Abstract

fetched live from OpenAlex

This thesis investigates patterns of sequence variation in Canadian Cnidaria for the DNA barcode region of the cytochrome c oxidase subunit 1 (COI) gene. As such, it begins development of a DNA barcode reference library for this phylum. This work confirms the COI gene region as an effective tool for delineating currently recognized species of cnidarians and revealing cryptic species. As well, this study shows the value of COI barcodes in the identification of newly collected specimens and morphologically unusable specimen fragments. A detailed analysis of the genus Cyanea explores the incidence of cryptic taxa, revealing high genetic diversity. The results from this study have implications for the utility of DNA barcoding both for documenting biodiversity and broadening our understanding of biogeographic patterns of Cnidaria

Not 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.
