Sistrurus phylogeny

[Andre Ngo]

        I am presently undertaking an analysis of the phylogenetic
relationships of the "ground rattlesnakes", genus Sistrurus, and would like to
check whether any of you know of anyone who is either presently working on
them, or who has produced an acceptable (well supported) phylogeny of these
animals.

                Thank you all in advance for your responses,

                                        Andre Ngo
