摘要
本文报道了泽蛙不同生活周期的生理生态特征:①繁殖期(5月)的耗氧量最大;繁殖期(8月)次之;冬眠期(1月)最小、只占5月的39.38%、8月的54.20%。②肾上腺皮质细胞直径和核直径繁殖期较长,冬眠时显著缩短。③觅食期(10月)肝含水量最多,冬眠时肝含水最少。④与耗氧量降低相适应,冬眠时RBC数目、Hb含量,RBC直径明显低于繁殖期,觅食期。⑤冬眠时,主要能量供给为活动季节里积累在肝脏与脂肪体中的营养物质。
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.
