Uncovering past and present biodiversity using ancient and environmental DNA from sediments
Session ID#: 80174
Session Description:
Ancient and modern sediments and soils contain a wealth of (paleo)ecological information. Recent advances in DNA metabarcoding and high-throughput sequencing have facilitated efficient use of environmental DNA (eDNA) and sedimentary ancient DNA (sedaDNA) as an invaluable recorder of past and present biodiversity. Identifying meaningful spatial and/or temporal ecological patterns from sedaDNA or eDNA signatures is challenging but critical for understanding and predicting long-term ecosystem changes. In this session, we invite contributions from across disciplines that take advantage of sedaDNA or eDNA from sediments, soils, or other deposits to infer temporal or spatiotemporal dynamics from local to geographically broad scales. This session will bring together paleo- and modern researchers who are applying molecular techniques to sediments or soils across all environments, covering a range of taxonomic groups, and spanning Quaternary to recent timescales to share methodological advances and novel applications in this growing interdisciplinary field.
