TLDR
This model does not represent the only evolutionary pathway to invasiveness, but is clearly an underappreciated mechanism worthy of more consideration in explaining the evolution ofinvasiveness in plants.Abstract:
Invasive species are of great interest to evolutionary biologists and ecologists because they represent historical examples of dramatic evolutionary and ecological change. Likewise, they are increasingly important economically and environmentally as pests. Obtaining generalizations about the tiny fraction of immigrant taxa that become successful invaders has been frustrated by two enigmatic phenomena. Many of those species that become successful only do so (i) after an unusually long lag time after initial arrival, and/or (ii) after multiple introductions. We propose an evolutionary mechanism that may account for these observations. Hybridization between species or between disparate source populations may serve as a stimulus for the evolution of invasiveness. We present and review a remarkable number of cases in which hybridization preceded the emergence of successful invasive populations. Progeny with a history of hybridization may enjoy one or more potential genetic benefits relative to their progenitors. The observed lag times and multiple introductions that seem a prerequisite for certain species to evolve invasiveness may be a correlate of the time necessary for previously isolated populations to come into contact and for hybridization to occur. Our examples demonstrate that invasiveness can evolve. Our model does not represent the only evolutionary pathway to invasiveness, but is clearly an underappreciated mechanism worthy of more consideration in explaining the evolution of invasiveness in plants.read more

Assessment of Solidago × niederederi Origin Based on the Accumulation of Phenolic Compounds in Plant Raw Materials
TL;DR: In this article, the authors provided the first phytochemical characterization of the morphologically identified natural hybrid Solidago × niederederi Khek compared with the native Solidago virgaurea and two invasive species, Canada goldenrod (Solidago canadensis L.) and giant goldenrod(Solidago gigantea Aiton).

Genetic traits leading to invasion: plasticity in cold hardiness explains current distribution of an invasive agricultural pest, Tetranychus evansi (Acari: Tetranychidae)
TL;DR: Mites belonging to the widespread lineage 1 exhibit increased cold tolerance suggesting broader adaptability, helping to explain T. evansi's current geographical distribution.

Invasive Fallopia × Bohemica Interspecific Hybrids Display Different Patterns in Secondary Metabolites
Florence Piola,Floriant Bellvert,Guillaume Meiffren,Soraya Rouifed,Vincent Walker,Gilles Comte,Cédric Bertrand +6 more
TL;DR: The results suggest an evolution in the chemical traits of Fallopia taxa in invaded areas such that certain genotypes may well have acquired new chemical cocktails resulting from post-introduction hybridizations.

Gene flow in Prunus species in the context of novel trait risk assessment
TL;DR: The results of this review suggest that the commercialization of one GM Prunus species can create coexistence issues for commercial non-GM Prinus production and serve as a resource for environmental risk assessment related to pollen mediated gene flow and the release of transgenicPrunus.

Environmental and Economic Costs of Nonindigenous Species in the United States
TL;DR: Aproximately 50,000 nonindigenous (non-native) species are estimated to have been introduced to the United States, many of which are beneficial but have caused major economic losses in agriculture, forestry, and several other segments of the US economy, in addition to harming the environment.
