Conventional (non-phylogenetic, abbreviated as NP) and phylogenetic (based on phylogenetic independent contrasts, abbreviated as PIC) analyses of large-scale patterns of latitudinal (Lat) and elevational (Elev) range size variation as a function of geographical distribution (adjusted latitudinal mi

Relationships between latitudinal and elevational ranges are analysed using correlations as no causal weight can be attributed to any of these variables. See methods section for additional details.
