Abstract
Ammophila breoiligulata , American beachgrass, is the major stabilizing plant of the north and mid-Atlantic coastal dunes of the United States. During the past 15 years, A. breviligulata has experienced a dieout along the Atlantic seaboard with the coast of the state of Delaware being particularly devastated. Several abiotic and biotic factors have been contributed as possible causes of this dieout but none have proven conclusive. This study focused on the presence of plant parasitic nematodes and their relationship with A. breviligulata and other plant species that inhabit the dunes. Seven genera of plant parasitic nematodes were identified from two locations in Delaware. Two new undescribed species of Trilineellus and Meloidogyne were isolated from soil around A. breviligulata. Other genera include Xiphinema sp., Longidorus sp., Pratylenchus penetrans , Hoplolaimus sp., Helicotylenchus digonicus and Helicotylenchus multicinus . Most of these species have been shown to cause suppressed growth and root damage on corn and related grasses and were found in large enough numbers around beachgrass to account for symptoms associated with the dieout of this species.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
