Brood defense;Nest defense;Offspring protection Definition Protecting progeny against threats that may cause resource loss, bodily harm, or death Introduction In most species, the risk of extrinsic mortality (mortality due to external forces such as predation) is much higher for young than it is for...

First, the conflict is over parental investment (PI) and not over parenting behaviour. Thus, it is essential to quantify PI according to its ultimate definition, that is, to measure any investment by a parent that enhances offspring fitness at the expense of the parent's expectation for ...

Prolonged performance of nest building resulted in reduced stress response (tendency only) and a positive long-term effect on offspring survival. The mink dams' non-maternal nest building during winter, suggested to be thermal related, might therefore be within the definition of a behavioural need....
