The paper develops the genC pipeline to estimate taxonomically resolved organic carbon sources in lake sediments and finds that environmental conditions, especially warming, drive OC variation, with terrestrial sources dominating.

This study uses sedimentary ancient DNA to reconstruct ancient viral communities in lake and marine environments over the last glacial cycle, revealing stable virus-host relationships and environmental influences.

The paper examines millennial-scale changes in plant metacommunity connectivity in Beringia using sedimentary DNA from lake cores, revealing shifts driven by climate and landscape changes.

The paper uses ancient metagenomics to show that loss of large mammals disrupted seed dispersal, contributing to mammoth-steppe collapse and informing Arctic rewilding.

The paper reconstructs plant interactions over 24,000 years in the Arctic, showing a shift from positive to negative interactions with woody encroachment.

This paper uses ancient metagenomics and network analysis to show that cryosphere loss over 18,000 years drove ecosystem shifts in the Tibetan Plateau, refuting top-down herbivore control and highlighting keystone plant species.
