Relationship between latitudinal patterns in phylogenetic dispersion—PD (standardised effect size of mean pairwise phylogenetic distance (sesMPD), standardised effect size of mean nearest taxon distance (sesMNTD)) and climatic variables during the Holocene. (A–C) sesMPD and (A) ‘temp_cold’, (B) ‘prec_summer’, (C) ‘prec_winter’, (D–F) sesMNTD and (D) temp_cold, (E) ‘prec_summer’, (F) prec_winter. Here, predictions of the spatio-temporal models (hierarchical generalised additive models hGAMs) for PD are treated as response variables, and predicted values of the spatio-temporal hGAMs for each of the climatic variables are treated as predictor variables (Supplementary text S1B). The black curve is fitted as a ‘loess’ smoother. Climate variables are (A) temp_cold = minimum temperature of the coldest month (°C), (B) prec_summer = summer precipitation (kilogram meter−2 quarter−1), (C) prec_winter = winter precipitation (kilogram meter−2 quarter−1)). Statistical significance of these relationships was tested by a Procrustes randomization test (Table 3).
