Evidence of Competition Between Two Canopy Ant Species: Is Aggressive Behavior Innate or Shaped by a Competitive Environment?

<table>Aggressiveness index (mean and standard deviation) for each treatment of laboratory experiments (dyadic encounters) in which “control” is the manipulation with individuals from the same colony and species; “different species” between <i>C. rufipes</i> from Itacolomi State Park (Itacolomi) and <i>C. sericeiventris </i>from Campus of Federal University of Juiz de Fora (UFJF); “same species” between <i>C. rufipes</i> from both Itacolomi and UFJF; “neighbours” between <i>C. rufipes</i> and <i>C. sericeiventris</i> from UFJF.</table>
