Return to preferred habitats (edges) as a function of distance in Akodon azarae (Rodentia, Muridae) in cropfield-edge systems of central Argentina

We studied the ability of Akodon azarae (Rodentia, Muridae) to return to their preferred habitat, when released at a perpendicular distance (25, 50 or 75 m) from the edge towards the cropfield, and a parallel distance (100 m) away from the site of first capture within the edge habitat. Return succes...
