GRADUATE RESEARCH ASSISTANTSHIP A graduate research assistantship is available for students interested in pursuing a Ph.D. in ecology. The successful applicant will work on a multi-investigator, NSF-funded project that examines the effects of elevated carbon dioxide on ecosystem dynamics in the Mojave Desert. The field work for the project will be at the Nevada Desert FACE Facility (NDFF). The student will work in the lab of R.D. Evans at the University of Arkansas. The Arkansas research group will address the effects of elevated carbon dioxide on nitrogen fixation by biological soil crusts, soil nitrogen transformations, litter quality, and gaseous nitrogen loss. The RA will cover the student stipend and tuition, plus all travel and research expenses. Exceptional students may also qualify for an additional research stipend from the University. The University of Arkansas has a young group of active ecologists offering a variety of courses in ecology and evolutionary biology. Excellent opportunities exist at the Center for Advanced Spatial Technologies for students interested in GIS and remote sensing, and at the Stable Isotope Science Center of the Ozarks for students interested in stable isotope applications in ecology. Requirements: The student must be accepted into the graduate program in Biological Sciences at the University of Arkansas. The starting date is spring semester of 1999, although this can be delayed to summer for exceptional applicants. For more information contact Dr. R.
