The phylogenetic relationships among anoles have been much studied and difficult to unravel. Most work has focused on the Caribbean anoles, leaving the phylogenetic relationships among mainland anoles and the majority of Norops (beta Anolis ) species virtually uninvestigated. A classification of...
Previous systematic studies of the Bufo peltocephalus Group based on morphology and one on molecular data support the monophyly of this lineage of West Indian toads. Herein, additional phylogenetic evidence supporting the monophyly of the group is presented. Osteological, external morphological,...
