| Resumo: |
Didelphis albiventris Lund, 1840 is one of the least known Brazilian marsupials with respect to its feeding habits. Since the white-eared opossum is omnivorous, it occupies several niches and may be found in urban areas as well as in forest fragments. Current analysis aimed at determining and comparing the diet of D. albiventris in two periurban areas of the municipality of Viamão, a conserved forest remnant and a degraded area resulting from agricultural activities. Captures of D. albiventris were carried out for a period of 30 months by a sampling effort of 504 trap-nights. Forty fecal samples were collected from 45 captures corresponding to 18 specimens. Diet was determined by fecal analysis. Fruit was the most representative item, at an occurrence of 77.5%, comprising six species of plants, followed by invertebrates (62.5%) and vertebrates (37.5%). Didelphis albiventris displayed a frugivorous-omnivorous habit, with no difference between the sexes with respect to composition and frequency of the items consumed. Since there was a greater diversity of food items and fruits in the more conserved area, seasonal variations in the diet could be detected. Generalist species, such as D. albiventris, may have an important role in the recovery of degraded areas through the dispersal of seeds of species of initial successional stages.
