FERNANDES, Marcus E. B.; ANDRADE, Fernanda A. G. y SILVA JUNIOR, José de S. e. Diet of Micoreus demerarae (Thomas) (Mammalia, Didelphidae) associated with contiguous forests of mangrove and terra firme in Bragança, Pará, Brazil. Rev. Bras. Zool. [online]. 2006, vol.23, n.4, pp. 1087-1092. ISSN 0101-8175. http://dx.doi.org/10.1590/S0101-81752006000400015.
The diet of Micoureus demerarae (Thomas, 1905) was studied in mangrove and terra firme stands by using stomachal and faecal samples. The number of captured individuals was inversely proportional to availability of fruits and insects, being Coleoptera and Hemiptera the most consumed arthropod orders and Passifloraceae and Arecaceae the most ingested fruits. Thus, either fruits variability or their high yield during the dry season seem to explain the increase of captured animals in the terra firme stands, where they originally come from. The food items suggest that this species has an omnivorous diet, independently of the seasonality or distribution of available resources.
