  1. Selection ratios of tree, bamboo, shrub, and liana are calculated for each group based on percentage of stem density accounted for by the plant species in continuous forest (Continuous A and Continuous B) and forest fragments (Patchy and Hilltop)
  2. aRank ordered based on annual diet of plant species used for selection ratio. We were unable to calculate dietary preference for forbs and graminoids because their abundance could not be determined in the same manner as for the other plant growth forms
