Characterization of European lampreys and fishes by their longitudinal and lateral distribution traits

This study aims to complement existing fish-based assessment approaches by classifying European lampreys and fish species according to their probability of occurrence in six different longitudinal river regions and five types of floodplain water bodies under unimpaired conditions. The main objective...
