First records of non-indigenous cyclopoid copepod Thermocyclops crassus (Fischer, 1853) in Eastern Canada
Bibliographic record
Abstract
We report the first records for the Eurasian zooplankton species Thermocyclops crassus (Fischer, 1853) (Copepoda, Cyclopoida) from two freshwater sites in eastern Canada collected between 2020 and 2022.Thermocyclops crassus were found at high densities (between 8 10 3 and 2 10 5 adults/m 3 ) in Lake St. Pierre on the St. Lawrence River, Qubec, but at very low densities (between 0.3 and 0.7 adults/m 3 ) in Wentzell's Lake on the LaHave River system, Nova Scotia.We discuss possible introduction pathways for both sites as well as the need for enhanced biosurveillance and increased public education in eastern Canada.

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.
