Seasonality of the red algal crust ‘Petrocelis franciscana’(Gigartinales, Rhodophyta) on boulder‐strewn shores of southern British Columbia, Canada
Bibliographic record
Abstract
SUMMARY The red algal crust,‘Petrocelis franciscana’ Setchell et Gardner [= tetrasporophytic phase of Mastocarpus papillatus (Agardh) Kützing] exists as discrete patches on boulders throughout the intertidal zone at Burrard Inlet in Vancouver (mainland British Columbia) and at Sooke, Vancouver Island (British Columbia). This study photographically quantifies monthly surface area of 60 individual crusts over 12‐ and 18‐month periods, respectively, at the two sites. Conspicuous seasonal fluctuations in ‘Petrocelis’ abundance and relatively low survivorship of crusts sampled suggest that not all crusts are as static and as long‐lived (> 25 years) as previously suggested. Herbivory, sloughing of senescing tissue and abiotic factors visibly reduce ‘Petrocelis’ abundance in fall and winter; regeneration of lost crust tissue and relatively rapid crust growth occur from spring to early fall.

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.
