Environmental ancient DNA has emerged as a molecular proxy for reconstructing past environments and ecosystems. Particularly, within the fields of paleolimnology and limnogeology, sedimentary ancient DNA (sedaDNA) has been widely used to investigate the genetic material preserved in sediment records. SedaDNA time-series data deliver detailed histories of species, ecosystems, and their relationship with climate and environmental changes, and human activities over decadal to millennial timescales. Our session invites presenters sharing their latest insights on a variety of sedaDNA related topics, such as: laboratory advances and innovative bioinformatic and statistical tools (including network statistics and AI). We encourage contributions with a special focus on the implications of DNA preservation and recovery for long-term paleo-reconstructions. While most sedaDNA records originate from cold or temperate environments, studies from subtropical and tropical areas, highlighting both challenges and successes, are very welcome.
