|Title:||Effects of resource availability on the use of space by the mouse opossum Marmosops paulensis (Didelphidae) in a montane Atlantic forest area in southeastern Brazil|
|Abstract:||Food supply is an important determinant of animal movements. In the present study we tested the occurrence of an inverse relationship between daily movements of Marmosops paulensis (Tate, 1931) and their food supply. This species is a member of the family Didelphidae, occurring in areas of high elevation in the Brazilian Atlantic Forest. M. paulensis moved mostly over the ground, although the understory was also used. Mean daily range of M. paulensis estimated through spool-and-line device was about 0.40 ha; no differences were noted between body sizes and sexes. As expected, there was an inverse relationship between daily movements and food supply. This relationship resulted from the clumped distribution of fruits, particularly Piper rather than the sparser distribution of arthropods.|
