Spread of the Invasive Alien Vine Vincetoxicum rossicum: Tradeoffs Between Seed Dispersability and Seed Quality
Bibliographic record
Abstract
The relationship between seed weight, dispersal ability and seed “quality” was tested for the seeds of pale swallow-wort Vincetoxicum rossicum (Kleo.) Barb., an invasive alien vine. In a field release, small seeds traveled significantly farther than large seeds. In one of two greenhouse experiments, large seeds were significantly more likely to germinate than small seeds. Seed weight also had a significant effect on seedling size at the time of harvest, but only when the seeds were grown in competition with a mixture of grasses. Seeds containing more than one embryo produced greater total seedling weight in the absence of competition, but polyembryony was not advantageous when seedlings were grown with grasses. We argue that if long-distance dispersers are less likely to germinate or survive, measured seed dispersal curves could lead to overestimation of the rate of spread of invasive plants.

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.
