Summary: Climate change-induced treeline shifts can affect soil organic matter mineralization, but the specific effects remain uncertain. This study investigated soil priming effects in high altitude and high latitude soils, and found that substrate additions can elicit both positive and negative priming effects. Positive priming was more pronounced above the treeline and in mineral soils, while negative priming dominated in other soil types. These findings are important for understanding soil carbon cycling and the impacts of climate change on soil carbon balance.

Summary: Plant traits, specifically higher rhizosphere respiration and root N concentration, play a key role in regulating the rhizosphere priming effect (RPE). Leaf traits and root morphological or architectural traits could not explain the interspecific variation in the RPE. Nitrogen fertilization affects the RPE through its interaction with plant traits and its effect on soil processes. Overall, our results highlight the importance of plant traits in predicting soil organic matter decomposition through plant-soil interactions.

Summary: Microbial community structure plays a critical role in soil organic carbon decomposition and rhizosphere priming effects (RPEs) during plant growth. However, the regulation of bacterial community structure on RPEs in soil and their response to plant growth remains uncertain. In this study, we investigated the RPE response to plant growth and nitrogen addition in a paddy soil-maize system and explored the underlying biotic mechanisms using 16S rRNA sequencing techniques. Our results showed that the bacterial community structure changed significantly during plant growth stages, and the different modules of bacterial community networks were associated with RPE pattern variation. Keystone taxa with different carbon utilization strategies were significantly different between growth stages and closely related to RPE patterns. This study provides valuable insights into the network structure of bacterial communities and highlights the importance of keystone taxa in RPE variation.

Summary: This study investigated the differences in bacterial communities between seagrasses and bulk sediments in Chilika, a brackish water coastal lagoon of India. The results showed that seagrasses had an effect on the diversity, composition, and abundances of benthic bacterial communities. Seagrasses supported higher bacterial abundances compared to bulk sediments, and the interactions and connectedness among seagrass bacterial communities were stronger. Seagrasses and environmental factors were the major drivers of benthic bacterial community composition. Heterotrophic bacteria in seagrass sediments showed higher metabolic diversity and activity than in bulk sediments, and seagrass sediments enhanced the utilization of carbon substrate guilds. Seagrasses play crucial roles in the organic matter cycling and degradation of hydrocarbon and xenobiotics in coastal sediments.

Summary: Biodiversity is crucial for ecosystem functions and services. While there have been many studies on biodiversity-ecosystem functioning (BEF) relationships in plant and animal systems, it remains unclear if such a relationship exists and how it evolves in microbial systems. In this study, synthetic denitrifying communities (SDCs) were constructed using 12 Shewanella denitrifiers with varying species richness. The results showed a positive correlation between community richness and functions, but this correlation was only significant in earlier stages of the evolution experiment. Additionally, community functions generally increased throughout the experiment, with lower richness communities showing greater increases and positive BEF relationships largely attributable to complementary effects.

Summary: This study identified FeS as a major catalyzing matter for the abiotic dechlorination of chloroethenes (CEs) in soil. Acetylene was found to be an indicator of FeS-mediated abiotic CE dechlorination. Organohalide-respiring bacteria (OHRB)-mediated dechlorination enhanced the conversion of CEs to acetylene, while FeS inhibited OHRB-mediated dechlorination and its inhibition could be alleviated by the addition of soil humic substances. Sulfate-reducing bacteria and fermenting microorganisms affected FeS-mediated abiotic dechlorination by re-generating FeS and providing short chain fatty acids, respectively. These findings provide insights into the interactions between abiotic and biotic dechlorination processes in soil and can guide the sustainable management of CE-contaminated sites.

Summary: In this study, the epiphytic microbial communities on G. lemaneiformis and the free-living microbial communities in the surrounding seawater were analyzed using 16S rRNA gene and ITS amplicon sequencing. The dominant epiphytic taxa were found to be associated with the seaweed and the degradation of algal polysaccharides. Enriched genes in the epiphytic community were related to stress responses, biofilm formation, and antifouling on the seaweed surface. The assembly of the epiphytic microbial community was predominantly determined by homogeneous selection. This study provides new insights into the epiphytic communities of G. lemaneiformis and offers guidance for future studies on microbe-seaweed interactions.

Summary: This study reveals that the spread of antibiotic and metal resistance genes is mainly due to selection pressure in human-influenced environments, and the role of biotic and abiotic factors in mediating their distribution in mangrove sediments is unclear. The results show that multidrug-resistance and multimetal-resistance are the most abundant classes of resistance genes, and their abundance decreases with sediment depth. Bacterial diversity is found to be negatively correlated with the abundance and diversity of resistomes. This study highlights the important role of biodiversity in driving the abundance and diversity of resistance genes.

Summary: This study used 16S and 18S rRNA gene sequencing to investigate the diversities and assembly of abundant and rare bacterial and protistan subcommunities in a karst river ecosystem. The rare subcommunities exhibited a similar biogeography to their abundant counterparts. Distance-decay patterns were observed in all components of bacterial and protistan subcommunities, with the rare subcommunities showing a more pronounced pattern. Dispersal limitation processes rather than heterogeneous selection strongly structured the abundant and rare bacterial and abundant protistan subcommunities. Bacteria, temperature, elevation, and conductivity were identified as the primary drivers for both abundant and rare subcommunities. Moreover, the rare subcommunities were found to contribute significantly to the persistence and stability of microbial networks in the river.

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.
