(2018)
In deep underground mining operations, field stresses are increasing and may lead to brittle failure in excavations in hard rock masses. Brittle failure indicators include crack initiation and propagation in intact rock, ...
Effect of the presence of brood and fungus on the nest architecture and digging activity of Acromyrmex subterraneus Forel (Hymenoptera, Formicidae)
(Soc Brasileira Entomologia, 2017-01-01)
This study investigated the stimuli that trigger digging behavior inAcromyrmex subterraneus during nest building. The hypothesis was that the presence of the fungus garden and/or brood triggers the excavation of tunnels ...

Energetic cost of digging behavior in workers of the leaf-cutting ant Atta sexdens (Fabricius)
(Sociedade Brasileira de Entomologia, 2013-12-01)
Energetic cost of digging behavior in workers of the leaf-cutting ant Atta sexdens (Fabricius). During nest excavation, leaf-cutting ant workers undergo reduction in their body reserve, particularly carbohydrates. In order ...
