Marine ecosystem shifts with deglacial sea-ice loss inferred from ancient DNA shotgun sequencing

H. H. Zimmermann, K. R. Stoof-leichsenring, et al.

Discover how ancient DNA reveals a remarkable transition in marine ecosystems over the last 20,000 years in the Western Bering Sea, showcasing the impact of sea-ice loss on biodiversity. This groundbreaking research, conducted by Heike H. Zimmermann, Kathleen R. Stoof-Leichsenring, Viktor Dinkel, Lars Harms, Luise Schulte, Marc-Thorsten Hütt, Dirk Nürnberg, Ralf Tiedemann, and Ulrike Herzschuh, highlights the valuable role of ancient DNA in understanding climate change effects on ocean life.

Abstract
This study uses shotgun metagenomics of marine sedimentary ancient DNA from the Western Bering Sea to analyze ecosystem responses to sea-ice loss over the last ~20,000 years. The results show a shift from a sea-ice adapted late-glacial ecosystem (diatoms, copepods, codfish) to an ice-free Holocene ecosystem (cyanobacteria, salmon, herring). Ancient DNA is identified as a valuable tool for assessing long-term ecosystem responses to climate change, informing ocean and cryosphere risk assessments. Continuing sea-ice decline is predicted to impact carbon export and benthic food supply, potentially leading to northward species expansion.
