Parasites of the Deepwater Sculpin (Myoxocephalus thompsonii) Across Its Canadian Range
Bibliographic record
Abstract
Deepwater sculpin (Myoxocephalus thompsonii) were collected from 19 lakes across the species' distribution in Canada and examined for parasites. Six helminth species (Crepidostomum farionis, Bothriocephalus cuspidatus, Proteocephalus sp., Cyathocephalus truncatus, Raphidascaris acus, and Echinorhynchus salmonis), 1 crustacean species (Ergasilus nerkae), and 1 molluscan species (glochidia) parasitized these hosts. Crepidostomum farionis, Proteocephalus sp., R. acus, E. nerkae, and the glochidia represent new parasite records for this host species. Overall parasite prevalence was 78.0% while mean intensity was 6.1 +/- 7.1 SD. Bothriocephalus cuspidatus was the most prevalent parasite and was recorded from 62.2% of the deepwater sculpin and found in 17 of the 19 lakes. The low-productivity habitat of this host limits the parasites available for transmission, and the infra- and component communities were generally species poor. With the exception of the Proteocephalus sp., all of the helminth parasites recovered have been reported as adults in lake trout (Salvelinus namaycush) or burbot (Lota lota), suggesting that, in the lakes where they occur, deepwater sculpin may play an important role in energetic transfer and parasitic transmission to higher trophic levels.
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; a candidate call from one teacher head, not a consensus.
