Hypertrichosis in a gibbon (Hylobates muelleri).

Species Discrimination of Male Song in Gibbons

Acoustic analyses and field playback experiments were conducted to investigate interspecific song differences and discrimination in male gibbons. Songs were recorded and analyzed from males of three populations: agile gibbons (Hylobates agilis) in West Kalimantan and South Sumatra and Miiller’s gibbons (Hylobates muelleri) in East Kalimantan. Male songs from each of the three populations were p...

Cross-species amplification of human microsatellite markers using noninvasive samples from white-handed gibbons (Hylobates lar).

Analysis of the population genetic structure and reproductive strategies of various primate species has been facilitated by cross-species amplification (i.e., the use of microsatellite markers developed in one species for analysis of another). In this study we screened 47 human-derived markers to assess their utility in the white-handed gibbon (Hylobates lar). Only eight produced accurate, reli...

A complete species-level phylogeny of the Hylobatidae based on mitochondrial ND3-ND4 gene sequences.

The Hylobatidae (gibbons) are among the most endangered primates and their evolutionary history and systematics remain largely unresolved. We have investigated the species-level phylogenetic relationships among hylobatids using 1257 bases representing all species and an expanded data set of up to 2243 bases for select species from the mitochondrial ND3-ND4 region. Sequences were obtained from 3...

Cerebral infarction and myocardial fibrosis in a white-handed gibbon (Hylobates lar).

A white-handed gibbon (Hylobates lar) lost the use of its right hand. Complete blood count, serum chemistry profile, electrocardiographic findings, blood pressure, and radiographic work-up were normal, but the gibbon died 2 days later. The gibbon was serologically positive for herpes simplex I and Epstein-Barr virus. Necropsy and histopathology showed acute infarction of the right cerebrum and ...
