まだ今年(2021年)の5月に着任したばかりで、ここ帯広で何ができるか模索中です。学生さんからも面白い研究テーマがあればどしどし提案してください。
また生き物のフィールド調査は体力・精神共にとてもしんどいものです。学生同士の協力が必要不可欠になります。さらにフィールド調査だけではなく、多くの文献を読んだり、データ解析を延々としたりと机上作業も多くこなさなければ動物研究は「ただの趣味」になってしまいます。両方できる器用な人はそんなにいませんが、両立を目指す意欲は必要です。
私の研究室では宗岡教授と木村准教授の3人体制で学生指導に当たっています。一つの研究室に引きこもらず、幅広い知見に触れてください。

Self introduction |
I was born and raised in Fukuoka prefecture in Japan. Although most of my researches and jobs were related to the eingineering field, my Ph.D thesis was about ecological engineering. With involving in agricultural civil engineering, my research focuses on the species living in the paddy field, rural area, and so on. |

Island ecology is known worldwide as a biodiversity hotspot. Naturally, Japan is one of these islands. The number of endemic species that can be seen only in Japan surpasses those of the US or the European continent (e.g., amphibians and reptiles). What supports the richness of the Japanese ecosystem is that what we call “the Land of Abundant Reed Plains and Rice Fields”, the rural and agricultural environment created and protected by our ancestors. It is not a virgin-state-nature, but a fertile ecosystem created by the human hands, where the balance between human activities and the survival of plants and animals existed.
However, the post-WWII energy revolution and the declining birthrate and an aging population have exhausted rural society itself, and at the same time, biodiversity has been rapidly disappearing. The investment in infrastructure aiming to recover the exhausted rural communities has led to a vicious cycle of further deterioration of the species habitat. As a result, the once harmonious relationship between humans and plants has turned hostile.
We will research to clarify the actual conditions of the organisms that live in rural societies and find a way to coexist with us once again.
