Summary of "Allogrooming in Male-Female Pairs of Captive Owl Monkeys (Aotus nancymaae)."

Owl monkeys (Aotus spp.) are socially monogamous, yet allogrooming is reported to be rare. Because Aotus are nocturnal and arboreal, allogrooming is difficult to observe in natural settings. We observed 21 male-female pairs of captive Aotus nancymaae during 2 nonconsecutive study periods in order to describe the details of allogrooming between mates (partner grooming). We found that grooming bouts are brief and consist of tugging the hair or skin with flexed fingers and/or the mouth. Males groomed females most often, and their rates of partner grooming were negatively related to age. Partner grooming occurred regardless of mating behavior. Camera trap data revealed that the rate of partner grooming (1.50 bouts/h) is greater than that recorded from our direct observations in the early evenings (0.51 bouts/h, in 2013; 0.37 bouts/h in 2003) given that most bouts occurred later in the night. A positive relationship between the rates of the parents' partner grooming and those of their offspring later in life suggests intergenerational transmission. This relationship is influenced by the fathers' rates of partner grooming. We conclude that allogrooming in Aotus is a normal part of their behavioral repertoire that likely serves social functions similar to those in other pair-bonded primates.

Medical and Biotech [MESH] Definitions

A family of the New World monkeys inhabiting the forests of South and Central America. There is a single genus and several species occurring in this family, including AOTUS TRIVIRGATUS (Northern night monkeys).

Congenital conditions in individuals in which male GONADS develop in a genetic female (female to male sex reversal).

A condition occurring in the female offspring of dizygotic twins (TWIN, DIZYGOTIC) in a mixed-sex pregnancy, usually in CATTLE. Freemartinism can occur in other mammals. When placental fusion between the male and the female FETUSES permits the exchange of fetal cells and fetal hormones, TESTICULAR HORMONES from the male fetus can androgenize the female fetus producing a sterile XX/XY chimeric "female"(CHIMERISM).

The female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in human and other male-heterogametic species.

A species in the family AOTIDAE, inhabiting the forested regions of Central and South America (from Panama to the Amazon). Vocalizations occur primarily at night when they are active, thus they are also known as Northern night monkeys.
