The European fire ant, <i>Myrmica rubra</i> (Linnaeus) (Hymenoptera: Formicidae), in the Credit River watershed
Bibliographic record
Abstract
The European fire ant, Myrmica rubra (Linneaus) (Hymenoptera: Formicidae), is an invasive species in Canada and the United States. Myrmica rubra has proven to be very hard to control once it has invaded an area, and preventing further spread of the species is important for moderating its negative effects. There are limited studies of this species in Ontario. We used pitfall traps to sample M. rubra at ten wetlands in the Credit River watershed and explored the relationships between three factors—disturbance, wetness, and proportion of urban land use surrounding the wetlands—and M. rubra incidence and abundance. Three of the ten sites had a very high abundance (>30,000 ants) of M. rubra. The proportion of surrounding urban cover and disturbance had strong positive relationships with both the incidence and abundance of M. rubra. Ecological and land use data predicting M. rubra presence and abundance can assist in identifying sites that may be vulnerable to future invasions. We recommend incorporating ant monitoring into existing long-term monitoring efforts in southern Ontario.
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.
