e0“This study compared Sphagnum decomposition in a Sphagnum palustre L.-dominated peatland and an R. auriculatum (Sapling)–S. palustre peatland by examining the microscopic structure of S. palustre and microbial community composition. Decomposition was higher in the R. auriculatum–S. palustre peatland”

Other claims from this paper (8)
- Association Bacterial metabolic types such as aerobic chemoheterotrophy and chemoheterotrophy had higher relative abundances in the R. auriculatum peatland.
- Association Fungal trophic modes, including combined ectomycorrhizal, ericoid mycorrhizal and saprotrophic functions, also had higher relative abundances in the R. auriculatum peatland.
- Observation Acid phosphatase and laccase differed significantly across decomposition stages.
- Observation Total nitrogen, C/N ratio and pH differed significantly across decomposition stages.
- Association Microbial communities are affected by physicochemical factors and enzyme activities in Sphagnum peat.
- Observation Phenolics, cinnamic acids and tannins were more downregulated than upregulated, indicating loss of phenolic compounds.
- Intervention effect R. auriculatum fine root invasion accelerated S. palustre cell wall and hyaline cell decomposition.
- Mechanism R. auriculatum fine root invasion, through altered enzyme activities and physicochemical properties, is suggested to drive restructuring of bacterial and fungal trophic modes in Sphagnum peat.
