The European fire ant (Hymenoptera: Formicidae) as an invasive species: impact on local ant species and other epigaeic arthropods
Bibliographic record
Abstract
Abstract Pitfall trapping revealed that the European fire ant, Myrmica rubra (Linnaeus) (Hymenoptera: Formicidae), represents an unusual example of a temperate invasive ant species. In British Columbia, Canada, M. rubra populations are associated with a decreased incidence and abundance of other ant species in three different plant communities when compared with M. rubra -free control areas. M. rubra represented more than 99.99% of the total ant fauna caught in the infested areas, and the numbers of M. rubra captured in the plant communities ranged from over 10 times to over 1300 times the total number of all ants collected in corresponding M. rubra -free areas. Total numbers of some taxa of insects and non-insect arthropods, including those likely to be competitors or prey of M. rubra , were reduced where the invasive species was present. Biodiversity indexes for the overall suite of captured arthropod species were lower where M. rubra was present in all three plant communities but most of this decrease can be attributed to the difference in the ant fauna.

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.
