Fig.5 Structural equation model (SEM) linking each resource
availability to plant (a) abundance and (b) species diversity in
shrubland, (c) abundance and (d) species diversity in shrub layer of
woodland, and (e) abundance and (f) species diversity in tree layer of
woodland. The numbers above the arrows indicate path coefficients (λ,
standardized regression coefficients), and the strength of path
coefficients is indicated by the width of the arrows. Solid black lines
indicate significant (P < 0.05) pathways and dashed
black lines indicate non-significant (P > 0.05).
R2 values represent the proportion of variance
explained for abundance and species diversity. For abbreviations, see
Material and Methods and Table 2.
