Table 2. Importance (Imp.) of IBD, IBRTerrain,
IBRHabitat, IBI and IBE on explaining population genetic
differentiation (FST) as assessed through GDM (compare
Table S20, Figs. S4-S10); Imp.-1/-2/-3 give models where, sequentially,
the respective explanatory variable(s) contributing least to model fit
were removed (indicated by empty space). Note that models may fail to
fit if relationships between FST and (some) explanatory
variables are weak (indicated by “/”).
