We report the development of rootless plantlets in inflorescences of Pennisetum setaceum (Fountain grass) invasive in the Gamka River in the Karoo National Park, South Africa. The pseudo-vivipary appeared to have been ...

Road verges as invasion corridors? A spatial hierarchical test in an arid ecosystem

Kalwij, Jesse Machiel Jr; Milton, Suzanne J.; McGeoch, Melodie A. (Springer, 2008-02-14)

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. ...

Superiority in competition for light: A crucial attribute defining the impact of the invasive alien tree Schinus molle (Anacardiaceae) in South African savanna

Iponga, D.M.; Milton, S.J.; Richardson, D.M. (Elsevier Ltd., 2008)

Invasion of ecosystems by woody alien plant species is a widespread phenomenon. Interspecific competition has often been suggested as a mechanism for replacement of one species by another, but this is rarely tested. We ...

Iponga, D.M.; Cuda, J.P.; Milton, S.J.; Richardson, D.M. (The Entomological Society of Southern Africa, 2008)
