Figure 6. Appropriation of ancient Chinese folk mythology to illustrate integration of the ERH, SDH, and EICA hypotheses with variation in defense allocation. Sun Wukong, the monkey king (representing a plant species), possesses inherent strength that is limited by the incantation of the golden hoop (A) - specialist herbivores - which keeps him under control. However, when Sun Wukong undertakes a pilgrimage to the west (B) - non-native introduction - the golden hoop is no longer required, allowing a rapid increase in defense capacity (C) - the golden cudgel he acquired on his journey - against the now predominant generalist herbivores. Simultaneously, removing the golden hoop allows a strong and consistent response to variation in generalist herbivore pressure, resulting in a positive correlation between herbivore pressure and allocation to cheaper induced defense (D). This reallocation leads to greater growth consistent with the Evolution of Increased Competitive Ability Hypothesis (E).
