Advancing impact prediction and hypothesis testing in invasion ecology using a comparative functional response approach
Invasion ecology urgently requires predictive methodologies that can forecast the ecological impacts of existing, emerging and potential invasive species. We argue that many ecologically damaging invaders are characterised ...
Analysis of active rotenone concentration during treatment of the Rondegat River, Cape Floristic Region, South Africa: evaluation of the Minimum Effective Dose (MED).
(NISC/ Taylor and Francis, 2014)
Most endemic freshwater fish species of the Cape Floristic Region are listed as threatened, due mainly to the impacts of invasive alien fish species. The piscicide rotenone has been identified as a potential tool to aid ...
Are African longfin eel imports a potential pathway for parasite invasions?
Tackling invasive alien species in Europe: the top 20 issues
Globally, Invasive Alien Species (IAS) are considered to be one of the major threats to native biodiversity, with the World Conservation Union (IUCN) citing their impacts as ‘immense, insidious, and usually irreversible’. ...
Existing and emerging high impact invasive species are characterized by higher functional responses than natives.
(Royal Society Publishing, 2014)
Predicting ecological impacts of invasive species and identifying potentially damaging future invaders are research priorities. Since damage by invaders is characterized by their depletion of resources, comparisons of the ...
A review of current knowledge, risk and ecological impacts associated with non-native freshwater fish introductions in South Africa.
The introduction and spread of non-native species is one of the least reversible human-induced global changes. In South Africa, non-native fish introductions have occurred over the last two and a half centuries. Resultant ...
Threatened endemic fishes in South Africa’s Cape Floristic Region: a new beginning for the Rondegat river
(Taylor & Francis, 2014)
Non-native fishes threaten native fish communities in many rivers of the world. In South Africa’s Cape Floristic Region, predation by nonnative fishes has severely impacted native fish populations and more than half of the ...
Managing conflicts arising from fisheries enhancements based on non-native fishes in southern Africa.
Southern Africa has a long history of non-native fish introductions for the enhancement of recreational and commercial fisheries, due to a perceived lack of suitable native species. This has resulted in some important ...
