  abstract = {{T}he world is currently undergoing an unprecedented decline in biodiversity, which is mainly attributable to human activities. {F}or instance, nonnative species introduction, combined with the extirpation of native species, affects biodiversity patterns, notably by increasing the similarity among species assemblages. {T}his biodiversity change, called taxonomic homogenization, has rarely been assessed at the world scale. {H}ere, we fill this gap by assessing the current homogenization status of one of the most diverse vertebrate groups (i.e., freshwater fishes) at global and regional scales. {W}e demonstrate that current homogenization of the freshwater fish faunas is still low at the world scale (0.5%) but reaches substantial levels (up to 10%) in some highly invaded river basins from the {N}earctic and {P}alearctic realms. {I}n these realms experiencing high changes, nonnative species introductions rather than native species extirpations drive taxonomic homogenization. {O}ur results suggest that the "{H}omogocene era" is not yet the case for freshwater fish fauna at the worldwide scale. {H}owever, the distressingly high level of homogenization noted for some biogeographical realms stresses the need for further understanding of the ecological consequences of homogenization processes.},
