New and interesting seaweed records from the Hakai area of the central coast of British Columbia: Phaeophyceae
Bibliographic record
Abstract
After 13 years of intensive sampling of seaweeds in the Hakai area of the central coast of British Columbia, we report on our collection of 67 of the approximately 100 brown algal species expected in the area based on known distributions. Most of these 67 species are distributed broadly in the northeast Pacific region. They were identified morphologically using primary and secondary literature and by sequencing the COI (cytochrome c oxidase subunit 1) gene in most instances. Laminaria yezoensis is recorded near its southern distribution limit, and Dictyoneurum reticulatum is recorded at its northern distribution limit. Although drift specimens of Postelsia palmaeformis have washed ashore, the species has not been found growing on Calvert Island but rather on the mainland just to the southeast. A number of species are reported for the first time in the northeast Pacific: we identified Hecatonema terminale, based on efforts to sequence several host species of red algae, an undescribed species of Acinetosporaceae previously identified erroneously as Hincksia granulosa that still requires a name, and undescribed species of Pylaiella and Ectocarpus. We describe as new to science Protohalopteris petersonii and Petrospongium munckiae and note a number of other species that require work before they can be identified to species, including a Ralfsia-like crust in the Chordariaceae. Distinctive haplotypes were found in at least four species, contributing to the uniqueness of this area.
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.

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.
