Effects of Age, Sex, and Pelage Phenotype on the Elemental Composition of the Old-Field Mouse

Glennis A. Kaufman and Donald W. Kaufman

 

Abstract

Whole-body elemental composition was examined in laboratory-related old-field mice (Peromyscus polionotus) ranging in age from 0 to 42 days.  Effects of age, sex, and pelage phenotype on dry-weight, live-weight, and lean-dry- and lean-live-biomass concentrations of 13 elements were determined with analysis of variance.  Age was the major factor affecting the concentrations of elements.  Only one element, either sodium or sulfur, in each of the four expressions of concentration was not significantly affected by age.  Sex had a significant effect on only two elements, potassium and zinc, when expressed as dry-weight concentrations and did not have a significant effect on any elements when expressed as live-weight or lean-dry or lean-live-biomass concentrations.  Pelage phenotype had a significant effect on concentrations of strontium when expressed as live-weight or lean-dry or lean-live-biomass concentrations but not when expressed as a dry-weight concentration.  Pelage phenotype had no effect on other elemental concentrations.
