Figure 4: Variance components and fitted relationships between
resident diversity, as indicated by resident effective species richness
(ESR), and experimental treatments and consequent invader cover.Left panel (a): Variance components for the best
performing model of resident ESR (sqrt-transformed). Point estimates are
set on a standard deviation scale and represent the medians of the
posterior distributions. Bars present 95% (wide) and 68% (narrow)
credible intervals. Variance components were produced through Bayesian
multilevel modelling. Point estimate scale varies compared to Fig 2a and
3a due to the square-root transformation of resident ESR.Right panels (b-d): Fitted relationships between
resident diversity (square-root transformed) and b) total invader cover
(scaled); c) growth season (separated by succession stage) and d)
disturbance. Envelopes represent 95% confidence intervals. Points
represent partial residuals. Relationships are fitted from the best
performing linear mixed-effects models.
