Spatially explicit population dynamics in a declining population of the tropical rodent, Bolomys lasiurus
We investigated the effects of food availability, fire, and habitat structure on population rates of increase of the rodent Bolomys lasiurus in forty 4-ha plots distributed over an area of about 200 km2 in Amazonian savannas near Alter do Chão, Pará, Brazil. Mean rodent density over the entire study...
