The extent and impacts of ungulate translocations: South Africa in a global context

Dian Spear, Auteur ; Steven L. Chown, Auteur

Dans Biological Conservation (142(2) FEB 2009)

Despite the apparent risks of the introduction of non-indigenous ungulates to biodiversity, relatively little is known globally about the pathways of introduction, propagule pressure and realized impacts of ungulate introductions. These issues w[...]

Human activities, propagule pressure and alien plants in the sub-Antarctic: Tests of generalities and evidence in support of management

Peter C. le Roux, Auteur ; Tshililo Ramaswiela, Auteur ; Jesse M. Kalwij, Auteur ; Justine D. Shaw, Auteur ; Peter G. Ryan, Auteur ; Anne M. Treasure, Auteur ; Gregory T. W. McClelland, Auteur ; Melodie A. McGeoch, Auteur ; Steven L. Chown, Auteur

Dans Biological Conservation (161 MAY 2013)

Despite concerns about the richness of plant invaders on islands, and their likely effects on local systems, impacts of these species seem to be small. However, this may be due to an absence of information on impacts, including changing species [...]
