摘要: Abstract We examined taxonomic composition of fungal communities in Picea abies log bark using next generation sequencing. Three successional stages along gradients attributes were identified. In the initial stage, composed by yeasts, plant pathogens and cosmopolitan saprotrophic fungi with broad substrate utilization. intermediate was colonized mainly saprotrophs common decaying wood, symbionts epixylic plants nematode-trapping fungi. The final stage characterized dominance mycorrhizal Wood-decaying occurred all stages. However, their sporadic appearance samples suggests that they are not essential for decomposition. Our results provide an insight into hidden diversity wood-inhabiting – communities, associated decomposition as a component coarse woody debris.
