Sustainable fisheries management

持続可能な水産資源管理 順応的管理

Overfishing is the main threat to sustainable fisheries. To ensure sustainability, we need a solid understanding of ecosystem-level responses to fisheries management and systems to mitigate competitive fishing. We tackle this problem through ecological (e.g., modeling population dynamics) and socioeconomic (e.g., decision theory) approaches.

Terristrial and marine protected areas

陸域・海洋保護区の導入 制度設計

The establishment of terrestrial and marine protected areas is increasing rapidly around the world. This seems good for conservation, but is it always good for society? Establishing a protected area is often very costly and requires a cost-effective strategy for its establishment. In addition to the benefits of protected areas, we also seek to understand effective ways to establish them.

Global biodiversity

生物多様性 保全生物学 マクロ生態学

Bending the curve of global biodiversity loss is a pressing issue in today's society. A comprehensive understanding of global biodiversity is necessary to develop effective conservation strategies. We employ our knowledge of community ecology and macroecology to develop ecosystem models and study the effects of human activities on a global scale and effective conservation management approaches.

Theoretical ecology

数理生態学 数理モデル

We are also interested in a wide range of topics in theoretical ecology, such as ecosystem/population dynamics at various temporal, spatial, and ecological focal scales (e.g., age, role, and species), and ecological sampling theory.

Keywords: Population dynamics, age/size structure, spatially explicit model
