From: Geographical variability of bacterial communities of cryoconite holes of Andean glaciers
Boxplots of pH (a) and oxygen concentration (b) of cryoconite holes in the investigated South American glaciers. The thick lines represent the median, boxes upper and lower limits the 25th and the 75th percentiles respectively, whiskers the 5th and the 95th percentiles respectively, dots represent the outliers and different letters indicate significant differences between glaciers at post-hoc tests.
