Abstract
The heart rate, respiration rate and body temperature of the short-tailed shrew were recorded from a colony of 52 shrews captured alive in the vicinity of Stowe, Vermont, and maintained in the laboratory. The mean heart rate of 20 shrews under pentobarbital sodium anesthesia was 760 beats per minute, and for 10 shrews under ether anesthesia it was 740 beats per minute. The mean body temperature of 25 shrews taken rectally at four different periods of the day was 38.5° C. The mean respiration rate for 5 shrews recorded during twelve separate runs under controlled conditions of temperature and oxygen was 164 per minute.
