Fig. 2: RPE ratio interactions with soil properties.
From: Positive rhizosphere priming accelerates carbon release from permafrost soils
Relationships between RPE ratio of active layer and permafrost soils and soil carbon content (a), nitrogen content (b), carbon to nitrogen ratio (c) and cumulative SOM-derived CO2 flux (d) with paired comparison between active layer and permafrost soils (e). Error bars and ribbons represent 95% confidence intervals on mean RPE ratio for each soil from days 0 to 370. Only the fitted lines of significant (p < 0.05) relationships are displayed. In insert box-plot (e) the box represents the interquartile range (IQR), spanning from the first quartile (Q1) to the third quartile (Q3). The bold horizontal line within the box denotes the median. Whiskers extend to the smallest and largest values within 1.5 times the IQR from Q1 and Q3. Data points beyond this range are plotted as outliers.
