Road verges as invasion corridors? A spatial hierarchical test in an arid ecosystem
Disturbed habitats are often swiftly colonized by alien plant species. Human inhabited areas may act as sources from which such aliens disperse, while road verges have been suggested as corridors facilitating their dispersal. ...
Invasive alien plants infiltrate bird-mediated shrub nucleation processes in arid savanna
1 The cultivation and dissemination of alien ornamental plants increases their potential to invade. More specifically, species with bird-dispersed seeds can potentially infiltrate natural nucleation processes in ...
Residence time and potential range: crucial considerations in modelling plant invasions
A prime aim of invasion biology is to predict which species will become invasive, but retrospective analyses have so far failed to develop robust generalizations. This is because many biological, environmental, and ...
Worldwide spread of the Argentine ant, Linepithema humile (Hymenoptera: Formicidae)
(Austrian Society of Entomofaunistics, 2009)
The Argentine ant, Linepithema humile (MAYR, 1868), originally from subtropical South America, is an important pest in many parts of the world. To evaluate its worldwide distribution and potential for further spread, we ...
