Feedbacks between plants and soil biota are increasingly identified as key determinants of species abundance patterns within plant communities. However, our understanding of how plant-soil feedbacks (PSFs) may contribute to invasions is limited by our understanding of how feedbacks may shift in the light of other ecological processes. Here we assess how the strength of PSFs may shift as soil mi...

Fuller, in 1989, described probiotic microorganisms as “a live microbial feed supplement,which beneficially affects the host animal, by improving its intestinal microbial balance”.Saccharomyces cerevisiae var. boulardii (S.boulardii) is an accurate probiotic yeast idol.The detection and budding of S.boulardiiis firmly related to the impression of healthinessto promote microorganisms from foodst...

Currently, characterization of soil microbial communities relies heavily on the use of molecular approaches. Independently of the approach used, soil DNA extraction is a crucial step, and success of downstream procedures will depend on how well DNA extraction was performed. Often, studies describing and comparing soil microbial communities are based on a single DNA extraction, which may not lea...

Nitrogen (N) fertilization may profoundly affect soil microbial communities. In this study, a field fertilization experiment was conducted in temperate grassland in Inner Mongolia, China to examine the effect of N fertilization on soil microbial properties and the main factors related to the characteristics of soil microbial community. Soil microbial biomass carbon (MBC) and microbial functiona...

Soils sequester and release substantial atmospheric carbon, but the contribution of fungal communities to soil carbon balance under rising CO2 is not well understood. Soil properties likely mediate these fungal responses but are rarely explored in CO2 experiments. We studied soil fungal communities in a grassland ecosystem exposed to a preindustrial-to-future CO2 gradient (250 to 500 ppm) in a ...

The effects of long-term reforestation on soil microbial communities and biomass are poorly understood. This study was conducted on two coniferous plantations: Cunninghamia konishii Hayata, planted 40 years ago (CONIF-40), and Calocedrus formosana (Florin) Florin, planted 80 years ago (CONIF-80). An adjacent natural broadleaf forest (BROAD-Nat) was used as a control. We determined microbial bio...

The efficacy of vegetative buffer strips (VBS) in removing herbicides deposited from surface runoff is related to the ability of plant species to promote rapid herbicide degradation. A growth chamber study was conducted to compare C-atrazine (ATR) degradation profiles in soil rhizospheres from different forage grasses and correlate ATR degradation rates and profiles with microbial activity usin...

12 Recent studies have identified the first-order representation of microbial decomposition as a 13 major source of uncertainty in simulations and projections of the terrestrial carbon balance. 14 Here, we use a reduced complexity model representative of current state-of-the-art models of 15 soil organic carbon decomposition. We undertake a systematic sensitivity analysis to 16 disentangle the ...

fungicides are most widely used pesticides in iran and the world. application of fungicides may affect the populations and activity of soil microorganisms, particularly fungi, with a consequence for soil fertility and crop growth. in the current study, the effects of different levels of metalaxyl on soil microbial biomass carbon (c) and nitrogen (n), microbial biomass c/n ratio and metabolic qu...

Rising temperatures are expected to reduce global soil carbon 1 (C) stocks, driving a positive feedback to climate change1–3. 2 However, the mechanisms underlying this prediction are not 3 well understood, including how temperature a ects microbial 4 enzyme kinetics, growth e ciency (MGE), and turnover4,5. 5 Here, in a laboratory study, we show that microbial turnover 6 accelerates with warming...
