A genomic predictor for age at sexual maturity for mammalian species [PDF]

open access: yesEvolutionary Applications
Age at sexual maturity is a key life history trait that can be used to predict population growth rates and develop life history models. In many wild animal species, the age at sexual maturity is not accurately quantified.
