This paper reports the physio—ecological features of R. limnocharis in different periods. The results of the research from May,1989 to May 1990 call be summaried as follows: 1. The rate of oxygen consumption of R.limnocharis varies in different periods, the highest rate is in breeding season and the lowest rate is in hibernating season which is only 39.38% of that in breeding season (May), 54.20% of that in foraging season (October). 2. The diameters of nucleus and cell of cortical cell of adrenal gland are the longest in breeding season, the shortest in hibernating season (January). 3. The moisture of liver tends to decrease from foraging season to hibernating season. 4. Compared with breedig, foraging season, the haemoglobin concentration, erythrocyte counte, erythrocyte diameter significantly decrease in hibernating season. 5. In hibernation, the main energy supplies are nutritional materials stored in liver and fat body.
