The design and operating characteristics of a heart rate transmitter designed for a wild grizzly bear (Ursus arctos) study is described. The rigid capsule is durable and is easily implanted in the field. The transmitter can be regularly monitored at 4-5 km and has a life expectancy of about 1 year in bears which experience winter torpor, and thus reduced heart rate, for about 7 months in northern Alaska.
本文描述了一种为野生灰熊(棕熊)研究设计的心率发射器的设计及操作特性。该硬质胶囊耐用且易于在野外植入。该发射器可在4 - 5公里外进行定期监测,在阿拉斯加北部经历约7个月冬季蛰伏(心率因此降低)的熊体内,其预期寿命约为1年。
