Resumo(s)
While the regional distribution of non-native species is increasingly well
documented for some taxa, global analyses of non-native species in local
assemblages are still missing. Here, we use a worldwide collection of assemblages from five taxa - ants, birds, mammals, spiders and vascular plants - to
assess whether the incidence, frequency and proportions of naturalised nonnative species depend on type and intensity of land use. In plants, assemblages
of primary vegetation are least invaded. In the other taxa, primary vegetation is
among the least invaded land-use types, but one or several other types have
equally low levels of occurrence, frequency and proportions of non-native
species. High land use intensity is associated with higher non-native incidence
and frequency in primary vegetation, while intensity effects are inconsistent
for other land-use types. These findings highlight the potential dual role of
unused primary vegetation in preserving native biodiversity and in conferring
resistance against biological invasions.
