Arctic_geneticUnderstanding genetic variation in Arctic species is critical to their conservation and effective management in this time of rapid environmental change. Genetic analyses can be used for a variety of purposes, from determining the history of species dispersal and diversification to evaluating the conservation status of a species of concern. As the range and abundance of species declines, the genetic variability needed to respond to novel challenges will also be reduced. A significant increase in our efforts to build temporally-deep and spatially-extensive specimen archives is needed. These specimens will provide a baseline of environmental conditions and, when combined with mapping of genetic structure, will be crucial for both effective recovery efforts for declining species and for predicting species response in the face of climate change and other human impacts in the Arctic.
