A Reassessment of Age of Sexual Maturity in Gibbons (Hylobates spp.)
From studies of both wild and captive animals, gibbons are thought to reach sexual maturity at about 6 to 8 years of age, and the siamang (Hylobates syndactylus) at about 8 to 9 years. However, a review of the literature reveals that in most cases the exact age of the maturing animals was not known and had to be estimated. This study presents seven case reports on captive gibbons of known age. ...
متن کاملMitochondrial Genome Sequences Effectively Reveal the Phylogeny of Hylobates Gibbons
BACKGROUND Uniquely among hominoids, gibbons exist as multiple geographically contiguous taxa exhibiting distinctive behavioral, morphological, and karyotypic characteristics. However, our understanding of the evolutionary relationships of the various gibbons, especially among Hylobates species, is still limited because previous studies used limited taxon sampling or short mitochondrial DNA (mt...
متن کاملInheritance of Age at Sexual Maturity
Dr. RAYMOND PEARL (1912) was the first worker to suggest that sexlinked factors were involved in the inheritance of fecundity. PEARL used as a measure of fecundity the eggs produced during the winter period. He proposed that two major dominant factors were responsible for high egg production, one of which resided in the sex chromosome. GOODALE (1919) and HURST (1921) each failed to confirm the ...
متن کاملSiamangs (Hylobates syndactylus) and white-cheeked gibbons (Hylobates leucogenys) show few behavioral differences related to zoo attendance.
The effect of visitors on behavior and welfare of nonhuman animals in the zoo has been an active research topic during the last few decades. Although research has variously shown negative or positive impacts of zoo visitors on animals in captivity, previous primate research at Disney's Animal Kingdom suggests the importance of visual barriers in allowing animals to cope with large crowds. Exami...
متن کاملCross-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...
