Acoustic signalling reflects personality in a social mammal

摘要: Social interactions among individuals are often mediated through acoustic signals. If signals consistent and related to an individual's personality, these individual differences in signalling may be important driver social interactions. However, few studies non-human mammals have investigated the relationship between personality. Here we show that rate is repeatable strongly personality a highly mammal, domestic pig (Sus scrofa domestica). Furthermore, varied environments of differing quality, with males from poor-quality environment having reduced vocalization compared females enriched environment. Such by pigs more reactive extreme scores Our results add evidence reflects mammal. Signals reflecting personalities far reaching consequences shaping evolution behaviours as communication forms integral part animal societies.
