Long‐term population decline of a genetically homogeneous continental‐wide top Arctic predator
Genetic analysis can provide valuable information for conservation programmes by unravelling the demographic trajectory of populations, estimating effective population size or inferring genetic differentiation between populations. Here, we investigated the genetic differentiation within Snowy Owls B...
