Brown rots are typically involved in the earliest phase of lignocellulose breakdown, which therefore influences colonization by other microorganisms. However, few studies have focused on the impact of introducing decayed wood into forest environments to gauge successional colonization by natural bacterial and fungal communities following partial decay. This study aimed to address this issue by investigating the bacterial and fungal colonization of Norway spruce (Picea abies) wood, after intermediate and advanced laboratory-based, pre-decay, by the brown rot fungus Gloeophyllum trabeum. Using Illumina metabarcoding, the in situ colonization of the wood blocks was monitored 70 days after the blocks were placed on the forest floor and covered with litter. We observed significant changes in the bacterial and fungal communities associated with the pre-decayed stage. Further, the wood substrate condition acted as a gatekeeper by reducing richness for both microbial communities and diversity of fungal communities.

For this purpose, seven isolates from different provenances of M. coryli were studied under controlled laboratory conditions with the goal of laying the foundations of a mathematical model describing key aspects of the pathogen's life cycle.

The dataset was subsequently analyzed estimating the parameters of non-linearfunctions which consider the relationship between the mycelium growth rate and the germination of the spores with environmental temperature.

Using 50 decomposer fungal species, spanning a range of peak decay stages, we measured (1) the activity of four polysaccharidases and two oxidases generated by each species, and (2) fungal species’ growth rates. We found that the activity of cellobiohydrolase and growth rate were negatively correlated with peak time point for filamentous fungi; fungi peaking early had greatest cellobiohydrolase activity and fastest growth.
