 76 W ...

Life Cycle Environmental Impacts and Socio‐Economic Implications of Tidal Electricity Generation and Storage in the UK

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
If tidal electricity generation and storage replaced natural gas and battery storage by 2050, it could reduce the climate change impact of UK grid electricity by 71%, saving up to 4.4 Mt CO2 eq./y. Most other environmental impacts would be reduced by up to 24%. However, high costs and low public acceptability hinder its deployment. ABSTRACT Tidal range
