Where is the highest density of strict endemic species typically found in Japan?
Answer
Smaller, more isolated islands away from the main island of Honshu.
When examining the distribution map of species strictly confined to Japanese territory, a clear pattern emerges indicating that the highest concentration of these unique endemics resides on the smaller, more isolated islands. These remote locations have historically provided the necessary degrees of isolation required for speciation events to occur most prominently, separated from gene flow that might otherwise occur on larger landmasses. This pattern contrasts subtly with species like the Green Pheasant, which has a broader distribution across the larger main islands, offering a wider geographical buffer against localized catastrophic events.
