MRI: Acquistition of an Integrated Gas Exchange and Fluorescence Instrument for Multidisciplinary Physiological Research

格林内尔学院获得了一项奖项，以支持生物学研究和教育，并为生理学的多样化研究提供主要研究仪器。 LI-6400XT 仪器将对教师及其高年级本科生的积极研究产生直接影响，并很好地帮助生物学学生通过研究来学习，这是最有效的科学教育方式。格林内尔学院坚定地致力于为所有学生提供优质的科学教育和研究培训，包括那些传统上在科学领域代表性不足的学生。该仪器将支持格林内尔的承诺，从国家认可的格林内尔科学项目的新生实验室经验开始，贯穿我们生物学课程的各个级别。该研究仪器将丰富学生的学习，促进真实的研究体验，从而产生高质量的成果。LI-6400XT 代表了可用于实时分析光合作用（即二氧化碳吸收）和呼吸（即二氧化碳输出）的最先进技术，将立即用于植物生理学、植物生态学、真菌生物学和生物地球化学的研究项目。该仪器便携、灵活，并且可以控制光、温度和湿度，可以在各种生命系统和环境中进行测量，从原核生物和真菌到植物、动物和土壤；从实验室到偏远的现场。 LI-6400XT 的多种功能将为研究有关控制因素的重大问题提供新的方法：(1) 植物对温度胁迫的适应； (2)植物对干旱的适应； (3)旱地原核生物和真菌的分解； (4) 河流漫滩中的碳循环如何运作。

An award is made to Grinnell College to support biology research and education with a major research instrument for diverse studies of physiology. The instrument, the LI-6400XT, will have an immediate impact on active research by faculty and their advanced undergraduate students, and it well help biology students in several courses learn by research, the most effective kind of science education. Grinnell College has a deep commitment to providing quality science education and research training to all students, including those traditionally underrepresented in the sciences. This instrument will support Grinnell's commitment, beginning with the incoming-student lab experiences of the nationally recognized Grinnell Science Project, and weaving through every level of our biology curriculum. This research instrument will enrich student learning, facilitating authentic research experiences that generate high-quality outcomes.Representing the foremost technology available for real-time analysis of photosynthesis (i.e., carbon dioxide uptake) and respiration (i.e., carbon dioxide output), the LI-6400XT will find immediate use in research projects in plant physiology, plant ecology, fungal biology, and biogeochemistry. Portable, flexible, and allowing control of light, temperature, and humidity, the instrument enables measurements in a wide range of living systems and settings, from prokaryotes and fungi, to plants, animals, and soils; and from laboratories to remote field sites. The multiple functions of the LI-6400XT will provide new means to investigate significant questions about what controls: (1) plant acclimation to temperature stress; (2) plant adaptation to drought; (3) decomposition by prokaryotes and fungi in drylands; and (4) how the carbon cycle operates in river floodplains.
