Food habits and carnivory by a small size opossum, Gracilinanus agilis (Didelphimorphia: Didelphidae) Mastozool. neotrop.
Lessa,Leonardo G; Geise,Lena.
We investigated the diet of gracile mouse opossum, Gracilinanus agilis (Burmeister, 1854), from the analysis of 144 fecal samples collected between November 2009 and October 2011 in an area of savanna riparian forest in the Brazilian Cerrado. Invertebrates were the most frequently consumed food items (96.5%) followed by fruits of pioneer species (29.8%) and flowers (6%). We also observed the presence of fragments of bird vertebrae and downs in samples from 2 adult males, this being the first record of predation on small vertebrates by G. agilis. The presence of fragments of birds in the feces of the gracile mouse opossum suggests that despite the small size of this species and its primarily insectivorous habits, small vertebrates may be included in its diet.

Terrestrial mammals of the Jequitinhonha River basin, Brazil: a transition area between Atlantic Forest and Cerrado Mastozool. neotrop.
Geise,Lena; Pereira,Luciana G; Astúa,Diego; Aguieiras,Marcia; Lessa,Leonardo G; Asfora,Paulo H; Dourado,Francisco; Esberárd,Carlos E. L.
Here we present an extensive survey for non-volant mammals along the margins of the Jequitinhonha River, which represents a contact area between the Cerrado and Atlantic Forest biomes. Our data were ob­tained after 13 trapping expeditions (from 2005 to 2012) on both banks of the river, from its source to its mouth, enriched by data obtained from a literature review and voucher specimens deposited in six mammal collections. All collected specimens were identified through their karyotypes and/or morphology. We obtained data for 75 localities (34 at the rigth margin, 42 at the left margin; 30 in the Cerrado and 45 in the Atlantic Forest). We obtained voucher records for 91 species, ca. 17% of all known Brazilian terrestrial non-volant mam­mals. Our results...
