The Mongolian gazelle (
Procapra gutturosa
) is a representative ungulate
species of Mongolia that inhabits steppes. Their number and range decreased
during the last century, and the population has been suffered from occasional
demographic changes caused by human and environmental factors. During
the summer of 2005, we obtained genetic samples from gazelle carcasses
encountered along the international railroad between Russia and China,
to examine genetic diversity and its changes in relation to historical
demographic shifts. Gazelle genetic structure and diversity were investigated
using mitochondrial control region sequence. In the phylogenetic analysis,
we confi rmed that there are two genetic groups unrelated to geographical
location. We also showed the genetic structure of gazelles was unrelated
to existence of the railroad. Based on the genetic diversity indices and
demographic parameters, the population was suggested to have experienced
demographic expansion historically, and effect of known demographic
decline was not detected. |
