Outline of Final Research Achievements

Studying the ecology of wild ungulates in the mountainous areas of Mongolia has been challenging due to difficulties in accessing their habitats and collecting analytical samples. This study, for the first time, investigated genetic diversity and genetic structure of endangered wild goats based on the sufficient number of samples. Mitochondrial and nuclear DNA analyses revealed that the wild goat population held a high level of genetic diversity with no bottleneck signatures and that genetic structure exited with a moderate level of connectivity among the observed genetic clusters. Given the ongoing habitat destruction due to exploitation of mineral resources and development, it is essential to conserve the corridor among the genetic clusters for protecting this species.

Academic Significance and Societal Importance of the Research Achievements

本研究により、野生ヤギの遺伝的多様性や遺伝構造について、十分なサンプル数に基づいた解析から明らかにすることができた。生息地で採集した糞からは、核DNAの解析に耐えうる十分なDNA量が抽出され、今後のモニタリング調査においても糞試料が有用であることが示された。野生ヤギは遺伝的多様性の高い、安定した集団であることが示唆されたが、生息地では鉱山開発やそれに伴う道路整備が進んでいることから、本研究の成果をベースに、今後も調査研究を継続することが重要である。
