title: Data from: Phenotypic integration between claw and toepad traits promotes microhabitat specialization in the Anolis adaptive radiation

description: The performance of an organism in its environment frequently depends more
 on its composite phenotype than on individual phenotypic traits. Thus,
 understanding environmental adaptation requires investigating patterns of
 covariation across functionally-related traits. The replicated adaptive
 radiations of Greater Antillean Anolis lizards are characterized by
 ecological and morphological convergence, thus providing an opportunity to
 examine the role of multiple phenotypes in microhabitat adaptation. Here,
 we examine integrated claw and toepad morphological evolution in relation
 to habitat partitioning across the adaptive radiations of Greater
 Antillean anoles. Based on analysis of 428 specimens from 57 species, we
 found that different aspects of claw morphology were associated with
 different perch dimensions, with claw height positively associated with
 perch diameter and claw curvature positively associated with perch height.
 Patterns of integration also varied across claw and toepad traits, likely
 driven by correlative selection for performance on smoother and rougher
 substrates. Finally, rates of evolution differed between claw and toepad
 traits, with claw length evolving faster than all other traits despite
 having no predicted functional importance. Our results highlight the
 multivariate nature of phenotypic adaptation and suggest that phenotypic
 integration across Greater Antillean anoles is driven by fine-scale
 correlative selection based on structural habitat specialization.
