The invasion of non-native plant species presents a significant ecological challenge worldwide, impacting native ecosystems and biodiversity. These invasive significantly affect the ecosystem. threat having harmful effects on natural ecosystem is serious concern. Invasive produce secondary metabolites, which not only help in growth development but are also essential for spread these species. This review highlights important functions metabolites invasion, particularly their effect allelopathy, defense system, interaction with micro soil biota, competitive advantages. Secondary produced by play an role affecting allelopathic interactions herbivory. They sometimes change chemistry to make viable condition proliferation. inhibit changing resources available them. Therefore, it necessary understand this complicated between invasion. mainly summarizes all known species, emphasizing significance integrated weed management research.

ABSTRACT Questions Degradation of facilitative interactions native species can play an important role in the establishment and expansion invasive plants communities. We evaluated relationship between level invasion Cynodon dactylon arbuscular mycorrhizal colonization Paspalum notatum Uruguayan grasslands, which were either extensively managed (natural vegetation [NG]) or oversown with exotic legumes fertilized phosphorus (NG + LP). Specifically, we investigated whether increasing levels associated reductions P. colonization, growth, nutrient content. Location grasslands Río de la Plata region. Methods Two paddocks 19 27 years under NG LP management selected contiguous to two management. In each paddock, collected nine monoliths (0.2 m diameter × 0.3 depth) that had percentages C. cover, classified as low (0%–10%), medium (30%–50%), high (70%–90%) levels. After 10 months uninterrupted shoot mass, nitrogen concentration, assessed plants. Results Mycorrhization decreased invasion. This was greater more intensively However, lower not aboveground growth concentration. Furthermore, at levels, similar LP, despite their contrasting soil P availability. Conclusions The presence mycorrhizae target grass negatively . Therefore, mutualism degradation might be a mechanism underlying success invading particularly those managed, albeit probably via nutritional effects.

Managed relocation is a critical tool for promoting ecological resilience in the face of climate change, and approach has been proposed restoration plant communities. Given that species poses some risk to recipient ecosystem, traits associated with invasiveness have as means assessing selecting candidate managed relocation. However, could also be relevant successful (and, turn, relocation)-particularly those linked establishment viable populations. Here, we review studies invasion ecology paired functional, ecological, biogeographic stages or ask which should used inform selection. We find substantial overlap between during population establishment, but divergence spread impacts, suggesting selection only focus on promote long-distance impact. Instead, few existing protocols utilize establishment. unintended harm from orders magnitude smaller than non-native introduction, focusing assessments likely exclude most able establish populations, causing failure rates recommend candidates invasive impacts are not necessary restoration. threats posed by balanced assessment does severely limit will best support adaptation strategy.

The soil microbiome can increase crop resilience to both abiotic and biotic stress, there is growing interest in uncovering the mechanisms by which we shape plant associated microbiomes yields within stressful environments. Through rhizodeposits, plants influence composition of microbial communities conditions rhizosphere, potentially generating plant-soil feedbacks nutrient availability competitive ability against neighboring plants. Invasive have repeatedly been shown drive that their adapt a wide range environmental suppress Using invasive as model species, discuss what currently known about generate productivity, ability, resilience. Specifically, potential enhanced through 1) positive direct feedback loops occur mutualistic associations; or 2) negative indirect loops, when affect heterospecific either allelopathy, disruption associations, increased pathogen abundance. Knowledge on exudate-microbe interactions may cropping system breeding superior genotypes, amendments disrupt weed-microbe interactions. We argue because native community often evolve response focusing efforts feedbacks, such those associations are likely lead long-term stress resilient crops. Future research should explore extent upregulating production specific exudates non-invasive species same responsible for success.

Organismal invasions have repeatedly been cited as a driving force behind the loss of biodiversity. Unlike many other impacts invasion, effect invasion on native symbiont communities has received less attention. The introduction invasive hosts presents potential opportunity to symbionts; could benefit symbionts through providing novel host environment that improves fitness relative their hosts. Alternatively, noncompetent for symbionts, resulting in negative abundance and diversity. Crayfish northern hemisphere diverse assemblages obligate annelid (P: Anellida, O: Branchiobdellida).

Abstract Although herbivory and allelopathy play important roles in plant invasions, their mediating the effect of diversity on invasion resistance remain unknown. In a 2‐year field experiment, we constructed native communities with four levels species richness (one, two, four, eight species) used factorial combination insecticide activated carbon applications to reduce allelopathy, respectively. We then invaded introduced Solidago canadensis L. One year after start there was no statistically significant net biomass invader. However, structural equation model showed that had positive direct invader partially balanced out by negative indirect via increased light interception. second year, relationship between when analyzed treatment separately. Therefore, conclude joint effects may major driving diversity–invasibility should be considered future studies.

The study aimed determine occurrence mycorrhizal and non-mycorrhizal herbs varied similarly or differently communities with different degrees A. dominance. analysed results 78 relevés carried out Belarusian Polesie, Middle Volga region Urals. In each region, dominance without it were described. status species determined using FungalRoot Database. It found, an increase probability arbuscular mycorrhiza formation, frequency those species’ registration decreased thickets. On contrary, status, increased Therefore, dominated negundo, selectively decreased.
