Modelling the current distribution of European diadromous fishes: an approach integrating regional anthropogenic pressures
International audience 1. Twenty-eight diadromous fish species occurred in Europe, North Africa and the Middle East in historical times. Their current distributions were assessed in terms of abundance classes (missing, rare, common and abundant) in 196 basins ranging from Morocco to northern Norway...

Most response curves were easily interpretable since they were related to specific aspects of species' ecology. Anthropogenic variables related to large dams impacted negatively on the distribution of diadromous fishes through the perturbation of river discharge patterns, the loss of river connectivity and the accessibility to essential habitats, particularly for Salmonid species that spawn in headwater streams.
