Predation-driven biotic resistance fails to restrict the spread of a sessile rocky shore invader
(Inter Research, 2015-03-02)
The invasive barnacle Balanus glandula has progressively spread along the South African west coast. We used multiple approaches to assess the role of predation by indigenous whelks in regulating this expansion. B. glandula ...
The importance of pollinators and autonomous self-fertilisation in the early stages of plant invasions: Banksia and Hakea (Proteaceae) as case studies
(German Botanical Society and the Royal Botanical Society of the Netherlands, 2016)
Reproduction is a crucial stage in the naturalisation of introduced plant species. Here, using breeding system experiments and observations of floral visitors, we investigate whether a lack of pollinators or an inability ...
Managing invasive species in cities: a decision support framework applied to Cape Town
It has been suggested that existing frameworks for guiding management of invasive species in rural areas and protected areas are inadequate for dealing with invasions in urban settings. A framework for selecting appropriate ...
Assessing and managing the threat posed by Epipremnum aureum in South Africa
(Elsevier B.V., 2017)
The predictive success of risk assessments is still largely a function of invasiveness elsewhere. Therefore, species that are invasive elsewhere should be prioritised for management, and where possible eradicated. We set ...
A new national unit for invasive species detection, assessment and eradication planning
(Academy of Science of South Africa, 2013)
Even with no new introductions, the number of biological invasions in South Africa will increase as introduced species naturalise and become invasive. As of 2010 South Africa had ~8750 introduced plant taxa, 660 recorded ...
Alien bamboos in South Africa: a socio-historical perspective
Changes in fashions and economic imperatives underlying plant introductions have a profound influence on the movement of species around the world. Using bamboo introductions into South Africa as a case-study, we explore ...
