KAISER, Silvane Krul; MARGARIDO, Teresa Cristina Castellano  e  FISCHER, Marta Luciane. Behavioral evaluation of captive and semi-captive agoutis Dasyprocta azarae and Dasyprocta leporina (Rodentia: Dasyprotidae), on urban parks of Curitiba, Paraná, Brazil. Rev. etol.

The knowledge of the behavioral repertoire of captive and free-ranging agoutis is essential for the improvement of management techniques. Observations were made in the field of reproduction of the Museu de História Natural do Capão da Imbuia (MHNCI) and in the Passeio Público, while observations in semi-captivity were held in the MHNCI and the Jardim Botânico. The ethogram of Dasyprocta azarae (Lichtenstein, 1923) and Dasyprocta leporina (Linnaeus, 1758) was carried out through in 120h, characterizing 78 behavioral acts, quantified in 96h by the methods focal animal and scan. The frequencies were analyzed using the chi-square test which revealed differences between the environments. In the semi-captivity the frequencies of feeding, agonistics interactions, reproductive interactions and parental care were higher indicating the resources competition and reflection on the reproduction and care for their offspring. In captivity the high incidence of self-directed behaviors, exploratory acts and coespecifics relations emphasize the lack of stimulation and the forced proximity among the animals. Therefore, there are differences in the frequency of behaviors exhibited, possibly due to differences between environments, which may be related to the maintenance conditions of these species.
