| Popis: | Isolation calls are emitted by the offspring of many mammalian species when separated from caregivers and siblings. Some studies indicate that isolation call rates constitute a consistent individual trait; others show that the young adjust their vocalization rate to the current situation. We studied this in the house mouse (Mus musculus domesticus) by exploring individual consistencies in pup isolation call rates and their potential modulation in different social situations. We carried out experiments including three treatments (repeated measurements) during consecutive days, all starting with an initial isolation of the pup, followed by (a) a reunion with mother and littermates and a second isolation hereafter, (b) the confrontation of isolated pup with cues of its own nest or (c) with cues of an unfamiliar adult male. The first treatment induced a significant increase, while the others induced significant decreases in pup isolation call rates. Pups showed consistent individual differences in initial call rates across the three days of testing (postnatal days 9-11), which were significantly associated with individual differences in call rates during the different treatments. We conclude that pup isolation calls represent a consistent, trait-like behaviour in the house mouse, which can also express flexibility in response to social cues. |
