Strengthening the link between climate, hydrological and species distribution modeling to assess the impacts of climate change on freshwater biodiversity

► We model the hydro-climatic impacts of climatic change on riverine fish distribution. ► The framework combines statistical downscaling and fish species distribution modeling. ► The downscaling framework explicitly models fish species habitat suitability. ► Most fish species in SW France should expand their geographical range in the future. ► The proposed methodology has a wide range of applications for climate change impact studies.
