Figure 11 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report

Figure 11: Similarity of the native fish species assemblages among lakes sampled by Projet Lac depicted by hierarchical cluster analysis (Sørensen index based on presence/absence of taxa; complete linkage). Lakes joined by shorter branches share a higher proportion of their fish species. Colours indicate river catchments: red = Rhine, green = Rhone, orange = Po, blue = Danube. See Figure 82 for an exploration of factors driving differences in the fish communities among lakes within catchments.
