Figure 3. Fitted I-spline functions of significant predictors represented in the ecosystem (coloured orange), abiotic (coloured brown), and biotic (coloured green) response models. Each panel corresponds to an individual predictor with the x-axis (predictor) showing the native unit scale and the y-axis (f(predictor)) corresponding with GDM transformed values. The maximum height of each predictor curve corresponds with the amount of the ecological change along that predictor gradient. It indicates the importance of each predictor, while holding other variables constant (Mokany et al. 2022). Curve slope represents change in dissimilarity and how it shifts with increased predictor values. Error ribbons were created through bootstrapping and represent +/- one standard deviation of predicted spline functions (Fitzpatrick et al. 2024). Predictor data are described in S1.
