1. During long-term dehydration, the tiger salamander, Ambystoma tigrinum, is able to tolerate high plasma fluid concentration (>550 mOsmole/l.). 2. An increase in plasma solute concentration followed by the production and accumulation of urea accounted for increased plasma concentration during dehydration. 3. The "benevolent bladder" hypothesis proposes that differential reabsorption of water and salts regulates plasma concentration during long-term dehydration.
