Abstract:
Tropical and subtropical regions hold most of Earth's biodiversity. These regions have often been considered unsuitable for ancient environmental DNA (aeDNA) research due to assumptions about poor DNA preservation. Recent studies challenge this view: they show that aeDNA can persist and provide ecological insights under warm and humid conditions. We review aeDNA research across these regions, synthesising methodological and geographic patterns. We also identify obstacles related to preservation, reference databases, infrastructure, and research capacity. Despite challenges, tropical aeDNA is beginning to reveal past biodiversity trends, human impacts, and ecosystem resilience for up to a million years. Methodological refinements and inclusive collaborations in aeDNA research open powerful opportunities to reconstruct deep-time ecological histories in the world's most dynamic and threatened environments.
