Population genetics of Arctic
grayling in Montana
|
The US Fish and
Wildlife Service is currently working to update the information on the
population genetics of Arctic grayling in the upper Missouri River
system in Montana and Wyoming. The project is divided into two
components. For the first component, our general objective was to use
microsatellite DNA markers to more clearly characterize ancestral
relationships, genetic differentiation, and genetic diversity within and
among native and naturalized Arctic grayling populations in Montana and
Wyoming. The first component
of this project was completed in fall 2008 and a manuscript based on
this project is currently “In Press”.

The second component focuses on the
Arctic grayling population in the Big Hole River, Montana. The objectives
are to characterize the genetic diversity, effective population size, and
population structure of Arctic grayling in the Big Hole River based on
individuals collected during three different time periods (1980s, 1990s, and
2000s) using microsatellite DNA markers. This analysis is being conducted by
Dr. William Ardren, US Fish and Wildlife Service, Western New England Complex,
Essex Junction, Vermont. The estimated project completion date is December
2009.
