(e.g. frequency, timing, types, etc.), attractiveness to humans, and physiological performance can all contribute to a species’ ability to successfully invade (Rejmanek and Richardson 1996, Pyšek and Richardson 2007, van Kleunen et al. 2010, Sol et al. 2012). Field-based investigations ranging from the plot to the global level have further revealed that the functional distinctness of non-native...

The impact of a biological invasion on native communities is expected to be uneven across invaded landscapes due differences in local abiotic conditions, invader abundance, and traits composition the community. One way improve predictive ability about an invasive species given variable conditions exploit known mechanisms driving species' success. Invasive plants frequently exhibit allelopathic ...

Biological invaders have long been hypothesized to exhibit the fast end of the life-history spectrum, with early reproduction and a short lifespan. Here, we examine the rapid evolution of life history within the harlequin ladybird Harmonia axyridis. The species, once used as a biological control agent, is now a worldwide invader. We show that biocontrol populations have evolved a classic fast l...

The novel weapons hypothesis posits that biochemical compounds secreted by an invasive species facilitate its success by reducing the performance and survival of other species. This mechanism has been proposed to explain the widespread invasion of the biennial plant, Alliaria petiolata, in North America. Root exudates produced by A. petiolata, a nonmycorrhizal plant, suppress the growth of myco...

The Asian clam of the genus Corbicula is most successful freshwater invader worldwide. In this research note, presence largillierti recorded for first time in Lower São Francisco River. This record based on collection living organisms from Xingó Hydroelectric Power Plant reservoir. second corbiculid species region. Further investigation required characteristics such as its distribution, interac...

This study was carried out at the meadows and pastures in Çolpan village of Van province 2020. In study, matter yield, botanical composition, plant covered area, rate decreaser/increaser/invader species were determined. The Loop method used to determine composition. grassland area identified 69 belonging 17 families. meadow 20 6 amount Poaceae, Fabaceae other families found determined as 18.66...

Anthropogenic removal of natural dispersal barriers and modification of natural habitats have contributed to the spread of non-native species. Potential invaders that are cryptic in appearance and/or behaviour are particularly troublesome as this confounds efforts to detect or manage incipient invasions. Here we report one such invader, the Florida serrate crownsnail, Pyrgophorus platyrachis Th...

Biological invasions are a major threat to biodiversity; however, the degree of impact can vary depending on the ecosystem and taxa. Here, we test whether a top invader at a global scale, the tree Robinia pseudoacacia (black locust or false acacia), which is known to profoundly change site conditions, significantly affects urban animal diversity. As a first multi-taxon study of this kind, we an...

BACKGROUND To understand the processes of invasions by alien insects is a pre-requisite for improving management. The whitefly Bemisia tabaci is a cryptic species complex that contains some of the most invasive pests worldwide. However, extensive field data to show the geographic distribution of the members of this species complex as well as the invasion by some of its members are scarce. MET...
