The Relationships of the Anolis crislatellus Species Group: Electrophoretic Analysis

Anolis cristatellus is a widespread, familiar lizard of the Puerto Rico Bank, comprised of Puerto Rico and associated islands to the east including all the Virgin Islands (except St. Croix). Several other species on Puerto Rico or adjacent islands have, at times, been considered conspecific with A. cristatellus. These have been placed in the A. cristatellus species group by Williams (1976) in his taxonomic and evolutionary summary of West Indian anoles. In this paper we present data from starch gel electrophoresis on a variety of protein systems to analyze aspects of geographic variation within A. cristatellus and to discuss the relationships of the species in the group. Detailed discussion of heterozygosity within populations will be presented in a separate paper dealing with the entire anoline fauna of the Puerto Rico Bank.
