Figure S1 a) Lizard richness patterns along 1° latitude bands within the overall range
of China; b) Lizard richness pattern along 1° latitude bands within the boundary of
Oriental Realm; c) Lizard richness pattern along 1° latitude bands within the
boundary of Palaearctic Realm. Empirical range sizes were used for all simulations.
The solid grey lines show the 95% prediction curves sampled without replacement
and the dotted grey lines show the 95% prediction curves sampled with replacement
using the program ‘Mid-Domain Null’ (30000 simulations).

Oriental Realm; c) Snake richness pattern along 1° latitude bands within the boundary
of Palaearctic Realm. Empirical range sizes were used for all simulations. The solid

Figure S3 a) Relationship between lizard latitudinal range extent and range midpoint
within the overall range of East Asia; b) Relationship between lizard latitudinal range
extent and range midpoint within the boundary of Palaearctic Realm; c) Relationship
between lizard latitudinal range extent and range midpoint within the boundary of
Oriental Realm. The straight line shows the simple regression analysis, while the
curved line shows the second degree polynomial model. In all the subplots,
X-coordinates denote the range midpoints of species, while the Y-coordinates denote
the latitudinal range extent of species.
