黄鼠进入冬眠状态后,体温显著下降,且伴随出现呼吸,心跳、耗氧量的锐减。呈典型的连续冬眠并没有醒觉交替。黄鼠在冬眠时新陈代谢过程并不停止,只是降低很多。冬眠生活之热能来源主要是脂肪。基于此,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测定。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。活动期平均每日增量消耗为64.87卡/g克,冬眠期则大大降低,仅为0.92卡/g。冬眠黄鼠呈现周期性呼吸模式,并常出现Cheyne-Stokes呼吸,每次呼吸暂停时间平均为3～10 min。
When the gopher enters the hibernation state, the body temperature drops significantly, accompanied by the sharp decrease of respiration, heartbeat and oxygen consumption. A typical continuous hibernation does not wake up alternation. The rat during hibernation metabolism does not stop, just reduce a lot. The main source of heat energy for hibernation is fat. Based on this, we mainly discuss the physiological and ecological characteristics of dormant Daurian ground squirrels, resting metabolism is measured by closed-circuit system respiration. There was a negative correlation between oxygen consumption and ambient temperature in the chrysalis during the dormant period and active period. The average daily consumption during the active period was 64.87 calories per gram, while the hibernation period was greatly reduced to only 0.92 calories per gram. Hibernating squirrels show periodic breathing patterns, and often Cheyne-Stokes respiration, the average duration of each apnea is 3 ~ 10 min.
