The North American historic phytogeographic distribution of mugwort (Artemisia vulgaris) and Japanese knotweed (Polygonum cuspidatum), two invasive perennial species introduced from Eurasia and East Asia respectively, was recreated using herbarium records. The putative initial introduction of these two species differs by c.a. 400 years, but their patterns of geographic distribution, introduction pathways, and local dispersal pathways are similar. Both species showed the expected logistic growth… 

The biology of invasive alien plants in Canada. 5. Polygonum cuspidatum Sieb. & Zucc. [=Fallopia japonica (Houtt.) Ronse Decr.].

The phytogeographic distribution of P. cuspidatum in North America suggests a large number of intentional introductions via ornamental plantings from 1870 to 2000, followed by secondary spread from these foci, and the primary means of local and regional range expansion is human-mediated transport of rhizome-infested soil.

Knotweed (Fallopia spp.) Invasion of North America Utilizes Hybridization, Epigenetics, Seed Dispersal (Unexpectedly), and an Arsenal of Physiological Tactics

It is observed that knotweed species clearly possess 8 of the 12 ideal weed characteristics, with Bohemian knotweed likely exhibiting still more because of prolific seed production, and only a thoroughly researched, well-informed approach to knotweed management across North America can be successful.

Revealing Historic Invasion Patterns and Potential Invasion Sites for Two Non-Native Plant Species

Despite differences in initial introduction loci and pathways, Japanese knotweed and mugwort demonstrate similar historic patterns of spread and show declining rates of regional expansion, suggesting these perennials are reaching the limits of large-scale expansion.


Herbarium records were studied to infer the introduction history and spread of the exotic Eurasian sickleweed (Falcaria vulgaris Bernh.) in the United States. The spread of the plant was

Observations of extended lag phase of nonnative invasive Frangula alnus (Rhamnaceae) may be spatial-scale dependent1

Examining the spread of this species at the continental scale, it appears to have experienced an extended lag phase early in its invasion history, but has steadily increased in area of occupancy since ca.

Sexual reproduction of Japanese knotweed (Fallopia japonica s.l.) at its northern distribution limit: new evidence of the effect of climate warming on an invasive species.

The effect of climate change is already palpable on the phenology of invasive plant species at their northern distribution limit, and Bohemian knotweed, which until recently was rare in Quebec, could rapidly spread in the near future with the help of an additional diaspore type (seeds).

Spatiotemporal Analysis of Three Common Wetland Invasive Plant Species Using Herbarium Specimens and Geographic Information Systems

The use of two different methods and the subsequent comparison of results show the importance of sampling bias correction, scale selection, and adequate sample sizes for spatiotemporal analyses of plant distributions using herbarium records.

Using the nuclear LEAFY gene to reconstruct phylogenetic relationships among invasive knotweed (Reynoutria, Polygonaceae) populations

The widespread existence of hybrid plants in Wisconsin, many of which are morphologically identifiable as R. japonica and R. sachalinensis, indicates a cryptic genetic diversity that should be examined more broadly in North America using molecular tools.



Red brome (Bromus rubens subsp. madritensis) in North America: possible modes for early introductions, subsequent spread

The results challenge the most frequently cited sources describing the early history of this grass and suggest three possible modes for early introductions: the California Gold Rush and Central Valley wheat, southern California shipping, and northern California sheep.

The distribution and history in the British Isles of some alien species of Polygonum and Reynoutria

An account is given of the escape from garden cultivation of four members of the Polygonaceae introduced from Eastern Asia: Reynoutriajaponica Houtt., including the dwarfvar. compacta (Hooker fil.)

The dynamics of plant invasions: a case study of three exotic goldenrod species (Solidago L.) in Europe

The data suggest that S. altissima and S. gigantea will successfully spread further, leading to an increase in abundance and area, while S. graminifolia seems to spread slowly.

The distribution in bankside habitats of three alien invasive plants in the U.K. in relation to the development of control strategies

The national distribution of Fallopia japonica (Japanese Knotweed), Heracleum mantegazzianum (Giant Hogweed) and Impatiens glandulifera (Himalayan Balsam) in bankside habitats is given for 1994-96 in

The expansion history of a sexual and asexual species of Cortaderia in California, USA

The expansion histories of two South American species of Cortaderia, similar in morphology but differing profoundly in their breeding systems, were compared in California, USA, finding that sexual C.selloana has expanded spatially at twice the rate of the asexual C.jubata.

Differences in invasibility of two contrasting habitats and invasiveness of two mugwort Artemisia vulgaris populations

It is demonstrated that variation exists in habitat invasibility, and that intraspecific variation in growth patterns occurs in mugwort, and the interaction between habitat traits and species characteristics was found to be important when determining invasion success.

Distribution of Exotic Plants along Roads in a Peninsular Nature Reserve

The results add support to the idea that roads act as disturbances that promote invasive species, but not to the concept that roads acts as corridors for the flow of invasive propagules into new landscapes.

The use of molecular markers to study patterns of genotypic diversity in some invasive alien Fallopia spp. (Polygonaceae)

A comparison of RAPDs and inter‐SSRs showed that the two techniques gave data that are broadly congruent, and both techniques showed a similar sensitivity in the number of genotypes detected.

Sexual reproduction in the invasive species Fallopia japonica (Polygonaceae).

That sexual reproduction and seedling survival occur in the wild has strong implications for the development of management strategies for this species.
