Alien invaders and reptile traders: risk assessment and modelling of trends, vectors and traits influencing introduction and establishment of alien reptiles and amphibians
Biological invasions are a growing threat to biodiversity, trade and agriculture in South Africa. Though alien reptiles and amphibians (herpetofauna or herps) are not currently a major threat, escalating problems worldwide ...
Why Carcinus maenas cannot get a grip on South Africa’s wave-exposed coastline
(NISC Pty Ltd, 2007)
The European green crab Carcinus maenas has established considerable breeding populations in harbours and sheltered bays in the South-Western Cape, South Africa, but appears unable to flourish on the waveexposed coastline. ...
Assessing the invasiveness of Acacia stricta and Acacia implexa: is eradication an option?
This thesis investigates the invasiveness and current status of two Acacia species recently identified as invaders in South Africa in order to determine the feasibility of their eradication. Australian acacias are among ...
Patterns and processes of alien plant invasions in small urban areas in South Africa: The Berg River Catchment as a case study (ALL TOWNS)
Dataset of all identified alien plant species from 11 small towns in the Berg River catchment. In each town, a selection of roads were sampled for all alien plant species.
Climate change and invasion impacts in the sub-Antarctic
Climate change and biological invasions are major threats to biodiversity. In particular, these threats are predicted to influence terrestrial systems in the sub-Antarctic, where significant ecosystem responses to both ...
Determining the invasive status of Australian Acacia species in South Africa, and the potential for eradicating species with limited distributions
While widespread invasions of Australian acacia species (wattles) have been fairly well documented, very little is known about species that have no substantial commercial value or those that are not well-established invaders ...
A review of five vertebrate invaders in South Africa
Invasive alien species are listed as one of three major threats to global biodiversity. They can be detrimental through affecting the function and structure of ecosystems and degrading human health. Five vertebrate species ...
Hull fouling as primary mechanism for the potential transport of non-indigenous species to Antarctica, Marion- and Gough Island
Marine non-indigenous species (NIS) introductions are becoming more evident and marine ecosystems are threatened by this phenomenon. There are two main ship-based mechanisms for the transport of marine NIS, namely discharge ...
