Quantitative Teaching of Abiotic-Biotic Interactions in Aquatic and Terrestrial Ecosystems

该奖项为凯洛格生物站提供资金， 密歇根州立大学购买四项：两个基本气体 色谱法、扫描分光光度计和pH计。 目前，凯洛格生物站暑期教学计划 提供了生态学的本科课程， 强调在小组环境中的实践经验。 一些课程讨论了生态系统的两个方面 过程和种群生态学。 有了这些新设备 他们将从教学课程中消除 将生态学的概念分为基于生态系统和基于人口的概念， 相反，将沿着地球化学的路线和 营养相互作用 为了加强这一新的教学重点，他们 我希望为这些人建立一个更量化的框架， 实地/实验室演习，说明 陆生和水生模式的非生物和生物成分 系统. 这些工具将被学生用来量化 有机物的无机和有机前体和产物 活动，初级生产者的颜料，以及其他重要的 群落的非生物和生物方面。 现场/实验室 通过这种仪器进行的演习将提供 学生一个实际的“感觉”的概念融合两个 生态学的重要领域。 受助机构正在匹配 这个NSF奖的资金来自非联邦来源。

This award provides funds to The Kellogg Biological Station at Michigan State University to purchase four items: two basic gas chromatographies, a scanning spectrophotometer, and a pH meter. Currently, The Kellogg Biological Station summer teaching program offers a diversity of undergraduate courses in ecology which emphasize hands-on, field experience in a small group setting. Several of the courses discuss aspects both of ecosystem processes and of population ecology. With this new equipment they will eliminate from the teaching curriculum the separation of ecology into ecosystem-based and population-based concepts and instead, integrate both along the lines of biogeochemistry and trophic interactions. To enhance this new teaching focus, they wish to create a more quantitative framework for those field/laboratory exercises which illustrate interactions between abiotic and biotic components of terrestrial and aquatic model systems. These instruments will be used by students to quantify inorganic and organic precursors and products of organism activities, pigments of primary producers, and other important abiotic and biotic aspects of communities. The field/laboratory exercises made possible by this instrumentation will provide students a practical "feel" for the conceptual integration of two important areas in ecology. The grantee institution is matching this NSF award with funds from non-Federal sources.
