RICHTER'S SOIL-ECOSYSTEM BIOGEOCHEMISTRY PROGRAM Professor Daniel deB. Richter's Soil Biogeochemistry Laboratory is recruiting a biogeochemist PhD student to enroll in the fall of 2009. The lab has research sites that are >50-year-old, a hydraulic Geoprobe that can sample to >20-m, analytical instrumentation, and a history of providing excellent mentoring for linking soils with ecosystem science. Although we focus on the belowground components of ecosystems, we are interested in all geographic scales of ecosystem ecology. On-going projects involve the changing model of soil, anthro-pedology, long-term soil-ecosystem experiments, and global soil change (http://calhoun.env.duke.edu; http://ltse.env.duke.edu). Questions can be directed to Dan Richter at [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> and applications are due 15 December. On-line applications are available at: http://www.gradschool.duke.edu/admissions/
