摘要: The longitudinal changes in fecal steroid hormone concentrations and sexual behavior 2 mated/pregnant 3 non-mated female Hokkaido brown bears were investigated during the breeding season. Behavioral estrus (standing) lasted for 14 32 days mated females 25 to 36 females. In females, behavior, such as female-female mounting masturbation, was observed several before after estrous period. mean estradiol-17β higher period than post-estrous period, while progesterone similar trends of
