Soil seed banks of remnant and degraded Swartland Shale Renosterveld
(International Association for Vegetation Science, 2013)
Questions: What are the characteristics of soil seed banks in highly endangered renosterveld vegetation and adjacent degraded sites? What is the contribution of the soil seed bank to restoring renosterveld vegetation after ...
Using counterfactuals to evaluate the cost-effectiveness of controlling biological invasions
(Ecological Society of America, 2016)
Prioritizing limited conservation funds for controlling biological invasions requires accurate estimates of the effectiveness of interventions to remove invasive species and their cost-effectiveness (cost per unit area ...
Determinants of the Fynbos/Succulent Karoo biome boundary: Insights from a reciprocal transplant experiment
(Elsevier B.V., 2015)
Boundaries between Fynbos and Succulent Karoo vegetation in the Greater Cape Floristic Region are frequently characterised by sharp transitions from sandy, dystrophic to loamy, mesotrophic soils, together with a more ...
Wild flower harvesting on the Agulhas Plain, South Africa: Impact of harvesting intensity under a simulated commercial harvesting regime for two re-seeding and two re-sprouting fynbos species
(Elsevier B.V., 2014)
We present a simple method for assessing the medium-term sustainability of different flower harvesting intensities (i.e. percentage of number of stems harvested per individual) for two re-seeders and re-sprouters of fynbos ...
Invasive alien trees reduce bird species richness and abundance of mutualistic frugivores and nectarivores; a bird’s eye view on a conflict of interest species in riparian habitats
Invasive alien plants have major ecological effects, in particular in riparian habitats. While effects of alien tree invasions on riparian plants are well studied, effects on animals are less well understood. Invasive alien ...
