Such initiatives are aimed at restoring access to potable freshwater and maintaining native biodiversity. However, in recent years, there h

Here, we review what is known about invasions to the PEIs for terrestrial taxa (vertebrates, invertebrates, plants and microbes), freshwater taxa and marine taxa. Currently, Marion Island is home to 46 alien species, of which 29 are known to be invasive (i.e. they are alien species that

The association between marine alien species and harbours reflects the importance of shipping as a pathway for introducing novel marine biota. In the South African co

Lösungsvorschlag Musterklausur 5 South Africa’s natural systems are strongly structured by biotic and abiotic features of the region’s biomes, the imprint of these features is much less marked in urban ecosystems that exist as islands of human-dominated and highly modified habitat. Surprisingly little work has been done to documen

While many introductions to South Africa have been intentional, alien taxa have also been accidentally introduced, or have spread unaided into the country from neighbouring countries where they have previously been introduced. Similar to other regions, organisms of different typ

This chapter explores how these environmental features influence biological invasions (focusing on terrestrial ecosystems). We first discuss broad features of the different landscapes, and then discuss how
