Researchers from the DSI/NRF Centre for Invasion Biology at Stellenbosch University have found that, scarcely a hundred years after Guttural Toads were introduced to the islands of Mauritius and Réunion, their overall body size has been reduced by up to a third compared to their counterparts in South Africa.
Researchers at the Centre for Invasion Biology (C·I·B) at Stellenbosch University, found that the introduction histories of the globally important invasive tree Silver wattle (Acacia dealbata) are complex and cannot be generalized.
The brown rat (Rattus norvegicus) and the house mouse (Mus musculus) are some of the world’s worst invasive rodent species. They are known to spread zoonotic diseases, damage crops and household items, outcompete native species for food, and prey on some bird species.
An intensive biodiversity assessment in the Kruger National Park, South Africa, recorded 20 naturalised alien plant species, of which only four had previously been recognized as invasive, and one species represented a new introduction for the park.
The lesser of two weevils? How insect thermal traits can help to understand biocontrol success and failure
Water hyacinth (Eichhornia crassipes) is a widespread invasive species impacting a range of ecosystem services in South Africa, especially water quality and availability. To better control this aquatic weed, several biocontrol agents have been released – unfortunately with mixed success.
