RESEARCH IN PROGRESS

Systematic Studies: Systematics of Crotalus lepidus (North American rattlesnake); systematics of Stenorrhina freminvillii and S. degenhardtii (Mesoamerican colubrid snakes).

Ecological Studies: Population structure and dynamics of five species of teiid lizards, three species of iquanid lizards, two species of skinks, one gecko species, three species of rattlesnakes, and several other species of snakes. This research is primarily being done on Indio Mountains Research Station.

Biogeography and conservation of Mesoamerican (Mexico and Central America) ecosystems, especially tropical vegetation formations and their inclusive herpetofaunas. Biogeographical analysis of Central Mexico with Aurelio Ramírez-Bautista and his students at Univ. Autónoma de Hidalgo, Mexico. Ecogeographic and conservation studies with Larry David Wilson, Vicente Mata-Silva, Eli García-Padilla, and Dominic DeSantis on the herpetofauna of Mesoamerica. A study on the Herpetofauna of Chihuahua, Mexico, with Ana Gatica, Univ. Autonoma de Cuidad Juarez, Chihuahua.

Biochemical Studies: Immunological analysis of the venoms and DNA analysis of red blood cells of three species of rattlesnakes. The majority of this research is being conducted at Indio Mountains Research Station and labs at UTEP.
