Outline of Final Research Achievements

Habitat destruction is a global environmental problem, and discussions of its conservation at the broad spatial scales that macroecology addresses are indispensable. In this study, we applied the insights of macroecology to describe global ecological patterns and combined them with land use dynamics to investigate qualitative patterns of biodiversity loss that could occur on a global scale. Our results show that under a wide range of scenarios, marginal extinction risk increases with the progression of land use change. On the other hand, the results suggest that the introduction of protected areas can effectively reduce extinction risk, and that the earlier the introduction of protected areas, the greater the conservation benefit.

Academic Significance and Societal Importance of the Research Achievements

年々その甚大さを増す生物多様性の損失は持続可能な社会構築のために解決するべき最重要課題の一つである。本研究では,生態学の長年の研究対象である種の絶滅リスクを,土地利用動態と組み合わせることで社会生態システムの枠組みで議論し,その性質をマクロスケールにおいて包括的に捉えようという試みである。
本研究で得られた知見は,地球規模で進行する生物多様性損失に関するより深い洞察を与え,また保護区が生き物の絶滅リスクを減少させる効果を明示的に議論したことで生物多様性の保全戦略を考える上で重要な示唆を与えると考えられる。
