Insights from 180 years of mitochondrial variability in the endangered Mediterranean monk seal (<scp> Monachus monachus </scp>)
Abstract Mediterranean monk seals (MMS) are among the most endangered marine mammals on Earth. We screened mitochondrial variability (control region [CR1] and mitogenomes) of the species through a 180‐yr timeframe and extended by 20% ( n = 205) the number of samples from a previous investigation, in...

Abstract Mediterranean monk seals (MMS) are among the most endangered marine mammals on Earth.
