Four centuries of commercial whaling eroded 11,000 years of population stability in bowhead whales

M. V. Westbury, S. C. Brown, A. A. Cabrera, H. E. Morales, J. Ma, A. Rey-Iglesia, A. S. Dyke, C. H. Scharff-Olsen, M. Scott, O. Wiig, L. Bachmann, K. M. Kovacs, C. Lydersen, S. Ferguson, F. Racimo, , E. Lorenzen

This study uses fossil data and modeling to show that commercial whaling caused genetic diversity loss in bowhead whales, threatening their resilience to future climate change.

Unprecedented shift in Canadian High Arctic polar bear food web unsettles four millennia of stability

J. Routledge, C. Sonne, R. J. Letcher, R. Dietz, P. Szpak

This paper analyzes carbon and nitrogen isotopes in polar bear bone collagen from the Canadian Arctic to show a recent shift in food web structure due to modern warming, contrasting with millennia of stability.

Sex and size matter: foraging ecology of offshore harbour porpoises in waters around Greenland

M. Louis, J. Routledge, M. P. Heide-Jorgensen, P. Szpak, E. Lorenzen

The paper examines sex and size differences in the foraging ecology of harbour porpoises using stable isotope analysis, finding females have higher trophic levels and larger ecological niches.
