From: Nutrient resorption or accumulation of desert plants with contrasting sodium regulation strategies
Boxplots of nitrogen (N), phosphorus (P), potassium (K), sodium (Na), calcium (Ca) and magnesium (Mg) resorption efficiency among plant groups (corrected for mass loss). The continuous line within each box shows the average, and error bars show 10th and 90th percentiles. Outliers are represented by small solid circles. Different letters above error bars represent significant different (ANOVA, P < 0.05). The gray dashed lines show 0% resorption. The red dashed lines represent global averages corrected with mass loss (Vergutz et al.5). Independent two sample t-test was used for statistical comparisons between this study and global averages, N.S, * and ** represent difference at P > 0.05, P < 0.05 and P < 0.01 level respectively. One sample t-test was used to assess the RE from 0% resorption efficiency. ★, ★★ and ★★★ represent difference at P < 0.05, P < 0.01 and P < 0.001 respectively.
