Dataset used for analyzing the critical area thresholds for undergoing rapid increases of established non-native terrestrial vertebrates in global islands

Biological invasions are among the threats to global biodiversity and social sustainability, especially on islands. Identifying the threshold of area at which non-native species begin to increase abruptly is crucial for the early prevention strategies. The small-island effect (SIE) was proposed to quantify the nonlinear relationship between native species richness and area but has not yet been applied to non-native species and thus to predict the key breakpoints at which established non-native species start to increase rapidly. Here, based on the extensive global dataset including 769 non-native bird, mammal, amphibian, and reptile species established on 4,277 islands across 54 archipelagos, we detected a high prevalence of SIEs across 66.7% of archipelagos, and approximately 50% of islands have reached the threshold area and thus may be undergoing a rapid increase of biological invasions. SIEs were more likely to occur in those archipelagos with more non-native species introduction eve..., , , # Dataset used for analyzing the critical area thresholds for undergoing rapid increases of established non-native terrestrial vertebrates in global islands

The dataset includes the data used to conduct the generalized linear mixed models for the presence of the small-island effect (SIE) analyses. And the dataset of the species-area relationship models for the established non-native terrestrial vertebrates in global islands analyses.

## Description of the data and file structure

The dataset includes the number of established non-native terrestrial vertebrates per taxon and global islands; the number of established non-native terrestrial vertebrates per taxon and archipelago. And the data was used to analyse the effect of different variables in predicting the presence of SIE based on generalized linear mixed models when using the number of non-native species established earlier on the islands and all t...
