A New Species of Thorny-headed Worm (Acanthocephala: Neoechinorhynchus), a Parasite rom White Sucker (Catostomidae) from Oneida Lake
Bibliographic record
Abstract
This study is a result of extensive fish parasite survey work in North America with a heavy emphasis on water bodies in New York state. One objective was to assess the diversity of acanthocephalans which are also known as thorny-headed worms. My study specifically branched out of the bigger study when Dr. Reyda, other students and I encountered a new species of acanthocephalan from two localities in New York, Oneida Lake and Sandy Creek, an eastern tributary of Lake Ontario. This new species appears to be rare since it was only seen in a few white suckers out of over 150 examined in total. Permanent slides were made of the parasite which was then examined and measured using a light microscope. This made it possible to distinguish the new species from the many other species of Neoechinorhynchus in North America that parasitize fishes. This worm was distinguished from other species of Neoechinorhynchus in white sucker in its possession of an unusually large cement gland in males. Other comparisons are currently underway in the laboratory. The unique nature of this species is further supported by DNA sequence data of the large ribosomal subunit that was obtained in a separate, ongoing study. This project is still underway as further work is needed and more samples of the parasite are needed for it to be formally described as a new species. The significance of this work is to show that there are still new species of organisms waiting to be discovered throughout the United States.

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.
