Tumamoc Hill Science Café

Series Title: The Tumamoc Hill Science Café

The Science Café at Tumamoc Hill provides speakers on topics that relate to the science, history, archeology, and educational mission of Tumamoc Hill, located to the west of “A” Mountain, near downtown. 
The talks are held in the library of the old Desert Laboratory, the buildings that are roughly half-way up the Hill. The staff asks that you make a reservation for the Science Café so they can have sufficient shuttle service for the participants. 
Please contact Cynthia Anson at cynthiaanson@email.arizona.edu or 520-629-9455 to reserve a seat.

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.
