Resumen:
South American subterranean rodents are mainly described as solitary and mutual synchronization was neverobserved among individuals maintained together in laboratory. We report that a single birth event was capableof disrupting the robust nocturnal activity rhythm of singly housed tuco-tucos from north-west Argentina.?Around-the-clock activity? was displayed by 8 out of 13 animals whose cages were closer to the newborn pups.However, experimental exposure to a pup vocalization did not produce a similar effect on the rhythms of adultanimals. Our results indicate an effect of social interaction in the expression of biological rhythms even insolitary animals.
