- Diet of Didelphis albiventris Lund, 1840 (Didelphimor phia, Didelphidae) in two periurban areas in southern Brazil Alexandre Rodrigues da Silva Eduardo Dias Forneck Sérgio Augusto de Loretto Bordignon Cristina Vargas Cademartori Biología White frugivory eared opossum feeding habits Atlantic Forest Didelphis albiventris Lund, 1840 is one of the least known Br azilian 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-n ights. 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%, compri sing 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 comp osition and frequency of the items consumed. Since there was a greater diversity of food items and fruits in the more conserved area, se asonal 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 seed s of species of initia l successional stages. 2014 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187130419014 en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
