Abstract excerpt
Global changes in the marine Arctic ecosystem affecting the demography of fish and seal populations may also alter their anisakid parasite populations size, potentially leading to genetic erosion in gene pools. Contracaecum osculatum sp. B, an Arctic member of the C. osculatum (s.l.) species complex, parasitizes Arctic and sub-Arctic seals and fish. This study aimed to compare parasite genetic diversity across...
