3-3 The number of worker ants present in focal domatia varied according to plant age
 and the identity of the ant species. Boxplots show inter-quartile ranges and
 expected minimum and maximum values, with values beyond the 95% CI indicated
 by open circles. Pseudomyrmexfortis was not present in any domatia from 1-yr-
 o ld p lan ts. ......................................................... ................ 5 5

3-4 The proportion of leaf area missing was affected at P < 0.10 by plant age and
 fertilization treatment. In general 1-yr-old plants experienced more proportional
 leaf damage than 5-yr-old plants, and for the 1-yr-old plants fertilization reduced
 herbivore damage. Boxplots show inter-quartile ranges and expected minimum and
 maximum values, with values beyond the 95% CI indicated by open circles.........56

3-5 Fertilization significantly reduced the leaf area consumed by individual Coptocycla
 leprosa beetles in the leaf palatability trials. This was particularly true for young
 leaves, as indicated by the marginally significant (P = 0.056) interactive effect
 between fertilization and leaf age (Table 3-6) ............................................ ............ 57
