Spatial priorities for freshwater biodiversity conservation in light of catchment protection and connectivity in Europe

simultaneously considers the conservation status, range-restriction of the species, and the uniqueness (endemicity) of species assemblages, and which also evaluates the effects of current protection and hydrological connectivity of catchments. Our results showed high conservation Fig 2.
