| Outline of Final Research Achievements |
Population genetic analysis were done on the 632 specimens of Sika deer collected in the Kanto-Koshin area (462 in Gunma, 64 in Nagano, and 106 in Yamanashi prefectures). Twenty-one haplotypes were detected on the mitochondrial DNA (mtDNA) as a maternally inherited genetic marker. The mtDNA haplotype composition within the populations was greatly different between the east side and the west side across the Tone River. In Mount Asama, the emerging habitat of Sika deer, 8 different haplotypes were found in 26 individuals and genetic diversity was very high. The population analysis using 8 autosomal microsatellite markers also showed that the deer in this area could be roughly classified into two groups similarly to the result of mtDNA analysis. However, a small number of individuals showed the sign of migration between the two groups. Based on the above results, it was shown that the migration of individuals between the Akagi-Oze area and the Kanto mountainous area is at low level.
