Polygonum cuspidatum (Polygonaceae) Genetic Diversity in a Small Region of Eastern Kentucky
Bibliographic record
Abstract
Polygonum cuspidatum Sieb. & Zucc. is an invasive species that has spread across Britain, Europe, Canada, and the United States. Prior to this research, no analysis of genetic diversity within, or among, populations had been conducted in the United States, although population genetic diversity had been examined in Britain. An analysis of genetic diversity was carried out using Polymerase Chain Reaction (PCR)-based DNA fingerprinting on plant populations along two creeks in Rowan County, Kentucky. One creek was sampled at one-meter intervals and the other at intervals of one to nine km. The results of this analysis indicate that the plants along both of these creeks are genetically dissimilar and not clonal. The data did not support the hypothesis that P. cuspidatum is reproducing and dispersing by asexual means.
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.
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.
