Managing biological invasions: charting courses to desirable futures in the Cape Floristic Region
Invasive species alter the functioning of natural ecosystems, creating ‘‘novel ecosystems’’ comprising species occurring in combinations with no analogs within a given biome. This poses major challenges for managers who ...
Intensifying postfire weather and biological invasion drive species loss in a Mediterranean-type biodiversity hotspot
(National Academy of Sciences, 2017)
Prolonged periods of extreme heat or drought in the first year after fire affect the resilience and diversity of fire-dependent ecosystems by inhibiting seed germination or increasing mortality of seedlings and resprouting ...
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 ...
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 ...
