Figure 2: Effect of road disturbance on the proportion of total vegetation cover associated with Arbuscular Mycorrhizal (AM) fungi across regions and along temperature gradients. AM vegetation cover was measured along roadsides from 0 to 2 m (red) and in the adjacent vegetation both from 2 to 52 m away from the road (orange) and from 52 to 102 m (green). Mean annual soil temperature was extracted from global maps of soil temperature at a 1 km resolution. The regions are plotted in order from lowest to highest average yearly soil temperature and confidence intervals are represented by the dotted lines. Trendlines come from a partial pooling approach on a linear mixed model (see Methods).
