ABSTRACT The now‐extinct harp seal population that inhabited the Baltic Sea from Mesolithic to Iron Age is an enigma. It occurred outside species' contemporary Arctic range, likely deviated typical migratory behaviour, and experienced body size reductions dramatic fluctuations leading up its extinction. Here we use ancient DNA analyses shed more light on evolutionary history of population, including origin, timing colonisation, diversity factors contributing demise. We generated 49 eight...
Walrus ivory was a prized commodity in medieval Europe and supplied by Norse intermediaries who expanded across the North Atlantic, establishing settlements Iceland Greenland. However, precise sources of traded have long remained unclear, raising important questions about sustainability commercial walrus harvesting, extent to which Greenland were able continue mounting their own long-range hunting expeditions, degree they relied on trading with various Arctic Indigenous peoples that starting...
Rapid global warming is severely impacting Arctic ecosystems and predicted to transform the abundance, distribution genetic diversity of species, though these linkages are poorly understood. We address this gap in knowledge using palaeogenomics examine how earlier periods influenced Atlantic walrus (Odobenus rosmarus rosmarus), a species closely associated with sea ice shallow-water habitats. analysed 82 ancient historical mitochondrial genomes (mitogenomes), including now-extinct...
