A standardized set of metrics to assess and monitor tree invasions
Scientists, managers, and policy-makers need functional and effective metrics to improve our understanding and management of biological invasions. Such metrics would help to assess progress towards management goals, ...
Understanding and managing the introduction pathways of alien taxa: South Africa as a case study
For the effective prevention of biological invasions, the pathways responsible for introductions must be understood and managed. However introduction pathways, particularly for developing nations, have been understudied. ...
A simple, rapid methodology for developing invasive species watch lists
Biosecurity schemes aim to prevent the introduction of species with a high invasion potential, without unduly restricting personal freedom and commercial activities. But invasive species risk assessments are time consuming, ...
Introduced and invasive cactus species: a global review
(Oxford University Press, 2015)
Understanding which species are introduced and become invasive, and why, are central questions in invasion science. Comparative studies on model taxa have provided important insights, but much more needs to be done to ...
The balance of trade in alien species between South Africa and the rest of Africa
Background: Alien organisms are not only introduced from one biogeographical region to another but also spread within regions. As South Africa shares land borders with six countries, multiple opportunities exist for the ...
The threats posed by the pet trade in alien terrestrial invertebrates in South Africa
The pet trade has been a major pathway for the introduction of vertebrate invaders, but little is known about its role in invertebrate invasions. Here we assess the trade in terrestrial invertebrates (excluding spiders) ...
