Опубликована: Март 13, 2025

Abstract Tidal wetland reclamation is a worldwide issue that profoundly alters ecological functions and ecosystem service provisions; however, its impacts on sediment microbial communities remain poorly understood. Here, we investigated the spatial seasonal patterns of greenhouse gas (GHG) production in response to land use change mangrove wetlands elucidated underlying mechanisms by integrating environmental parameters community characteristics. In time period studied, substantially reduced organic matter content, richness diversity, CO 2 rates. Converting mangroves drier cover types, namely orchard vegetable field, significantly diminished reducing substrates (sulfide, Fe 2+ , NH 4 + ), network complexity stability, CH rates, while increasing N O contrast, these showed opposite trend following conversion flooded aquaculture pond. Overall GHG rate was 399.8 mg e kg −1 d which respectively decreased 68.83%, 69.86%, 30.84% orchard, Microbial stability were strongly related rates O, rather than can be better indicators specialized (CH production). Therefore, preserving “interaction” could important mitigate negative effects diversity loss caused human activities aquatic environments. Future research should consider conditions composition, interactions, gain comprehensive understanding functions.

Effects of humic acid fertilizer on the growth and microbial network stability of Panax notoginseng from the forest understorey

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Авг. 1, 2024

Humic acid (HA) can substantially enhance plant growth and improve soil health. Currently, the impacts of HA concentrations variation on development quality Panax notoginseng (Sanqi) from forest understorey are still unclear. In this study, exogenous was administered to roots Sanqi at varying (2, 4, 6 ml/L). Subsequently, diversity community structure bacteria fungi were assessed through high-throughput sequencing technology. The investigation further involved analyzing interplay among sanqi, edaphic factors, microbial network stability. Our finding revealed that moderate (4 ml/L) improved fresh/dry weight NO3-−N levels. Compared with control, had a notable impact bacterial fungal communities compositions. However, there no significant difference in α β fungi. Moreover, abundance beneficial (Bradyrhizobium) harmful (Xanthobacteraceae) increased decreased 4 ml/L HA, respectively, while stability enhanced. Structural equation model (SEM) fresh factors directly affected HA. conclusion, is for promoting quality. study provides reference increasing yield sustainable Sanqi-pine agroforestry system.

Synergistic effects of rhizosphere effect and combined organic and chemical fertilizers application on soil bacterial diversity and community structure in oilseed rape cultivation

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Март 14, 2024

The combined application of chemical and organic fertilizers has been recognized to enhance soil fertility foster the microbial ecosystem. However, optimal ratio in oilseed rape cultivation is still uncertain, role rhizosphere effect unclear. Thus, this study aimed elucidate impacts varying ratios on structure potential functionalities non-rhizosphere communities. interplay communities with properties root exudates was investigated controlled pot cultivations receiving fertilizers. Results indicated clear segregation bacterial community, influenced by both fertilization treatments effects. community significantly correlated nitrate nitrogen, acids, dissolved carbon (DOC) content. Rhizosphere effects led increased bacteria abundance, reduced diversity, decreased network stability. Notably, F3 treatment 25% 75% showed a higher abundance at 1.43 × 10 11 copies g −1 dry soil, accompanied species genetic ecological complexity. This also yielded highest aboveground biomass rape. risk plant pathogenicity. reveals impact function, shedding light establishment more effective schemes for agriculture.

Reducing Application of Nitrogen Fertilizer Increases Soil Bacterial Diversity and Drives Co-Occurrence Networks

Microorganisms, Год журнала: 2024, Номер 12(7), С. 1434 - 1434

Опубликована: Июль 15, 2024

Reducing nitrogen fertilizer application highlights its role in optimizing soil bacterial communities to achieve sustainable agriculture. However, the specific mechanisms of community change under these conditions are not yet clear. In this study, we employed long-term field experiments and high-throughput sequencing analyze how varying levels influence structure co-occurrence networks. The results show that reducing inputs significantly enhances diversity evenness communities, possibly due diminished dominance nitrogen-sensitive taxa, which turn liberates ecological niches for less competitive species. Furthermore, changes complexity stability networks suggest increased resilience a shift toward more mutualistic interactions. These findings underline potential reduced alleviate pressures among species, thereby promoting diverse stable microbial ecosystem, highlighting release fostering diversity. This research contributes our understanding management can health offers insights into agricultural practices.

Simulated wind erosion and local dust deposition affect soil micro-food web by changing resource availability

Ecological Processes, Год журнала: 2025, Номер 14(1)

Опубликована: Янв. 2, 2025

Abstract Background Wind erosion and dust deposition are the most common natural geological process in arid semiarid areas. They significantly affect redistribution of soil nutrients ecosystem functioning services. However, effects wind on micro-food web still poorly understood. Therefore, we conducted a field manipulative experiment to investigate response microbial nematode communities, energy channels their cascade grassland. Results Our results showed that had no effect abundance microbes nematodes, but altered community composition food web. increased fungivore channel index, leading fungal-dominated channel, i.e., slow channel. Dust dissolved organic carbon, phospholipid fatty acids abundance, showing strong bottom-up trophic by increasing quantity resource. Compared with control treatment, both declined complexity stability Conclusions findings offer new insight for exploring aeolian web, which can provide parameter estimation accurate evaluation function.
