Table 1.
Short and long primers used for gene shuffling. The positive control used for q-PCR is also listed.
Figure 1.
Co-inertia analysis of the chemical and microbial data.
(1A) K-means clustering output. Each of the eight groups is numbered inside square boxes and the 39 samples are indicated and linked to the boxes. The ellipses represent group clusters based on K-means clustering. (1B) Main chemical vectors that affect sample ordination. The lengths of the vector arrows represent the influence of the given parameter on the co-structure of the CIA. Anions and cations are represented by their chemical symbols and organic acids are given as: Prop (propionate), Ox (oxalic acid), Ace.Glyc (acetate-glycolate), MSA (methylsulfonic acid) and Glut (glutaric acid). (1C) Probes showing the greatest influence on the ordination. The lengths of the vector arrows represent the influence of the given parameter on the co-structure of the CIA.

Distribution of cyanobacterial taxa between Groups 1 and 2.
Figure 4.
Metabolic potential of the snowpack.
The proportion of each type of analyzed metabolism (aerobic, anaerobic, facultative and unknown) is given for each of the eight groups.

Linear correlation between merA gene copy number (copies.ngDNA−1) and BioHg concentrations (log ng.L−1).
Crosses represent samples from Group 2, and circles samples from Groups 3 and 7.
