Continued Conservation of a Sonoran Desert Icon: the Desert Tortoise
Presenter: Taylor Edwards, Assistant Staff Scientist, University of Arizona Genetics Core
Dr. Edwards' recent genetic research on the southern lineage of desert tortoise has resulted in identification of a new species. In light of this discovery, Taylor and his team, together with colleagues from Canada and Mexico, have taken immediate, tangible steps to put a program in place to preserve the species in its natural habitat in Sonora, Mexico.

Hydrogeology of the Quitobaquito and Gran Desierto Wetlands: Insights from Environmental Isotopes and Water Chemistry
Presenter: Hector A. Zamora, PhD student, Department of Geosciences
This project is a cross-border, multi-institution collaboration, and seeks to establish the sources and recharge dynamics of these desert wetlands through a regional sampling regime, and environmental isotope analysis. Our results will provide the science needed to manage the biological and cultural wetland resources of Organ Pipe Cactus National Monument, and the El Pinacate and Gran Desierto de Altar Biosphere Reserve.
