Abstract
Urine-concentrating capacity and renal morphology were examined for Akodon azarae, A. iniscatus and A. cursor from different geographic rainfall regim ens. A. azarae and A. cursor rejected sodium chloride solution above 0.45 M , whereas A. iniscatus did not. A. azarae and A. iniscatus may concentrate urine to similar osmolarity values. These values were higher than those obs erved for A. cursor. Percent medullary thickness of the kidney for Akodon w as related to both geographic rainfall regimens and urine osmolarity.
