Adaptive radiation without independent stages of trait evolution in a group of Caribbean anoles

Adaptive radiation involves diversification along multiple trait axes, producing phenotypically diverse, species-rich lineages. Theory generally predicts that multi-trait evolution occurs via a ‘stages’ model, with some traits saturating early in a lineage’s history, and others diversifying later. Despite its multidimensional nature, however, we know surprisingly little about how different suites of traits evolve during adaptive radiation. Here, we investigated the rate, pattern, and timing of morphological and physiological evolution in the anole lizard adaptive radiation from the Caribbean island of Hispaniola. Rates and patterns of morphological and physiological diversity are largely unaligned, belying independent selective pressures associated with structural and thermal niches. Cold tolerance evolution reflects parapatric divergence across elevation, rather than niche partitioning within communities. Heat tolerance evolution and the preferred temperature evolve more slowly than co..., , , # # **Adaptive radiation without independent stages of trait evolution in a group of Caribbean anoles**

## Description of the data and file structure

### Table of Anolis species** **and trait data in this study including:

physiological measurements include: CTmax, CTmin, and Tpref (heat and cold tolerance and thermal preference respectively) are in (⁰C) ± standard error and with sample size in parentheses (N).

categorical variables of ecomorph category (trunk, truck crown, trunk ground, twig, grass bush, crown giant and anoles not belonging to an ecomorph category was deemed to be a ‘unique’ species) and canopy-use category (open vs closed) are used to describe each species. Note the 'unique' species are designated as such because they have no ecomorphological correlates on other Greater Antillean islands.

 Morphological measurements include: snout vent length (SVL;...
