Table 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).
