| dc.description.abstract-translated | Daily energy expenditure (DEE) was examined in the social subterranean rodent
Mashona mole-rat (Fukomys darlingi) by the long-term (24 hours) indirect calorimetry. Individuals´ DEEs were compared with DEEs of grouped mole-rats (groups of 2, 3, 4 and 7) to establish the role of social thermoregulation (?huddling?) in this species at two different temperatures (20 and 30°C). The average DEE of single isolated individual was 1.84 ? 0.25 mlO2 g-1h-1 at Ta = 30°C and 2.99 ? 0.34 mlO2 g-1h-1 at Ta = 20°C. The influence of group size on daily energy expenditure (DEE) was observed. The energy savings rose with the increasing number of individuals up to 33.77% in group of seven. Maximal energy savings at 30°C were reached in group of three animals and did not increase further with an increasing number of animas in the group. Similarly at 20°C the maximal savings were observed when seven animals were present. My results confirm that social thermoregulation is an essential mechanism that saves
energy expenditure of F. darlingi, which is important in the food-scarce underground environment. | eng |
