“…In the present study, the detected diversity of fungal taxa was high and comparable to similar studies on the phyllosphere and soil fungi [17,30,42]. Despite that, the rarefaction curves did not reach the asymptote, indicating that a higher richness of fungal taxa could be detected by deeper sequencing.…”

“…The results demonstrated that managed and unmanaged P. sylvestris stands support similar diversity and composition of fungal communities associated with living needles and soil under the north temperate forest zone conditions (Figures 2-4). In support, Parlade et al [42] have shown that, in P. sylvestris stands, a different intensity of forest management has little effect on the overall diversity of soil fungi. The diversity and composition of fungal communities may also depend on the forest structure, i.e., the age and composition of the tree species [23,26], which together with other factors may determine the habitat heterogeneity [4].…”

The aim was to assess fungal communities associated with living needles and soil of Pinus sylvestris in managed and unmanaged forest stands to get a better understanding of whether and how different intensities of forest management affects fungal diversity and community composition under the north temperate forest zone conditions. The study was carried out in three national parks in Lithuania. Each included five study sites in managed stands and five in unmanaged stands. At each site, three random soil cores and five random last-year needle samples were collected. Following DNA isolation, a DNA fragment of the ITS2 rRNA gene region of each sample was individually amplified and subjected to high-throughput sequencing. Analysis of 195,808 high-quality reads showed the presence of 1909 fungal taxa. Richness and composition of fungal taxa were similar in each substrate (needles and soil) in managed vs. unmanaged sites. The most common fungi in needles were Coleosporium campanulae (12.4% of all fungal sequences), Unidentified sp. 3980_1 (12.4%), Unidentified sp. 3980_4 (4.1%) and Sydowia polyspora (3.1%). In soil: Unidentified sp. 3980_21 (8.6%), Umbelopsis nana (8.2%), Archaeorhizomyces sp. 3980_5 (8.1%) and Penicillium spinulosum (6.3%). The results demonstrated that managed and unmanaged P. sylvestris stands support similar diversity and composition of fungal communities associated with living needles and soil.

“…In selectively harvested plots, the decline in overall fungal richness was related to decrease in EcM fungi and yeasts. Our results are thus partly consistent with a study in Northern Sweden that found 30-40% decline in EcM fungal diversity in a few years after partial harvesting (Sterkenburg et al, 2019) but in a disagreement with studies in Spanish Mediterranean forests revealing no effect (Castano et al, 2018a;Parlade et al, 2019). However, our study corroborates the long-term selective harvesting effect on composition of fungi and specifically EcM fungi in Mediterranean forests, which was not evident in Sweden.…”

“…Decapitation of the spruce seedling associated with termination of photosynthetic assimilates and other organic compound transport to root and adjacent soil resulted in a gradual decrease in relative abundance of EcMF. Although this observation corresponds to previously reported changes in fungal communities after disruption of belowground C transport induced by tree girdling ( Högberg et al, 2001 ; Kaiser et al, 2010 ), clearcutting ( Kohout et al, 2018 ; Parladé et al, 2019 ), defoliation ( Parker et al, 2017 ), or bark beetle outbreaks ( Štursová et al, 2014 ; Pec et al, 2017 ), we can identify some interesting differences among the studies. Previously, Štursová et al (2014) documented the decrease in relative abundance of EcMF in the soils of spruce forests from 41% to less than 10% during 1 year after the dieback of all mature trees following a bark beetle outbreak.…”

Forest Microhabitat Affects Succession of Fungal Communities on Decomposing Fine Tree Roots

et al. 2021

Belowground litter derived from tree roots has been shown as a principal source of soil organic matter in coniferous forests. Fate of tree root necromass depends on fungal communities developing on the decaying roots. Local environmental conditions which affect composition of tree root mycobiome may also influence fungal communities developing on decaying tree roots. Here, we assessed fungal communities associated with decaying roots of Picea abies decomposing in three microhabitats: soil with no vegetation, soil with ericoid shrubs cover, and P. abies deadwood, for a 2-year period. Forest microhabitat showed stronger effect on structuring fungal communities associated with decaying roots compared to living roots. Some ericoid mycorrhizal fungi showed higher relative abundance on decaying roots in soils under ericoid shrub cover, while saprotrophic fungi had higher relative abundance in roots decomposing inside deadwood. Regardless of the studied microhabitat, we observed decline of ectomycorrhizal fungi and increase of endophytic fungi during root decomposition. Interestingly, we found substantially more fungal taxa with unknown ecology in late stages of root decomposition, indicating that highly decomposed roots may represent so far overlooked niche for soil fungi. Our study shows the importance of microhabitats on the fate of the decomposing spruce roots.
