Bufo calamita were exposed to tap water to solutions of urea (up to 1000 mM) and NaCl (up to 250 mM). 2. The effects of season and nutrition on the adaptation to osmotic stress were studied by monitoring body mass, moulting rate, hematocrit, plasma osmolality and the plasma concentrations of urea, chloride and glucose. 3. There were marked seasonal changes in the time of survival in tap water as well as in the ability to acclimate to high concentrations of urea and NaCl. 4. The maximal concentration of urea in the plasma of starving toads was greater in winter (650 mM) than in summer (410 mM), but fed toads also reached winter levels (653 mM) during summer. 5. Salt acclimation was accompanied by urea accumulation in plasma up to 175 mM. 6. Salinities exceeding 454 mOsmol/l of NaCl were lethal.

将海蟾蜍暴露于自来水中以及尿素（浓度高达1000毫摩尔）和氯化钠（浓度高达250毫摩尔）的溶液中。2. 通过监测体重、蜕皮率、血细胞比容、血浆渗透压以及尿素、氯离子和葡萄糖的血浆浓度，研究季节和营养对渗透压应激适应的影响。3. 海蟾蜍在自来水中的存活时间以及适应高浓度尿素和氯化钠的能力存在显著的季节性变化。4. 饥饿蟾蜍血浆中尿素的最大浓度在冬季（650毫摩尔）高于夏季（410毫摩尔），但夏季喂食的蟾蜍血浆尿素浓度也能达到冬季水平（653毫摩尔）。
