Restoration of invaded Cape Floristic Region riparian systems leads to a recovery in foliage-active arthropod alpha- and beta-diversity

摘要: The Cape Floristic Region of South Africa is a global biodiversity hotspot threatened by invasive alien plants (IAPs). We assessed the effect plant invasions, and their subsequent clearing, on riparian arthropod diversity. Foliage-active communities were collected from two native one tree species. Alpha- beta-diversity associated compared between near pristine, Acacia-invaded restored sites. Arthropod alpha-diversity at pristine sites was higher than sites, lowest invaded This true for most taxonomic groups with all species suggests general trend towards recovery in after IAP removal. Overall, turnover among significantly influenced invasions having those pattern not evident level individual Although community composition only few significant differences could be detected groups. Assemblage each generally differed similar degrees invasion indicating strong across landscape. Results further suggest that both alpha- can recover removal, given sufficient time, but catchment signatures must acknowledged when monitoring restoration recovery.
