ABSTRACTPlant-soil feedbacks (PSFs) can influence plant competition via direct interactions with pathogens and mutualists or indirectly via apparent competition/mutualisms (i.e., spillover to cooccurring plants) and soil legacy effects. Presently, it is unknown how intraspecific variation in PSFs interacts with the environment (e.g., nutrient availability) to influence competition between native and invasive plants. We conducted a fully crossed multi-factor greenhouse experiment to determine the effects of soil biota, interspecific competition, and nutrient availability on biomass of replicate populations from one native and two invasive lineages of common reed (Phragmites australis) and a single lineage of native smooth cordgrass (Spartina alterniflora). Harmful soil biota consistently dominated PSFs involving all three P. australis lineages, reducing biomass by 10%, regardless of nutrient availability or S. alterniflora presence as a competitor. Spillover of soil biota derived from the rhizosphere of the two invasive P. australis lineages reduced S. alterniflora biomass by 7%, whereas soil biota from the native P. australis lineage increased S. alterniflora biomass by 6%. Interestingly, regardless of lineage, P. australis soil biota negatively affected S. alterniflora biomass when grown alone (i.e., a soil legacy), but had a positive impact when grown with P. australis, suggesting that P. australis is preferred by harmful generalist soil biota or facilitates S. alterniflora via spillover (i.e., apparent mutualism). Soil biota also reduced the negative impacts of interspecific competition on S. alterniflora by 13%, although it remained competitively inferior to P. australis across all treatments. Moreover, competitive interactions and the response to nutrients did not differ among P. australis lineages, indicating that interspecific competition and nutrient deposition may not be key drivers of P. australis invasion in North America. Taken together, although soil biota, interspecific competition, and nutrient availability appear to have no direct impact on the success of invasive P. australis lineages in North America, indirect spillover and soil legacies from P. australis occur and may have important implications for co-occurring native species and restoration of invaded habitats. Our study integrates multiple factors linked to plant invasions, highlighting that indirect interactions are likely commonplace in driving successful invasions and their impacts on the local community.

Plant invasion is significantly affected by environmental factors in the recipient habitats and affects the stability and sustainable development of society. The invasiveness of alien plants may be increased by anthropogenic-mediated disturbances, such as fluctuations in nutrients caused by excessive emissions of nitrogen (N) and phosphorus (P). To improve our understanding of the interactions between N and P fluctuations and invasive alien plants, the current report focuses on the biogeochemical behavior of N and P among invasive alien plants, native plants, and the soil within the plant–soil ecosystem. Our research, together with a synthesis of the literature, shows that fluctuations in N and P resources provide more opportunities and competitiveness for plant invasion. At the same time, the biogeochemical cycles of N and P are promoted because of their efficient and increased utilization and rate of release by invasive alien plants. However, there is no consensus on whether the N and P compositions of invasive species are different from those of the natives in their habitat. Quantitative studies that compare N and P contents in plant, litter, and soil between native plant communities and invaded communities on a global scale are an indispensable area of research focus for the future.

Soil Feedback

Plant invasion is a key element defining the community structure and dynamics and has become a major concern for the invasive plants to control the restoration of ecosystem diversity. In the same line of thought, soil microorganisms are also considered as a significant parameter of evolution and invasive plants' success. The variations usually overserved in the composition and structure of the soil microorganisms and the consequences of plant invasion. Therefore, understanding the concept of plant invasion and soil microorganism impact plant competition and plant-soil feedback would be a very important step forward in invasive plant control and ecosystem restoration. This review aims to provide a conceptual explanation of plant invasion, the role of soil microorganisms on plant growth and its effects on the native plant-soil feedback and also to demonstrate the importance of understanding the integrative soil microorganism impact on the competition between native and invasive plants along with its effects on plant-soil feedback.
