“…For instance, siamang fathers are often involved in allomaternal care by carrying infants during their second year of life (Alberts 1987 ; Chivers 1974 ; Lappan 2008 ). Additionally, siamangs appear to have more cohesive groups than white-handed gibbons and pileated gibbons ( H. pileatus ) (Chivers 1976 ; Geissmann et al 2020 ; Palombit 1996 ), and may even have a stronger pair-bond than other gibbon species (Geissmann et al 2020 ). Munir ( 2018 ) reported siamangs’ success and high potential in cognitive tests.…”

Cooperative behaviors among individuals of numerous species play a crucial role in social interactions. There is a special interest in investigating the occurrence of cooperation among apes because this knowledge could also shed light on evolutionary processes and help us understand the origin and development of cooperation in humans and primates in general. Gibbons are phylogenetically intermediate between the great apes and monkeys, and therefore represent a unique opportunity for comparisons. The aim of the present study was to discover whether or not white-handed gibbons (Hylobates lar) show cooperative behaviors. In order to test for the respective behaviors, the gibbons were presented with a commonly used experimental cooperative rope-pulling task. The gibbons in this study did not exhibit cooperative behaviors during the problem-solving task. However, prior training procedures could not be fully completed, hence this project constitutes only the onset of exploring cooperative behaviors in gibbons. Additional behavioral observations revealed that the gibbons spent significantly more time “out of arm’s reach to everyone”, suggesting that they are less often involved in social interactions, than other, more cooperative primates.

“…Florkiewicz et al, 2018). One example of synchronous activity in gibbons includes vocal duetting, where songs strengthen social bonds and advertise territorial boundaries (Geissmann, 1993). However, this does not necessarily suggest that chimpanzees do not exhibit facial synchrony or that gibbons are unable to maintain multiple relationships with others.…”

“…While there is variability in the quality (B. Florkiewicz et al, 2018; Geissmann et al, 2020) and quantity (Barelli et al, 2013) of social relationships among gibbons, most live in relatively small social groups consisting of one set of pair-bonded individuals and their offspring (R. Palombit, 1994).…”

Primate facial musculature enables a wide variety of movements during bouts of communication, but how these movements contribute to signal construction and repertoire size is unclear. The facial mobility hypothesis suggests that morphological constraints shape the evolution of facial repertoires: species with higher facial mobility will produce larger and more complex repertoires. In contrast, the socio-ecological complexity hypothesis suggests that social needs shape the evolution of facial repertoires: as social complexity increases, so does communicative repertoire size. We tested these two hypotheses by comparing chimpanzees (Pan troglodytes) and gibbons (family Hylobatidae), two distantly related apes who vary in their facial mobility and social organization. While gibbons have higher facial mobility than chimpanzees, chimpanzees live in more complex social groups than gibbons. We compared the morphology and complexity of facial repertoires for both apes using Facial Action Coding Systems designed for chimpanzees and gibbons. Our comparisons were made at the level of individual muscle movements (action units [AUs]) and the level of muscle movement combinations (AU combinations). Our results show that the chimpanzee facial signaling repertoire was larger and more complex than gibbons, consistent with the socio-ecological complexity hypothesis. On average, chimpanzees produced AU combinations consisting of more morphologically distinct AUs than gibbons. Moreover, chimpanzees also produced more morphologically distinct AU combinations than gibbons, even when focusing exclusively on AUs present in both apes. Therefore, our results suggest that socio-ecological factors were more important than anatomical ones to the evolution of facial signaling repertoires in chimpanzees and gibbons.

“…While our results support male-biased investment in general, whether grooming is sex-biased or equal has been debated as many studies presented controversial results, even within Hylobatidae (reviewed in [ 18 ]). For instance, in wild H. lar , studies have found male-biased grooming in three pairs, female-biased grooming in two pairs and equal grooming in one pair [ 42 , 70 – 72 ], and the results are more complicated when including other genera in Hylobatidae or species in captivity [ 18 , 73 ]. This controversy might be because of the different social and reproductive contexts.…”

How to be a good partner and father? The role of adult males in pair bond maintenance and parental care in Javan gibbons

In pair-living species, female and male pairs may maintain stable social bonds by adjusting spatial and social associations. Nevertheless, each sex invests differently to maintain the pair bond, and the investment can depend on the presence of paternal care or ‘male services.’ While most species live in pairs, the sex responsible for pair bond maintenance in gibbons is still controversial. We investigated pair bond maintenance and parental care in three pairs of wild Javan gibbons in Gunung Halimun-Salak National Park, Indonesia, for over 21 months. We found that Javan gibbon fathers groomed their offspring more than adult females, especially as offspring got older. While both parents increased playing time with offspring when offspring became older and more independent, fathers played with offspring 20 times more than mothers on average. Grooming within Javan gibbon pairs was male-biased, suggesting that pair bond maintenance was heavily the job of males. However, offspring age as a proxy for paternal care did not affect the pair bond maintenance. Our study highlights that adult male Javan gibbons may have an important role in pair bond maintenance and the care of juveniles.
