Many plants are dependent on belowground fungi to help them obtain nutrients and respond to environmental stress. Revealing the patterns and drivers of these interactions is important for understanding forest ecology and improving management practices. Plant-fungal associations in the soil can dramatically influence plant growth and terrestrial ecosystem function. This research will take the advantage of several existing datasets, including those collected by National Ecological Observatory Network (NEON) and the U.S. Forest Service (USFS), to understand: 1) nation-wide patterns of plant-fungal associations; 2) key factors that influence these associations; and 3) how plant-fungal interactions influence key ecosystem functions such as carbon cycling. This research project will contribute to the fields of microbial ecology, ecosystem science, and global change biology by formulating and testing new theories about plant-fungal associations. Results of the project will inform forest managers, policymakers, and other stakeholders on how to improve ecosystem management of plant and fungal biodiversity to promote sustainable ecosystems. The project will contribute to the professional development of diverse students at several stages.The goal of this project is to understand the patterns, drivers, and consequences of the linkages between plant and mycorrhizal fungal diversity across spatial and temporal scales. This information will enable better predictive understanding of essential ecosystem functions which they control. The project will use a holistic, scale-dependent framework that forecasts the strength and direction of arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) fungal-plant associations, and provides greater insight about the consequences for ecosystem functioning across space and over time. Specific objectives of the project include: 1) elucidation of patterns of plant and mycorrhizal fungal diversity across scales by extensive DNA sequencing and analysis; 2) determination of key abiotic and biotic drivers of observed co-occurence patterns; and (3) forecasting the effects of plant-mycorrhizal fungal couplings on tree productivity and soil C storage, two key forest ecosystem functions. By linking multiple facets of both above- and belowground diversity in a scale-dependent context, the project will produce robust continental-wide distribution maps of AM and EM fungi for the first time. Leveraging data-rich sampling of putative biotic and abiotic drivers of plant and fungal diversity by NEON and the USFS, the project will also provide broad-scale understanding of when and where these drivers serve to couple or decouple plant and mycorrhizal fungal diversity. Finally, by linking plant and mycorrhizal fungal diversity to the consequences they have for plant productivity and soil C storage and stability, the project will improve understanding of ecosystem resilience to environmental stress. The project will train diverse undergraduate and graduate students, postdoctoral scholars, and will enhance the development of three early=career scientists.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

许多植物都取决于地下真菌，以帮助他们获得营养并应对环境压力。揭示这些相互作用的模式和驱动因素对于理解森林生态学和改善管理实践很重要。土壤中的植物 - 企业联想可以极大地影响植物生长和陆地生态系统功能。这项研究将利用几个现有的数据集，包括国家生态观测网络（NEON）和美国森林服务局（USFS）收集的数据集，以了解：1）全国范围内的植物 - 植物 - 真菌关联模式； 2）影响这些关联的关键因素； 3）植物企业的相互作用如何影响关键生态系统功能，例如碳循环。该研究项目将通过制定和测试有关植物 - 真菌关联的新理论，为微生物生态学，生态系统科学和全球变化生物学的领域做出贡献。该项目的结果将为森林经理，决策者和其他利益相关者提供有关如何改善植物和真菌生物多样性的生态系统管理以促进可持续生态系统的信息。该项目将在多个阶段为不同学生的专业发展做出贡献。该项目的目的是了解植物与植物和时间范围内植物与菌根真菌多样性之间联系的模式，驱动因素和后果。这些信息将使对他们控制的基本生态系统功能有更好的预测理解。该项目将使用一个整体，依赖规模的框架，以预测羊膜菌根（AM）和外生菌骨（EM）真菌植物植物关联的强度和方向，并为对整个空间和随着时间的推移的生态系统功能的影响提供了更大的见解。该项目的特定目标包括：1）通过广泛的DNA测序和分析阐明范围内植物和菌根真菌多样性的模式； 2）确定观察到的共存在模式的关键非生物和生物驱动因素； （3）预测植物 - 菌株真菌耦合对树木生产率和土壤C存储的影响，这是两个关键的森林生态系统功能。通过在规模依赖性的环境中链接上层和地下多样性的多个方面，该项目将首次产生AM和EM真菌的稳健范围的分布图。利用霓虹灯和USFS的植物和真菌多样性的假定生物和非生物驱动器的数据采样，该项目还将提供广泛的了解这些驱动因素何时以及何时将这些驱动因素用于将植物或分离植物和菌根真菌多样性。最后，通过将植物和菌根真菌的多样性与植物生产力和土壤C储存和稳定性的后果联系起来，该项目将提高对生态系统对环境压力的弹性的了解。该项目将培训多元化的本科生和研究生，博士后学者，并将增强三个早期=职业科学家的发展。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点评估来支持的，并具有更广泛的影响。
