Studying Hormonal Stimuli in Mountain Gorillas Yields Many Clues

Grantee Spotlight, From the Field, Behind the Science, Guest Post, Education
By Sosthene Habumuremyi My study has gathered data on mating behavior, solicitations, and any displays/aggression from adult males towards the females. Sexual swellings, which are extremely small in gorillas, are also noted. The plan is to monitor at least 6 nulliparous (never having given birth to offspring) females and 10 cycling parous (given birth to offspring at least once) females for 2 cycles … more »

The hormonal correlations of socio-sexual behaviors in female mountain gorillas

Education

By Sosthene Habumuremyi

The overall goal of this study is to investigate the hormonal correlates of socio-sexual behaviors in female mountain gorillas. Specifically, we want to understand the variation observed in mating strategies and fertility parameters among female mountain gorillas. By using hormonal data, we want to know if this variation is governed by internal stimuli. For a detailed analysis,… more »
