Abstract
Purpose
The invasive plant Flaveria bidentis (L.) Kuntze, known as the "ecological killer", poses a significant threat to the ecosystem stability due to its strong phenotypic plasticity and high fertility. Previous studies have reported a close relationship between plant invasion and soil microbial communities. This study aimed to gain a deeper understanding of the relationship between the invasion of F. bidentis, the diversity of soil microbial communities, and soil physiochemical properties.
Methods
In this study, we established a common garden experiment by planting F. bidentis and Chenopodium ficifolium Sm. separately and mixed, in Lanfang, China. We analyzed microbial communities in both bulk soil and rhizosphere soil using the high-throughput sequencing technology.
Results
The results showed that F. bidentis invasion significantly increased bacterial and fungal diversities in rhizosphere soil, irrelevant with or without the existence of native plant species. Meanwhile, F. bidentis increased the content of organic matter and ammonium nitrogen (NH4+) in bulk soil and decrease the content of NH4+ in rhizosphere soil. Significant correlations were observed between nitrogen contents or acid phosphatase and specific soil microbial communities.
Conclusions
These results underly that regardless of competition with native plants, the invasion of F. bidentis alters soil physicochemical properties and increases microorganism community diversity. This study establishes a theoretical foundation for further research on the invasion mechanisms of F. bidentis and provides valuable references for other studies about F. bidentis.
期刊介绍:
The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
