  "summary": "Saimaa ringed seals (Pusa saimensis) are a highly endangered freshwater pinniped species. Due to their unique evolutionary history and intense persecution over the last century, their population size and genetic diversity are low. Although mitochondrial and genome-wide variation have been extensively investigated, the paternal evolutionary history and genetic diversity of the Y chromosome remain…",
