Short summary
This study reconstructs past marine eukaryotic communities in Storfjordrenna using sedimentary ancient deoxyribonucleic acid (DNA) metabarcoding. Biodiversity remained stable over the past 13,300 years, with changes during major climate transitions. Cercozoans and marine stramenopiles dominated, indicating ecological flexibility. These findings highlight the value of sedimentary ancient DNA for tracking long-term marine ecosystem changes.
