Abstract
Here we examine the patterns of reproductive hormones (progesterone and estrone-3 glucuronide, or E1G) in one female hoolock gibbon (Hoolock leuconedys) housed at the Gibbon Conservation Center, throughout the maturation period. Three hundred forty-five fecal samples were collected from the individual over a 5-year period (2012-2017) beginning at the age of 6 years and ending at the age of 11. The average measured progesterone concentration increased from 19.572 ± 1.706 ng/g feces in 2012 to 107.922 ± 12.094 ng/g feces in 2016/17 (p < 0.00001). The average measured estrogen value increased from 1.234 ± 0.063 ng/g feces in 2012 to 2.783 ± 0.274 ng/g feces in 2016/17 (p < 0.00001). This was accompanied by the emergence of a clear hormonal cycling pattern in the 2016/17 samples that was absent in all earlier samples. These data are consistent with the known sexual maturation period for other gibbon species, which typically occurs between the ages of 6 and 8 but shows some variation. To our knowledge, this is the first hormonal study and first data on cycle length for a hoolock gibbon.
期刊介绍:
Recognizing that research in human biology must be founded on a comparative knowledge of our closest relatives, this journal is the natural scientist''s ideal means of access to the best of current primate research. ''Folia Primatologica'' covers fields as diverse as molecular biology and social behaviour, and features articles on ecology, conservation, palaeontology, systematics and functional anatomy. In-depth articles and invited reviews are contributed by the world’s leading primatologists. In addition, special issues provide rapid peer-reviewed publication of conference proceedings. ''Folia Primatologica'' is one of the top-rated primatology publications and is acknowledged worldwide as a high-impact core journal for primatologists, zoologists and anthropologists.
