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.
