Influence of biotic, chemical and mechanical plant defenses on the foraging pattern of the leaf-cutter ant (Acromyrmex striatus) in a subtropical forest
The diet of Acromyrmex striatus was used as indirect evidence for potential antiherbivore activity by the nectivorous ant Camponotus blandus and by chemical and mechanical plant defenses in a subtropical forest in the Argentinean Chaco. There was a negative relationship between the proportion of vis...
