  1. § The numbers in parentheses indicate the numbers of native plant and native pollinator species, interaction links between native plants and native pollinators, and individuals of native pollinators visiting native plants.
  2. £ The numbers in parentheses indicate connectance and NODF calculated from the native plant–pollinator interactions (i.e., excluding associations with exotic species).
  3. * P < 0.05 (Model I); other NODF values, P > 0.05 (Model I and/or II).
