The relative influence of microhabitat constraints and rock climbing disturbance to cliff face vegetation communities
Bibliographic record
Abstract
This study is the first to determine the relative influence of pre-existing microhabitat conditions vs. direct rock climbing disturbance to the cliff face vegetation communities of the Niagara Escarpment in southern Ontario. Climbed and unclimbed cliff faces were sampled quantitatively for vascular plant, bryophyte and lichen species richness, percent frequency and community composition, microtopographic feature size and frequency, and measures influencing microclimate. Results revealed that certain microhabitat conditions are related to increases in the richness and cover of cliff face vegetation, and that rock climbers select for different microhabitat conditions when establishing climbing routes. No decreases in vascular plant, bryophyte or lichen species richness or cover on climbed cliff faces were attributable to direct climbing disturbance. Pre-existing microhabitat conditions explained greater proportions of variation in vegetation community composition across unclimbed and climbed cliff faces than climbing disturbance. A policy is presented that permits new climbing route establishment with limited impact.

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.
