Figure 1.
Topology of Gymnophthalmidae used in the phylogenetic analysis.
Branch colors represent the elongation groups detected using the morphological component (morphPC): less-elongated species are shown in black and more-elongated species in gray. Asterisks represent the subfamilies Rhachisaurinae (*) and Alopoglossinae (**); taxonomy adopted follows [31].
Figure 2.
Relationships between aridity index (logQ) and body elongation (given by morphPC) in gymnophthalmid lizards.
MorphPC = morphological principal component. Symbols represent elongation groups: triangles correspond to the more-elongated species, and squares indicate less-elongated species.
