Fig. 2: Genus α-diversity of bacteria, invertebrates and fish collected from eDNA samples in the Thur catchment.

Maps show the α-diversity of each taxonomic group in (a) spring, (b) summer and (c) autumn. The circles are scaled proportionate to the α-diversity of each group. Grey lines give the sub-catchments Glatt, Necker, and Thur, respectively and the blue arrow shows the direction of flow.
