Restoration using flow deflectors: a question of fine‐scale spatial layout in headwater stream beds
Restoration Ecology, Volume 33, Issue 7, September 2025.Current European Union objectives for 2030 aim to restore ecosystems to halt biodiversity loss. Here, we studied the consequences of headwater stream restoration by placing large wood in the streambed to act as flow deflectors. We hypothesized that these flow deflectors would create a fine‐scale spatial arrangement of habitats, fostering a diverse and ...

Ecological pathways connecting riverine drought to community change across space and time
Ecological Monographs, Volume 95, Issue 3, August 2025.Abstract Climate change is intensifying droughts via reduced snowpack and accelerated snowmelt in high mountains globally, altering community structure in snow‐dependent rivers. To predict impending ecological change in rivers, we must understand the importance of the abiotic and biotic mechanisms connecting hydrologic change to biodiversity change and
