| In this study carried out in the Caetetus Ecological Station, Sao Paulo, southeastern Brazil, a wild group of black lion tamarins was accompanied during 1989 to 1991, to analyse the dietary habits of the species. The scan sampling method was used to gather data. A total of 961 behaviors were recorded, of which feeding occupied 23.3% of the time involved in the behaviors. The major dietary components observed in the black lion tamarins were fruits, tree exudates and animal preys (67.9%, 22.8% and 8.9% respectively). Fruits varied monthly from 47.4 to 97.1 %, being consumed more during the rainy season, while tree exudates varied from 0 to 54.7%, and were consumed mainly during the dry season. The animal prey accounted for 0 to 15.8% of the diet. The most... |

| Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats (dry palm leaves, twigs, under loose bark, in tree cavities). These microhabitats were spatially dispersed among different forest macrohabitats such as swamp forests and dry forested areas. These data indicated that the prey foraging behavior of L. chrysopygus was quite variable, and they used a wide variety of microhabitats, different of the other lion tamarin species. |

| Home-range is the area used by an animal in its daily activities. Home-range studies provide data on species mating systems and territorial behavior. Our main goal was to estimate the Didelphis albiventris (Lund 1840) home-range in Mutum Island, Paraná River, Brazil. The study was carried out in 2008 from March to October on a 19.20 ha grid. The island is part of the Parana River Islands and Floodlands Federal Environmental Protection Area, with vegetation composed by Alluvial Semideciduous Seasonal Forest in a region of Subtropical Wet climate. The sampling effort was 3,360 traps-night resulting in 152 Didelphis albiventris (Lund 1840) captures. Forty-one Didelphis albiventris (Lund 1840) individuals were captured in 42 capture stations, composed by a... |

| In Brazil, bat migrations have been inferred based on seasonal variations in bat abundances observed for several species, probably as a result of variations in temperature and food availability. However, direct evidence of individual medium to long distance (> 10 km) movements, based on marked specimens, is restricted to large frugivorous bats, genus Artibeus (Phyllostomidae). We report the longest bat movement recorded in Brazil, along 113 km in a straight line, difference in altitude of 738 m, from a mixed Araucaria forest in Curitiba, PR, to the Atlantic Forest, Alto Ribeira, SP, by a female Artibeus lituratus (Olfers, 1818), over a period of 14 months. This data is consistent with the occurrence of migratory movements in Neotropical bats, such as... |
