Allocation to sexual and asexual reproduction was uniform in spite of environmental gradients in case of the moss Polytrichum juniperinum in the low arctic
Bibliographic record
Abstract
Abstract The relative allocation within a plant species of asexual vs. sexual reproduction is predicted to vary according to changing environmental conditions. In bryophytes, sex expression is predicted to be reduced in unfavourable environments because sporophyte maturation is resource‒limited. The allocation between reproductive strategies in the bryophyte, Polytrichum juniperinum was examined in the low‒arctic Torngat Mountains (Labrador, Canada) in 2008/2009 along both an elevation and moisture gradient. Using genetic markers, no pattern was observed in the allocation between sexual and asexual reproductive strategies among the different environmental conditions. Although all populations showed evidence of sexual reproduction, effective sexual reproduction was depressed along both gradients. All populations showed high rates of fertilization among closely related ramets that resulted in inbreeding. This might limit the capacity to maintain high genetic diversity in local populations, which would be favoured in an environment experiencing warming.

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.
