Barrera et al. (2015) studied the diversity of leaf cutting ants along a forest-edge-agriculture habitat gradient. Their study site, in Chaco Serrano of Central Argentina, had forest remnants of various sizes within an agriculture area with wheat, soy and maize. A few colonies of A. silvestrii and Acromyrmex heyeri were found along the forest edge. Acromyrmex crassispinus was the most abundant Acromyrmex species sampled (42% of 162 colonies) and was most abundant in the forest interior. Acromyrmex lundii and Acromyrmex striatus were also present, with the former also found in the forest interior. The latter and A. striatus were the most abundant in the forest edge habitat with A. crassispinus present at a slightly lower density.
