Brood translocation and circadian variation of temperature preference in the ant Camponotus mus
1) When a thermal gradient (20-40° C) was established along a laboratory nest, Camponotus mus nurse workers showed a photoperiodic circadian rhythm of temperature preferences for brood rearing. Two different temperatures were daily selected to translocate the brood, i.e. 30.8° C selected at the midd...
