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.
