“…The time and energy a male expends in feeding one female's offspring will decrease the time and energy he can devote to a second female's offspring. Therefore, a male's help may be `depreciable' or non-shareable (Kleiman & Malcolm 1981). However, the mating systems of most wild canids are poorly known due to their possible to observe individuals directly through multiple pup-rearing seasons and to estimate the amount of parental care provided by all members of family groups.…”

“…Direct caregiving behaviors encompass activities such as holding and feeding, while indirect caregiving behaviors are those that relate to foraging for food or territory defense (Kleiman and Malcolm 1981;Marlowe 1999Marlowe , 2005. The methodology of this study precluded recording of data on indirect care; therefore, the focus will be on direct caregiving.…”

In this paper I examine the intracultural variability of parental and alloparental caregiving among the Aka foragers of the Central African Republic. It has been suggested that maternal kin offer higher frequencies of allocare than paternal kin and that maternal investment in infants will decrease when alloparental assistance is provided. Behavioral observations were conducted on 15 eight-to twelve-monthold infants. The practice of brideservice and the flexibility of Aka residence patterns offered a means to test the effect of maternal residence on parental and alloparental investment. There was significant variation in the frequency of investment and who supplied care to infants depending on whether mothers resided with their kin or their husbands' kin. However, in spite of the variation in allocare, when all categories of caregivers were examined collectively, infants received similar overall levels of care.

“…Among mammals, paternal care is relatively uncommon and has been observed in carnivores, rodents, and primates (Kleiman and Malcolm, 1981). The participation of reproductive males seems to be related to the availability of females, access to the female during the estrus period, predator avoidance, and defense of specific resources (Kleiman, 1977).…”

Hormonal changes related to paternal and alloparental care in common marmosets (Callithrix jacchus)

The physiological mechanisms of parental and alloparental care in cooperatively breeding nonhuman primate species such as the common marmoset (Callithrix jacchus) are poorly known. In this study, we examined prolactin and cortisol plasma levels of fathers and older offspring of both sexes, with and without previous experience in infant carrying, around parturition and during infant carrying. Blood samples were collected from fathers and older offspring and prolactin and cortisol were measured by RIA and EIA, respectively. Prolactin levels of both caretakers were not influenced by infant's birth, previous experience or proximity to parturition. However, prolactin levels increased in both caretakers while in physical contact with infants and also with the number of infants being carried in older offspring. These findings suggest that increased prolactin seems to be mainly due to physical effort rather than a physiological trigger of paternal and alloparental care in common marmosets. Cortisol levels were higher for experienced fathers shortly before parturition which could act to reinforce affiliative bonds between breeding males and females at this time or in the ability of males to detect the proximity of the parturition or both.
