Microbes mediate many important ecosystem services yet remain relatively poorly understood. This research examines how microbes - the bacteria and fungi that occur in soils - contribute to the ability of grassland ecosystems to respond to climate change. Desert grassland soils harbor high microbial diversity, but collecting, identifying and interpreting this diversity remains a challenge. Genomic tools will be used to identify the microbes in grassland soils under different environmental conditions. This information on microbial community composition will be linked with previous measures of microbial function in order to predict how microbes and their associated plant communities will respond to climate change. Grasslands provide many ecosystem services that benefit humans, yet they are changing rapidly in response to climate change and human land use. Results from this study will be communicated to the public in collaboration with the Sevilleta National Wildlife Refuge in central New Mexico. Educational materials and exhibits for the Refuge's new Visitors' Center will be developed based on this project. In addition, the researchers will participate in the Junior Scientist Outreach Program, a new outreach activity coordinated by the University of New Mexico Department of Biology. This activity targets 4th and 5th grade students from under-represented groups and engages then in hands-on activities coordinated by the research scientists.

微生物介导了许多重要的生态系统服务，但知识仍然相对较差。这项研究研究了微生物（土壤中发生的细菌和真菌）如何有助于草地生态系统应对气候变化的能力。沙漠草原土壤具有高度微生物的多样性，但是收集，识别和解释这种多样性仍然是一个挑战。基因组工具将用于在不同的环境条件下鉴定草地土壤中的微生物。有关微生物群落组成的此信息将与以前的微生物功能的度量有关，以预测微生物及其相关植物群落如何应对气候变化。草原提供许多使人类受益的生态系统服务，但它们正在响应气候变化和人类土地使用而迅速变化。这项研究的结果将与新墨西哥州中部的塞维利塔国家野生动物保护区合作传达给公众。 避难所新游客中心的教育材料和展览将根据该项目开发。此外，研究人员将参加由新墨西哥大学生物学系协调的新的外展活动初级科学家外展计划。该活动针对来自代表性不足的群体的4年级和5年级学生，然后从事研究科学家协调的动手活动。
