Abstract

Colonies of the grass-cutting ant, Acromyrmex landolti fracticornis, ranked potential fungal substrate in field preference bioassays as a function of the dominant grass species in the field in which they were located. Mahalanobis distances between and among colony preferences between and among habitats revealed that there was less variability among colonies within any habitat than between habitats. These results suggest that fungal substrate preferences are environmentally induced, probably as a result of early experience of workers.
