Genetic structure among continental and island populations of gyrfalcons
Abstract Little is known about the possible influence that past glacial events have had on the phylogeography and population structure of avian predators in the Arctic and sub‐Arctic. In this study, we use microsatellite and mitochondrial control region DNA variation to investigate the population ge...
