Reproductive Characters and Mating Behaviour of Wild Nomascus hainanus

It is hypothesized that suboptimal habitat quality and limited forest area may contribute to the current mating structure of the Hainan gibbons, but more work needs to be done over a longer period to understand better the sociosexual behaviors of this critically endangered species.

Longitudinal patterns of reproduction in wild female siamang (Hylobates syndactylus) and white-handed gibbons (Hylobates lar)

The data and a review of information on longevity and age at menarche suggest that the actual lifetime reproductive output of a siamang or white-handed gibbon female may often fall far short of the 10 offspring/lifetime originally proposed for these species.

Dispersal and female philopatry in a long‐term, stable, polygynous gibbon population: Evidence from 16 years field observation and genetics

It is argued that in the case of black crested gibbons, dispersal decisions appear to represent highly opportunistic events in response to reproductive opportunities in their natal and neighboring groups.

Observation of intra-group and extra-group copulation and reproductive characters in free ranging groups of western black crested gibbon (Nomascus concolor jingdongensis).

The copulation behavior and breeding pattern of free-ranging western black crested gibbons are described for the first time and indicate a flexible social organization and complex mating system.

Phylogeny of Gibbons (Family Hylobatidae) with Focus on Crested Gibbon (Genus Nomascus)

It is shown, that genetic and acoustic differences between crested gibbon species correlate and, hence, that both in combination or alone can be applied to identify gibbons and to elucidate phylogenetic relationships.

Intragroup and Intergroup Social Interactions in White-Handed Gibbons

One of the least studied aspects of the Hylobatidae is their social behavior. In the past, researchers have attributed this to a general lack of affiliative social interactions due to small group

Primate Documentaries: A Critical Analysis of Their History

Primate nature documentaries have been popular with audiences since their inception in the early 1900s. Audiences trust primate documentaries, but scholars are concerned about how documentaries

Long-Distance Vocal Signaling in White-Handed Gibbons (Hylobates lar)

Singing animals exhibited rapid control over vocal output (call inhibition) in response to short climax-coda components of distant pairs’ songs, supporting the intergroup long-distance signaling hypothesis and providing evidence to support the hypothesis that the greatcall may have evolved a lengthy onset to allow distant receivers to detect the great call sequence before its climax- coda components occur.

Disassociation of social and sexual partner relationships in a gibbon population with stable one‐male two‐female groups

The results indicate that long‐term social partners are often distinct from sexual partners in this population of crested gibbons, indicating a need for integrating long-term behavioral data and genetic research to re‐evaluate gibbon social and sexual relationships derived from concepts of monogamy and pair‐bonding.

Introgression and mating patterns between white-handed gibbons (Hylobates lar) and pileated gibbons (Hylobates pileatus) in a natural hybrid zone

The results suggest that once hybridization occurs, white-handed-pileated-gibbon hybrids can reproduce with either parental species and that the backcrossing and thus introgression may occur in successive generations, with no drastic changes in phenotypic appearance.
