Invasion debt – quantifying future biological invasions
(John Wiley & Sons Ltd, 2016)
Aim We develop a framework for quantifying invasions based on lagged trends in invasions (‘invasion debt’) with the aim of identifying appropriate metrics to quantify delayed responses at different invasion stages – from ...
Small urban centres as launching sites for plant invasions in natural areas: insights from South Africa
Alien species are often first introduced to urban areas, so it is unsurprising that towns and cities are often hotspots for invasions. However, while large cities are usually the first sites of introduction, small towns ...
Intentionally introduced terrestrial invertebrates: patterns, risks, and options for management
Our understanding and management of pathways of alien species introductions has improved significantly in the past few years. However, little attention has been paid in most parts of the world to the risks posed by the ...
Melaleuca parvistaminea Byrnes (Myrtaceae) in South Africa: Invasion risk and feasibility of eradication
We document and assess management options for the first reported invasion of Melaleuca parvistaminea Byrnes (initially identified asM. ericifolia) in the world, in the context of a South African wetland ecosystem. Delimitation ...
The global distribution of bamboos: assessing correlates of introduction and invasion
(Oxford University Press, 2017)
There is a long history of species being moved around the world by humans. These introduced species can provide substantial benefits, but they can also have undesirable consequences. We explore the importance of human ...
Framework and guidelines for implementing the proposed IUCN Environmental Impact Classification for Alien Taxa (EICAT)
(John Wiley & Sons Ltd, 2015)
Recently, Blackburn et al. (2014) developed a simple, objective and transparent method for classifying alien taxa in terms of the magnitude of their detrimental environmental impacts in recipient areas. Here, we present a ...
Biological invasions in the Cape Floristic Region: history, current patterns, impacts, and management challenges
(Oxford University Press, 2015)
The Cape Floristic Region (CFR) is the most invaded terrestrial area in South Africa in terms of: the conspicuous prominence of (mainly woody) invasive plants (Fig 12.1, Plate 12) (Henderson 2007); the area invaded as ...
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, ...
ABSTRACT: Reporting on the state of plant invasions in South Africa
(Elsevier B.V., 2017)
The (bio)diversity of science reflects the interests of society
For ecologists to develop robust generalizations and principles, a broad taxonomic and geographic spread of research is required, but, in practice, most generalizations are based on the research of individual scientists ...
