  abstract = {{I}dentifying the factors determining the non-native species richness ({NNSR}) in a given area is essential for preventing species invasions. {T}he relative importance of human-related and natural factors considered for explaining {NNSR} might depend upon both the spatial scale (i.e. the extent of the gradients sampled) and the historical context of the area surveyed. {H}ere, using a worldwide database of freshwater fish occurrences, we tested whether the relative influence of human and ecological determinants of non-native fish species establishment at the scale of the biogeographic realm was consistent (i) with that observed worldwide, and (ii) among the different biogeographical realms. {T}he prominent role of human activity in shaping the global (i.e. worldwide) pattern of {NNSR} cannot be directly extrapolated to the biogeographic realms. {F}urthermore, the relationships between human and ecological determinants and {NNSR} vary strikingly across biogeographic realms, revealing a strong context dependency of the determinants of {NNSR}. {I}n particular, the human-related factors play a predominant role in explaining the establishment of non-native species in economically developed realms, while in the other realms environmental characteristics of the river basins best explained geographical patterns of {NNSR}. {I}n the face of future biological invasions, considering both the spatial scale and the historical context of the surveyed area is crucial to adopt effective conservation strategies.},
