Diet and trophic niche of the endangered fish Garra ghorensis in three Jordanian populations
(John Wiley & Sons Ltd, 2016)
Garra ghorensis is a small riverine cyprinid fish endemic to the southern Dead Sea that is endangered through habitat loss and invasive species. Here, their diet and trophic niche were assessed in three Jordanian populations: ...
Improving credibility and transparency of conservation impact evaluations through the partial identification approach
(Society for Conservation Biology, 2016)
The fundamental challenge of evaluating the impact of conservation interventions is that researchers must estimate the difference between the outcome after an intervention occurred and what the outcome would have been ...
Interactions among multiple invasive animals
(Ecological Society of America, 2015)
With accelerating rates of invasion being documented in many ecosystems, communities of interacting invasive species are becoming increasingly common. Opposing theories predict that invaders can either hinder or promote ...
Reassessing the invasion of South African waters by the European shore-crab Carcinus maenas
(NISC (Pty) Ltd, 2017)
The European shore-crab Carcinus maenas has been present in South Africa since 1983. Despite this species’ international reputation as a biological invader, its distribution in this region has only been considered by three ...
Intergrating invasive species policies across ornamental horticulture supply chains to prevent plant invasions.
(British Ecological Society, 2017)
1. Ornamental horticulture is the primary pathway for invasive alien plant introductions. We critically appraise published evidence on the effectiveness of four policy instruments that tackle invasions along the horticulture ...
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.
Global realized niche divergence in the African clawed frog Xenopus laevis
(John Wiley & Sons Ltd, 2017)
Although of crucial importance for invasion biology and impact assessments of climate change, it remains widely unknown how species cope with and adapt to environmental conditions beyond their currently realized climatic ...
Much more give than take: South Africa as a major donor but infrequent recipient of invasive non-native grasses
(John Wiley & Sons Ltd, 2016)
Aim Some regions donate more invaders from particular taxonomic and functional groups than they receive. We demonstrate a particularly striking donor–recipient asymmetry in invasion ecology in grasses. Specifically, we ...
Invasion dynamics of Lantana camara L. (sensu lato) in South Africa.
Lantana camara L. (sensu lato) has a wide range of impacts throughout its global invasive range. Here we review the mechanisms driving its invasion dynamics in South Africa at national (biome, habitat) and regional (within ...
Reconstructing the spread of invasive alien plants on privately-owned land in the Cape Floristic Region: Vergelegen Wine Estate as a case study.
(Taylor & Francis, 2018)
Invasive alien plants (IAPs) are a major threat to biodiversity in South Africa’s Cape Floristic Region (CFR). Activities like agricultural development, the establishment of forestry plantations and urbanization change ...
