“…More importantly, microorganisms are quite sensitive to the chemical characteristics of litter. Thus, even in the same soil environment, microorganisms in different litters will form distinct communities in the short term (Bani et al, 2018;Buresova et al, 2021). In the present study, we found that the relative abundances of Actinomycota, Streptomyces, Promicromonospora, and Nonomuraea increased significantly in 20-43-year litter in the early stage of decomposition, whereas the relative abundances of Ascomycota, Aspergillus, and Chaetomium exhibited the same trend in the late stage of decomposition.…”

“…According to the structural equation modelling (Figure 6), vegetation restoration increased litter substrate quality (based on the loading First, decreases in litter lignin/N ratio with vegetation restoration increased the availability of litter substrates to decomposers, and simultaneous increases in N and P contents could support the growth of more microorganisms, accelerating the litter decomposition rate (Buresova et al, 2021;Xiao et al, 2019). In addition to the abovementioned main factors, the contents of phenols and condensed tannins in litter also decreased significantly with vegetation restoration.…”

The chemical traits of litter are among the most critical factors that affect its decomposition. During vegetation restoration of planted forests, increasing age of the planted species and succession of the understory species may lead to significant changes in litter traits. However, it is unclear how these changes occur and how they affect litter decomposition. Therefore, we studied the decomposition of litter from four Robinia pseudoacacia plantations in the Loess Plateau in China with stand ages of 10-43 years using an indoor simulation test. We measured changes in litter substrate quality and chemical diversity, structural properties of the litter microbial community, activity of litter enzymes, and mixed decomposition effects during vegetation restoration. Their relationships to changes in litter decomposition rate were analyzed using structural equation modeling. Improvements in substrate quality of forest litter induced by vegetation restoration drove changes in fungal community composition during late decomposition (day 358), which in turn increased the activity of lignindecomposing enzymes and ultimately accelerated litter decomposition. At the same time, decreases in the chemical diversity of forest litter induced by vegetation restoration reduced the diversity of litter fungi during middle and late decomposition (days 182 and 358). This caused significant negative mixed decomposition effects, thereby inhibiting litter decomposition. However, improvements in litter substrate quality dominated the changes in litter decomposition rate, and the decomposition rate of R. pseudoacacia plantation litter thus increased over the course of vegetation restoration.
