Naoki Koyama Emeritus professor


koyama1

I have primarily conducted socio-ecological study on the ring-tailed lemur, a primate species living in the southeast of the Republic of Madagascar. I am also conducting research on vegetation and human activity in the ring-tailed lemur’s habitat from the standpoint of environmental conservation.
