The aim of this project is to provide undergraduates new experiences in applying state-of-the-art, computer-interfaced instruments to the study of whole organisms. It permits them to implement mebabolic studies at several levels in the Biology curriculum through the acquisition and utilization of two Ametek S- 3A/II oxygen analyzers, the upgrade of the Li-Cor CO2 analyzer to the standard of Li-Cor 6250, and acquisition of appropriate computer and interfacing equipment. The Ametek oxygen analyzers are being applied to laboratory exercises on metabolism in freshman Biology and in three upper division courses. Several of these laboratory exercises examine temperature effects on biological processes. Both instruments and the computer-interfacing capabilities also enrich independent study and research participation programs which are viewed as essential for a strong department. The project is significant because it enhances quantitative and experimental experiences at the organismic level in this department, at a time when improvements recently have been made in instrumentation and methodology for ecological studies and for cellular and biotechnological studies. Students at several levels of educational development now have access to quality systems for studies of organismic gas exchange in highly experimental settings in which instruments are computer controlled and data are reduced and analyzed on-line. The grantee institution is matching the NSF award with an equal sum obtained from non-Federal sources.

这个项目的目的是为本科生提供新的经验，应用最先进的，计算机接口的仪器来研究整个生物体。它允许他们通过购买和使用两台阿美泰克S-3A/II氧气分析仪，将Li-COR二氧化碳分析仪升级到Li-COR6250标准，以及购买适当的计算机和接口设备，在生物课程的多个层面上实施代谢研究。Ametek氧分析仪正被应用于一年级生物学和三门高年级课程的新陈代谢实验室练习。这些实验室练习中有几项考察了温度对生物过程的影响。这两种仪器和计算机接口能力也丰富了独立的学习和研究参与方案，这被视为一个强大的系所必需的。该项目意义重大，因为它加强了该部门在有机体层面上的定量和实验经验，而最近在生态学研究以及细胞和生物技术研究的仪器和方法方面取得了改进。现在，处于几个教育发展水平的学生可以在高度实验性的环境中使用高质量的系统来研究有机体气体交换，在这种环境中，仪器由计算机控制，数据被减少并在线分析。接受资助的机构正在将NSF的奖励与从非联邦来源获得的同等金额相匹配。
