Fig. 4 — a Potential structural complexity (SSCI_pot) in forest ecoregions across biomes. SSCI_pot depiction was confined to biomes that were sampled within the frame of this study and are classified as forest or woodland ecoregion according to Olson et al. SSCI_pot of Mediterranean Forests and Woodlands, Dry Broadleaf Forests, Tropical Conifer Forests and Mangroves is not shown here. Predictions are based on the WorldClim2 dataset for the years 1971–2000³³ and were made at 30 arcsecond resolution. b 95% confidence interval of SSCI_pot model predictions. Regions outside the climatic range studied and regions with different soil conditions than our study sites are marked in light blue and yellow, respectively, because we cannot reliably quantify the uncertainty of model predictions for those areas.
