The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers through a series of experiments. The expected outcome of this project is a clear understanding of the role of traits in wood decomposer communities, especially their influence on priority effects, competitive hierarchies, and the resultant wood decay rate.

该项目旨在了解对森林内碳返回大气的控制，特别是从微生物的角度关注这一问题。微生物动力学和木材腐烂对全球碳循环至关重要。该领域缺乏的是木材分解者的基于特征的生态学。该项目计划通过一系列实验研究真菌和卵菌内生菌与分解者之间的相互作用。这个项目的预期成果是一个清晰的理解木材分解社区的作用，特别是他们的影响，优先效应，竞争层次结构，以及由此产生的木材腐烂率的特点。
