A quantitative analysis of microbial community structure-function relationships in plant litter decay

A conserved interdomain microbial network underpins cadaver decomposition despite environmental variables

“…However, the overall composition of microbial decomposer communities did vary between different climates and locations, indicating that some functional redundancy also probably exists. In a study of agricultural crop organic matter decomposition (straw and nutrient amendments), researchers similarly demonstrated that although functional redundancy probably plays a role, key microbial taxa emerge as important plant decomposers 15 , and a meta-analysis of microbial community structure–function relationships in plant litter decay found that community composition had a large effect on mass loss 58 . In terms of climatic controls over cadaver decomposition, temperate locations had a more measurable microbial response (for example, phylogenetic turnover, potential cross-feeding) in soils than the arid location in our study, and plant studies support the idea that climate is a strong determinant of decomposition rates and microbial activity 59 .…”

Impact of CeO2 nanoparticles on the microbiota of the S. flos-cuculi L. (Caryophyllaceae) rhizosphere

“…48,49 Soil microbial communities are the poorly ununderstood driver of many processes that directly or indirectly govern the fluxes of carbon, nitrogen, and other elements through ecosystems. 47,50–52 In particular, rhizospheric microbiota and the symbiotic processes triggered by plant growth-promoting rhizobacteria (PGPR) play a fundamental role in improving productivity by reducing fertilization and pesticide utilization. 53 In this regard, nCeO 2 can impact this mutualistic relationship in different ways, both directly and indirectly.…”

Assessing the win–win situation of forage production and soil organic carbon through a short-term active restoration strategy in alpine grasslands

“…The activities of soil microorganisms and nutrient cycling at the ecological interface between vegetation and soil are further promoted, thereby increasing SOC ( Pang et al., 2020 ). Restoration measures such as grazing, reseeding, and fertilization affect soil microorganisms in the short term, which indirectly affects the decomposition of litter in soil and its corresponding nutrient contents ( Bilotta et al., 2007 ; Drewry et al., 2008 ; Waring et al., 2022 ; Su et al., 2023 ). As a result, soil nutrients at the sites were higher under a relatively heavy grazing intensity.…”
