Quantification of different processes affecting the assembly ecological communities remains challenging, especially in species-rich communities. While role environmental filtering has generally been well established, fewer studies have experimentally shown how other processes, such as biotic filtering, structure Here, we studied relative roles and colonization wood-inhabiting fungi, a species-rich, highly interactive, environment-sensitive group species. We conducted field experiment where simulated with inoculations nine fungal species habitat patches (i.e., logs) varying abiotic conditions. characterized local resident before success inoculated after one two years using DNA metabarcoding. asked what determined by comparing predictive performance alternative models. These models included either only predictors physical log properties) or additionally aspects richness, community composition, amount) predictors. all successfully colonized logs, rate factors explaining their varied among The four was explained mostly variables, while three influential from presence individual to collective multiple Finally, for species, showed poor performance. Our results indicate may jointly Overall, show that vary idiosyncratically response factors, highlighting need consider complexity species-level responses when predicting community-level changes.

Abstract Many species of wood-inhabiting fungi, particularly in the boreal forests Nordic countries, face significant extinction risks. The historical impact commercial forestry has led to fragmented old-growth forests, meaning that lost from these areas may not naturally return newly protected habitats. This study investigates potential inoculation as a management tool aid reintroduction threatened fungal species. Specifically, we tested whether red-listed associated with dead pine wood could successfully establish inoculated logs and identified factors influencing success. We cultured mycelium five target ( Anthoporia albobrunnea, Antrodia crassa, infirma, Crustoderma corneum, Dichomitus squalens ) selected monitoring log characteristics conducting DNA analysis community before after inoculation. Our findings demonstrate all established at least some (28–60% success), variable effects on abundance. Additionally, presence certain fungi correlated success These results suggest can be promising method for aiding recovery appropriate forest Long-term is necessary assess fruiting population sustainability, while further exploration alternative techniques enhance effectiveness efforts practices.
