Fig. 4: Hemisphere-wide patterns of forest types.
From: Positive feedbacks and alternative stable states in forest leaf types
A Empirical map of bimodality in forest types generated from GFBi data. Colors reflect the value of the bimodality index (BI), with red representing BIs < −0.22 (deciduous-dominated forest clusters), blue representing BIs > 0.22 (evergreen-dominated forest clusters), yellow representing BIs from −0.22 – 0 (bistable-deciduous forest clusters) and cyan representing BIs from 0–0.22 (bistable-evergreen forest clusters). B Projected map of bimodality in forest types across the Northern Hemisphere based on random forest modelling. Colors reflect the projected value of the bimodality index (BI), and share the same scale as in A. Predictions in B were made for forest regions (1) above 15 degrees northern latitude, where > 98% of the GFBi data are located, (2) whose environmental conditions well represented by our training data (> 90% interpolation, see Fig. S9A). C Relative frequencies of plot-level relative evergreen abundance in deciduous-dominated, bistable-deciduous, bistable-evergreen and evergreen-dominated regions. Source data are provided as a Source Data file.
