Abstract
Our study found that a water level close to the surface and a seedbed composed of bare peat or a <i>Sphagnum</i> carpet favored the germination of vascular species associated with pools in peatlands. A greenhouse experiment was conducted to study the impact of seedbed and water level on the germination and growth of 7 plant species associated with pools: <i>Carex limosa</i> L.<i>, C. magellanica</i> Lam. ssp. irrigua (Wahlenb.) Hultén<i>, C. oligosperma</i> Michx.<i>, C. pauciflora</i> Lightf., and <i>Rhynchospora alba</i> (L.) Vahl from the Cyperaceae family as well as <i>Drosera intermedia</i> Hayne (Droseraceae) and <i>Scheuchzeria palustris</i> L. (Scheuchzeriaceae). The 3 seedbeds tested were 1) bare peat; 2) a carpet of <i>Sphagnum cuspidatum</i> Ehrh. ex Hoffm. and <i>S. fallax</i> (Klinggr.) Klinggr. (Sphagnaceae); and 3) a carpet of <i>Cladopodiella fluitans</i> (Nees) H. Buch (Cephaloziaceae), common bryophytes along pool edges. Seedbeds were combined with 2 water levels (0 and 10 cm below the soil surface) in a complete factorial block design. Germination periods were generally longer when seeds were submitted to drier conditions and placed on <i>C. fluitans</i> carpets. Conditions favoring biomass production were more variable among species. These results will facilitate the identification of the best ecological conditions for successful establishment of pool edge species in the context of restoration projects, thereby increasing biodiversity and ecological value of restored peatlands.

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 it
