Fig 1.
Our limb measurements included hand length (from the center of the wrist joint to the tip of longest digit measured on the dorsal side), antebrachium length (from apex of the elbow joint to center of the wrist joint, on the dorsal side), brachium length (from the axilla to apex of the elbow joint), thigh length (from the point in which the hind limb enters the body to the apex of the knee); crus length (from the apex of the knee to the ankle joint); and foot length (from the center of ankle joint to the tip of longest digit, toe four, measured on the dorsal side).

Body and total hind limb lengths.
Pad-bearing gecko (grey) and anole (black) residuals from a single regression (A) and residuals from clade-specific regressions (B). Variation in residuals is shown in inserted scatter plots and horizontal bar graphs.
Fig 3.
Perche types used by geckos observed in Queensland, Australia.
The number of individual geckos observed using vegetation (dark gray), rocks (medium gray), and the ground (light gray) are shown.
Fig 4.
Perch heights and perch diameters of Caribbean anole ecomorphs and arboreal geckos from Queensland Australia.
Polygons indicate ranges for anole ecomorphs [10, 13, 54]. Note that many geckos use perch heights and diameters that are similar to those used by anole ecomorphs. Symbols are: CG = crown giant, TC = trunk-crown, TW = twig, TG = trunk ground, GB = grass bush, Gehyra spp. (black circles), Oedura spp. and closely related Amalosia rhombifer (white triangles), Pseudothecadactylus australis (blue square), Strophurus spp. (grey circles), non-ecomorph (unique) anole species (X), and Anolis porcus from the subgenus Chamaeleolis (+).
Fig 5.
Relationships between relative limb length and perch diameter.
Regression residuals of combined geckos and anoles (A), clade-specific regression residuals for anoles only (B), and geckos only (C). All plots display the PGLS correlation line, Pagel’s λ, and slope p-values. Symbols are: CG = crown giant, TC = trunk-crown, TW = twig, TG = trunk ground, GB = grass bush, non-ecomorph (unique) anole species (X), Anolis porcus of the subgenus Chamaeleolis (+), Gehyra spp. = G, arboreal Oedura spp. and closely related Amalosia rhombifer = O, Pseudothecadactylus australis = P, Strophurus spp. = S. Plot A illustrates a positive correlation with anole data in red and gecko data in black. Plot B illustrates the positive correlation for anoles only. Plot C displays the negative correlation for geckos only.
Fig 6.
Negative correlation between residual thigh lengths and the proportion of vegetation use for each species.
Brachium segment length showed a similar pattern. Symbols are: arboreal Gehyra spp. (black circles), arboreal Oedura spp. and closely related Amalosia rhombifer (white triangles), rock-dwelling Oedura spp. (red diamonds), arboreal Pseudothecadactylus australis (blue square), and arboreal Strophurus spp. (grey circles). Line = PGLS model with estimated Pagel’s λ and slope p-values.
Fig 7.
Negative correlation between perch angle and total hind limb length.
Residual thigh, crus, brachium, antebrachium, and total fore segment lengths had a similar pattern. Symbols are: arboreal Gehyra spp. (black circles), arboreal Oedura spp. and closely related Amalosia rhombifer (white triangles), rock-dwelling Oedura spp. (red diamonds), arboreal Pseudothecadactylus australis (blue square), and arboreal Strophurus spp. (grey circles). Line = PGLS model with estimated Pagel’s λ and slope p-values.
