Summary: Soil microorganisms play a crucial role in biogeochemical cycles, but their response to fires is not well understood. A global meta-analysis of 371 cases from 81 published studies was conducted to explore the comprehensive effects of fires on soil microbial properties. The results show that fires increase microbial metabolic quotient and decrease soil microbial biomass carbon and fungal biomass. The intensity of the fire and ecosystem types and climate zones also impact these responses.

Summary: The carbon and nutrients in soil microbial biomass and their proportion in soil elements, known as soil microbial quotient, are key indicators of soil quality and respond quickly to changes in land-use patterns. Agriculture significantly decreases soil microbial biomass and quotient compared to grassland, with some improvement in microbial biomass after agriculture abandonment. It is crucial to maintain natural grasslands to protect and maintain soil microbial biomass and quotient in the meadow steppe of northeast China.

Summary: A global meta-analysis was conducted to study the vertical changes of microbial biomass and diversity across soil profiles. It was found that microbial biomass and bacterial diversity decrease with soil depth. Soil pH, total organic carbon (TOC) and total nitrogen (TN) were identified as important factors influencing these changes.

Summary: Changes in vegetation from forest grassland to herb grassland in Guanshan grassland have led to a decline in soil microbial biomass and microbial activities. Soil pH, available nitrogen, organic carbon, total phosphorus, available phosphorus, and total nitrogen were key factors in this decline. Additionally, slope aspects have also impacted soil microbial properties, with the east slope showing higher microbial biomass and enzymatic activities compared to the west slope.

Summary: Soil carbon sequestration (SCS) refers to the uptake of carbon from the atmosphere and its storage in soil, with soil microbial community (SMC) playing a crucial role. Agricultural practices that improve SCS can alter SMC, soil organic matter, and soil aggregates. However, more research is needed to fully understand their contribution to SCS.

Summary: Intensive management has led to significant changes in natural forests, with increased conversion into economic plantations worldwide. The impacts of microbial disturbance during economic plantation remain unclear. This study used Escherichia coli O157:H7, a pathogenic species, to assess the effects of invasion on the soil microbial community under intensive management. The results showed that bamboo economic plantations altered soil properties, such as pH and community diversity, and had longer pathogen survivals compared to natural hardwood soils. The study highlights the need to quantify soil resilience and understand the potential risks to environmental and human health from intensive management.

Summary: Understanding the interactions between soil organic matter (SOM) dynamics and soil microbial communities is crucial for predicting the stability and fate of estuarine SOM after human disturbance. This study investigated the microbial communities and chemical composition of different SOM fractions in the Pearl River Estuary under various land uses. The results revealed that land use greatly influenced the quantity and quality of SOM fractions, with microbial communities playing a stronger role in shaping the chemical compositions of different SOM fractions compared to fungal communities. Bacterial diversity showed a stronger relationship with the chemical composition of water-extractable organic matter (WEOM) than abundance. These findings highlight the importance of microorganisms in determining the chemical composition of SOM fractions in estuarine environments.

Summary: The forest floor plays a critical role in the stability of forest ecosystems, with seasonal variations in litter decomposition rate contributing to biochemical and structural heterogeneity in carbon and nutrient cycling. The study found that microbial respiration was significantly higher in fall, winter, and spring, with lower microbial biomass observed in winter across all forest types. Microbial C use efficiency varied between forest stands and seasons, with strong correlations between litter layer characteristics and microbial biomass C/N ratios.

Summary: Climate change and land-use intensity impact soil microbial communities, with future climate conditions having less influence on soil microbes while management intensity of land-use has strong effects. Low-intensity management measures can promote soil ecosystem functions such as efficient carbon storage and nutrient cycling under different land-use and climate change scenarios.

Summary: This study compared the impacts of four afforestation and agroforestry practices on soil properties and bacterial communities with legacy cropping systems in China. The results showed that afforestation and agroforestry practices significantly increased soil organic carbon and total nitrogen levels while also enhancing bacterial diversity, with a greater effect on bacterial community beta diversity in the topsoil. Land conversion was found to be a key factor influencing taxonomic shifts and functional variations in bacterial communities, particularly in the topsoil.

Summary: Land-use change, specifically deforestation for agriculture, significantly impacts the taxonomic, phylogenetic, functional, and beta diversity of soil fungal communities, altering the relative abundance of different fungal phyla. After deforestation, there is a decrease in fungal diversity in arable soil compared to pasture soil, and a clear shift in fungal communities towards pathotrophs in the pasture and arable soil. Ectomycorrhizal fungi, associated with conifers, are negatively affected by deforestation, highlighting the importance of understanding fungal community changes for soil management and environmental impact assessment.

Summary: Conservation agriculture practices increase soil microbial diversity and functionality compared to conventional practices, affecting the structure of microbial communities. The rhizobiome of maize is different and more diverse than surrounding soil, and its diversity increases with plant growth. Agricultural practices only affect the maize rhizobiome in the early growth stages, potentially impacting maize plant development.

Summary: The application of organic material has a significant impact on soil microbial communities and functionality, particularly on bacterial and viral groups. Cellulose degraders are enriched in amended soil, while slow-growing oligotrophic bacteria and archaea are more abundant in unamended soil. The soil viral structure and richness are also affected by organic material application.

Summary: In this study, it was found that drought stress affected the diversity of fungal communities associated with castor bean roots and rhizosphere. The alpha and beta diversity of these communities increased under extremely dry conditions, but the species turnover decreased in the stressed roots. However, the association between castor bean and arbuscular mycorrhizal fungi was not affected by drought.

Summary: We investigated the presence and diversity of bacteria in the embryos of the viviparous lizard Sceloporus grammicus and their amniotic environment. Our results showed that bacterial 16S rRNA genes were present in the embryos, with a lower diversity compared to maternal tissues. Most of the bacterial species detected in the embryos were also found in the mother, suggesting a continuous transmission of bacteria from the mother to the embryos. The study highlights the possibility of microbiota vertical transfer during embryonic development and its potential impact on the development of the lizards.
