There are many questions in Nature. Let’s challenge to various things, through understanding these questions.

The Forest Ecology Laboratory (Yamawo Lab.) focuses on biological interactions. Especially, we focus on the evolutionary and ecological responses of plants, which are major producers of terrestrial ecosystems, and the influence they have on other organisms. Our main study fields are Hakkoda Mountain, Shirakami Mountain, and Satoyama around these mountains.
