Estimating phenotypic selection in age-structured populations by removing transient fluctuations.

Evolution; international journal of organic evolution - 1 Sept 2014

Engen Steinar, Kvalnes Thomas, Sæther Bernt-Erik

Abstract excerpt

An extension of the selection differential in the Robertson-Price equation for the mean phenotype in an age-structured population is provided. Temporal changes in the mean phenotype caused by transient fluctuations in the age-distribution and variation in mean phenotype among age classes, which can mistakenly be interpreted as selection, will disappear if reproductive value weighting is applied. Changes in any...
