Summary: Soil carbon burial is crucial for mangroves to function as carbon sinks, however, the contribution of allochthonous or autochthonous inputs to the soil carbon pool remains uncertain. This study constructed carbon budgets to estimate mangrove-derived carbon burial rates for two species (K. obovata and A. marina) with different root structures. The results showed positive correlations between carbon burial rates and litterfall production, indicating that 14.8% and 10.9% of litterfall production rate can be used to estimate carbon burial rates for K. obovata and A. marina, respectively. Factors such as wind speed and precipitation were found to affect carbon burial in both species.

Summary: This study examined the growth and physiological responses of Kandelia obovata seedlings to different levels of arsenic (As) exposure. The results showed that the seedlings exhibited high tolerance to As exposure within a certain concentration range, with antioxidant enzymes playing a crucial role in resisting As toxicity. However, high concentrations of As inhibited seedling growth and led to increased malondialdehyde content and decreased antioxidant enzyme activities. It was also found that As mainly accumulated in the roots, and the translocation of As to the aerial parts of the seedlings was limited. Overall, K. obovata has the potential to be used as a remediation species in polluted coastal wetlands due to its high phytoextraction capacity and tolerance to As exposure.

Summary: This study proposes a method to assess the net carbon sink of marine macroalgae (Gracilaria) cultivation and predicts its future trends. The findings show that the net carbon sink of Gracilaria cultivation in China was about 32.1-92.4 kilotons per year from 2011 to 2020 and exhibits a significant annual growth trend. The predicted net carbon sink of Gracilaria cultivation is expected to increase to 77.8-191.4 kilotons per year from 2021 to 2030, which could contribute significantly to China's carbon peak goal. Furthermore, using Gracilaria for ruminant green feed production is predicted to reduce carbon emissions (methane) by 0.33-0.68 tons per ton of macroalgae.

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: 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.
