The hearts of hibernating mammals have the capacity to function at reduced temperatures of 1 C in contrast to hearts of nonhibernating mammals which undergo ventricular fibrillation during deep hypothermia. Thus, all vital membrane functions continue

o 1. Free-running circannual rhythms of body weight, water consumption and the appearance of scrotal testes, have been demonstrated in the non hibernating ground squirrel. Citellus leucurus. 2. The significance of this in the animal's evolution is di

1. 1. Free-running circannual rhythms in females of the hibernator, Citellus lateralis , have been studied in relation to breeding. 2. 2. It has been demonstrated that, in comparison to controls, females which go through gestation and lactation in th

1. 1. In order to elucidate some of the parameters of the circannual rhythm in heterothermichomothermic mammals, the ground squirrel Citellus lateralis was maintained for 3 years under constant. high ambient temperature (34 C). 2. 2. Results indicate

1. 1. A technique of aortic cannulation has been developed which makes it possible to sample the blood of a hibernating animal in such a way that it does not cause arousal. 2. 2. This procedure makes it feasible to study in detail the blood of animal

1. 1. Plasma potassium and sodium concentrations in active and hibernating ground squirrels were determined using heart puncture and flame photometry. 2. 2. Animals in hibernation with a body temperature of 5°C have a significantly lower plasma pota

1. 1. Continuous hibernation or estivation in Citellus lateralis , C. mohavensis, C. tereticaudus, C. variegatus and C. beecheyi never exceeds about 2 weeks. The frequency of arousal is a function of the ambient temperature, though in the latter four

The phospholipid composition of ground squirrel heart muscle changes during hibernation: more lysoglycerophosphatides are found in the hibernating state than in the active state. Phase transitions inferred from spin label motion occur in the usual ma
