Brood hiding test: a new bioassay for behavioral and neuroethological ant research
Sociobiology, 2014 We describe a new bioassay for behavioral and neuroethological ant research, the brood hiding test. A group of adult ants is taken out of the nest, confined together with brood and exposed to strong light. Ants may interact with brood, and, in particular,
