Competing theoretical models make different predictions on which life history strategies facilitate growth of small populations. While ‘fast’ strategies allow for rapid increase in population size and limit vulnerability to stochastic events, ‘slow’ strategies and bet-hedging may reduce variance in vital rates in response to stochasticity. We test these predictions using biological invasions since founder alien populations start small, compiling the largest dataset yet of global herpetological introductions and life history traits. Using state-of-the-art phylogenetic comparative methods, we show that successful invaders have fast traits, such as large and frequent clutches, at both establishment and spread stages. These results, together with recent findings in mammals and plants, support ‘fast advantage’ models and the importance of high potential population growth rate. Conversely, successful alien birds are bet-hedgers. We propose that transient population dynamics and differences in longevity and behavioural flexibility can help reconcile apparently contrasting results across terrestrial vertebrate classes.

The data file contains data on the status of alien (non-native) amphibian and reptile species at the global scale and their life history traits. In the ReadMe file we provide the basic details on the variables in the datafile. Full details on the protocol for the extraction of the data from the literature, classification of the species, and references underling the data can be found in the Supplementary Information of the Ecology Letters paper (Data collection: SI, Section 1.1; Data references: SI, 4.2 and 4.3).
