“…As the number of invasive species continues to increase internationally, the interaction of multiple coexisting invaders is of growing importance (Jackson 2015) and has been hypothesised as potentially leading to an 'invasional meltdown' (Simberloff and Von Holle 1999). This meltdown implies a positive feedback and additive effect amongst invasions over time, especially when the invaders are from the same region (Ricciardi 2001;Simberloff 2006).…”

“…Once at a N-rich site, exotic species can exploit N more quickly than later successional natives by increasing growth rates in response to higher nutrient availability (Carson and Barrett 1988;Fogarty and Facelli 1999). Nitrogen enrichment by exotic N-fixing species can facilitate the further invasion by other exotic species (Adler et al 1998;Carino and Daehler 2002;Maron and Jefferies 1999;Sher and Hyatt 1999), moving the system toward an ''invasional meltdown'' (Simberloff 2006;Simberloff and Von Holle 1999).…”

This study examines the impact of the exotic nitrogen-fixing legume Melilotus officinalis (L.) Lam. on native and exotic species cover in two Great Plains ecosystems in Badlands National Park, South Dakota. Melilotus is still widely planted and its effects on native ecosystems are not well studied. Melilotus could have direct effects on native plants, such as through competition or facilitation. Alternatively, Melilotus may have indirect effects on natives, e.g., by favoring exotic species which in turn have a negative effect on native species. This study examined these interactions across a 4-year period in two contrasting vegetation types: Badlands sparse vegetation and western wheatgrass (Pascopyrum smithii) mixed-grass prairie. Structural equation models were used to analyze the pathways through which Melilotus, native species, and other exotic species interact over a series of 2-year time steps. Melilotus can affect native and exotic species both in the current year and in the years after its death (a lag effect). A lag effect is possible because the death of a Melilotus plant can leave an open, potentially nitrogen-enriched site on the landscape. The results showed that the relationship between Melilotus and native and exotic species varied depending on the habitat and the year. In Badlands sparse vegetation, there was a consistent, strong, and positive relationship between Melilotus cover and native and exotic species cover suggesting that Melilotus is acting as a nurse plant and facilitating the growth of other species. In contrast, in western wheatgrass prairie, Melilotus was acting as a weak competitor and had no consistent effect on other species. In both habitats, there was little evidence for a direct lag effect of Melilotus on other species. Together, these results suggest both facilitative and competitive roles for Melilotus, depending on the vegetation type it invades.

“…The spread and success of exotic species may be facilitated by (i) climate change (4), (ii) increase in disturbed and͞or anthropogenic habitats (5,6), and (iii) synergistic effects resulting from increased biotic exchanges (7,8). In turn, biological invasions may feed back into global change (9) by modifying interactions among species and even whole ecosystems (10,11), inducing extinction in the native fauna͞flora (12,13) and homogenizing global diversity (14,15).…”

Worldwide marine invaders, such as the brown alga Undaria pinnatifida, offer challenging models for unraveling the apparent paradox of sustainable settlement of exotic species over a large spectrum of environments. Two intergenic noncoding mitochondrial loci were found to be highly informative at the within-species level. Twenty-five haplotypes were found over the whole dataset (333 base pairs, 524 individuals, and 24 populations). The native range showed striking population genetic structure stemming from low diversity within and high differentiation among populations, a pattern not observed in the introduced range of this seaweed. Contrary to classical expectations of founding effects associated with accidental introduction of exotic species, most of the introduced populations showed high genetic diversity. At the regional scale, genetic diversity and sequence divergence showed contrasting patterns in the two main areas of introduction (Europe and Australasia), suggesting different processes of introduction in the two regions. Gene genealogy analyses point to aquaculture as a major vector of introduction and spread in Europe but implicate maritime traffic in promoting recurrent migration events from the native range to Australasia. The multiplicity of processes and genetic signatures associated with the successful invasion confirms that multiple facets of global change, e.g., aquaculture practices, alteration of habitats, and increased traffic, act in synergy at the worldwide level, facilitating successful pandemic introductions.coastal habitats ͉ gene genealogy ͉ introduced species ͉ kelp ͉ mitochondrial DNA
