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 ...
An assessment of the information content of South African alien species databases
(AOSIS Publishing, 2015)
National alien species databases indicate the state of a country’s biodiversity and provide useful data for research on invasion biology and the management of invasions. In South Africa there are several different published ...
Forestry trial data can be used to evaluate climate-based species distribution models in predicting tree invasions
(Pensoft Publishers, 2014)
Climate is frequently used to predict the outcome of species introductions based on the results from species distribution models (SDMs). However, despite the widespread use of SDMs for pre- and post-border risk assessments, ...
How do invasive species travel to and through urban environments?
Globalisation has resulted in the movement of organisms outside their natural range, often with negative ecological and economic consequences. As cities are hubs of anthropogenic activities, with both highly transformed ...
Prioritising surveillance for alien organisms transported as stowaways on ships travelling to South Africa.
(Public Library of Science, 2017)
The global shipping network facilitates the transportation and introduction of marine and terrestrial organisms to regions where they are not native, and some of these organisms become invasive. South Africa was used as a ...
The Biogeography of South African Terrestrial Plant Invasions
Thousands of plant species have been introduced, intentionally and accidentally, to South Africa from many parts of the world. Alien plants are now conspicuous features of many South African landscapes and hundreds of ...
