Abstract

350年以上生態学的に隔離された可能性をもつ,皇居産のアズマモグラ集団の形態学的,および分子遺伝学的特質を把握するため,頭骨の骨計測学的検討を進め,ミトコンドリアDNAのチトクロームbおよび12SrRNA遺伝子の塩基配列を明らかにし,他のアズマモグラ集団およびサドモグラと比較した.頭骨の形態において,皇居産は,ほかの関東地区集団と比較して,大きなサイズをもつことが明らかになった.主成分分析においては,皇居集団が,関東地方産アズマモグラの大型タイプとして,ひとつのクラスターをつくる可能性が示された.しかし,これはアズマモグラの種内変異以上の分離ではないことが推測された.一方,皇居集団は,東京都日野市集団との間に,チトクロームb遺伝子の塩基配列においては98.5%,12SrRNA遺伝子では98.7%という高いホモロジーを示した.

Since about 1630, the Imperial Palace has been biologically isolated from other habitats by the development and urbanization of Tokyo. We morphologically examined the skulls of the lesser Japanese mole (Mogera imaizumii) from the Imperial Palace and compared them with those from Kanto District, while the sequences of the cytochrome b and 12S rRNA genes were also analyzed to clarify the genetic status of this isolated population. The skulls from the Imperial Palace were much larger than those from Kanto District in the length items. We suggest that the Imperial Palace skulls morphologically may compose a cluster as a large body-sized type in Kanto District within the dots of Mogera imaizumii in charts of principal component analysis. The mitochondrial DNA sequences of the Imperial Palace population were highly homologous to those of other Tokyo population at the level of 98.5% in cytochrome b and 98.7% in 12S rRNA genes.
