Social monogamy, in which parents cooperate to raise their brood, is relatively common among animals--but true sexual fidelity is hard to find. Recent research has shown that in many species, females once thought to be monogamous bear offspring with different fathers. Even when social bonds are strong, extrapair matings apparently offer evolutionary advantages for both females and males. 

Mate-acquisition and Parental-Care Systems

Courtship in wildlife has always been fascinating to study (Brown 1973). Some questions that can be posed are: Why are some species monogamous and others promiscuous or polygamous? Why do males fight

Evidence for genetic monogamy and female‐biased dispersal in the biparental mouthbrooding cichlid Eretmodus cyanostictus from Lake Tanganyika

It is suggested that E. cyanostictus is both socially and genetically monogamous and that monogamy may result from limited opportunities for polygyny, rather than from reproductive benefits of monogamy.

Size-assortative Pairing and Mate Recognition by the Thickclaw Porcelain Crab Pachycheles Rudis Stimpson, 1858 (Anomura, Porcellanidae)

Paired crabs occurred over a large size range and were strongly size correlated, suggesting the possibility of long-term pairings, and both sexes exhibited aggression towards conspecific strangers of the opposite sex.

Evolutionary advantage of diploidal over polyploidal sexual reproduction.

It is shown that there would be any evolutionary advantage of triploid over diploid organisms, and that diploidal sex is always better than that involving three individuals.

The Myth of the Philandering Man and the Crafty Woman

The monogamous human mating system arises from a unique psychological experience (i.e. falling in love), in which both partners make a conscious decision to choose a mate and establish a long-term

Pair-Bonded Humans Conform to Sexual Stereotypes in Web-Based Advertisements for Extra-Marital Partners

While it was predicted that pair-bonding may liberate advertisers from conforming to sexual stereotypes of male promiscuity and female choosiness, the results here provide further evidence that human mating behavior is highly constrained by fundamental biological differences between males and females.

Multiple paternity in the thalassinidean ghost shrimp, Callichirus islagrande (Crustacea: Decapoda: Callianassidae)

Among 40 ovigerous females collected from the Louisiana Isles Dernieres barrier island, eight (20%) carried egg masses for which more than two paternal alleles were detected, indicating fertilization by multiple males.

Female promiscuity and genetic diversity in passerine birds

This meta-analysis shows that female promiscuity in passerine birds is dependent on phylogeny and associated with male parental care and diet and the problem of causality in comparative analyses is addressed.

Wildlife Behavior and Conservation

This chapter discusses Mate-acquisition, mating systems and Parental Care, and Migration, Orientation, and Navigation, and the role of competition in these systems.
