The Ecology and Evolution graduate group in the Department of Biology at the University of Pennsylvania invites applications from students interested in pursuing a Ph.D. in association with a 5-year grant on global climate change from the NSF Program in International Research and Education (PIRE). This project, now in its second year, addresses the combined ecological consequences of climate change and grazing pressures by nomadic pastoralism in northern Mongolia, a region of the world expected to experience some of the largest temperature increases in the coming years. The project is a collaboration among researchers at Penn, the Academy of Natural Sciences of Philadelphia, the National University of Mongolia and the Mongolian Academy of Sciences. Graduate students associated with the project will receive support through a combination of PIRE fellowship and teaching assistantship funds, and will conduct field-based Ph.D. research in Mongolia with Penn faculty and members of the collaborating institutions.
