Summary: Future climate changes will affect the frequency and size of rainfall events in drylands, leading to potential impacts on soil microbial communities. A study on altered rainfall patterns over 12 years found that increased small rain events promoted microbial diversity and biomass, while large rain events did not consistently have the same effect.

Summary: The study found that increasing snow depth led to higher water content, while snow removal or reduction decreased nutrient and microbial biomass concentrations in both types of biocrust. The concentrations of nutrients and microbial biomass significantly decreased when snow depth doubled ambient conditions. Snow depth, crust type, and their interaction significantly influenced nutrient concentrations and microbial biomass.

Summary: In this study, the influence of sand burial on bacterial and fungal communities inhabiting cyanobacterial and mixed crusts was assessed using a long-term field experiment and high-throughput sequencing. The results showed that sand burial treatment altered the diversity, abundance, and composition of the microbial communities. Different indicator taxa were identified in unburied and buried crusts, suggesting that changes in soil properties caused by sand burial may be a possible cause of changes in bacterial and fungal community composition in biological soil crusts.

Summary: Soil water availability is a critical limitation for soil respiration and ecosystem functions in biological soil crusts of arid ecosystems. A 3-year field experiment in a desert shrub in northwestern China revealed that increased rainfall led to an increase in microbial biomass carbon and nitrogen, while soil organic carbon, total nitrogen, pH, and biological thickness remained relatively stable. Water addition significantly altered the bacterial community composition, with Actinobacteria increasing and Bacteroidetes and Cyanobacteria decreasing in abundance. The effects of soil physiochemical properties and bacterial community composition on soil respiration varied, with soil physiochemical properties having a larger impact.

Summary: This study investigated the effects of different perennial alfalfa cultivars on the characteristics and microbiome of the rhizosphere soil. The results showed that soil organic carbon and pH had the greatest impact on the composition of the rhizosphere microbial community. Additionally, soil properties were significantly correlated with soil bacterial communities. Partial least squares path modeling revealed that microbial biomass and community composition were the dominant determinants of soil nitrogen content in perennial alfalfa rhizosphere.

Summary: Microbial communities in biological soil crusts (BSCs), inhabitants of arid soils, show higher nitrogen fixation rates in their native environment or similar temperatures due to ecological specialization. Changes in environmental conditions can affect microbial communities, but the effect on ecosystem processes is not well understood. We evaluated this by studying BSCs from different desert ecosystems in Mexico and found that nitrogen fixation rates, community composition, and diversity depended on the origin of the communities and the environment they experienced. We interpret these results as legacy effects resulting from ecological specialization. Overall, our study suggests that BSCs do not exhibit functional redundancy in terms of nitrogen fixation.

Summary: Biocrusts in drylands play a crucial role in biological nitrogen fixation and release of gaseous reactive nitrogen. This study reveals the simultaneous occurrence of aerobic and anaerobic nitrogen transformations in small-scale gradients within biocrusts. These processes are critical for nitrogen emissions and may be influenced by future global change and land management.

Summary: The study investigated the responses of cyanobacterial communities in BSCs to different snow treatments and three snow stages in the Gurbantunggut Desert in China. The relative abundance of Cyanobacteria and other bacterial taxa were mainly affected by soil temperature and irradiance, while different cyanobacterial taxa showed varied responses to snowpack. Snowpack depth and duration altered soil properties, leading to niche selection and shifts in the cyanobacterial community structure.

Summary: The study explores the correlation between bacteria, fungi, and archaea in the carbon cycle during reversal of desertification. It was found that bacteria play essential roles in carbon degradation, fixation, and methane oxidation, while fungi mainly degrade lignin at the later stage of biological soil crusts development. This indicates a functional complementarity among these microorganisms involved in the carbon cycle during the reversal of desertification.

Summary: The study found that bacterial communities play an important role in phosphorus and sulfur cycles during the biological soil crust succession in desert ecosystems, especially in 61-year-old BSCs where the expression intensity of functional genes significantly increased. Furthermore, there is a significant synergy between the improvement of soil properties and the intensities of genes expression related to phosphorus and sulfur cycles.

Summary: Investigations into the impact of heavy metals on microbial community structure revealed that heavy metals and chemical properties are the main driving forces behind changes in bacterial diversity and community structure in contaminated soils. The relative abundances of specific bacterial phyla were found to be correlated with the levels of heavy metals and certain chemical properties in the soils. Certain bacterial species identified in these specific tailing soils may have potential tolerance to heavy metals, providing theoretical support for future bioremediation efforts.

Summary: The study revealed that the development of biological soil crusts in desert ecosystems significantly increased the diversity of genes associated with microbial Fe cycling and the available Fe content. Fe(II) oxidation is mainly driven by the iro gene, while Fe(III) reduction is mainly driven by c-type cytochromes regulated by the OmcS gene. Additionally, fungal abundance, soil nutrient content, and the presence of Fe-manganese oxide fractions were identified as the main factors influencing the gene profile associated with microbial Fe cycling in BSCs.

Summary: This study investigated the soil factors influencing the development of biological denitrification inhibition (BDI) and found that initial soil moisture, ammonium concentration, and the initial abundance of certain microbial genes play significant roles in BDI development. Additionally, the research highlighted the relevance of biotic factors in explaining BDI and proposed the use of procyanidin concentration from plant belowground system as a new proxy for measuring BDI intensity.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
