Predators and Prey

by Jill Pruetz, Leakey Grantee Some exciting events have occurred this month, including quite a bit of predation attempts by the Fongoli chimps as well as an encounter with a potential predator. So far this year, we’ve recorded 37 tool-assisted hunting attempts on galago (or bushbaby) prey. This behavior peaks at the beginning more »

In the News
This is the fourth in a series of posts about Sosthene Habumuremyi’s dissertation research on the hormonal correlations of socio-sexual behaviors in female mountain gorillas. Sosthene’s research project combines behavioral data collected in the field with hormonal data analyzed in the lab. The results of this study will characterize the specific behavioral patterns around the time more »

Studying Hormonal Stimuli in Mountain Gorillas Yields Many Clues

Behind the Science, Education, From the Field, Grantee Spotlight, Guest Post
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 »
