Opposing selection and environmental variation modify optimal timing of breeding.

Proceedings of the National Academy of Sciences of the United States of America - 17 Sept 2013

Tarwater Corey E, Beissinger Steven R

Abstract excerpt

Studies of evolution in wild populations often find that the heritable phenotypic traits of individuals producing the most offspring do not increase proportionally in the population. This paradox may arise when phenotypic traits influence both fecundity and viability and when there is a tradeoff between these fitness components, leading to opposing selection. Such tradeoffs are the foundation of life history...
