Abstract
Detecting the presence of a parasite within its host is crucial to the study of host-parasite interactions. The <i>Schistocephalus solidus</i>-threespine stickleback pair has been studied extensively to investigate host phenotypic alterations associated with a parasite with a complex life cycle. This cestode is localized inside the stickleback's abdominal cavity and can be visually detected only once it passes a mass threshold. We present a non-lethal quantitative PCR (qPCR) approach based on detection of environmental DNA from the worm (eDNA), sampled in the fish abdominal cavity. Using this approach on two fish populations (<i>n</i>=151), 98% of fish were correctly assigned to their <i>S. solidus</i> infection status. There was a significant correlation between eDNA concentration and total parasitic mass. We also assessed ventilation rate as a complementary mean to detect infection. Our eDNA detection method gives a reliable presence/absence response and its future use for quantitative assessment of infection is promising.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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; both teacher heads agree on what is shown here.
