  1. Results as a function of 30 properties of networks and alien pollinator species. Separate analyses were conducted for each of the three binary outcomes (i.e., unsuccessful, naturalized, and invader). The main contributors include only factors that account for >5% of the variance in whether or not the outcome of the introduction fell within the categories identified by the column heading among our 43,200 simulated introductions. The percentages of those simulations falling into the categories are given to the right of the categories in parentheses
