The present paper deal with ecophysiological characteristics in hibernating ground squirrels (Citellus dauricus). Resting metabolic rate was measured using a closed-system respirometer (Wang et al., 1980); the electrocardiogram was recorded by type XDH- 3 electrocardiograph.1. The metabolic rate of ground squirrel was determined at different temperatures ranging from 0℃. to 35℃.Oxygen consumption was negatively correlated with ambient temperature in hibernating and activity states (Table 1 ;, Fig. 1 ).

The present paper deal with ecophysiological characteristics in hibernating ground squirrels (Citellus dauricus). Resting metabolic rate was measured using a closed-system respirometer (Wang et al., 1980); the electrocardiogram was recorded by type XDH- 3 electrocardiograph.1. The metabolic rate of ground squirrel was determined at different temperatures ranging from 0℃. to 35℃.Oxygen consumption was negatively correlated with ambient temperature in hibernating and activity states (Table 1 ;, Fig. 1 ). The mean daily energy consumption in activity state was 64.87cal/g; whereas it was greatly reduced in hibernating state, being 0.92cal/g only.2. The number of leucocytes (2427.80/mm3) in hibernating state was only 38.5% of that in activity state (6304.30/mm3), while the number of erythrocytes (7.07million/mm3) in hibernating state was higher than in activity state.3. The hibernating ground squirrel displayed a periodic respiratory pattern and often exhibited characteristics of Cheyne-Stokes respiration. Apneic periods averaged 3 to 10min.4. Cardiac activity in hibernating ground squirrel was characterized by arrhythmia. The heart rate was low in the hibernating ground squirrel and averaged 5.55 beats/min.

本文主要讨论冬眠达乌尔黄鼠的生理生态特征。静止代谢以闭路系统呼吸计测定。心电图以XDH-3型心电图仪记录。 1.冬眠期与活动期黄鼠的耗氧量与环境温度间的关系均呈负相关(表1、图1)。活动期平均每日能量消耗为64.87卡/克,冬眠期则大大降低,仅为0.92卡/克。 2.冬眠期白血球(2427.80个/立方毫米)仅为活动期(6,304.30个/立方毫米)的38.5%;而冬眠期红血球(707.80个/立方毫米)却增加12.7%. 3.冬眠黄鼠呈现周期性呼吸模式,并常出现Cheyrie-Stokes呼吸,每次呼吸暂停时间平均为3—10分钟。 4.冬眠黄鼠心脏活动不规律,心率低,冬眠期平均心率为5.55次/分。

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 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.

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。

Both the true steppe of North China and the mixed prairie of North America are situated in the inland regions of mid-latitudes of the Northern Hemisphere. The plant communities are similar in structure because of the climatic similarities of the two regions. Basically the vegetation of both over most of their range are supported by the grassland types of the perennial bunch and rhizomatous grasses. The basical live forms of elements in the communities are perennial and subshrubby. Bunch grasses and rhizomatous...

Both the true steppe of North China and the mixed prairie of North America are situated in the inland regions of mid-latitudes of the Northern Hemisphere. The plant communities are similar in structure because of the climatic similarities of the two regions. Basically the vegetation of both over most of their range are supported by the grassland types of the perennial bunch and rhizomatous grasses. The basical live forms of elements in the communities are perennial and subshrubby. Bunch grasses and rhizomatous grasses are important and form dominant synusiae. Within the dominants and common species some ones are physiogically or ecologically similar and some are, genetically related and even same ones between the two continents. There is a difference in structure of taxon, for example, the species of legume and their forages are richer in the true steppe of North China than in the mixed prairie of North America. Because the hydrothermal patterns from the climate are different, there are different proportions of photosynthetic pathway types in the grass flora of the two regions. The Ct grasses are 18%~36% in the northern mixed prairie and 7%'-'12% in the mesothermal-true steppe.

中国北方典型草原和北美北部混合型草原均处在北半球内陆中纬度地区.由于气候条件的相似性,两地草原的群落特征表现出某些相似之处.两地草原的优势植物和某些常见种不仅有着相以或相同的生理生态特征,还有着较为密切的亲缘关系,有些种为两个大陆所共有.由于两地草原夏季的降水条件不同,植物群落的夏季季相有较大差异.
