Figure 1 in Description of a widely distributed but overlooked amphipod species in the European Alps

Figure 1. Distribution map of Gammarus alpinus sp. nov. Red circles indicate lakes with populations of G. alpinus, while white circles indicate sampled lakes without G. alpinus. The figure summarizes data from the literature and our own sampling. The major alpine drainage areas are given in colour (blue = Rhine/North Sea; orange = Danube/Black Sea; green = Rhone, Po/Mediterranean Sea).
