一般講演(口頭発表) F1-04 (Oral presentation)
We can learn much about the condition of an environment from seasonal dynamics, habitat utilization and spatial distribution of frogs. In this talk, we utilize these to describe different conditions of satoyama, a traditional rural production landscape, in Kanazawa. Satoyama is one of Japan’s biodiversity hotspots which provide various ecosystem services. Currently, Satoyama is threatened due to the underuse, even abandonment of forests and farmlands, caused by the human aging and depopulation in Japan. Fewer people manage paddy fields, resulting in decrease of satoyama area. As a response to habitat deterioration, three satoyama biotopes have been constructed around Kanazawa University Kakuma campus area to for satoyama restoration. The biotopes were aimed to serve a purpose as biodiversity buffer, creating landscapes similar to satoyama, which provide breeding, foraging and living habitats for organisms, including frogs. Through our study, we would like to know the effects of these biotopes to frog community and population. For that purpose, we try to describe the potentials based on our two years frog population monitoring, and discuss the condition of biotopes in terms of seasonal dynamics, and spatial utilization of frogs.
