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

Founding events in species invasions: genetic variation, adaptive evolution, and the role of multiple introductions
TL;DR: It is concluded that management limiting gene flow among introduced populations may reduce adaptive potential but is unlikely to prevent expansion or the evolution of novel invasive behaviour.

Alien plants in checklists and floras: towards better communication between taxonomists and ecologists

TL;DR: Recommendations are outlined on how to deal with the issue of plant invasions in standard floras with the aim of contributing to a better understanding between taxonomists and ecologists and allowing more detailed comparative analyses of alien floras of various regions of the world.

Ecological and evolutionary consequences of biotic homogenization.
TL;DR: The goal is to initiate future research that investigates the broader conservation implications of homogenization and to promote a proactive style of adaptive management that engages the human component of the anthropogenic blender that is currently mixing the biota on Earth.
Journal ArticleDOI
Jack of all trades, master of some? On the role of phenotypic plasticity in plant invasions
TL;DR: What is required to assess phenotypic plasticity at different levels is described and a new framework can be applied when testing both ecological or evolutionary oriented hypotheses, and therefore promises to bridge the gap between the two perspectives.

TL;DR: The database is designed as a practical database for taxonomists, plant geographers, ecologists, conservationists, and teachers, as well as for amateur botanists and plant hunters as discussed by the authors.

TL;DR: One of the most popular books now is the flowering plants evolution above the species level as discussed by the authors, but it is difficult to find the book in the book store around the city. And when you have found the store to buy the book, it will be so hurt when you run out of it.

Transgressive segregation, adaptation and speciation
TL;DR: Credence is lent to the view that hybridization may provide the raw material for rapid adaptation and provide a simple explanation for niche divergence and phenotypic novelty often associated with hybrid lineages.
