“…We found that N addition altered native and exotic species' Rii in certain conditioning treatments, but overall these effects were small and did not qualitatively alter the effects of maize–soybean soils. Such fertilization often specifically promotes exotic species in interactions with natives (Vasquez, Sheley & Svejcar ; Elgersma ), but in our experiment, we observed promotion of both native and exotic species. Importantly, we did find that N fertilization increased suppression of natives by exotics in soils conditioned by Bromus , suggesting that N fertilization may heighten soil‐legacy effects of some exotic species.…”

“…In soils with a history of annual crop production, high levels of soil nitrogen (N) may affect interspecific interactions, in addition to the effect of any other soil factors (Blumenthal, Jordan & Russelle ; Elgersma ). High soil N levels may result from previous fertilization or ongoing N applications to promote biomass production.…”

“…High soil N levels may result from previous fertilization or ongoing N applications to promote biomass production. Soil N levels can alter soil microbial community composition and function (Egerton‐Warburton, Johnson & Allen ; Elgersma ), either directly or indirectly (e.g. via changes in plant nutrient content).…”

Summary Semi‐natural perennial grasslands are of increasing importance as components of multifunctional agroecosystems, combining biomass production with provision of other ecosystem services. Soil legacies from previous land use or exotic species can hinder their establishment, but might be overcome through a multi‐stage successional strategy, whereby certain species are used to facilitate native grassland species establishment. We tested this strategy via a feedback experiment examining soil‐conditioning effects on interference interactions between native and exotic species. Soils in a former maize–soybean production field in Minnesota, USA, were conditioned for 3 years with native or invasive exotic perennials or a maize–soybean crop rotation. Nitrogen (N) fertilization was an additional treatment in field plots. In a greenhouse, native and invasive exotic perennial grassland seedlings were grown on these soils, in monoculture and in native–exotic species pairs, with and without N fertilization. The impact of soil conditioning and field and greenhouse N fertilization on interactions between native and exotic seedlings in mixture was determined. Neighbouring plants suppressed biomass production in all native and exotic species. The maize–soybean rotation left a soil legacy that enhanced suppression of native species when grown with exotic species, while exotic species suffered no such disadvantage. The strong and specific disadvantage to native species of maize–soybean soils decreased with greenhouse N fertilization, but remained significant, while field N addition did not alter this effect. Synthesis and applications. We found that the negative soil legacy of the maize–soybean rotation for native plant performance in interaction with exotics was greatly diminished in soils conditioned by native or exotic perennial species, irrespective of nitrogen addition. This highlights the potential value of perennial species in conversion from row‐crop agriculture to grasslands, because all perennial species alleviated the enhanced suppression of natives observed on maize–soybean soils. We did not find strong evidence that these perennial species were capable of specifically facilitating native species over exotics, but a broader range of species should be evaluated.

“…Considering soil microbial biota, the invasion of alien plants has been proved to enhance microbial diversity, downgrade the soil microbial quality or reduce the soil microbial activity of arbuscular mycorrhizal fungi and the abundance of sulfur-oxidizing functional genes (Duda et al 2003 He et al 2021). Exotic invasive plants may modify the soil pathogen communities and the underlying plant-soil feedbacks potentially in uences the invasion process (Elgersma 2014). Eppinga et al (2006) demonstrated that the growth of exotic species which gather more pathogens or herbivores is promoted if those exotic species can tolerate pathogens or herbivores, relative to the native plants.…”

Background and Aims Plant invasion can modify habitat characteristics for instance soil stoichiometry and microbial pattern. However, few studies concerned the effects of plant invasion on the soil properties in the urban ecosystem. The present study aims to explore the impact of aquatic plant invasion on sediment properties within the urbanization context. Methods First, population density and impervious surface area, were used to construct an urbanization gradient of river wetlands and divide the two rivers of Qingdao City, China – Zhangcun River and Wenquan River into urban and periurban types. Second, sediment samples were collected from the plots invaded by the aquatic plant invader, Alternanthera philoxeroides and its native neighbor, Typha angustifolia in urban and periurban rivers. Lastly, sediment properties were determined and a comparison was performed. Results First, a general similar fertility and stoichiometry was found between the sediment derived from the invasive and that from the native. Second, a higher bacterial diversity was found in the sediment derived from A. philoxeroides merely in the periurban river, while the higher bacterial diversity was merely shown for the Shannon’s diversity index of A. philoxeroides in the urban river. Third, A. philoxeroides shaped a novel soil microbial structure since more microbes relevant with nutrient cycling were accumulated compared to the native. Lastly, urbanization gradient affected the comparison between the invasive and native plants on soil properties. Conclusion The invasion of exotic aquatic plant altered the sediment microbial pattern to some extent and the potential plant-soil feedback needs further investigation.

Riparian wetlands suffer serious plant invasion. Natural habitats and disturbance are two prominent environmental factors affecting the invasion process of exotic riparian invaders. In this study, a noxious invasive riparian plant, Alternanthera philoxeroides, and its native congener, Alternanthera sessilis were cultivated in three different riparian soils with different statuses of disturbance by cow manure addition. After harvest, we measured plant morphological traits including the internode length (INL), rooted node number (RNN), specific leaf area (SLA) and leaf mass ratio (LMR), and physiological traits including the maximal quantum yield (Fv/Fm), chlorophyll content (Ct), leaf nitrogen content (Nmass), leaf carbon/nitrogen ratio (C/N ratio), leaf construction cost per leaf area (CCarea), and non‐structural carbohydrate content (NSCC). Fertilization was found to improve the performances of most traits for both species similarly. Both species shared some similarities in trait values of SLA, LMR, CCarea and NSCC, and trait plasticity in NSCC in unfertilized sediments and SLA, LMR, C/N ratio, and CCarea in fertilized sediments. Moreover, compared to A. sessilis, A. philoxeroides showed some advantages in trait values of RNN in unfertilized sediments and Ct, Nmass, and C/N ratio in the most fertile treatments, and trait plasticity in INL, RNN, SLA, Ct, Nmass, and CCarea across different sediments. In conclusion, the disturbance, trait similarities, and trait advantages likely promote the invasion success of A. philoxeroides.
