An introduced species must successfully pass through three filters in order to become established. The relevance of the environmental filtering (EFH), competition-relatedness (CRH), evolutionary imbalance (EIH), universal tradeoff (UTH), and competitive constraint (CCH) hypotheses may change as the species passes through these filters.
