DOI: 10.1002/dev.22064
Abstract: In human males, testosterone (T) decreases in the period following the birth of offspring. This decline has been widely interpreted as a facultative neuroendocrine response that facilitates parenting effort. Conversely, research on if (or when)… read more here.

DOI: 10.1007/s10164-018-0553-0
Abstract: Paternal care is relatively uncommon in tetrapods but appears to be the rule in the large aquatic salamanders of the primitive family Cryptobranchidae (North America: hellbenders, genus Cryptobranchus; Asia: giant salamanders, genus Andrias). For the… read more here.

Abstract: Motherhood is characterized by dramatic changes in brain and behavior, but less is known about fatherhood. Here we report that male sticklebacks—a small fish in which fathers provide care—experience dramatic changes in neurogenomic state as… read more here.

DOI: 10.1093/beheco/arz172
Abstract: Male secondary sexual traits potentially function as indicators of direct or indirect fitness benefits to females. Direct benefits, such as paternal care, may be especially important to females in species with biparental care. In an… read more here.

DOI: 10.1093/jmammal/gyz096
Abstract: In mammalian species where infanticide by males is likely, females exhibit counterstrategies to prevent or mitigate the costs of infanticide. One putative mitigation strategy is the “Bruce effect,” in which pregnant or inseminated females exposed… read more here.

Acute peaks of testosterone suppress paternal care: evidence from individual hormonal reaction norms

DOI: 10.1098/rspb.2017.0632
Abstract: A long-standing tenet of evolutionary endocrinology states that testosterone mediates the life-history trade-off between mating and paternal care. However, the support for a role of testosterone in suppressing paternal care is mixed: implantation studies in… read more here.

Jealous females? Female competition and reproductive suppression in a wild promiscuous primate

DOI: 10.1098/rspb.2018.1332
Abstract: Female–female competition over paternal care has rarely been investigated in promiscuous mammals, where discreet forms of male care have recently been reported despite low paternity certainty. We investigated female competition over paternal care in a… read more here.
