Outline of Final Research Achievements

A genome-wide analysis was carried out to investigate the level of genetic diversity and gene flow between populations of an endangered butterfly Melitaea scotocia. Using samples of wild and captive (house) populations had been preserved by the Japan Butterfly Conservation Society, 1388 SNP sites that are highly homologous to Glanville fritillary butterfly shot-gun sequences were identified. Genetic analyses revealed that house populations were genetically differentiated each other. Therefore, it is desirable to introduce a certain number of individuals from each house rather than introducing a large number of individuals from a specific house in outdoor butterflies of breeding breeders to maintain genetic diversity of wild populations.
