真菌群落的组装历史对木本资源的分解、养分循环和生态系统功能具有重要作用。然而，它还没有明确确定是否真菌物种到达第一可能，潜在地，决定了随后的途径的社区发展，也就是说，是否有一个优先级的影响，在物种水平。我们使用传统的文化为基础的技术，再加上扩增的遗传标记的测序，以配置的真菌群落山毛榉（山毛榉）磁盘已分别与9个物种的真菌演替的不同阶段的预殖民。在社区组成的明显差异是明显的，由不同的物种与三个不同的继任者社区确定的预殖民化，表明个别物种可能有关键的影响，在驾驶组装历史。优先效应可能与生物化学改变的资源和战斗能力的前身。
Assembly history of fungal communities has a crucial role in the decomposition of woody resources, and hence nutrient cycling and ecosystem function. However, it has not been clearly determined whether the fungal species that arrive first may, potentially, dictate the subsequent pathway of community development, that is, whether there is a priority effect at the species level. We used traditional culture-based techniques coupled with sequencing of amplified genetic markers to profile the fungal communities in beech (Fagus sylvatica) disks that had been pre-colonised separately with nine species from various stages of fungal succession. Clear differences in community composition were evident following pre-colonisation by different species with three distinct successor communities identified, indicating that individual species may have pivotal effects in driving assembly history. Priority effects may be linked to biochemical alteration of the resource and combative ability of the predecessor.
