9727795 Dighton Mycorrhizal fungi are able to form a biological bridge between two resource patches. Nutrients and carbon can then be translocated between patches by the fungi. This SGER research will use new technology, Fourier Transform Infrared Radiometry (FTIR) to (1) determine the cascade of decomposition products in response to fungal enzymes on resource islands with or without fungal bridges, and (2) assess if decomposition products from different plant materials can be determined qualitatively with this technique. This research has direct application for linking microbial diversity in the soil with ecosystem function through the process of decomposition. This will be the first attempt to use FTIR technology to link structure and function in soil microbial ecology.

9727795个Dighton菌根真菌能够在两个资源块之间形成生物桥梁。然后，营养物质和碳可以通过真菌在斑块之间转移。这项SGER研究将使用新技术傅里叶变换红外辐射(FTIR)来(1)确定有或没有真菌桥的资源岛上真菌酶响应的级联分解产物，以及(2)评估是否可以用该技术定性地测定来自不同植物材料的分解产物。本研究对于通过分解过程将土壤微生物多样性与生态系统功能联系起来具有直接的应用价值。这将是首次尝试利用FTIR技术将土壤微生物生态中的结构和功能联系起来。
