Fig. 1: Greenhouse gas (GHG) saturation in the 31 sampled lakes.
From: Trajectories of freshwater microbial genomics and greenhouse gas saturation upon glacial retreat
A GHGs (log-scale) separated into 3 subsets based on their distance to the nearest glacier. The bottom and top of the box are the 25th and 75th percentile (the lower and upper quartiles, respectively), and the band near the middle of the box represents the median; the upper whisker extends to 1.5 * inter-quartile range (distance between the first and third quartiles). B, D Results from generalized additive models (GAMs) for CH4 saturation along the chronosequences with partial effect splines (as shown by red lines) for significant variables including distance from glacier (B), dissolved organic carbon (DOC; C) and total nitrogen concentrations (TN, D). Standard errors are indicated by dotted lines while data points are shown by open circles. GAMs partial effect splines for significant variables modeling CO2 saturation are shown in Supplementary Fig. 2.
