LACK OF ASSOCIATION BETWEEN PROTEIN HETEROZYGOSITY AND RESTING METABOLIC RATE IN MEADOW VOLES (MICROTUS PENNSYLVANICUS)

The association of resting metabolic rate (RMR) with protein heterozygosity of adult male meadow voles (Microtus pennsylvanicus) was investigated. RMR was determined for voles at temperatures representing energetically non-stressful (27°C) and stressful (3°C) temperatures and protein heterozygosity...

Description
Summary:The association of resting metabolic rate (RMR) with protein heterozygosity of adult male meadow voles (Microtus pennsylvanicus) was investigated. RMR was determined for voles at temperatures representing energetically non-stressful (27°C) and stressful (3°C) temperatures and protein heterozygosity (H) was determined for each individual based on the electrophoretic analysis of five polymorphic loci. Mean RMR of voles did not differ significantly among H classes at either temperature. Similarly, ΔRMR (i.e., change in RMR between 27°C and 3°C) did not differ significantly among H classes. The lack of association between RMR and H conflicts with previous studies involving ectothermic species as well as with two previous studies involving mammals. We suggest that further investigation is necessary to understand the effects of heterozygosity on metabolism in different species and under differing energetic conditions.
