2-1 Results of ANCOVA testing the effects of plant age on ant species richness, with
 the number of domatia on each plant (logio-transformed) included as a covariate..24

2-2 Results of ANOVA examining the effects of plant age and the identity of the
 dominant ant species on the proportion of domatia occupied. Proportional
 occupancy was arcsine (square root) transformed to improve normality. Only 2-
 and 5-yr-old trees primarily occupied by either Aztecapittieri or Crematogaster
 carinata were included in this analysis (only one tree within these age groups,
 which was dominated by Cephalotes setulifer, was excluded).............................25

2-3 Results of ANOVA testing the effects of plant age and the presence of the two
 numerically dominant ant species (Aztecapittieri and Crematogaster carinata) on
 the proportion of the plant occupied by the third most abundant species, Cephalotes
 setulifer. Proportional occupancy was arcsine (square root) transformed to improve
 normality. Only 2- and 5-yr-old trees primarily occupied by either A. pittieri or Cr.
 carinata were included in this analysis (only one tree within these age groups,
 which was dominated by Ce. setulifer, was excluded). ........................................26

3-1 Results of mixed model analysis testing the effects of plant age and fertilization on
 the number of leaves surrounding focal domatia. ............. .................................... 47

3-2 Results of mixed model analysis testing the effects of plant age and fertilization on
 the total area of leaves surrounding focal domatia.............................................48

3-3 Results of mixed model analysis testing the effects of plant age and fertilization on
 the number of worker ants within the focal domatia..............................................49

3-4 Results of mixed model analysis testing the effects of plant age, fertilization, and
 the number of worker ants on the proportion of leaf area missing. The number of
 ants was loglo-transformed and the proportion of leaf area missing was logit-
 transformed to improve the distribution for this analysis. .....................................50

3-5 Results of mixed model analysis testing the effects of fertilization and the number
 of worker ants present on herbivory for 1-yr-old plants and 5-yr-old plants. The
 number of ants was logl0-transformed and the proportion of leaf area missing was
 logit-transformed to improve the distribution for this analysis. Although the results
 are presented together, the analyses were conducted separately for the two ages...51
