Canopy gaps can result in abiotic heterogeneities and diverse niches from gap borders to centers, potentially affecting fine root decompositions mediated by soil fungal communities. Despite extensive discussions on the relationship between fungi decomposition, mechanism which locations regulate decomposition through community remains elusive. Here, we conducted an situ field experiment of Chinese Toon (Toona sinensis) roots a low-efficiency weeping cypress (Cupressus funebris) plantation forest across three microhabitats: borders, closed canopy areas. Soil communities were determined using internal transcribed spacer (ITS) sequencing after two years incubation. Results showed that properties nutrient content residual varied microhabitats, with exhibiting highest rates. While α-diversity remained relatively consistent, taxonomic compositions differed significantly. Decomposition rates did not show significant correlations properties, observed ASVs, or overall composition. However, they positively correlated relative abundance saprotrophic Sordariomycetes, turn total nitrogen (with correlation), peaking at borders. Overall variations primarily driven temperature magnesium roots. Further analysis revealed high similarities low dispersal limitations areas, more phylogenetically clustered These results demonstrate possess rate, likely due centralization functions such as saprotrophs existing “microbial seed bank” migrating findings highlight key role fungi, especially stressing importance fungi-driven mechanisms cycling, also informing sustainable management practices.

Within this study, we evaluated the fine root (trees and understory vegetation combined) morphological traits, production (FRP), carbon (C) input with litter in forest stands (dominated by either coniferous or deciduous trees) clearcut areas (previously dominated nutrient-rich organic soils. The study was conducted 26 sites hemiboreal land Latvia summarizes results obtained a two-year (2020–2022) using ingrowth method. Traits of roots varied significantly depending on development stage (stand area), dominant tree species type (coniferous deciduous), soil drainage status (drained naturally wet). According to second year, mean FRP among groups from 0.58 ± 0.13 1.38 0.28 t ha−1 yr−1, while C ranged 0.06 0.68 0.14 yr−1. More than half (59 4%) total occurred upper 0–20 cm layer. tended correlate positively C/N ratio negatively pH nutrient concentration. Incubating cores for at least two years is strongly recommended accurately estimate annual input. This helps avoid potential underestimation that may occur when only one incubation year (12 months after core installation). provided new insights into dynamics traits will help improve accuracy flow estimation forests soils Latvia.
