Home-range size and territoriality in Bolomys lasiurus (Rodentia: Muridae) in an Amazonian savanna
Bolomys lasiurus is the only species of rodent commonly found in the savanna of Alter do Chão, central Amazonia. Peak densities during 42 months were less than have been reported from the cerrado biome of central Brazil. However, the population at Alter do Chao appears to be more stable than those i...

Bolomys lasiurus is the only species of rodent commonly found in the savanna of Alter do Chão, central Amazonia.

Many animals were captured over periods greater than 7 months, indicating that either mortality or dispersal was less than in previous studies.
