Canopy and Understory Nitrogen Addition Alters Organic Soil Bacterial Communities but Not Fungal Communities in a Temperate Forest

open access: yesFrontiers in Microbiology, 2022
Atmospheric nitrogen (N) deposition is known to alter soil microbial communities, but how canopy and understory N addition affects soil bacterial and fungal communities in different soil layers remains poorly understood.

Land-use intensity indirectly affects soil multifunctionality via a cascade effect of plant diversity on soil bacterial diversity

open access: yesGlobal Ecology and Conservation, 2020
Land-use intensification impairs multiple soil ecosystem functions and services (hereafter ‘soil multifunctionality’; SMF) crucial to human wellbeing by influencing plant diversity and soil microbial communities. However, available information is limited

Diversity rankings among bacterial lineages in soil [PDF]

open access: yesThe ISME Journal, 2008
Abstract We used rarefaction curve analysis and diversity ordering-based approaches to rank the 11 most frequently encountered bacterial lineages in soil according to diversity in 5 previously reported 16S rRNA gene clone libraries derived from agricultural, undisturbed tall grass prairie and forest soils (n=26,140, 28 328, 31 818, 13 ...

Soil bacterial community responses to short-term grazing exclusion in a degraded alpine shrubland – grassland ecotone

open access: yesEcological Indicators, 2021
Grazing exclusion by fencing is a common and effective grassland management strategy for degraded grassland restoration. Soil bacteria, the most important decomposers of soil organic matter, is the linkage between plant and soil.

Effects of precipitation changes on soil bacterial community composition and diversity in the Junggar desert of Xinjiang, China [PDF]

open access: yesPeerJ, 2020
Variation in precipitation can markedly affect the structure and function of soil microbial communities, especially in arid areas which are limited by water resources.

pH-Related Changes in Soil Bacterial Communities in the Sanjiang Plain, Northeast China

open access: yesMicroorganisms, 2023
Soil bacteria are crucial components of terrestrial ecosystems, playing an important role in soil biogeochemical cycles. Although bacterial community diversity and composition are regulated by many abiotic and biotic factors, how soil physiochemical ...

Legacy effects of fumigation on soil bacterial and fungal communities and their response to metam sodium application

open access: yesEnvironmental Microbiome, 2022
Background Soil microorganisms are integral to maintaining soil health and crop productivity, but fumigation used to suppress soilborne diseases may affect soil microbiota.

Responses of Bacterial Communities in Soils under Winter Wheat to Nightly Warming and Nitrogen Addition

open access: yesAgronomy, 2022
Understanding soil bacterial diversity under global warming is necessary because of its crucial role in soil nitrogen cycling. However, the interaction effect of warmer temperatures and nitrogen application on bacterial communities in the soils of winter

Bacterial Diversity in Agricultural Soils during Litter Decomposition [PDF]

open access: yesApplied and Environmental Microbiology, 2004
ABSTRACT Denaturing gradient gel electrophoresis (DGGE) of amplified fragments of genes coding for 16S rRNA was used to study the development of bacterial communities during decomposition of crop residues in agricultural soils. Ten strains were tested, and eight of these strains produced a single band.
