Vegetation mosaics, patch dynamics and alternate stable \nstates in an arctic intertidal marsh.
Bibliographic record
Abstract
Soil degradation occurs following loss of vegetative cover at both the landscape and individual patch scale at La Pérouse Bay, Manitoba. At the landscape scale, soils from vegetated patches had a higher infiltration rate, and higher moisture, organic content and nitrogen content, but lower salinity and bulk density, than comparable values for exposed mineral soils. These differences in soil properties resulted in higher establishment success of the forage grass, Puccinellia phryganodes, in vegetated than in mineral soils. At the patch scale, similar to the landscape scale, soil conditions because more adverse for plant growth with increasing patch size (2.5 to 40 cm diameter) following experimental grubbing, resulting in a decrease in the re-colonization potential of Puccinellia. Localized vegetation removal by geese limits plant-soil interactions resulting in areas of intact intertidal salt marsh changing to an alternate state of exposed mud flats, where soil conditions offer little possibility of re-vegetation.

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.
