Using arboreal land snails to index forest environments

Research grant

Project Description

Forests are an important habitat for many living things. However, treeborne biodiversity has not often been targeted by conservation efforts due to the difficulty of approaching it. Using jungle gyms, etc. as canopy observation systems to show the behavior of endangered arboreal land snails (the Sapporo Maimai) in 3D, this research determines the effects of deforestation and artificial forestation on gene transmission and habitat density, enabling the proposal of forest conservation methods that consider biodiversity in the canopy.
