Assessment of the order Rhodymeniales (Rhodophyta) from British Columbia using an integrative taxonomic approach reveals overlooked and cryptic species diversity
Bibliographic record
Abstract
Molecular-assisted alpha taxonomy using COI-5P and rbcL-3P was employed to reassess species diversity for the Rhodymeniales (Rhodophyta) in British Columbia. A total of 563 collections from British Columbia were resolved as 16 genetic species groups, whereas 13 were previously reported. Collections attributed to Botryocladia pseudodichotoma from British Columbia were resolved as distinct from collections of that species from California (type locality) and were assigned to Botryocladia hawkesii sp. nov. DNA sequence data also resolved an additional species of Fryeella. Although two species of Gloiocladia were recognized, genetic analyses resolved three: G. fryeana, G. laciniata, and Gloiocladia vigneaultii sp. nov. Data also resolved Gloiocladia media comb. nov. from California. For the genus Rhodymenia, where two species were expected, DNA sequence data resolved four. Both R. californica and R. pacifica were confirmed in British Columbia, whereas some collections field-identified as R. californica were genetically distinct and assigned to the novel species, Rhodymenia bamfieldensis sp. nov. Some collections initially identified as R. pacifica were assigned to the resurrected species R. rhizoides. Anatomical development for the monospecific genus Minium was also reassessed owing to that taxon’s assignment to the Fryeellaceae. Our investigation clarified the number of rhodymenialean species in British Columbia and resolved taxonomic and distributional uncertainties associated with some of these taxa.

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.
