The University of Wyoming Department of Renewable Resources is soliciting applications for 
a full-time postdoctoral research scientist to conduct research on the physiological ecology 
and isotope systematics of columnar cacti. The research scientist will lead field and 
glasshouse studies on photosynthesis, water relations and isotopic fractionation patterns in 
saguaro cactus (Carnegiea gigantea). The scientist will have access to the University of 
Wyoming Stable Isotope Facility (uwacadweb.uwyo.edu/sif/) and opportunities to 
collaborate with a diverse group of researchers at UW and the University of Arizona in 
Tucson. A Ph.D. at the time of appointment in ecology, plant physiology or a closely related 
field is required. Familiarity with stable isotope approaches and photosynthetic gas 
exchange measurements is desired. The position will be available February 1, 2008 and will 
offer a generous salary and benefits. Applications will be reviewed beginning December 15, 
2007 and until the position is filled. To apply, please send a current CV, contact information
