“…However, some direct links might take place. For example, allelopathy, included as a toxicity impact, might increase plant competition by influencing soil nutrient availability (Inderjit & del Moral 1997;Medina-Villar & al. 2017); competition with native plants also changes species composition and diversity, and thus, succession and habitat structure (Schoener 1974).…”

Urban parks and gardens are one of the most important pathways for the deliberate introduction of non-native plant species, some of which cause environmental and socioeconomic impacts. We conducted a risk assessment on 388 non-native woody plant species from 46 urban parks of mainland Spain to classify them in lists based on their invasion status, being invasive elsewhere, climate matching with the area of origin, and potential to cause negative impacts. Only Ficus benjamina has no potential to invade (Green list). Four species are invasive and regulated (Priority list); 47 invasive or potentially invasive species can cause more impact types than the median value (Attention list), while 12 can cause less impacts than the median (Watch list). There is no park without any invasive or potentially invasive species. The most common potential impacts could be competition with native species (80% species) and the physical modification of the habitats (71%). We also identified 31 species with potential to cause human health impacts. Some species could cause several impact types. The most correlated potential impacts are among competition, toxicity, and alteration of natural succession and habitat structure. The most frequently planted invasive and potentially invasive species are the ones with the largest standard trending value from Google Trends, and therefore the ones with more societal interest.

“…As a result, our third hypothesis, late-successional forest soils exhibit stronger allelopathic inhibition to P. americana than early successional soils, was not supported. Thus, differences in the species composition of communities, which leads to species-specific allelopathic effects on invasive species, may be a more promising explanation [8,25,66] than succession.…”

“…Despite this concern, activated carbon, due to its effectiveness in absorption of allelochemicals, is still utilized by many researchers to neutralize allelochemicals in order to study the allelopathy of plants [21,36,37,39,72]. Additionally, caution should be exercised when using laboratory bioassays to simulate a complex field environment [66,73]. The now documented contrasting allelopathic effects between soils from natural forests and the plantation warrant further research to characterize the involved allelochemicals and their effects throughout the entire life span of invasive plants.…”

Due to increasing globalization and human disturbance, plant invasion has become a worldwide concern. Soil characteristics associated with the vegetation of recipient communities affect plant invasion success to a great extent. However, the relative importance of soil biotic and abiotic factors of different recipient communities in resisting plant invasion is not fully understood. We hypothesized that natural forest soils can better resist plant invasion than can plantation soils, that the allelopathic legacy of resident trees in soil plays a role in resisting invasive plants, and that late-successional soils have a strong effect. We examined the effects of soil and litter collected from four natural forests at successional stages and one Robinia pseudoacacia Linn. plantation in eastern China on the growth of Phytolacca americana L., which is a highly invasive species across China, and explored the individual effects of soil nutrients, allelochemicals, and soil microbes. We found that allelopathic activity of natural forest soils can effectively resist P. americana invasion, and that low level of nutrients, especially of phosphorus, in the soils might be potential limiting factors for the plant growth. The profound conditioning of soil resources by exotic R. pseudoacacia based on tree traits (including allelopathy) facilitated further P. americana invasion. Allelochemicals from forest litter inhibited the germination of P. americana seeds, but pH played a major role in P. americana growth when these substances entered the soil. However, we have no evidence that late-successional forest soils exhibit strong allelopathy toward P. americana. The present study will help to further our understanding of the mechanism of community resistance to invasion.

“…The persistence of allelochemicals in soil environment is an important factor [50]. It has been found that the allelopathic potential of black locust against understorey species is modulated by soil as the phytotoxic compounds are absorbed into the soil organic matter and clays and/or are modified by soil microorganisms [51].…”

Research Highlights: Plant cover drives the activity of the microbial decomposer community and affects carbon (C) sequestration in the soil. Despite the relationship between microbial activity and C sequestration in the soil, potential inhibition of soil microbial activity by plant cover has received little attention to date. Background and Objectives: Differences in soil microbial activity between two paired stands on soil at a very early stage of formation and a common story until afforestation, can be traced back to the plant cover. We hypothesized that in a black locust (Robinia pseudoacacia L.) stand the high-quality leaf litter of the tree, and that of the blackberry (Rubus fruticosus L.) understory had an inhibitory effect on soil microbial community resulting in lower mineralization of soil organic matter compared to the paired black pine (Pinus nigra Arn.) stand. Materials and Methods: We estimated potential mineralization rates (MR), microbial (MB), and active fungal biomass (AFB) of newly-shed litter, forest floor, and mineral soil. We tested the effects of litters' water extracts on soil MR, MB, AFB and its catabolic response profile (CRP). Results: Newly-shed litter of black locust had higher MR than that of blackberry and black pine; MR, MB, and AFB were higher in forest floor and in mineral soil under black pine than under black locust. Water extracts of black locust and blackberry litter had a negative effect on the amount, activity of microorganisms, and CRP. Conclusions: The results demonstrate the potential for black locust and blackberry litter to have a marked inhibitory effect on decomposer microorganisms that, in turn, reduce organic matter mineralization with possible consequences at the ecosystem level, by increasing C sequestration in mineral soil.
