Abstract:
1. 1. The green toad (Bufo viridis) reaches in Israel the southern limit of its distribution and penetrates arid zones. Throughout the dry season (6-8 months) it stays out of the water and uses protective terrestrial shelters. 2. 2. In the present study green toads were tested in the laboratory following their prolonged exposure to terrestrial conditions in drying soil. 3. 3. After three months in the soil blood plasma concentration of the toads reached a maximum of 1400 mOsm/kg with an urea concentration of 900 mM. Intracellular urea concentration in the muscles of these toads amounted to only 500 mM. 4. 4. Linear correlations were demonstrated between plasma osmolality and plasma urea concentration and between plasma urea concentration and urea concentration in the muscle. © 1984.
