Description:

Two groups of tundra voles (Microtus oeconomus gilmorei S e t z e r, 1952) were exposed both to control temperature (17°C) and the cold (4°C). Some physiological parameters involved in adaptation to the cold, such as cold diuresis, food, consumption, weight loss, urinary pH, Na and K were studied. Cold diuresis was found, stabilizing on a certain level after a few days, the same was found for the food consumption. The animals lost weight during the first two weeks of cold exposure, and then began to recover until they reached their original weight again. Badano kilka parametrów fizjologicznych, takich jak: pobieranie pokarmu, utratę ciężaru ciała, wydalenie moczu, jego pH oraz poziom Na i K u dwu grup nornika północnego trzymanych w temperaturze 17°C (kontrola) i 4°C. Pod wpływem chłodu wydzielanie moczu wzrasta nadmiernie, lecz po kilku dniach ustala się na pewnym poziomie (Ryc. 1), tak samo jak i konsumpcja pokarmu (Ryc. 6). Zwierzęta traciły na wadze przez początkowe dwa tygodnie ekspozycji w 4°C, a następnie stopniowo zwiększały swój ciężar, aż do osiągnięcia poczatkowej wartości (Ryc. 5).
