Atmospheric methane (CH4) arises significantly from wetlands, which are vulnerable to global climate shifts. As one of the most essential ecosystems, alpine swamp meadows, representing around fifty percent of the natural wetlands on the Qinghai-Tibet Plateau, were highly valued. The methane producing process is a function performed by methanogens, important functional microbes. Nevertheless, the methanogenic community's response, and the key pathways for CH4 production, to rising temperatures within alpine swamp meadows at various water levels in permafrost wetlands remain uncertain. This research delved into the effects of temperature increases on the production of methane in soil and the shifts in the methanogenic community, using alpine swamp meadow soil specimens with various water levels from the Qinghai-Tibet Plateau. Anaerobic incubation experiments were conducted at 5°C, 15°C, and 25°C. Biomass segregation A rise in incubation temperature yielded a corresponding increment in CH4 content, resulting in CH4 concentrations five to ten times larger at high-water-level sites (GHM1 and GHM2) in comparison with those at the low water level site (GHM3). The methanogens at the high-water-level sites (GHM1 and GHM2) showed little sensitivity to the changes in incubation temperature. The methanogen groups Methanotrichaceae (3244-6546%), Methanobacteriaceae (1930-5886%), and Methanosarcinaceae (322-2124%) held significant dominance; a pronounced positive correlation (p < 0.001) was observed between the abundance of Methanotrichaceae and Methanosarcinaceae and CH4 production levels. Changes in the methanogenic community structure were substantial at the GHM3 site (low water level) at a temperature of 25 degrees Celsius. Within the methanogen communities, Methanobacteriaceae (5965-7733%) were the dominant group at 5°C and 15°C. In contrast, Methanosarcinaceae (6929%) held a prominent position at 25°C, showing a statistically significant positive correlation with the rate of methane production (p < 0.05). The warming process, coupled with varying water levels in permafrost wetlands, reveals insights into methanogenic community structures and CH4 production, as evidenced by these findings collectively.

Plant roots, through exudates, release into the soil a variety of metabolites, including ginsenosides, as seen in the ginseng root. Despite this, there is limited understanding of the ginseng root exudate's influence on the soil's chemical and microbial characteristics. The influence of progressively higher ginsenoside concentrations on the soil's chemical and microbial attributes was the focus of this study. Soil chemical properties and microbial characteristics were investigated via chemical analysis and high-throughput sequencing following the introduction of 0.01 mg/L, 1 mg/L, and 10 mg/L concentrations of ginsenosides. Applying ginsenosides produced substantial changes in soil enzyme activities; consequently, the physicochemical properties, largely governed by soil organic matter (SOM), were significantly diminished. This in turn impacted the structure and composition of the soil microbial community. Ginsenosides at a concentration of 10 mg/L markedly increased the relative frequency of pathogenic fungi, including Fusarium, Gibberella, and Neocosmospora. Ginseng root exudates' ginsenosides, as revealed by these findings, might be associated with increased soil degradation during cultivation, thus driving future research to explore the mechanisms of interaction between these compounds and soil microbial communities.
