Phenetic Relationships. PDF/Acrobat file     SoulĂ©, M.E.

This report discusses an attempt to apply the methods of numerical taxonomy in assessing the phenetic relationships of closely related populations of a lizard, the side-blotched lizard (Uta stanburiana, sensu lato) on 18 islands in the Gulf of California and from two mainland populations, Tonopah, Nevada, and Bahia de los Angeles in Baja California, Mexico (Fig. 1). Certain methodological questions are raised and discussed. These include the problem of growth in comparative studies, the effect of using a small number of correlated characters in such a numerical analysis, and the appropriateness of a two-dimensional hierarchy to represent what may be a non-hierarchical pattern. The biogeography of the Gulf of California region, and the evolutionary trends of the sideblotched lizards on the Gulf islands are discussed elsewhere (Soule and Sloan, 1966; Soule, 1966).
