Seminar ReportiTHEMS Biology Seminar by Haruka Kitayama on April 4, 2024
This time, I invited Mr. Haruka Kitayama from Hokkaido University to give a seminar on fieldwork and genomics of African monkeys. First, there was a description of mixed-species groups of two types of monkeys living in the forests of Uganda. Next, there was an explanation of the impact this mixing has on the genetics of the two species of monkeys. In particular, the topic of genetic penetration seemed relevant to microbiology. Finally, the discussion touched not only on genetic penetration of individuals, but also on the penetration of gut bacteria in individuals, which was very interesting. Reported by Daiki Kumakura
