“…There are many examples of biotic interactions affecting performance through differences in pathogen (Dodds & Rathjen 2010) and browsing susceptibility (Fornara & Du Toit 2008;Moncrieff et al 2014) as well as mutualism (Cromsigt & Kuijper 2011). Most plant examples of interspecific interactions affecting genotype performance or fitness at the same trophic level have focused on annual plants (File et al 2012;Nierbauer et al 2016), specifically in the context of the evolution of increased competitive ability (Puritty et al 2018) with only a few studies on trees (Hirsch et al 2016;Grady et al 2017;Siemann et al 2017). Interspecific interactions may impact genotype (e.g.…”

The stability of species and provenance performance across diverse environments is a major issue in restoration, particularly for assisted migration and climate‐adjusted provenancing strategies. This study examines how differences in species and provenance performance are affected by plant community composition in a dry sclerophyll forest restoration experiment. Five indices were measured over 6 years post‐establishment to evaluate the relative performance of community composition using 10 provenances of two focal eucalypts (Eucalyptus pauciflora and Eucalyptus tenuiramis) under six community treatments for E. pauciflora and five for E. tenuiramis. Community treatments varied according to the species planted as the immediate neighbor to the focal species, and included same species, same genus, or one of three different genera. Significant species and provenance differences were observed for all measured performance indices, with no evidence of interaction effects with community treatments. E. tenuiramis was more susceptible to insects and frost, and had poorer establishment but greater growth of the survivors than E. pauciflora. Generally, nonlocal provenances were more susceptible to insect herbivory and frost damage and had higher mortality than local provenances. At this early life‐stage there was no evidence that co‐planted species affected the relative performance of focal species or provenances, arguing transfer functions are likely stable across different planted communities. While species and provenance performance was not affected by community context, focal species differed in their response to upslope migration and any climate‐adjusted provenancing may require staged transfers to avoid maladaptation under contemporary growing conditions.

“…The high germination potential, abundant seed production and high dispersal capacity by wind or animals of both species could favor their establishment in disturbed zones [74][75][76]. Both species have been registered as invasive in other regions of the world [74,77], having an important impact on native communities. For example, B. tectorum alters the nutrient cycle, water availability and fire frequency, and may exclude native species [74].…”

Alien plant species on roadsides of the northwestern Patagonian steppe (Argentina)

The introduction of alien species represents one of the greatest threats to biodiversity worldwide. Highway construction increases the dispersal and invasion of exotic plant species. This study examined the assembly process of the plant communities to determine whether the roadsides of the Patagonian steppe represent a reservoir and dispersal source of invasive exotic species. We analyzed the composition of exotic and native species and functional groups present in the established vegetation and seed banks of roadsides and reference areas nearby. The type of dispersal of exotic and native species at the roadsides was also evaluated. Total cover and that of exotic and native species was lower at the roadsides than in the reference areas; however, at the roadsides the cover and seed abundance of exotic species was higher than that of native species. In the roadsides vegetation, native shrubs such as Acaena splendens predominated, along with exotic perennial herbs and grasses which were mainly represented by Rumex acetosella. In the seed bank the predominant species were exotic perennial herbs, also represented by R. acetosella, annual exotic species such as Epilobium brachycarpum and Verbascum thapsus, and annual native species such as Heliotropium paronychioides. No exotic shrubs were found either at the roadsides or in the reference areas. The species at the roadsides did not present a dominant type of dispersal. The abundance of exotic species at the roadsides, both in the aboveground vegetation and the seed bank, may be due to the stressful environment and the characteristics of the species themselves, such as the ability to form seed banks. This work revealed that the roadsides of the Patagonian steppe constitute reservoirs of invasive exotic species, highlighting the importance of identifying them and controlling their spread, with a view to generating ecosystem management programs.

“…As Gregor et al (2013) point out, the species shows great expansive potential in Europe favored by the genetic diversity of the populations, sourced from at least one triple introduction (Nierbauer et al 2016). The European EOO -excluded the Iberian Peninsula-cover a surface area of c. 980,000 km 2 with the species being present in six countries; France, Germany, Belgium, Italy, the Czech Republic and Great Britain (see Fig.…”
