Conservation genetics and habitat characteristics of Few-flowered Club-rush (Trichophorum planifolium (Spreng.) Palla), an endangered woodland sedge in Canada
Bibliographic record
Abstract
Trichophorum planifolium, like many Canadian species-at-risk, reaches the northern extent of its range in Canada, but is common farther south in the United States. Peripheral populations may be important sources of adaptive and evolutionary potential, possessing unique genetic diversity and/or adaptations to local conditions. However, such populations are typically small and isolated and may therefore be susceptible to extinction. Using microsatellite markers, we compared the level and spatial distribution of genetic diversity and environmental characteristics between the Canadian and American populations of T. planifolium. Overall, low diversity and high inbreeding were detected, with all populations exhibiting comparable levels. This suggests inbreeding depression is not limiting recruitment in the Canadian population, as previously hypothesized. We also found high differentiation between populations and unique environmental conditions at the northern range margin. Consequently, efforts to bolster genetic diversity in the Canadian population are not presently warranted and should be avoided in the future.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
