The evolutionary genetics of paternal care: How good genes and extrapair copulation affect the trade‐off between paternal care and mating success [PDF]
We investigate the evolution of a gene for paternal care, with pleiotropic effects on male mating fitness and offspring viability, with and without extrapair copulations (EPCs).

Reproductive Strategies in Paternal Care and Remarkably Low Paternity Level in a Giant Water Bug [PDF]
Reproductive strategies are crucial for organisms because they directly affect the organisms' fitness. “Parental care” is one of the strategies adopted by organisms to improve their fitness.

Female extra‐pair behavior is not associated with reduced paternal care in Thorn‐tailed Rayadito [PDF]
Extra‐pair behavior is present in 76% of socially monogamous bird species with biparental care. This behavior may produce costs to females related to a reduction in paternal care.

Paternal Care May Influence Perceptions of Paternal Resemblance [PDF]
Father-child resemblance is increasingly attracting attention from researchers interested in studying paternal investment. The current study sought to determine whether a quasi-experimental infant massage intervention would increase father's perceptions ...

The evolution of extra-pair paternity and paternal care in birds. [PDF]
AbstractExtra-pair paternity (EPP) influences the relatedness between social parents and offspring. Therefore, one might expect the level of EPP to influence levels of paternal investment. Here, we investigated the effect of variation in EPP rates on male contributions to parental care within a phylogenetic framework of up to 271 primarily socially ...

Sexual selection and life history interact to influence the evolution of paternal care [PDF]
Parental care is essential to offspring survival in many species. Understanding why males of some species provide care, whereas others do not, has received substantial attention.

Paternal Care Impacts Oxytocin Expression in California Mouse Offspring and Basal Testosterone in Female, but Not Male Pups [PDF]
Natural variations in parenting are associated with differences in expression of several hormones and neuropeptides which may mediate lasting effects on offspring development, like regulation of stress reactivity and social behavior.

The Evolutionary Loss of Paternal Care Is Associated With Shifts in Female Life‐History Traits [PDF]
Parental care can increase the fitness of parents through increased offspring survival but can also reduce reproductive output by limiting time and energy allocated to additional mating opportunities.

Paternal care has never been reported as absent in any canid species, and some form of care has been seen in 18 of the 36 species in the family. Food provisioning, active defense of the young, and protecting young by remaining at the den as the female forages appear to be the commonest forms of male care. In addition males may groom, retrieve, play and
