TLDR
Estimates ofSexual selection gradients on male secondary sexual plumage characters resulting from extrapair paternity in the collared flycatcher Ficedula albicollis are reported, and the importance of this form of sexual selection with that resulting from variation in mate fecundity is compared.About:

Journal ArticleDOI
Why do females mate multiply? A review of the genetic benefits.
TL;DR: It is concluded that post‐copulatory mechanisms provide a more reliable way of selecting a genetically compatible mate than pre-copulatory mate choice and that some of the best evidence for cryptic female choice by sperm selection is due to selection of more compatible sperm.
Journal ArticleDOI
Extra pair paternity in birds: a review of interspecific variation and adaptive function.
TL;DR: The remaining challenges of understanding the relative roles of genes and ecology in determining variation between taxa in the rate of extra paternity are highlighted, and testing for differences between extra‐pair offspring and those sired within‐pair is highlighted.
Journal ArticleDOI
The use of multiple cues in mate choice
TL;DR: It is suggested that in contrast to this expectation, the use of multiple cues can reduce mate choice costs by decreasing the number of mates inspected more closely or the time and energy spent inspecting a set of mates.

Estimating genetic parameters in natural populations using the 'animal model'
TL;DR: This work reviews the recent application of restricted maximum-likelihood "animal models" to multigenerational data from natural populations, and shows how the estimation of variance components and prediction of breeding values using these methods offer a powerful means of tackling the potentially confounding effects of environmental variation.

Lifetime Reproductive Success and Heritability in Nature.
Juha Merilä,Ben C. Sheldon +1 more
TL;DR: Analysis of a large data set from the collared flycatcher Ficedula albicollis confirmed a previous finding that traits closely associated with fitness tend to have lower heritability, but analysis of coefficients of additive genetic variation revealed that trait’s association with fitness was not due to lower levels of VA but was due to their higher residual variance.
