Testing hair sampling on power poles as a potential method for DNA identification and monitoring brown bears
Genetic methods based on sampling of feces and hairs to study brown bears have become the method of choice for many wildlife researchers and managers. Feces and hairs are the most common sample material for DNA identification of individual bears. While the collection of feces and hairs in the field...
