A grant has been awarded to Drs. Morris, McConnaughay, Gehring and Frase at Bradley University to acquire instrumentation needed to support integrated studies of C and N dynamics including controlled environment growth chambers, photosynthesis and soil respiration equipment and a nutrient auto-analyzer. The equipment requested will be used within the department for individual projects, interdepartmental collaborative projects and integrated research-training of undergraduate and graduate students.The instrumentation will support on-going collaborative research efforts to examine the effects of altered C and N dynamics on native and invasive plants in restored prairie ecosystems. Specific projects will examine plant growth characteristics in the field and in the laboratory under controlled environmental conditions in chambers subjected to elevated CO2 and N deposition. Soil nutrient dynamics, including C and N turnover, will be evaluated using laboratory mineralization rates in tandem with measurements of plant growth characteristics. In addition to answering fundamental questions about restoration ecology and ecosystem change following disturbance, the instrumentation will be used as a tool by individual researchers to introduce undergraduates in their respective laboratories to integrated large-scale projects.

布拉德利大学的Morris、McConnauhay、Gehring和Frase博士获得了一笔赠款，用于购买支持碳和氮动态综合研究所需的仪器，包括受控环境生长室、光合作用和土壤呼吸设备以及养分自动分析仪。所要求的设备将用于系内的个人项目、部门间合作项目以及本科生和研究生的综合研究培训。该仪器将支持正在进行的合作研究工作，以检查C和N动态变化对恢复的草原生态系统中本地和入侵植物的影响。具体项目将在二氧化碳和氮沉积增加的室内受控环境条件下，研究田间和实验室中植物的生长特征。土壤养分动态，包括C和N周转，将使用实验室矿化速率与植物生长特征的测量相结合来评估。除了回答有关干扰后恢复生态学和生态系统变化的基本问题外，该仪器还将被个别研究人员用作工具，向各自实验室的本科生介绍综合大型项目。
