Narwhal Genome Reveals Long-Term Low Genetic Diversity despite Current Large Abundance Size
The narwhal (Monodon monoceros) is a highly specialized endemic Arctic cetacean, restricted to the Arctic seas bordering the North Atlantic. Low levels of genetic diversity have been observed across several narwhal populations using mitochondrial DNA and microsatellites. Despite this, the global abu...
