“…Invasive weed species have the potential to release allelopathic substances to the surrounding environments to suppress their neighboring competing plants [ 11 , 12 , 13 , 14 , 15 ]. Parthenium hysterophorus L. has taken the shape of a noxious weed and is becoming a threat to crop production, animal husbandry and human health due to its strong allelopathic effects [ 16 , 17 , 18 , 19 ].…”

The allelopathic effect of various concentrations (0, 6.25, 12.5, 50 and 100 g L−1) of Parthenium hysterophorus methanol extract on Cyperus iria was investigated under laboratory and glasshouse conditions. No seed germination was recorded in the laboratory when P. hysterophorus extract was applied at 50 g L−1. In the glasshouse, C. iria was mostly injured by P. hysterophorus extract at 100 g L−1. The phytochemical constituents of the methanol extract of P. hysterophorus were analyzed by LC-ESI-QTOF-MS=MS. The results indicated the presence of phenolic compounds, terpenoids, alkaloids, amino acids, fatty acids, piperazines, benzofuran, indole, amines, azoles, sulfonic acid and other unknown compounds in P. hysterophorus methanol extract. A comparative study was also conducted between P. hysterophorus extract (20, 40 and 80 g L−1) with a synthetic herbicide (glyphosate and glufosinate ammonium at 2 L ha−1) as a positive control and no treatment (negative control) on Ageratumconyzoides, Oryzasativa and C. iria. The growth and biomass of test weeds were remarkably inhibited by P. hysterophorus extract. Nevertheless, no significant difference was obtained when P. hysterophorus extract (80 g L−1) and synthetic herbicides (glyphosate and glufosinate ammonium) were applied on A.conyzoides.

“…The rapid pace of IAPs infestation in the Anthropocene perturbed the biotic and abiotic components of the environment (El-Barougy et al 2021;Rathee et al 2021). To this end, the IAPs have driven the environmental degradation by changing nutrient and pollutant cycling, habitat structure, microbial diversity; hydro-morphology, soil chemistry, water and disturbance regimes (Pyšek et al 2020;Qu et al 2021). In contrast, Gao et al (2020) studied the effects of soil attributes on IAPs and revealed that soil nutrient heterogeneity has driven the growth of plant invaders.…”

“…Several IAPs such as Eichhornia crassipes and Salvinia molesta can adversely influence the productivity of paddy fields (Kariyawasam et al 2021). Allelochemic compounds released from IAPs (e.g., Rhus typhina) adversely influenced the growth of cultivated plant such as Tagetes erecta (Qu et al 2021). Furthermore, IAPs in concert with climate change have remarkably affected the global agricultural systems (Ziska et al 2011;Paini et al 2016) and hence impose adverse implications on food security.…”

“…In addition to environmental pollution, the alteration of ecological complexity and soil resources through invasive alien plants (IAPs) is a pervasive threat to native biodiversity while accelerating the overall process of environmental degradation (Stanek et al 2020;Allen et al 2021;Qu et al 2021). International trade through several global routes was considered to be the prime drivers in the spread of biotic invaders (Hulme 2021).…”

Environmental Degradation by Invasive Alien Plants in the Anthropocene: Challenges and Prospects for Sustainable Restoration

Biodiversity, soil, air, and water are the vital life-supporting systems of this planet Earth. However, the deliberate and accidental introduction of invasive alien plants (IAPs) in the Anthropocene majorly due to the global international trade perturbed the homeostasis of our biosphere. IAPs are considered as one of the major drivers of biodiversity loss and ecosystem degradation. The pervasive threats of IAPs to environmental sustainability and biosecurity are further exacerbated under the COVID-19 pandemic. The environmental disturbances resulting from IAPs can be attributed to several mechanisms/ hypothesis (e.g., novel weapon (NW), enemy release (ER), and evolution of increased competitive ability (EICA), efficient reproductive attributes, and phenotypic plasticity, etc.) deployed by IAPs. Nevertheless, the interrelationship of IAPs with environmental degradation and restoration remain elusive especially in terms of ecological sustainability. Moreover, there is a dearth of studies which empirically assess the synergies of IAPs spread with other anthropogenic disturbances such as climate and land-use change. In this context, the present review is aimed to depict the impacts of IAPs on environment and also to assess their role as drivers of ecosystem degradation. The restoration prospects targeted to revitalize the associated abiotic (soil and water) and biotic environment (biodiversity) are also discussed in detail. Furthermore, the effects of IAPs on socio-economy, livelihood, and plant-soil microbe interactions are emphasized. On the other hand, the ecosystem services of IAPs such as associated bioresource co-benefits (e.g., bioenergy, phytoremediation, biopolymers, and ethnomedicines) can also be vital in sustainable management prospects. Nevertheless, IAPs-ecological restoration interrelationship needs long-term pragmatic evaluation in terms of ecological economics and ecosystem resilience. The incorporation of 'hybrid technologies', integrating modern scientific information (e.g., 'biorefinery': conversion of IAPs feedstock to produce bioenergy/biopolymers) with traditional ecological knowledge (TEK) can safeguard the environmental sustainability in the Anthropocene. Importantly, the management of IAPs in concert with circular economy principles can remarkably help achieving the target of UN Sustainable Development Goals and UN-Decade on Ecosystem Restoration.

“…One of the challenges of globalization is biotic exchange (Reaser et al, 2007). Occurring at increasing rates and volumes, the consequences of invasive species dispersed beyond their natural barriers often harm native biodiversity and impair different functions of socio-biological systems (Sala et al, 2000;Walsh et al, 2016;Qu et al, 2021). Yet, impacts of concurrent multiple invasions remain poorly understood.…”

Despite increasing evidence indicating that invasive species are harming ecological systems and processes, impacts of multiple invasions, and the linkages between these events and changes in vegetation and soil are inadequately documented and remain poorly understood. Addressing multiple invasions would help to highlight high priority invaders and would aid in designing more effective control strategies, contributing to environmental restoration and sustainability. In this work, we tested the impact of three concurring invasive plant species, Amorpha fruticosa, Fraxinus pennsylvanica and Acer negundo, on soil conditions and native plant diversity. The research was conducted in riparian ecosystem and included the following treatments: (1) co-occurrence of the three invasive plant species, (2) occurrence of a single invasive species, and (3) control, i.e., absence of invasive species. Our findings revealed that the impact of invasive plants on soil properties and native plant diversity is magnified by their co-occurrence. Soil in mixed plots (those populated with all three invaders) contained much higher levels of nitrifying bacteria (NB), organic matter (Om), nitrogen (N), and carbon (C) as well as lower carbon to nitrogen ratio (C:N) levels, compared to single species invaded plots and control plots. Mixed plots were also characterized by reduced native plant diversity compared to single species invaded and control plots. Differences in soil conditions and native plant diversity revealed the interactive potential of invasive plants in depleting biodiversity, and thus in affecting ecological and biogeochemical processes. Our results highlight the need to study the impact of multispecies invasion and suggest that sites in riparian areas affected by co-occurring invaders, should be prioritized for ecosystem restoration.
