Genetic diversity of the invasive plant <i>Coreopsis grandiflora</i> at different altitudes in Laoshan Mountain, China
Bibliographic record
Abstract
In order to understand the relationship between genetic diversity and the invasiveness of exotic plants, genetic diversity was studied in the invasive plant Coreopsis grandiflora Hogg. at different altitudes in Laoshan Mountain, Northern China. Coreopsis grandiflora has produced a great deal of damage in Laoshan Mountain. Its genetic diversity was examined using 16 random amplified polymorphic DNA (RAPD) primers, and 125 bands were collected from all individuals. The mean percentage of polymorphic loci (P%) was 39.54%, and the total percentage of polymorphic loci (P%) was 86.40%. The mean Shannon's Information index (H 0 ) was 0.2326 and the mean Nei's genetic diversity (H) was 0.1596. These results indicated a comparatively high genetic diversity in C. grandiflora in Laoshan Mountain. The genetic differentiation among populations (G ST ) was 0.3948, indicating that most genetic diversity occurs within populations. On the whole, the abundance and the genetic diversity of C. grandiflora decreased with increasing altitude. The high genetic diversity may be related to the invasion of C. grandiflora in Laoshan Mountain. Key words: Biological invasions, Coreopsis grandiflora Hogg., genetic distance, genetic diversity, random amplified polymorphic DNA (RAPD), sexual reproduction, Shannons information index

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.
