Factors that control decomposition and associated nutrient                 dynamics in phosphorus-limited wetland ecosystems will be                       studied.  The effects of litter quality and environmental factors               on decomposition will be determined with laboratory and field                   experiments.  Litter quality variables will include nutrient and                lignin content.  Environmental variables will include inorganic P               availablity and redox potential.  Standard methods will be used                 to measure decay rates and nutrient dynamics.                                        The proposed research is an appropriate dissertation topic.                Mr. Bridgham, under the guidance of Dr. Richardson, will                        certainly make contributions to our understanding of                            decomposition in wetland ecosystems.  The excellent research                    facilities at Duke University will provide all of the support                   needed to conduct the proposed research.
