Outline of Final Research Achievements

Global climate changes will alter many local fauna and flora, especially inhabiting high latitude boreal area. Changes of fish fauna along Hokkaido and sequences of the secondary contact between two close Hexagramids species were investigated genetic ecologically. As a result, the first records of 9 species including the Northernmost records of 6 species were found from specimens collected with SCUBA Diving from Southern Hokkaido. This finding suggests that at the present, fish fauna in Hokkaido is changing to more temperate-zone type. The secondary contact between Hexagramids species produced hemi-clonal hybrids. Hemi-clonal genome can migrate hemi-clonal hybrid population and their maternal species population by "host-switching", is referred to as changes in the species of the sperm donor among hybrids employing (hemi-) clonal reproduction. Including this example of the secondary contact without genetic penetration, this study clarified a part of diversities by species contacts.
