| Abstract: | Summary The capacity to excrete a water load was studied in rats and in two desert rodents (Jaculus orientalis andJaculus deserti) adapted to either 5 or 30°C ambient temperature. The rat is able to eliminate the entire water load regardless of thermal adaptation. Cold-adaptedJ. orientalis andJ. deserti excreted 60% of the water load in comparison to 20–30% in warm-adapted jerboas.At both adaptation temperatures, antidiuretic hormone (ADH) concentration was estimated at maximum diuresis in the two desert species. Though hydration induced a significant decrease in ADH concentration in both species, its level in the plasma remained relatively high. The decrease was more pronounced inJ. orientalis thanJ. deserti.Abbreviation ADH
