The tens rule became a popular invasion hypothesis in the 1990s and is still widely used today, even though empirical support has been mixed from the beginning and the number of studies questioning it has been increasing in the past decade. Here we divide the tens rule into two more specific sub-hypotheses: the invasion tens rule and the impact tens rule, where the former predicts that about 10% of species successfully také consecutive steps of the invasion process, and the latter that about 10% of established non-native species and about 1% of all introduced non-native species cause significant detrimental impacts. A quantitative metaanalysis of 102 empirical tests of the tens rule from 65 publications shows no support for this hypothesis. Looking at the invasion tens rule and comparing different taxonomic groups, about 25% of non-native plants and invertebrates, and about 50% of non-native vertebrates are on average successful in taking consecutive steps of the invasion process. We thus suggest replacing the invasion tens rule by two taxon-dependent hypotheses: the 50% invasion rule for vertebrates and the 25% invasion rule for other organisms, particularly plants and invertebrates.
