Schmidtea polychroa Schmidt 1861
Bibliographic record
Abstract
Schmidtea polychroa (Schmidt, 1861) (Fig. 1) Comparative discussion. Schmidtea polychroa is a freshwater planarian with a Europe-wide distribution (Dahm & Gourbault, 1978) that is also present in the Azores (Malhao et al. 2007) and has been introduced into Canada (Ball, 1969; Mettrick et al. 1970; Boddington & Mettrick, 1974). In the Iberian Peninsula, the species was previously recorded in Catalonia and Valencia (both in eastern Spain). Only two populations are known from central Spain (Baguñà et al. 1981). We found new populations in the river Miño (Galicia, northwestern Spain), the river Esla (province of León, northern sector of the Iberian Peninsula), and new localities in the basin of the river Ebro, Valencia, and the provinces of Barcelona and Girona. The species has also been collected in Barcelona from the "Viver dels Tres Pins", a plant nursery with several ponds, where it coexists with Schmidtea mediterranea. The new records considerably extend the known distribution range of the species in the Iberian Peninsula (Fig. 1).
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.
