Abstract

When feeding on figs (Ficus insipida), the bat Artibeus jamaicensis increases dietary sodium density while decreasing potassium density by primarily extracting and ingesting pulp juices rather than other parts of the fruit. 2. Based on urine osmotic pressure, these bats are uniformly dehydrated when they leave day roosts and become rapidly rehydrated (0.5-1 hr) after initiation of feeding. 3. After 2000 hr, and throughout the night there is no difference in urine concentration of free-flying bats compared with bats held in the laboratory without food or water for the same time interval. 4. Mean maximum urine concentration in this species is 972 mOsm/kg.

摘要

当以无花果（Ficus insipida）为食时，牙买加果蝠（Artibeus jamaicensis）通过主要提取并摄取果肉汁液而非果实的其他部分，增加了饮食中的钠密度，同时降低了钾密度。2. 根据尿液渗透压，这些蝙蝠离开日间栖息地时均处于脱水状态，开始进食后迅速补水（0.5 - 1小时）。3. 2000小时后，整个夜间，自由飞行的蝙蝠与在实验室中相同时间间隔内未进食或饮水的蝙蝠相比，尿液浓度没有差异。4. 该物种的平均最大尿液浓度为972毫摩尔渗透压/千克。
