Winter dispersal in Oligoryzomys flavescens (Rodentia: Muridae) in cropfield borders of pampean agroecosystems
We studied winter dispersal pattern of Oligoryzomys flavescens in cropfield borders using the removal technique. Fifteen days after removal, O. flavescens abundance in removal areas did not differ from that observed in capture-mark-recapture areas. The recovery in removal areas was due to the disper...
