| Sumario: | A previous experiment suggested that male degus, Octodon degus, use dustbathing during intrasexual communication. Herein, we assessed whether dustbathing by male and female degus is influenced by the social familiarity of previous marks. During 15-min tests, we contrasted the behavior of degus individually exposed during to an arena containing loose, previously dustbathed sand by a same-sex and socially familiar individual with that of degus exposed to an arena with soil previously dustbathed by a same-sex but socially unfamiliar conspecific. We measured the number of dusbathing eventts per min, the latency of first dusbathing event, and the location of dusbathing events by depositor and responser individuals. Both male and female degus dusbathe at a higher rate when subjected to soil previously used by a familiar conspecific tha when exposed to a substratum previously dusbathed by an unfamiliar degu. The latency of first dusbathing event by responser male or female degu was unaffected by the social familiarity of previous marks left by depositors. Similary, the place chosen by male and female responders to conduct their dusbathing behavior was unrelated to the micro-location of previous marks left by a familiar or an unfamiliar depositor degu. We conclude that degus are capable of discriminating socially familiar fron unfamiliar scents of conspecifics and deposited in the substratum during dusbathing . We discuss the implications of such ability in the context of degu social bahavior. |
