Figure 4 : Three hypothetical exotic species or populations (A, B, C) that occur in different contexts (Context ii: relative resource availability) and that are studied in terms of their enemy diversity at different times (t1 vs.t2 ) produce a wide range of possible interpretations (Box 2). Details as per Fig. 3e: exotics that come from high-resource ranges (population A, red line) likely lose a high number of enemies but also accumulate them quickly, while exotics from low-resource ranges (population C, blue line) both lose and accumulate a lower diversity of enemies. Population B is intermediate.
