The Long‐Term Effects of Created Habitat on Native Salmonids in a Small Headwater Stream in the Boreal Forest

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Stream improvement projects are common across North America. The goal of these projects is usually increased fish production, but long‐term monitoring is rarely conducted to determine if these goals are met. We examined how a constructed pool‐riffle sequence influenced density and biomass of native salmonids (brook trout (Salvelinus fontinalis)

Grow With the Flow? Impact of Experimental Floods on Riparian Vegetation in an Alpine River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Experimental floods have been proposed as a measure to mitigate effects of river flow regulation, primarily vegetation encroachment, streambed colmation, and loss of bed and channel mobility. In this study, we investigated the short‐ and long‐term biogeomorphic effects of an experimental flood programme conducted in the Spöl River (Swiss Alps)

Woody cover and geology as regional‐scale determinants of semi‐arid savanna stability

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Savannas are vital for global biodiversity and carbon storage, yet their responses to climate change and human activity remain uncertain. Using remote sensing time series and Bayesian Linear Models, we show that drought resistance and resilience vary regionally, shaped by complex interactions between geology, woody cover, fire regimes, past climate ...
