The Djungarian hamster (Phodopus sungorus) shows calm behavior, while the Roborovskii hamster (P. roborovskii) exhibits hyperactivity. Even though they belong to the same genus, Phodopus, these two species are quite different. The current study investigated the relationship between energy expenditure and the markedly different levels of activity shown by these hamsters. Roborovskii hamsters showed significantly higher energy expenditure than Djungarian hamsters under both feeding and fasting conditions during darkness. Roborovskii hamsters showed a repeated increase and decrease in energy expenditure under the feeding condition; however, this changed under the fasting condition, during which the repeated increase and decrease in energy expenditure corresponded to the repeated active and sleeping conditions. Djungarian hamsters had a tendency to keep their energy expenditure constant during the fasting condition, while Roborovskii hamsters moved around a lot to find food. The respiratory quotient (RQ) values in Djungarian hamsters were relatively constant. However, Roborovskii hamsters showed a wide variation in RQ. In particular, the RQ value declined immediately before a dark phase commenced, indicating a switchover from the utilization of glucose to that of lipids as a substrate for energy production. In conclusion, Djungarian hamsters and Roborovskii hamsters showed different behavioral patterns that were related to differences in energy metabolism. |
