The status and distribution of newly identified endemic galaxiid in the eastern Cape Fold Ecoregion, of South Africa
(John Wiley & Sons, Ltd., 2018)
1. DNA‐based studies have uncovered cryptic species and lineages within almost all freshwater fishes studied thus far from the Cape Fold Ecoregion (CFE) of South Africa. These studies have changed the way the CFE is viewed, ...
Out of the pot and into the fire: Explaining the vulnerability of an endangered small headwater stream fish to black-bass Micropterus spp. invasion
(The Fisheries Society of the British Isles, 2018)
Introduced predatory fishes have had consistently severe consequences for native fishes in stream environments around the world, although the drivers of these effects are often unclear. In the Swartkops River headwaters ...
Impacts of mussel invasions on the prey preference of two native predators
(Oxford University Press, 2018)
Biotic invasions can result in the displacement of native species. This can alter the availability of native prey and the choices made by native predators. We investigated prey selection by 2 native South African predators, ...
Are private and social goals aligned in pasture-based dairy production?
(Elsevier Ltd., 2018)
To become more sustainable, dairy farms should aim to maximise productivity at a minimum cost to the environment. Standard environmental impact measures were combined with non-parametric total factor productivity analysis ...
Effect of temperature on seed production in the invasive grass Glyceria maxima (Hartm.) Holmb. (Poaceae) in South Africa
(NISC (Pty) Ltd, 2018)
Temperature is one of the main factors that determine sexual reproduction in terrestrial and emergent aquatic plant species. The effect of temperature on sexual reproduction and seed production of Glyceria maxima (Hartm.) ...
Habitat use responses of the African leopard in a human-disturbed region of rural Mozambique
(Elsevier GmbH., 2018)
Leopard (Panthera pardus) populations across Africa are increasingly exposed to high levels of anthropogenic disturbance, and information on habitat use responses of leopards in human-disturbed landscapes can help inform ...
Plasticity and cross-tolerance to heterogeneous environments: divergent stress responses co-evolved in an African fruit fly
(European Society for Evolutionary Biology, 2018)
Plastic adjustments of physiological tolerance to a particular stressor can result in fitness benefits for resistance that might manifest not only in that same environment but also be advantageous when faced with alternative ...
Managing consequences of climate-driven species redistribution requires intergration of ecology, conservation and social science
(Cambridge Philosophical Society, 2018)
Climate change is driving a pervasive global redistribution of the planet’s species. Species redistribution poses new questions for the study of ecosystems, conservation science and human societies that require a coordinated ...
Quantifying multiple-site compositional turnover in an Afrotemperate forest, using zeta diversity
(Springer Open, 2018)
Background: Species turnover is typically measured by partitioning diversity components into alpha and pairwise beta diversity. However, alpha and beta components cannot express the full spectrum of multiple-site compositional ...
Patterns and processes of alien plant invasions in small urban areas in South Africa: The Berg River Catchment as a case study (RIEBEEK KASTEEL)
List of identified alien plant species in the small town of Riebeek Kasteel, Western Cape, South Africa, from waypoints taken every 10m on each side of all public roads in the town.
