Arquitetura de ninhos da formiga neotropical Ectatomma brunneum F. Smith, 1858 (Formicidae, Ponerinae) em ambientes alterados

Resumo

In this paper we relate the excavation of seven E. brunneum nests in sites altered by human action in Rio Claro SP, southeastern Brazil. This ant nests are poor elaborated, just like in other species of this genus and subfamily. The depths and dispositions of the chambers did not show a defined pattern, nor any complex structure or architecture. We argue that it is due to the fact of this ant has migratory habits, occupying the nest for limited time in relation to their colony life cycle.
