Soil community richness and composition jointly influence the multifunctionality of soil along the forest-steppe ecotone

Xiao-Fang Du et al.

Summary: Soil biodiversity, including richness and community composition of soil organisms, plays a crucial role in soil multifunctionality. The composition of soil communities has a greater impact on soil multifunctionality at the regional scale, while the richness of soil organisms indirectly influences soil multifunctionality by altering community composition. Bacterivores and fungivores at the intermediate trophic level have the strongest influence on soil multifunctionality, highlighting the importance of trophic position in determining soil ecosystem functions.

Ericoid shrubs shape fungal communities and suppress organic matter decomposition in boreal forests

Nicolas Fanin et al.

Summary: The study found that the removal of ericaceous shrubs and associated ERI changed the composition of EMF communities, with larger effects occurring at earlier stages of the chronosequence. Removal of shrubs was associated with enhanced N availability, litter decomposition, and enrichment of the recalcitrant OM fraction. Increasing abundance of slow-growing ericaceous shrubs and the associated fungi contributes to increasing nutrient limitation, impaired decomposition, and progressive OM accumulation in boreal forests, particularly towards later successional stages.

Adaptation of soil micro-food web to elemental limitation: evidence from the forest-steppe ecotone

Bing Li et al.

Summary: Stoichiometric imbalance between resources and decomposers can affect soil microbial communities and nutrient cycling. This study examines how soil micro-food web responds to elemental limitations in an ecotone. The results show that soil microbial investment in resource acquisition shifts with decreasing C:N:P ratios, and the composition of the micro-food web changes as well. Cooccurrence networks become less complex and stable with decreasing C:N:P ratios, indicating a role of C-limitation in soil food web structure.

Increasing rates of long-term nitrogen deposition consistently increased litter decomposition in a semi-arid grassland

Shuang-Li Hou et al.

Summary: Continuing nitrogen deposition accelerates litter decomposition by increasing soil manganese availability, lowering soil pH, reducing soil C : N ratios, and subsequently increasing bacterial to fungal ratios. Multiple factors contribute to higher rates of litter decomposition in response to nitrogen deposition.

Emergent properties of microbial communities drive accelerated biogeochemical cycling in disturbed temperate forests

Ernest D. Osburn et al.

Summary: Researchers studied microbial community structure and ecosystem functioning in disturbed and undisturbed forest soils at the Coweeta Hydrologic Laboratory. The results showed that disturbed soil microbial communities were associated with ecosystem functioning, particularly in carbon and nitrogen cycling process rates. While few ecosystem functions were related to microbial alpha diversity, all functions were associated with microbial community composition metrics.

Home-field advantage of litter decomposition: from the phyllosphere to the soil

Nicolas Fanin et al.

Summary: Plants often benefit from specialized decomposer communities, known as the 'home-field advantage', which increase the breakdown of plant litter. When the phyllosphere communities are removed, the 'home-field advantage' effects are reduced. Priority effects and interactions between phyllosphere and soil organisms play a role in explaining the positive effects of the phyllosphere at home.
