Fig. 3. Composition of the bacterial community on differently colored snowfields and in freshwater sampled at two geographically distant locations in the Austrian Alps.

Taxonomic assignments were conducted at genus level. Bar charts represent the fraction of abundant taxa in the bacterial community with a relative abundance ≥0.1% in the whole dataset. Sampling site A: Rottenmanner Tauern: sampling site B: Seetaler Alpen. Labels and the relative abundances of highly abundant taxa (>10% rel. abundance) are included in the respective bar chart.
