Here, we show key insights can be made about the physical origins of sedaDNA by integrating sedimentological and sedaDNA data into a sediment influx depositional model. We reconstruct contrasting taphonomic regimes of lacustrine, alluvial, terrestrial, and permafrost systems. Lacustrine systems show signals of regional catchment sources of sedaDNA, while alluvial, terrestrial, and permafrost systems show a greater influence of DNA from the immediate local environment. However, there is a prevalence of mixed ecosystem signals which may span a broad temporal timeframe if sediment reworking has occurred. The ability to distinguish between local and distal sources of sedaDNA is of major importance in the interpretation of taxonomic profiles to reconstruct paleoenvironments.<\/jats:p>","DOI":"10.1093\/pnasnexus\/pgag271","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T12:23:54Z","timestamp":1786364634000},"source":"Crossref","is-referenced-by-count":0,"title":["A
