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

本项目将在雪松溪生态系统科学保护区使用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（包括物种内的基因型，具有不同功能的物种和来自不同进化谱系的物种）。该研究将通过遥感植物的反射光光谱，从天空和太空测量生物多样性，并研究生物多样性对生态系统和全球过程的影响。来自四个机构的项目科学家将研究植物生物多样性、土壤微生物多样性和生态系统功能之间的联系。这些努力将有助于发展可定期监测生物多样性的机载和卫星平台，并为替代概念提供关键的实验证据，即生物多样性的一个指标可用于提供有关其他指标的信息。该项目将改变检测全球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）方面的培训机会。研究结果将整合到雪松溪校园生态项目和美国宇航局资助的STEM教育中心，以培训美国原住民保留地教师。公民科学家将通过MN物候学网络参与进来。数据和研究成果将存档在可公开访问的数据存储库中。

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.
