Winds of Change: Charting a Pathway to Ecosystem Monitoring Using Airborne Environmental DNA
Bibliographic record
Abstract
ABSTRACT Airborne environmental DNA (airborne eDNA) analysis leverages the globally ubiquitous medium of air to deliver broad species distribution data and support ecosystem monitoring across diverse environments. As this emerging technology matures, addressing critical challenges and seizing key opportunities will be essential to fully realize its potentially transformative impact. In June 2024, the Southern eDNA Society convened over 100 researchers, industry leaders, and biodiversity management stakeholders in a landmark workshop to evaluate the current state of airborne eDNA research and chart a course for future development. Participants explored opportunities for integrating airborne eDNA into existing monitoring systems, but they unanimously agreed that research must first be applied to improving understanding of airborne eDNA ecology. The workshop emphasized the importance of collaborative engagement with stakeholders—including government agencies, Indigenous communities, and citizen scientists—to ensure practical and ethical implementation. This summary highlights current challenges and actionable recommendations, including improving our understanding of airborne eDNA ecology, harmonizing sampling methodology (e.g., devices, materials, sampling density, duration), identifying and mitigating sources of error, and fostering early, sustained stakeholder collaboration. By addressing these challenges, airborne eDNA analysis can become a transformative tool for biodiversity, biosecurity, and conservation monitoring on a global scale. Its ability to detect diverse taxonomic groups—including fungi, plants, arthropods, microbes, and vertebrates—positions airborne eDNA as a pivotal technology for holistic terrestrial biodiversity assessments that transcend traditional, species‐focused monitoring approaches.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
