For instance, the average Shannon index in selected bibliography was 2.67 and 1.90 in non-invaded and invaded sites, respectively (Vilà et al 2006;Andreu et al 2010;Novoa et al 2013;Fried et al 2014). Our study areas were relatively poorer but showed a similar trend, as Shannon index ranged between 1.25 and 2.03 in non- invaded areas, and between 0.82 and 1.25 in invaded ones (Table 3).…”

“…These changes, combined with shifts in microbial communities assemblage, make soils much more conducive to the establishment of the alien species and generally adverse for germination and/or growth of native species (de la Peña et al 2010;Conser and Connor 2009;Novoa et al 2013;. The intensity with which invasive alien species are capable of altering the physical and chemical characteristics of soils appears to be strongly dependent on the identity of the invaded habitat (Forey et al 2009;Maestre et al 2009;Santoro et al 2011;Fried et al 2014); however, time since invasion could be considerably important as it is recognized that impacts may change over time (Dostál et al 2013;Marchante et al 2015). Although the invasive process by Carpobrotus spp.…”

Background and aims Carpobrotus spp. are amongst the most impactful and widespread plant invaders of\ud Mediterranean habitats. Despite the negative ecological impacts on soil and vegetation that have been documented,\ud information is still limited about the effect by Carpobrotus on soil microbial communities. We aimed\ud to assess the changes in the floristic, soil and microbial parameters following the invasion by Carpobrotus cfr.\ud acinaciformis within an insular Mediterranean ecosystem.\ud Methods Within three study areas a paired-site approach, comparing an invaded vs. a non-invaded plot, was\ud established. Within each plot biodiversity indexes, C and N soil content, pH and microbial biomass and structure\ud (bacterial and fungal) were assessed.\ud Results Invaded plots showed a decrease of α-species richness and diversity. The least represented plant species\ud in invaded plots were those related to grassland habitats. In all invaded soils, a significant increase of carbon and\ud nitrogen content and a significant decrease of pH were registered. Carpobrotus significantly increased bacterial\ud and fungal biomass and altered soil microbial structure, particularly favoring fungal growth.\ud Conclusions Carpobrotus may deeply impact edaphic properties and microbial communities and, in turn, these\ud strong modifications probably increase its invasive potential and its ability to overcome native species, by preventing their natural regeneration

“…Recent work tends to focus on the competitive effects of invasive species to answer important questions regarding how they impact the communities they invade (Fried et al 2014). However, competitive response allows one to investigate the ability of exotic species to invade a novel environment with native plant competitors.…”

Genetic lineages of the invasive Aegilops triuncialis differ in competitive response to neighboring grassland species

Competitive dynamics between native and exotic species can influence both the success of exotics in the novel environment as well as diversity and abundance of native species. Invasive species are often characterized by multiple introductions in the novel range, which can lead to population differentiation for invasion characteristics. Here we use two invasive lineages of the exotic grass, Aegilops triuncialis L., to determine if these lineages differ in their response to competitors and in their persistence in the invaded range. We find that one lineage is negatively affected by competitor presence in both flowering phenology and reproductive output, while the other lineage shows no response in either trait. Furthermore, we find that the two lineages were introduced at different times and are each capable of replacing the other as the most abundant lineage of a given county. Our results demonstrate that genetic lineage is a more important determinant of competitive response than neighbor identity, and that the two lineages may employ alternate invasion mechanisms. Because management techniques are decided upon based on traits that confer invasiveness, our results highlight the importance of considering intraspecific variation in the invaded range.
