Fig. 2: Changes in the three facets of diversity, functional (FDis), taxonomic (Simpson) and phylogenetic (MPD) across time and climatic gradient.
In a–c each arrow represents a vegetation plot (n = 21), with the tail of the arrow showing the diversity level during the first vegetation census and the head of the arrow the diversity level during the last vegetation census. The slope of the arrow represents the change in diversity across time, so that arrows pointing upwards show increases and downwards decreases in diversity. Arrow colours reflect the absolute change in maximum climatic water deficit (ΔMCWDAbs) experienced by the forest community (colour bar at the bottom of the figure). The X-axis shows the full-term maximum climatic water deficit (MCWDFull covering the 1964–2013 period) and the Y-axis the facets of diversity. d–f Show the average rate of change (coloured dots) and highest density intervals (vertical lines) in the three facets of diversity (ΔFDisr, ΔSimpsonr and ΔMPDr) after grouping the vegetation plots as belonging to dry or wet forest (n = 21). The horizontal dotted line represents no change in diversity with positive values showing increases and negatives values decreases in diversity. The insets on the bottom right corner show the average difference in diversity change between dry and wet forests. Negative average difference values depict a stronger loss in the diversity facet in drier forests in comparison to wetter forests. The posterior highest density intervals (HDI-l: lower; HDI-u: upper) and probability change (Prob) values are also shown.
