Symphyotrichum novae-angliae (Compositae) new alien species in Serbia.
Bibliographic record
Abstract
Symphyotrichum novae-angliae (Linnaeus) G. L. Nesom is native to almost every area in North America east of the Rocky Mountains, but excluding the far north of Canada as well as some of the southern States. Due to the attractive fl owers, numerous cultivars of have been developed. Furthermore, as a result of its increased usage in the garden, it has been introduced to many area beyond its natural range. In many places Symphyotrichum novae-angliae is escaped from cultivation and naturalized as an alien species. According to Euro+Med PlantBase there is a presumption that the species is introduced in the countries of the Former Yugoslavia. Based on our research in the fi eld and the studies of herbarium material, we have found that S. novae-angliae is present in Serbia, both as cultivated ornamental plants, as well as a naturalized alien species. We have registered this species on 25 localities that are situated in 18 UTM 10 km x 10 km squares. Twenty two of the localities refer to a small group of individuals which are cultivated, while the remaining 3 fi ndings relate to plants that have escaped from cultivation and have naturalized as a alien species. Size estimation of naturalized populations and detailed chorological data (locations of occurrences recorded with GPS, and distribution map presented at UTM grid squares of c. 10 km × 10 km) are presented.
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.
