Climatic control of peat erosion in a North Wales blanket mire
Bibliographic record
Abstract
Summary This study investigates the palaeoecology of a hummock‐and‐hollow complex from a partially eroded upland blanket mire at the Migneint, north Wales, UK. Three peat cores were collected and analysed for pollen and botanical macrofossils, two for peat humification and a third was radiocarbon‐dated. In the interpretation of the palaeoecological record particular attention was paid to the ecology of the moss Racomitrium lanuginosum. We delimit two periods in the development of the hummock‐hollow complex: an earlier period of climatically controlled blanket‐mire development; and a later period of mire erosion (initiated between c. 2000 and 1350 Cal. year BP) when ‘natural’ climatically controlled mire development was modified by excessive drying of the mire surface. The data support recent studies in suggesting that the development of British blanket mires is sensitive to climate change. However, climatically controlled blanket‐mire development appears to have been pre‐empted at the Migneint by the development of the erosion‐complex, the initiation of which coincides with the zenith of an extensive deforestation during the Late Bronze Age, Iron Age and Romano‐British periods.

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.
