Interactions between propagule pressure, native diversity, and local assembly processes in mediating invasion outcomes

Invasion of ecological communities by introduced species depends on the introduced species’ traits, biotic resistance, and propagule pressure. Each of these factors has been studied individually, but the interactions between them need further attention. For example, propagule pressure is considered an important predictor of invader success, but its effect is likely mediated by native composition and invader traits. Similarly, biotic resistance arises through the effects of local community assembly processes on native-exotic interactions, but is generally studied using native diversity alone. Here we examined interactions between propagule pressure and native community assembly processes in determining exotic species abundance, using spatially-explicit community assembly simulations. This dataset contains the code used for these simulations and the simulated data. , , # Interactions between propagule pressure, native diversity, and local assembly processes in mediating invasion outcomes

## Description of the data and file structure

This dataset contains code and simulated data from a study on the effect of propagule pressure and native community characteristics on the success of a virtual invasive species.
