A State‐Of‐The‐Art Review of Aquatic eDNA Sampling Technologies and Instrumentation: Advancements, Challenges, and Future Prospects
Bibliographic record
Abstract
ABSTRACT The field of environmental DNA (eDNA) analysis has revolutionized our ability to detect and monitor biodiversity in aquatic and terrestrial ecosystems. However, traditional eDNA sampling methods often present limitations in terms of temporal and spatial coverage, resulting in a loss of resolution associated with infrequent events or those prohibitive to onsite fieldwork. In recent years, the emergence of autonomous eDNA sampling technology has provided researchers with a powerful tool for collecting high‐resolution genetic data, overcoming many of the challenges associated with manual sample acquisition. This review focuses exclusively on eDNA technologies designed for the collection and preservation of water samples, to provide a comprehensive overview of the current landscape of aquatic autonomous eDNA sampling technology and instrumentation. A new era of instrument development and capabilities is emerging; the result of knowledge gained through experience with long‐tested marine biological observation instrumentation. Lastly, we highlight current research to develop an in situ eDNA analytical capability, as well as explore the challenges and future prospects associated with this rapidly evolving field.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
