摘要: Abstract Riparian systems are threatened globally, but contribute disproportionately to biodiversity and ecosystem function. Restoration reverse their loss is costly, requires careful monitoring evaluation. Odonates amongst the most reliable arthropod bio-indicators for riparian ecosystems. Despite functional diversity (FD) reflecting pattern processes better than taxonomic diversity, Odonate FD has yet be used in evaluating conservation restoration outcomes. We surveyed 45 sites across six river-systems northeastern South Africa, compare standardised effect size of (sesFD) that had been invaded by alien plants, cleared invasives, never (15 each). Although species richness did not differ between treatments, sesFD was lower those vegetation invaded. Clearance 40% associated with greater almost two standard deviations. Representation traits varied treatments similar natural sites, suggesting invasion plants directly impacts food webs, clearance can restore ecological services. This study confirms respond efforts. Secondary complete suites groups anticipated enhance services impact webs at a range scales.
