9977494摘要生物体获取、利用和转化能量和物质的方式的研究是生物科学许多领域的核心，包括植物和动物生理学、生态学和地球化学。密西西比大学生物系将建造一个新的实验室，专门从事这种测量，即密西西比大学生物系统中能量和物质通量分析实验室。该实验室将配备仪器，用于检查从细胞到生态系统等各种复杂程度的生物系统之间的能量和物质通量。使用实验室中现有的仪器，将有可能对生物生产力和呼吸速率、能量和物质的同化效率以及生物组织层次结构中无机和有机物质的转化进行精确、实时和长期的测量。该实验室旨在成为密西西比大学和其他机构其他部门的研究人员和学生之间合作研究的催化剂。学生在研究方法的培训将通过个别教师监督的本科生和研究生研究项目，并通过建立实验室课程，包括植物学，生态学，微生物学，湖沼学和生理学完成。新实验室将包括的仪器包括：（1）一台Carlo Erba碳氢氮硫分析仪，（2）一台Shimadzu总有机碳分析仪，（3）两台Hewlett-Packard气相色谱仪，（4）一台Li-Cor光合系统，（5）一台Parr 1266氧弹量热计，以及（6）一台Technicon连续流动自动分析仪。UM生物系统中能量和材料通量分析实验室将为生物介导的能量和材料转化研究提供一个独特的中心，有助于吸引各种背景的人才从事生物科学职业。

9977494AbstractExamination of the ways organisms acquire, utilize, and transform energy and materials is at the core of many fields in the biological sciences including plant and animal physiology, ecology, and biogeochemistry. A new laboratory is to be constructed in the University of Mississippi Department of Biology that will specialize in such measurements, the University of Mississippi Laboratory for Analysis of Energy and Materials Flux in Biological Systems. The laboratory will be equipped with instrumentation for examination of fluxes of energy and materials through and between biological systems at levels of complexity ranging from cells to ecosystems. Precise, real-time, and long-term measurements of rates of biological productivity and respiration, assimilation efficiencies of enery and materials, and transformations of inorganic and organic materials across a heirarchy of biological organization will be possible using the instrumentationavailable in the laboratory. The laboratory is intended to be a catalyst for collaborative studies between researchers and students in other departments at the University of Mississippi, and at other institutions. Training of students in research methodologies will be accomplished through individual faculty-supervised undergraduate and graduate research projects, and through established laboratory courses including botany, ecology, microbiology, limnology, and physiology. Instruments to be included in the new laboratory include, (1) a Carlo Erba carbon-hydrogen-nitrogen-sulfur analyzer, (2) a Shimadzu total organic carbon analyzer, (3) two Hewlett-Packard gas chromatographs, (4) a Li-Cor Photosynthesis System, (5) a Parr 1266 oxygen bomb calorimeter, and (6)a Technicon continuous-flow autoanalyzer. The UM Laboratory for Analysis of Energy and Materials Flux in Biological Systems will provide a unique center for studies of biologically-mediated energy and materials transformations, helping to attract talented individuals of all backgrounds to careers in biological science.
