The paper identifies eastern Atlantic sources of medieval European walrus ivory using ancient DNA, revealing broader trade networks than previously thought.

This study uses ancient DNA to show that Atlantic bluefin tuna experienced a demographic decline and genetic bottleneck starting in 1900, with lower genetic diversity in modern compared to historical populations.

This study uses ancient DNA to show that mitochondrial introgression in Atlantic bluefin tuna has persisted for five millennia without significant anthropogenic impact.

This study uses whole genome analyses of Atlantic puffins to reveal complex population structure, identifying four genetically distinct clusters and a secondary contact zone, challenging current taxonomy.
