| Research Abstract |
Reproductive physiology and analysis method for reproductive status survey were studied for the conservation of endangered carnivores such as bear and felid species. As a result
non-invasiveendocrine monitoring method using feces were established for assessing the gonadal activity in cheetah, polar bear and others.
Using the monitoring method reproductive physiology such as ovulation pattern was clarified in Siberian tiger, sun bear and others.
Concentration distribution of fecal sex steroid hormones was studied in Siberian tigers in zoo captivity. The distribution patterns may be able to reveal the sexes and reproductive status in free-ranging tigers.
