Basal metabolic rate (BMR) of the European pine vole Pitymys subterraneus (de Sélys-Longchamps, 1836) with typical black agouti coat colour (A) is 2.78 cc O2 g"1 hr" , and in voles with diluted fur pigment (D) it is 3.06 cc O2 g"1 hr"1. The difference of BMR between the voles of A and D morphs is not significant. Resting metabolic rate (RMR) was determined at ambient temperatures (Ta) -10°C, 0°C, 6°C, 12°C, 24°C and 30°C. P. subterraneus of A morph decrease RMR from 9.21 (at -10°C) to 4.80 cc O2 g"1 hr 1 (at 30°C) while the voles of D morph decrease RMR from 10.43 to 4.01 cc O2 g"1 hr'1, respectively. The differences of RMR between the voles of A and D morphs are significant at Ta -10°C, 0°C, 6°C, 24°C, and 30°C. Maximum oxygen consumption rate (VO2NA), after injection of noradrenaline, is not dependent on Ta (measurements were made at -10°C, 0°C, 12°C and 24°C). It equals 8.96 cc 02 g"1 hr"1 in P. sub­terraneus of A morph and 10.18 cc O2 g"1 hr"1 in the voles of D morph, and the difference is significant.
