Fig. 3: Effects of dominant environmental change drivers on species richness, evenness, biomass, and biomass proportion of understory plants.
From: Environmental change shapes understory plant diversity and dominance in boreal forests
a Changes in species richness; b changes in species evenness; c changes in biomass; d changes in biomass proportion. Red line shows the model-predicted mean; gray shaded band shows bootstrap 95% confidence intervals. Solid and dashed lines represent the significant (P ≤ 0.05) and nonsignificant (P > 0.05) relationship. Slope estimates are partial dependencies derived from the most parsimonious model introduced (details in Supplementary Tables 1 and 2). The dominant environmental change driver was selected based on the highest r² value. The significance (P) is presented for each term tested. BP: biomass proportion. ΔTemS: temporal changes in annual temperature seasonality; ΔTem: temporal changes in annual temperature; ΔCMI: temporal changes in annual climate moisture index; ΔCND: temporal changes in cumulative nitrogen deposition; ΔSA: decadal changes in annual solar radiation. We use two-sided t-test to calculate P-values.
