Non-native invasive species (NIS) release chemicals into the environment that are unique to the invaded communities, defined as novel chemicals. Novel chemicals impact competitors, soil microbial communities, mutualists, plant enemies, and soil nutrients differently than in the species' native range. Ecological functions of novel chemicals and differences in functions between the native and non-native ranges of NIS are of immense interest to ecologists. Novel chemicals can mediate different ecological, physiological, and evolutionary mechanisms underlying invasion hypotheses. Interactions amongst the NIS and resident species including competitors, soil microbes, and plant enemies, as well as abiotic factors in the invaded community are linked to novel chemicals. However, we poorly understand how these interactions might enhance NIS performance. New empirical data and analyses of how novel chemicals act in the invaded community will fill major gaps in our understanding of the chemistry of biological invasions. A novel chemical-invasion mechanism framework shows how novel chemicals engender invasion mechanisms beyond plant-plant or plantmicroorganism interactions.

“…Solidago gigantea is a rhizomatous perennial herb that is native to North America but has become highly invasive throughout Europe and Asia (Weber & Jakobs 2005). In its non-native range, it exerts a negative impact on native communities by decreasing species richness and diversity, apparently due to its intense competitive effects (Botta-Duk at & Dancza 2012; Pal et al 2015;Lucero et al 2020), rapid growth (Jakobs et al 2004), and its positive interactions with resident soil biota (Majewska et al 2017). It is challenging to control in its non-native ranges because of its tolerance to a variety of biotic and abiotic stressors (Shibel & Heard 2016) and its rapid vegetative propagation (Nagy et al 2018).…”

Interactions among native and invasive species may affect management outcomes and goals. We implemented different mowing regimes to control the invasive Solidago gigantea and restore natural diversity, and also examined interactions between Solidago and a European native competitor, Tanacetum vulgare in the context of these regimes. Experimentally planted Tanacetum suppressed Solidago by 79% without management, and a suite of mowing management regimes reduced the density of Solidago by 80-98% when Tanacetum was absent. But, when Tanacetum was added, the density of the invader was not reduced by mowing. Put another way, in mowed plots with Tanacetum, Solidago was twofold to over fivefold denser than in mowed plots without Tanacetum. It is not clear why the effect of Tanacetum shifted from competition in the absence of disturbance to facilitation with intense management-associated disturbance, but other studies suggest that Tanacetum may create plant-soil feedbacks that favor Solidago. Evidence shows similar shifts from competition to facilitation under mowing regimes for other species, but these are not mechanistically clear either. We speculate that mowing reduced competition from Tanacetum while leaving belowground facilitative effects unchanged, shifting the net effect of Tanacetum to facilitation. When single-year mowed plots were abandoned for just 1 year, Solidago was twofold denser than in the control, thus maintaining treatments over time was important for successful management. Our results indicate that mechanical control may substantially alter biotic resistance gained from native competition.

“…Structures of mycorrhizal networks depend on the composition of plant species in a given area (Chagnon et al, 2019). The formation of mycorrhizal network was demonstrated for Tanacetum vulgare, S. canadensis, and Cichorium intybus (Awaydul et al, 2018;Lucero et al, 2020).…”

“…Competitiveness of invasive and native plants can be influenced by CMN, which simultaneously colonize root systems of several plants, affecting ecosystem processes and dynamics of plant communities (Selosse et al, 2006;Horton, van der Heijden, 2008;van der Heijden, Horton, 2009;Horton, 2015). A necessary condition for the formation and functioning of a mycorrhizal network is the ability of neighboring plants to be colonized by CMN (Lucero et al, 2020). Structures of mycorrhizal networks depend on the composition of plant species in a given area (Chagnon et al, 2019).…”

“…Branches corresponding to partitions reproduced in less than 40 % bootstrap replicates are collapsed by a change in the growth rate of roots and shoots, in the processes of photosynthesis and nutrition, and in the plant defense reactions. It was shown that Tanacetum vulgare in association with Solidago canadensis was less attacked by insects and tolerated losses of biomass to a greater extent than the association-free plants (Lucero et al, 2020). The process of CMN development by an invasive plant can affect plant communities, including intra-and interspecific interactions, species coexistence, and biodiversity.…”

Does arbuscular mycorrhiza favor invasion of some Asteraceae tribes?

2021

View full text Add to dashboard Cite

Invasive species, including more than three dozen Asteraceae, such as Solidago canadensis, Leucanthemum vulgare, Senecio inaequidens etc, pose serious threat to ecosystem health. Arbuscular mycorrhizal symbiosis is a key factor for distribution of invasive species of some Asteraceae tribes, including Astereae, Anthemideae, Senecioneae, Gnaphalieae, Cardueae, and Cichorieae. The formation of invasion-friendly plant communities has occurred through increasing nutrient and water availability, hormonal regulation, production of bioactive compounds, and mycorrhiza-induced resistance of host plants. Native species are displaced through the influence on soil microbiota, mycorrhizal and nutrient status of neighboring plants, and several other parameters. Allelopathic influences and symbiotic interactions with bacteria and other fungi can inhibit these processes. Understanding the mycorrhizal status of invasive weeds, in our opinion, is a necessary condition for their successful control.
