Collaborative Research: Dimensions NASA: Linking remotely sensed optical diversity to genetic, phylogenetic and functional diversity to predict ecosystem processes

该项目将使用雪松溪生态系统科学保护区的三种生物多样性操作来测试是否可以在多个空间尺度上远程检测植物多样性(包括物种内的基因类型、具有不同功能的物种和来自不同进化谱系的物种)。这项研究将通过遥感植物的反射光谱从天空和太空测量生物多样性，并调查生物多样性对生态系统和全球进程的影响。来自四个机构的项目科学家将调查植物生物多样性、土壤微生物多样性和生态系统功能之间的联系。这些努力将有助于开发能够定期监测生物多样性的机载和卫星平台，并为代孕概念提供关键的实验证据，即一种生物多样性度量可以用来提供其他度量的信息。该项目将改变检测世界各地生物多样性变化的方法，并将为年轻科学家提供大量科学、技术和数学(STEM)培训机会。结果将被整合到雪松溪校园生态计划和NASA资助的STEM教育中心，以培训美洲原住民保留地教师。公民科学家将通过MN物候学网络参与进来。数据和研究成果将保存在公众可访问的数据储存库中。

This project will use three biodiversity manipulations at the Cedar Creek Ecosystem Science Reserve to test whether plant diversity (including genotypes within species, species with different functions, and species from different evolutionary lineages) can be detected remotely at multiple spatial scales. The study will measure biodiversity from the sky and space by remotely sensing the reflected light spectra of plants and investigate the consequences of biodiversity for ecosystem and global processes. Project scientists from four institutions will investigate linkages between plant biodiversity, soil microbe diversity and ecosystem function. These efforts will serve in the development of airborne and satellite platforms that can routinely monitor biodiversity and provide critical experimental evidence for the concept of surrogacy, i.e., that one metric of biodiversity can be used to provide information about others.The project will transform methods for detecting changes in biodiversity worldwide and will provide numerous training opportunities in science, technology and math (STEM) for young scientists. Results will be integrated into the Cedar Creek Schoolyard Ecology program and a NASA-funded STEM Education Center to train Native American reservation teachers. Citizen scientists will be engaged through the MN Phenology Network. Data and research outcomes will be archived in publically accessible data repositories.
