Abstract

1. 1. Oxygen consumption (V_O2), thermal conductance (C), body temperature (T_b) and evaporative water loss (EWL) of Macroscelides proboscideus were measured at air temperatures from 5 to 38°C. 2. 2. The lowest V_O2 was approximately that predicted for a eutherian of equal body weight. Minimal C was higher than predicted. EWL was high for an arid adapted small mammal. T_bs were stable between 10 to 25°C but increased above 30°C. 3. 3. Captive elephant shrew activity was predominantly nocturnal, although animals were active both day and night. 4. 4. Temperature regulation does not show the usual trends found in arid adapted small mammals.
