The social and defensive function of olfactory behaviors in a pair‐living sexually monogamous primate

“…T A B L E 3 Percent and number of observations (N) that each age-sex category was the recipient of genital inspections or partnermarking (sex distribution for infants is not shown because in all cases infant sex was unknown). Juárez, et al, 2023;Fernadez-Duque, Rotundo, et al, 2023;Gursky & Nekaris, 2019). Still, despite these challenges, field research is necessary to identify the adaptive value of chemical communication (Fawcett et al, 2013;Jordan et al, 2014) Regarding our first prediction that all olfactory behaviors would be more frequently performed by mature adults, our results showed Supporting this, and in line with our second prediction (that genital inspections will be male-biased and used to gather information about a female's reproductive state), our study indicated that there are striking sex differences in genital inspections.…”

Disappearances of individuals from social groups have implications for understanding natal dispersal in monogamous owl monkeys (Aotus azarai)

“…The probability of disappearance might be related to the size of each particular group, not to a population-specific group size. Certain ''small'' groups in the population have never included more than four individuals, whereas ''large'' groups have been observed with five, six, or seven individuals [Fernandez-Duque et al, 2001]. Disappearances recorded from small groups (n ¼ 4 events, 4 groups) only occurred when the groups had reached their historical maximum size of four individuals [see Table II in Fernandez-Duque et al, 2001].…”

Cuidado biparental en el mono de noche (<i>Aotus azarai</i>) de Formosa, Argentina

“…La relativamente alta sobrevivencia de infantes en esta población hasta los seis meses de vida (96%, n = 27 infantes) sugiere que el cuidado paternal puede ser una estrategia exitosa para maximizar el éxito reproductivo del macho (Fernandez-Duque et al, 2002). Si bien los resultados aquí presentados están referidos a un único grupo, constituye éste el primer trabajo que evalúa el cuidado biparental en un grupo silvestre de Aotus y por lo tanto proporciona una base para trabajos futuros.…”
