| Research Abstract |
We conducted a case study aimed to reveal the effect of forest fragmentation history on species and genetic diversity in subtropical island ecosystem in Tokunoshima island. In this stage, we could not find the clear evidences of severe biodiversity loss in studied forests. However we found slight symptom of effects of forest fragmentation on regeneration process and gene flow process in some isolated forests. Conservation of remaining forests and rehabilitation of surrounding degraded forests should be needed to protect biodiversity.
