EFFECT OF LOW TEMPERATURE ON THE ISOLATED HEARTS OF CITELLUS LEUCURUS AND C. MOHAVENSIS,
Abstract
The perfused, isolated hearts of two desertliving ground squirrels, Citellus mohavensis and C. leucurus, were exposed to temperatures between 25 and 0 C. Although mohavensis hibernates and aestivates and leucurus does neither, the temperature-rate curves were very similar, and typical of hibernators in general. Leucurus is highly adapted to a diurnal existence in hot arid regions and has a high critical and lethal temperature, yet its heart has not changed its ability to tolerate low temperatures. (Author)
