Thermoregulation and oxygen consumption in Kirk's dik-dik (Madoqua kirkii) at ambient temperatures of 10–45°C
Abstract
1.
1. Thermoregulatory and metabolic responses of dik-dik (Madoqua kirkii) were measured over an ambient temperature (Ta) range of 10–45°C.
2.
2. The lower critical temperature was estimated at Ta 25°C.
3.
3. At Ta 40 and 45°C, dik-dik panted and oxygen consumption fell below that measured at thermoneutrality.
4.
4. The dik-dik appears well adapted to a high Ta but can cope with a low Ta only at a high metabolic cost.
