Nate is currently working on his Master's Thesis at San Diego State University. His research is on the polytypic Western Whiptail, Aspidoscelis tigris, which exhibits extensive morphological variation and is widely distributed throughout all the major desert regions of North America.

Anny Peralta-García

Anny recently finished her undergraduate research at the Universidad Autónoma de Baja California, in Ensenada and currently works for the conservation organization GECI. Her research is on the Garden Slender Salamander (Batrachoseps major), which ranges from Los Angeles, in the United States to El Rosario, in Baja California, México. The species of the genus are cryptic, lacking morphological characters to distinguish them. The use of molecular markers has discovered new lineages, and has shown Batrachoseps as a very diverse clade in North America.

Jorge is currently completing his undergraduate research at the Universidad Autónoma de Baja California, in Ensenada and is one of the primary collections managers for their research collection. His research is on the thermoregulation of the Southern Sagebrush Lizard (Sceloporus vandenburginaus) in the Sierra San Pedro Mártir and its preferred microhabitat. With the use of miniature computers, Jorge has recorded operative temperatures by using biophysical models, which are compared against actual lizard temperatures.
