Overcompensation has been reported for many plants where the principal mechanism appears to involve the removal of apical dominance via herbivory of the shoot apical meristem, thus releasing lateral meristems and increasing the growth and fitness potential of the plant (Harris, 1974; Maschinski and Whitham, 1989; Aarssen and Irwin, 1991; Whitham et al.
