Hydrologic effects on riparian vegetation in a boreal river: an experiment testing climate change predictions
International audience Climate change is expected to alter the magnitude and variation of flow in streams and rivers, hence providing new conditions for riverine communities. We evaluated plant ecological responses to climate change by transplanting turfs of riparian vegetation to new elevations in...

International audience Climate change is expected to alter the magnitude and variation of flow in streams and rivers, hence providing new conditions for riverine communities.
