Lizards in an Evolutionary Tree

The Greater Antillean ecomorphs are renowned for convergence of entire communities, with the same set of ecomorphs evolving repeatedly. The mainland, the Lesser Antilles, and the unique anoles of the Greater Antilles are primarily one of non-convergence, both internally and with the ecomorph radiations. This chapter examines the hypothesis that convergence among the Greater Antillean ecomorphs and non-convergence with the other anole faunas stems directly from similarities and differences in the adaptive landscapes they occupy. It first examines patterns of ecomorph occurrence and evolutionary diversification on species-poor islands in the West Indies to see if any general conclusions can be made about the anole adaptive landscape in the West Indies. The chapter then explores non-convergence in the Lesser Antilles, among the Greater Antillean unique anoles, and on the mainland, and explains why evolution may have gone in different directions in these areas.

Keywords:   Greater Antilles, convergence, Lesser Antilles, non-convergence, Greater Antillean ecomorphs, adaptive landscapes, anole faunas, West Indies, unique anoles
