Mesohabitat Evaluation Reveals Variable Abundances and Habitat Choice in Juvenile Atlantic Salmon Across Diverse Habitats in the Main Stem of a Large Sub‐Arctic River

Ecology of Freshwater Fish, Volume 34, Issue 3, July 2025.
ABSTRACT Large main stem rivers typically provide a variety of mesohabitat types, but their abundance, distribution and role in providing habitat for juvenile salmonids have rarely been analysed. The quantity of meso‐scale habitats and their juvenile Atlantic salmon abundance was surveyed in the large sub‐arctic River Teno in northernmost Fennoscandia.

Long‐Term Temporal Divergence in Post‐Drought Resilience Decline Between Deciduous and Evergreen Tree Species

Global Change Biology, Volume 31, Issue 7, July 2025.
Severe drought increasingly threatens the resilience of forest biomes worldwide. Using a tree‐ring database from Canadian forests, encompassing 40,147 trees across 4558 plots and 23 species, we analyzed temporal and spatial patterns of drought resilience.

Tracking landslide sediment: 10Be dilution of detrital quartz in multiple grain sizes following the 2016 Mw 7.8 Kaikōura earthquake, New Zealand

Earth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
We found that the in‐situ 10Be concentration in multiple grain sizes can be correlated to the sediment fluxes derived from geomorphic change detection. Our results show that the magnitude of 10Be dilution relates to landslide volume, post‐seismic hillslope delivery and degree of mixing. Although the 10Be dilution factor has little to no relationship to

Can changes in geomorphic responses to urbanisation be predicted from stormwater outfalls?

Earth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
This study demonstrates that urban stormwater impacts on stream geomorphology are significantly shaped by historical land use and channel stabilisation. These legacy effects influence present channel conditions and constrain future responses to urbanisation.

Potential and constraints of uncrewed aerial vehicle orthoimagery for rivers: A direct comparison with field measurements for mapping boulders

Earth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
Both field and drone surveys are commonly used to map river landforms. Comparing the two, we found that drones consistently underestimated boulder density and coverage by 30%, with the difference best explained by water depth. Abstract Technological advances continue to improve our ability to detect landforms and landscape changes.
