I am conducting research related to community assembly and biodiversity conservation in Satoyama and urban areas. In recent years, I have also been interested in biodiversity and ecosystem function in cities.
Research
Biodiversity changes by urbanization
Urbanization is leading to the loss of biodiversity. That impacts ecosystems in complex ways—not only through the reduction of green spaces but also via factors such as increased management intensity and light pollution. Therefore, it is essential to comprehensively understand these multifaceted effects. My research addresses themes such as: the environmental factors that constitute urban ecosystems; how biological communities change with urbanization (leading to biotic homogenization); and how interspecific interactions are altered by urbanization. Through this, I aim to provide scientific insights that can help cities and nature coexist.
Urban biodiversity Conservation
The importance of urban biodiversity conservation is increasingly recognized as it becomes clear that cities, with their diverse green spaces such as parks, agricultural land, and street trees, provide valuable habitats for a wide array of species, including endangered ones. My research focuses on the full spectrum of urban green space—from remnant and developed green spaces, down to even minute green elements such as roadside planting strips. The aim is to propose effective conservation strategies for urban biodiversity
Satoyama ecosystems conservation
Satoyama, landscapes traditionally maintained through moderate human use and management over many years, are treasure troves of biodiversity. However, recent challenges such as depopulation and the aging of agricultural workers have led to a withdrawal of human intervention from these areas, resulting in the serious issue of management abandonment. My research addresses to explore new conservation strategies for Satoyama biodiversity that are also adapted to contemporary societal conditions.
