Repeatability and heritability of resting metabolic rate in newts

We studied repeatability (over
six months and five years) and heritability (parent-offspring
regression, full-sib analysis) of resting metabolic rate in the alpine
newt, Ichthyosaura alpestris. In addition we examined the influence of
two thermal regimes (12–22°C and 15–25°C) after metamorphosis on the RMR
heritability estimates. estimates.
