Extrapair Fertilizations and the Potential for Sexual Selection in a Socially Monogamous Songbird
—Variation in mating success among individuals is the basis for sexual selection and the evolution of elaborate secondary sexual traits. In socially monogamous species, variation in mating success is generally thought to be small, but a skewed adult sex ratio, differences in female fecundity, and extrapair fertilizations that arise from matings outside the social pair bond can increase variance...
متن کاملFertility assurance through extrapair fertilizations and male paternity defense.
Extrapair paternity has been observed in many formally monogamous species. Male pursuit of extrapair fertilizations is explained by the advantages of having offspring that receive essential paternal care from other males. Since females are capable of exercising a degree of control over the post-copulatory sperm competition, extrapair paternity cannot persist unless it confers fitness benefits o...
متن کاملSexual conflict arising from extrapair matings in birds.
The discovery that extrapair copulation (EPC) and extrapair paternity (EPP) are common in birds led to a paradigm shift in our understanding of the evolution of mating systems. The prevalence of extrapair matings in pair-bonded species sets the stage for sexual conflict, and a recent focus has been to consider how this conflict can shape variation in extrapair mating rates. Here, we invert the ...
متن کاملFemale extrapair mate choice in a cooperative breeder: trading sex for help and increasing offspring heterozygosity.
Sexual conflict between males and females over mating is common. Females that copulate with extrapair mates outside the pair-bond may gain (i) direct benefits such as resources or increased paternal care, (ii) indirect genetic benefits for their offspring, or (iii) insurance against infertility in their own social mate. Few studies have been able to demonstrate the different contexts in which f...
متن کاملFertility assurance and breeding synchrony.
Extrapair fertilizations are an important factor in reproduction of many bird species. It has been suggested that pursuit of extrapair fertilizations provides a selective pressure capable of affecting the "ecological" attributes of some bird species. It is known that in some cases the pursuit of extrapair copulations is motivated by fertility assurance. That is, there are populations in which (...
