Arctic Grayling 280x134 jpegAmong other science projects, biologists at Red Rock Lakes are restoring Arctic Grayling to the refuge with encouraging results.




Science guides management at Red Rock Lakes National Wildlife Refuge.  There are multiple on-going research projects being completed at Red Rock Lakes, most through partnerships with local universities.  Red Rock Lakes is important to academic research due to the location in the Greater Yellowstone Ecosystem, it's importance as a wildlife corridor connecting to the Bitteroot Range, the diversity of the refuge (habitats, elevation, and wildlife) and the general remoteness of the valley.    

Recent publications of work done at Red Rock Lakes include: (Click link for summary of each project.)

-- Recovery of Arctic grayling: The US Fish and Wildlife Service has recently been working to update the information on the population genetics of Arctic grayling in the upper Missouri River system in Montana and Wyoming. The project was 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.

The second component focused on the Arctic grayling population in the Big Hole River, Montana. The objectives were 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 was conducted by Dr. William Ardren, US Fish and Wildlife Service, Western New England Complex, Essex Junction, Vermont. The project completion date was December 2009.
