Hydropower Effluent as a Marine Pollutant; Impacts of River Regulation on Estuarine and Coastal Ecology

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.

Instream Large Wood Enhances the Benefits of e‐Floods in Regulated Mountain Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Environmental high flows, or e‐floods, released from dams are a key management strategy to mitigate the impacts of dam regulation and restore aquatic and riparian habitats. While there is extensive literature on the design and implementation of e‐floods, the role of instream large wood—downed trees, trunks, branches, and root wads—in enhancing

Geomorphic Reach Scale Controls the Availability of Brown Trout Spawning Sites in Große Mühl, An Alpine River of the Bohemian Massif

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Studies on the quantity and quality of the spawning habitats of resident brown trout on the catchment scale of rivers are rare. The spawning habitats of salmonids are locally nested along river corridors and are found throughout variable channel patterns, with a preference for sediments composed of gravel and cobbles and appropriate flow ...

Alpine greening deciphered by forest stand and structure dynamics in advancing treelines of the southwestern European Alps

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Multidecadal satellite observations, like those from Landsat, enable the study of vegetation greenness trends at extensive spatial and temporal scales. Alpine ecosystems show significant increases in vegetation greenness, but the ecological processes driving this greening are less understood.
