Gloria Jimenez

My major project will use modern and fossil corals from
the Galapagos to study how the El Nino Southern Oscillation has changed over
time and affects the climate of the Americas and the world. I also, however,
want to include a significant policy aspect: linking science to outreach and
management in a meaningful way. 

Paul Szejner

I am currently working as a graduate research assistant
at the Tree Ring Laboratory at The University of Arizona. My research
interest relies on the feedbacks between vegetation and climate. I have been
developing early and late wood tree ring chronologies in order to understand
intra annual processes in the North American Monsoon region. By analysing the
carbon and oxygen stable isotopes from tree ring cellulose from several sites
in Arizona, Utah, New Mexico and Colorado, we will contribute on the

Aaron M. Lien

My research focuses on the use of ecosystem services in
large landscape conservation. I will be investigating the use of a payment
for ecosystem services program to support jaguar habitat in Southern Arizona.
I'm also interested in how climate change models and ecosystem services can
be integrated into conservation prioritization for large landscapes. 

America N. Lutz Ley

America is a Graduate Research Associate with the Udall Center for Studies in Public Policy, and a Ph.D. student in Arid Lands Resource Sciences at the University of Arizona. She has a Master degree in Social Sciences, with major in Public Affairs from El Colegio de Sonora, and a Bachelor degree in Psychology, with major in Educational Psychology from the Universidad de Sonora, both from her country, Mexico.

Kevin E. Bonine

Kevin's past reserach involved work on evolutionary physiology in lizards. Currently he is studying canyon treefrog (Hyla arenicolor) phylogeography, life history, and disease ecology. Other projects include field research on gila monsters (Heloderma suspectum), otoacoustic emissions in vertebrate ears, rattlesnake ecology, etc. His has also been involved in several local inventory and monitoring programs that shed light on changes in local abundance and distribution.

David J.P. Moore

David Moore is a broadly trained plant ecologist and ecosystem scientist. His research centers on the changing role of forests in the carbon cycle and the controls of carbon use and allocation in plants and ecosystems. His research uses a broad range of observation types from ground measurements to satellite remote sensing and focuses of time series of ecosystem processes and the timings of transitions between ecosystem states both seasonally and interannually.
